The first lunar exploration mission in the history of ISRO was Chandrayan. It was launched in the year 2008 and since then 2 more follow missions have been launched under this program. 

The second follow-up mission was launched in 2019 and followed by a third follow-up mission in 2023. The success of Chandrayaan 3 has marked the country in different records such as the first country to land on the moon’s south pole and the most cost-effective execution. 

It was launched on July 14, 2023, from Sriharikota’s SDSC SHAR and landed successfully on 23rd August 2023. The mission will be carried down for 14 Earth days i.e. the Rover on the ladder will roam around the moon and study its surface for 14 days. This successful attempt has made India very sure of further development and planned missions for the Moon.

Chandrayaan-3 is India’s ambitious space mission which has made India proud. It was a successful space mission aimed to conduct a soft landing at the lunar south pole of the moon through the Vikram Lander. The spacecraft is also equipped with a Rover Pragyan consisting of payloads to study the moon’s surface. Apart from this, there were 9 sensors in the Lander.

Talking about the Payloads, there were 4 payloads in the lander namely ChaSTE, ILSA, RAMBHA, and LRA. 2 Rover payloads were APXS and LIBS. The propulsion module also contains a payload i.e. SHAPE. These payloads are designed to study the moon’s surface.

Chandrayaan-3 was active for 14 Earth days in the presence of the sun. After which, the Lander and the Rover were kept to sleep on 2 September because they could not function in the absence of sunlight. Later, efforts were made to wake Lander and Rover when the sunlight hit the moon’s surface. But ISRO revealed that there were no signals from the Lander and Rover.

Despite this, the project was a successful one and it has marked the name of India in Golden words in the history of Space.

Hon’ble Prime Minister of India has named the landing spot of Chandrayaan-3 as Shiv Shakti Point.

Chandrayaan-3 is the most successful follow-up mission in the history of Indian space missions. It was followed by the successful Chandrayaan 1 and partly successful Chandrayaan 2. It has made a successful soft landing on the lunar surface and made India the fourth country to land on the lunar surface. 

It also marked India as the first country to land on the Moon’s south pole. It examined the presence of water and also gathered some valuable scientific information and data about its mineral composition and its geology. 

One of the main objections to this lunar mission was to make a soft landing. The Rover ‘Pragyan” will roam on the lunar surface for 1 Lunar day (Around 14 Earth Days). 

The cost of Chandrayaan 3 is much less than the previous attempt which is around INR 615 Crores making it the most cost-effective lunar mission. 

On 7th September 2019, ISRO’s Chandryaan 2 crashed while attempting a soft landing on the lunar surface. Since then, the Indian Space Research Organisation decided to build a successor to the Chandrayaan 2.

  • 06 July 2023 – Chandryaan 3 is scheduled to launch on July 14, 2023, at 14:35 Hrs. IST from the Second Launch Pad, SDSC-SHAR, Sriharikota.
  • 07 July 2023 – Vehicle electrical tests completed. 
  • 11 July 2023 – The ‘Launch Rehearsal’ simulation the launch preparation and process lasting 24 hours was concluded.
  • 14 July 2023 – LVM3 M4 vehicle successfully launched Chandrayaan-3 into orbit. Chandrayaan-3, in its precise orbit, started its journey to the Moon.
  • 15 July 2023 – The first orbit-raising manoeuvre was performed at ISTRAC/ISRO, Bengaluru. The spacecraft was in 41762 km x 173 km orbit.
  • 17 July 2023 – The second orbit-raising manoeuvre was performed. The spacecraft was in 41603 km x 226 km orbit.
  • 25 July 2023 – The last orbit-raising manoeuvre was performed.
  • 01 August 2023 – The spacecraft entered the translunar orbit.
  • 05 August 2023 – Chandrayaan-3 was successfully inserted into the lunar orbit.
  • 14 August 2023 – The mission was in the orbit circularisation phase. 
  • 17 August 2023 – The Lander Module was successfully separated from the Propulsion Module.
  • 23 August 2023 – Chandrayaan-3 successfully reached its destination Chandrayaan-3 completed soft-landed on the moon. Congratulations, India!
Chandrayaan-3 Mission: Vikram Lander is set into sleep mode around 08:00 Hrs. IST today. Prior to that, in-situ experiments by ChaSTE, RAMBHA-LP and ILSA payloads are performed at the new location. The data collected is received at the Earth. Payloads are now switched off.… pic.twitter.com/vwOWLcbm6P — ISRO (@isro) September 4, 2023

The cost of this mission was around 386 crores a lot less than any other space agency. The most prominent discovery of this mission was the presence of water molecules in the lunar south pole. It stopped communication with the base on 28 August 2009 and was declared over.

Chandrayaan-2 was followed by a second mission that was launched on 22 July 2019. It was successfully inserted into the lunar orbit on 20 August 2019 but failed to make a soft landing on the lunar surface on 6th September 2019 just 2.1 km away from the surface. However, it was declared partly successful because the orbiter was still functional for around 7.5 years.

Below is a perfect essay on Chandrayaan-3 for School Students:

India continues to make giant strides in space exploration with its third lunar mission, Chandrayaan-3. This ambitious venture is aimed at reinforcing India’s position as a significant player in global space endeavors.

The Chandrayaan Legacy “Chandrayaan” translates to “moon vehicle” in Hindi. The legacy began with Chandrayaan-1, India’s first lunar probe, which orbited the moon in 2008, marking India as the fourth nation to touch the moon’s vicinity. It was followed by Chandrayaan-2 in 2019, an ambitious mission with an orbiter, a lander, and a rover. Despite facing challenges with its landing phase, the orbiter continues to send valuable data back to Earth.

The Chandrayaan-3 Mission’s Architecture

Chandrayaan-3’s design builds on previous missions. Unlike Chandrayaan-2, it concentrates on the lander and rover, utilizing the operational Chandrayaan-2 orbiter for efficient communication.    Chandrayaan-3: A New Hope Continuing the series, Chandrayaan-3 is seen as a beacon of hope and a symbol of India’s technological persistence. It is set to further India’s quest to understand the moon, especially the intriguing South Pole region. With an improved lander design and the Pragyan rover, Chandrayaan-3, unlike its predecessor, will not be accompanied by an orbiter. Instead, it will leverage the still-active orbiter of Chandrayaan-2 for communications.

Key Objectives of Chandrayaan-3 

ISRO has outlined three principal objectives for the Chandrayaan-3 mission:

  • Soft and Safe Landing – The paramount objective is to achieve a gentle and secure touchdown on the moon’s terrain, underscoring India’s progress in space technology.
  • Rover Operations – Once on the moon, the Pragyan rover is designed to traverse the challenging terrain, gathering invaluable data about the lunar surface.
  • Scientific Exploration – Beyond the engineering feats, the mission will concentrate on scientific investigations of the Moon’s composition, including the study of soil, water, and other elements.

Scientist Behind Chandrayaan-3 

Several eminent scientists and engineers have been instrumental in the conception and realization of Chandrayaan-3:

  • S Somnath , ISRO Chairman
  • P VeeraMuthuVel, Project Director of Chandrayaan-3
  • S Unnikrishnan Nair, Director of Vikram Sarabhai Space Centre
  • A RajaRajan, Chairman of Launch Authorization Board
  • M Sankaran, Director of U R Rao Satellite Centre

Challenges of Chandrayaan-3

  • Soft Landing – Achieving this on the rugged lunar South Pole was challenging.
  • Rover Navigation – Ensuring the Pragyan rover’s efficient navigation was crucial.
  • Space Environment Hazards – Conditions like space weather and micrometeoroid impacts had to be considered.

Chandrayaan-3: All you need to know about the mission and what happens after its successful Moon landing

What is a soft landing, why did india send chandrayaan-3 to the moon's south pole and what happened after the landing was accomplished we explain..

purpose of chandrayaan 3 essay

India’s Moon mission Chandrayaan-3 scripted history by successfully landing on the lunar surface at 6:04 pm on August 23. With the Lander accomplishing a ‘soft landing’ on the Moon’s south pole, India becomes the only country to have ever done so. A rover, which is a small vehicle that is meant to move around on the Moon’s surface, then came out of the Lander. On August 24, ISRO released a video of how this happened on X.

… … and here is how the Chandrayaan -3 Rover ramped down from the Lander to the Lunar surface. pic.twitter.com/nEU8s1At0W — ISRO (@isro) August 25, 2023

When Chandrayaan-3 took off for the Moon on July 14, we explained the basics of the mission – how a mission launches into Space, what the Chandrayaan-1 and Chandrayaan-2 missions were, etc. You can click here to read it . Here, we further explain why a ‘soft landing’ was crucial to the mission, what makes landing on the south pole a difficult feat, and what is to happen after the landing.

What is a soft landing, and why did Chandrayaan-3 land on the south pole?

According to ISRO, the mission’s three objectives were to demonstrate a safe and soft landing on the lunar surface, to demonstrate a Rover roving on the Moon and to conduct in-situ scientific experiments.

Soft landing simply means landing at a gentle, controlled speed to not sustain damage to a spacecraft. Amitabha Ghosh, a scientist for NASA’s Rover mission to Mars, explained it in The Indian Express thus : “Imagine a spacecraft hurtling through space, at 10 times the speed of an airplane, having to nearly come to a standstill in order to land gently on the Earth — all in a matter of a few minutes and, more importantly, without any human intervention. This, in a nutshell, is a soft landing.”

Doing so showcases a spacecraft’s technical capabilities. The landing site is near the south pole of the moon at 70 degrees latitude.

All of the previous spacecraft to have landed on the Moon have landed in the region near the Moon’s equator, firstly because it is easier and safer here. The terrain and temperature are more conducive for a long and sustained operation of instruments. Sunlight is also present, offering a regular supply of energy to solar-powered instruments.

Festive offer

The polar regions of the Moon, however, are different. Many parts lie in a completely dark region without sunlight, and temperatures can go below 230 degrees Celsius. This creates difficulty in the operation of instruments. In addition, there are large craters all over the place.

Here's how the Chandrayaan-3 reached the lunar orbit and how it plans to descend to the Moon's surface.

As a result, the polar regions of the Moon have remained unexplored. The extremely cold temperatures could mean that anything trapped in the region would remain frozen in time, without undergoing much change. The rocks and soil in Moon’s north and south poles could therefore provide clues to the early Solar System.

Notably, Chandrayaan-2 also planned to land in this region in 2019, but it was not able to accomplish a soft landing and lost contact after it hit the surface.

Why was Chandrayaan-2 unable to land correctly, and what has changed since then?

Subsequent analyses reported that there were both software and hardware problems in 2019’s Chandrayaan-2. Isro chairperson S Somanath recently said the changes to the current mission were “failure-based.” He said, “Instead of a success-based design in Chandrayaan-2, we are doing a failure-based design in Chandrayaan-3 —we are looking at what can go wrong and how to deal with it.” Some of the changes that have been made are :

*Chandrayaan-2 lost control over its descent around 7.2 km from the surface of the Moon. Its communications system relayed data of the loss of control up to around 400 m above the surface. The Lander had slowed down to about 580 km/hr when it crashed.

A Lander does not have wheels; it has stilts, or legs, which are supposed to touch down on the lunar surface, the legs of Chandrayaan-3 have been strengthened to ensure that it would be able to land, and stabilise, even at a speed of 3 m/sec, or 10.8 km/hour.

*The prospective landing site had its range increased, this time. Instead of trying to reach a specific 500mx500m patch for landing as targeted by Chandrayaan-2, the current mission was given instructions to land safely anywhere in a 4kmx2.4km area.

*The Chandrayaan-3 Lander carried more fuel than Chandrayaan-2. This was done to ensure that the Lander is able to make a last-minute change in its landing site if it needs to.

*The Chandrayaan-3 Lander has solar panels on four sides, instead of only two in Chandrayaan-2. This was to ensure that the Lander continued to draw solar power, even if it landed in a wrong direction, or tumbled over. At least one or two of its sides would always be facing the Sun, and remain active.

What needed to happen for Chandrayaan-3 to land successfully?

The critical technical manoeuvre that the Chandrayaan-3 Lander had to perform on August 23, when it entered the final 15 minutes of its attempt to make a soft landing on the Moon, was to transfer its high-speed horizontal position to a vertical one — in order to facilitate a gentle descent on to the surface.

After Chandrayaan-2 failed in its soft landing mission, K Sivan, then chairman of ISRO, described this process as “15 minutes of terror” for them. It includes four phases:

1. The Rough Braking phase includes reducing the lander’s horizontal velocity from a range of 1.68 km/sec (more than 6,000 km/h) at a height of 30 km from the lunar surface, to almost zero for a soft landing at the designated site. This has to be done with precision, within certain durations. Read this explainer for a more detailed explanation .

2. At a height of 7.42 km from the surface, the lander is to go into an “attitude hold phase” lasting around 10 seconds, during which it should tilt from a horizontal to a vertical position while covering a distance of 3.48 km.

3. The “fine braking phase” lasts around 175 seconds, during which the lander is to move fully into a vertical position. It is to traverse the final 28.52 km to the landing site, the altitude will come down to 800-1,000 m, and it would reach a nominal speed of 0 m/sec. It was between the “attitude hold phase” and the “fine braking phase” that Chandrayaan-2 lost control and crashed.

4. “Terminal descent” is the final stage, when the spacecraft is supposed to descend totally vertically onto the surface.

And finally, what will happen after Chandrayaan-3’s successful landing on the Moon?

Spacecraft are often carrying certain instruments and experiments with them (called payloads) that observe and record what is happening in Space. This information is then relayed to Earth for scientists to analyse and study.

The six payloads on the Vikram lander and rover Pragyan remain the same as the previous mission. There will be four scientific payloads on the lander to study lunar quakes, thermal properties of the lunar surface, changes in the plasma near the surface, and a passive experiment to help accurately measure the distance between Earth and the Moon. The fourth payload comes from NASA.

There are two payloads on the Rover, designed to study the chemical and mineral composition of the lunar surface and to determine the composition of elements such as magnesium, aluminium and iron in the lunar soil and rocks.

For a detailed analysis of these experiments, and how they build on findings of the previous Chandrayaan missions (Chandrayaan-1 and Chandrayaan-2), read our explainer here.

Chandrayaan 3: Mission Overview, Objectives, Goals, Lunar South Pole Landing, Duration

Chandrayaan 3

Chandrayaan 3 is a continuation of the Chandrayaan mission, aiming to demonstrate the complete capability of safe landing and exploration on the lunar surface. It comprises a Lander module, a Rover, and a Propulsion module. 

Working of Chandrayaan 3 

Chandrayaan 3 consists of an indigenous Lander module (LM), a Propulsion module (PM), and a Rover, with the goal of developing and demonstrating new technologies necessary for interplanetary missions.

  • The Lander is designed to softly land at a specified lunar site and deploy the Rover, which will conduct in-situ chemical analysis of the lunar surface during its mobility. 
  • Both the Lander and the Rover carry scientific payloads to perform experiments on the lunar surface. 
  • The primary function of the Propulsion module is to transport the LM from launch vehicle injection to the final lunar orbit of 100 km and then separate from the LM. 
  • Additionally, the Propulsion module houses a scientific payload for post-separation operation. 
  • The GSLV-Mk3 launcher has been selected for Chandrayaan-3, which will place the integrated module in an elliptic parking orbit of approximately 170 x 36,500 km. 

The Propulsion module will transport the Lander and Rover to a lunar orbit of 100 km. 

  • It also carries the SHAPE payload, which will study Earth’s spectral and polarimetric measurements from the lunar orbit. 
  • The Lander payloads include Chaste for thermal conductivity and temperature measurements, ILSA for seismic activity, LP for plasma density estimation and a passive Laser Retroreflector Array for lunar laser ranging. 
  • The Rover payloads consist of APXS and LIBS for analyzing the elemental composition near the landing site.

Mission Objectives of Chandrayaan 3

The mission objectives of Chandrayaan 3 are to demonstrate a safe and soft landing on the lunar surface, showcase Rover’s mobility on the Moon, and conduct in-situ scientific experiments. 

  • To achieve these objectives, the Lander incorporates advanced technologies such as altimeters, velocimeters, inertial measurement systems, propulsion systems, navigation and guidance systems, hazard detection and avoidance systems, and landing leg mechanisms.

Goals of India’s Moon Mission 

  • The primary goal of India’s moon missions is to advance lunar exploration. ISRO aims to conduct scientific research and map its surface. 
  • The mission consists of three parts: the propulsion module, the lander module and the rover. Each component plays a crucial role in enabling ISRO to accomplish its objectives.

What are Chandrayaan Missions of India 

Chandrayaan missions are specifically designed for lunar exploration. 

  • Chandrayaan-1, launched in 2008, aimed to create a detailed three-dimensional atlas of the Moon’s near and far sides while conducting chemical and mineralogical mapping with high resolution. It made significant discoveries, such as detecting water and hydroxyl on the lunar surface and confirming the presence of ice in the North Polar region.
  • Chandrayaan-2, launched in 2019, consisted of an Orbiter, Lander and Rover. Although the lander and rover experienced partial success due to the crash on the lunar surface, the Orbiter successfully collected valuable data, including the discovery of water signatures across all latitudes.
  • The main objective of Chandrayaan 3 is to demonstrate India’s technical capabilities and achieve a successful soft landing on the moon. This landing requires precise control to bring the spacecraft from high speeds to a gentle touchdown without human intervention. The scientific payloads carried by the lander and rover are similar to those of the previous mission, focusing on studying lunar quakes, thermal properties, plasma changes near the surface and accurately measuring the Earth-moon distance. 

Why was the Lunar South Pole Chosen as the Landing Site of Chandrayaan 3?

The chosen landing site for Chandrayaan 3 is near the lunar south pole, as this region offers unique characteristics for deep space scientific discoveries. 

  • It holds promise for studying lunar polar volatiles, which are chemical elements or compounds that melt or evaporate at moderately warm temperatures. 
  • Understanding their distribution on the moon, especially elements like Hydrogen and Oxygen, could significantly impact future deep space exploration and reduce reliance on Earth for supplies.

How much time it will take for Chandrayaan 3 to Reach the Moon?

The journey of the lander to the moon is expected to take approximately 42 days. 

After launching into Earth’s orbit, the spacecraft will gradually increase its orbit through a series of maneuvers to escape Earth’s gravity and slingshot toward the moon. Upon reaching close proximity to the moon, the spacecraft will undergo additional maneuvers to reduce its orbit before the lander, carrying the rover, separates from the propulsion module. 

The lander and rover have a mission life of one Lunar Day, equivalent to 14 Earth days, as they cannot withstand the extreme temperatures during lunar nights.

Why is Lunar Exploration so Important for India?

The Moon, being the closest cosmic body to Earth, offers an opportunity for space exploration and scientific discovery. It serves as a testbed for developing technologies essential for future deep-space missions.

ISRO recognizes the moon’s significance as a destination to advance our understanding of space and expand our capabilities in exploring the cosmos.

Is Chandrayaan 3 Launched in India?

Chandrayaan 3 is launched by India. The launch is carried out using the LVM3 vehicle from Sriharikota.

Is Chandrayaan-1 Still Working?

Chandrayaan-1, India’s first lunar mission, operated successfully until August 2009, after which communication was lost. It is no longer working.

Has India Landed on the Moon?

India had not landed a spacecraft on the Moon as of July 2023.

Which Country Successfully Landed on the Moon?

The countries that have successfully landed spacecraft on the Moon are the United States (through the Apollo missions), the Soviet Union (Luna program) and China (Chang’e program).

As Chandrayaan-3 soft landed on the moon at  6.04 pm  on  23 rd  August India became the  first country  to land a spacecraft in uncharted territory near the lunar south pole. India is only the fourth country  in history to complete a soft landing on the Moon after the United States, the Soviet Union and China.

Prime Minister Narendra Modi announced that the point where the Vikram   lander  touched down on the lunar surface would be named “Shiv Shakti”  and the crash site of the failed Chandrayaan-2 mission in 2019 as “ Tiranga point ”.

Chandrayaan-3

What were the mission objectives of Chandrayaan-3 mission?

The mission objectives of Chandrayaan-3 were as follows-

  • To demonstrate Safe and Soft Landing on Lunar Surface
  • To demonstrate Rover roving on the moon
  • To conduct in-situ scientific experiments

What are the components of Chandrayaan-3 Mission?

The Chandrayaan-3 Mission consists of two modules – The propulsion module (PM)  and the Lander module (LM) .

The main function  of Propulsion Module (PM) is to carry the lander Module (LM) from launch vehicle injection till final lunar 100 km circular polar orbit, where the LM separates from PM.

What are the different payloads used and what are their functions?

The different payloads used, and their functions are mentioned below-

What is the difference between Chandrayaan-3 and Chandrayaan-2?

Chandrayaan-3 has been designed incorporating the lessons from the crash landing of Chandrayaan-2 lander on the lunar surface. The difference between Chandrayaan-3 and Chandrayaan-2 are tabulated below:

Why did Chandrayaan-3 land on the near side of the moon?

Read More:  Why did Chandrayaan-3 land on the near side of the moon?

What discoveries have been made by Chandrayaan-3 so far?

Two major discoveries made by Chandrayaan-3 so far since it has landed on the lunar surface.

Presence of Sulphur and oxygen- Laser-Induced Breakdown Spectroscope (LIBS)  instrument onboard ‘Pragyan’  rover of Chandrayaan-3 has ‘unambiguously confirmed’ the presence of   sulphur  in the lunar surface near south pole. Other elements like Aluminum (Al), Calcium (Ca), Iron (Fe), Chromium (Cr), Titanium (Ti), Manganese (Mn), Silicon (Si), and Oxygen (O) are also detected.

Lunar temperature variation : Chandrayaan 3 has measured the soil temperature  of the moon and revealed some interesting findings. The temperature ranges from minus 10 degree celsius  to around 70 degree-celsius . While minus 10-degree was recorded at 80 mm under the ground 60-degree temperature was recorded at around 20 mm above the ground.

What is the significance of Chandrayaan-3 mission?

Scientific significance.

Shift in India’s space programme objectives:  The Chandrayaan-3 mission signals a shift of focus of India’s space programme. Earlier ISRO seemed focussed on utilitarian objectives  like enabling telecommunications, telemedicine and tele-education, broadcasting, or setting up remote sensing satellites. But with the Chandrayaan-3 space and planetary exploration  is becoming a priority for ISRO.

Boost to Future lunar space exploration:  The success of Chandrayaan-3 will boost the future lunar mission, like LUPEX  scheduled for 2024-25 and ISRO’s collaboration with JAXA, which will explore the permanently shaded region of the moon. ISRO will also get a boost for the International Lunar Research Station program which will be a better alternative to International space station for conducting space experiments.

Boost to Gaganyaan and Aditya L-1 missions : The launch vehicle used for Chandrayaan-3 mission is LVM-3 . It is the heaviest launch vehicle  of India and the successful launch of Chandrayaan –3 mission through this vehicle gives a boost to future Gaganyaan and Aditya L-1  missions which will launched by this LVM-3 rocket.

Boost to future ISRO’s Vision- ISRO can undertake several missions on the back of success of Chandrayaan-3 mission like launch of satellites powered by electric motors , quantum   communications , human space flight , reusable launch vehicles , planetary habitation and interplanetary communications.

Demonstration of India’s space technology prowess-  Demonstration of India’s capability in end to end soft landing and roving on the lunar surface.

Economic Significance

Boost to India’s push for “Space Industrialization”- The success of Chandrayaan-3 provides an opportunity for India to push for Space Industrialization .India can extract extra-terrestrial mineral resources and embark on deep space exploration.

Boost to the Indian space-tech ecosystem:  The successful launch of Chandrayaan-3 could bolster investor confidence  and attract more private investment  in space technology. Chandrayaan-3 mission’s success validates India’s space industry to emerge as a potential supplier for lunar programs undertaken by other countries . Make in India space program will also gain success. India’s space economy  can reach  $100 billion  by 2040.

Geo-political Significance

Enhancement of India’s role and position in the Artemis accord- India is now a member of the Artemis Accords  (the U.S.-led multilateral effort to place humans on the moon by 2025 and thereafter to expand human space exploration to the earth’s wider neighbourhood in the solar system). With the success of Chandrayaan-3 mission India has an opportunity to lead the other Artemis countries alongside the U.S.

Expansion of cooperation in outer space- While geo-political rivalry  is a reality, India’s success in space missions like Chandrayaan-3 provides India an opportunity to limit competition and expand cooperation in outer space. India can also  gain   military advantage  in space over their geopolitical rivals on Earth.

What are the challenges that Indian space sector faces despite Chandrayaan-3’s success?

Technological Challenges – While Chandrayaan  took nearly  six weeks  to get to the Moon, the failed Russian mission  Luna-25  took just one week to touch down (although it crashed). ISRO faces technological upgradation challenges like powerful launch vehicles with higher payload capacity and reach.

Budgetary Challenges- ISRO faces budget constraints  despite its successes in launching missions. There has been  an 8% decline  in budget allocations to ISRO in 2023-2024 with respect to 2022-2023. The funds allocated to the space sector are very less in comparison to other countries. The US spent 10 times  and China 6 times  more than India in the space sector in 2019-20.

Manpower Challenges- ISRO   faces manpower challenge due to the problem of Brain Drain and fewer students  pursuing advanced spaced space studies.

Government funded space missions- Some   critics have argued that such massive spending by the government alone  in these space missions curtail Indian government’s spending capability in social sectors like poverty alleviation, education and health which must be the priority for developing country like India.

Absence of a Clear Legislative Framework- The draft Space Activities bill which was introduced way back in 2017 but hasn’t been passed yet.

Lack of robust Dispute Settlement Mechanism- This discourages private investment  in the space sector. The void was seen in Antrix – Devas cancelled satellite deal . The Government of India owes nearly $1.2 billion to Devas Multimedia as per an order of a tribunal of the International Chamber of Commerce.

What should be the course of action for Indian Space sector to become a space superpower?

Despite successful missions like Chandrayaan-3 India’s share  in the total global space economy is just around 2%.  India needs to adopt a multipronged approach to become a space superpower in ‘Amrit Kaal’.

Push for privatization-  India must frame its space policy  to allow for greater private sector investment in field of space technology. India’s space programmes should be driven by commerce.

Passage of space Activities Bill- The passage of the Space Activities Bill  should also be done in order to give private players greater clarity and protection. This should involve proper consultation and discussions with the concerned stakeholders.

Setting up Space Dispute Tribunal- The plan to set up an independent tribunal  to adjudicate disputes among private space entities should be implemented promptly.

Enhanced International Collaboration- India must do more collaboration and research  with pioneer countries like the US & Russia who are already managing big constellations of satellites.

Conclusion-

Indian Space sector possesses huge untapped potential which can be realized with adequate policy measures by the government. This would boost the confidence of the private sector and deliver optimum results, thereby helping the country acquire the top spot in the global space industry.

Last updated on November 28, 2022 by ClearIAS Team

chandrayaan 3

What is  Chandrayaan-3 Mission? What are the features of Chandrayaan-3 Spacecraft? What is the information gathered by Chandrayaan-2 Mission? Why are we interested in studying the moon more? Read here to know more about this.

Chandrayaan 3 spacecraft is the 3rd lunar exploration expedition, outlined by the Indian Space Research Organisation (ISRO).

It will only consist of a rover and lander and will communicate with the earth via an orbiter from Chandrayaan 2.

Table of Contents

What is the Chandrayaan-3 Mission?

The Chandrayaan-3 mission is a continuation of Chandrayaan-2, which was launched in July 2019 and had the goal of putting a rover on the lunar South Pole.

The Vikram lander’s subsequent failure prompted the development of a different mission to show off the landing skills required for the 2024 lunar polar exploration mission that is being proposed in collaboration with Japan.

It will have a landing module and an orbiter. But unlike Chandrayaan-2, this orbiter won’t be equipped with a research payload.

Learn more from: ClearIAS Study Materials

Its only duties will be to launch the lander to the moon, monitor the landing from orbit, and maintain communication with the earth station.

This spacecraft was designed by ISRO to showcase India’s expertise in soft landings on stellar bodies.

According to ISRO, the Chandrayaan-3 mission will cost more than Rs 600 crores in total. In contrast, the Chandrayaan-2 mission cost a total of Rs 960 crores.

This expansive purpose includes integration, cognition, and a number of permutations. In addition, the spacecraft still needs to undergo a number of other thorough tests.

Features of Chandrayaan 3 Spacecraft

  • A rover and lander will be aboard Chandrayaan 3 as it launches into space. There won’t be any orbiters like Chandrayaan 2 in it.
  • India wants to look at the Moon’s surface, particularly in regions that haven’t seen sunlight in a few billion years. These darker regions of the lunar surface may contain ice and rich mineral deposits, according to scientists and astronomers.
  • Additionally, this exploration will try to examine the exosphere and subsurface as well as the surface.
  • This spacecraft’s rover will interact with Earth through an orbiter salvaged from Chandrayaan 2.
  • At a distance of 100 km from the lunar orbit, it will take pictures of the surface in order to analyse it.
  • The lander of ISRO’s Chandrayaan 3 will be powered by 4 throttle-able engines. In addition, it will be endowed with a Laser Doppler Velocimeter (LDV).

What was the Chandrayaan-2 Mission?

  • An orbiter, a lander, and a rover were made up of Chandrayaan-2, and were all outfitted with tools for studying the moon.
  • While the Lander and Rover modules were to be separated to make a soft landing on the moon’s surface, the Orbiter would observe the moon from a 100-km orbit.
  • The Lander and Rover modules were given the names Vikram and Pragyaan, respectively, by ISRO in honour of Vikram Sarabhai, the father of India’s space programme.
  • It was launched on the GSLV-Mk3, the nation’s most potent geosynchronous launch vehicle.
  • However, lander Vikram crashed-landed rather than making a controlled landing, which prevented rover Pragyaan from successfully exploring the moon’s surface.
  • The Orbiter, Lander, and Rover components of the Mission were assembled with the intention of investigating the Moon’s south pole.
  • It sought to explore the Moon’s exosphere, surface, and subsurface as a whole in a single mission, rather than just one particular location.

What happened to Chandrayaan-2?

  • The Chandrayaan-2 mission, which was aborted in 2019 after making a rough landing on the Moon’s dark side, is still operational thanks to its orbiter that is still in place.
  • In the last seconds, the lander and rover developed a problem, crashed, and were completely destroyed.
  • Chandrayaan 2’s main goal was to show off its capacity to soft-land on the moon’s surface and control a robotic rover there.
  • But in the past two years, the Chandrayaan-2 mission’s Orbiter and other instruments have gathered a wealth of new data that has expanded our understanding of the Moon and its surroundings.

Read about  Chandrayaan 2 Mission  in the linked article.

What is the information gathered?

Molecules of water are present on the moon:.

The mission has provided the most accurate data to date on the existence of H2O molecules on the Moon.

Presence of Minor elements:

Through remote sensing, the elements chromium, manganese, and sodium have all been discovered for the first time. The discovery may open up new avenues for research into planetary differentiation, nebular conditions, and lunar magmatic evolution.

Information about solar flares:

The first widespread observation of microflares outside the active area, according to ISRO, “has enormous consequences on the understanding of the mechanism driving heating of the solar corona,” a long-standing unanswered question.

Exploration of the areas that are always in shadow, as well as the craters and boulders that are hidden beneath the regolith, the loose deposit that makes up the top surface and extends down to a depth of 3 to 4 metres. This should enable scientists to pinpoint potential locations for future drilling and landing operations, including those involving people.

Why are we interested in studying the moon?

  • The Moon is the closest cosmic body at which space discovery can be attempted and documented.
  • It is also a promising test bed to demonstrate technologies required for deep-space missions.
  • The Moon provides the best linkage to Earth’s early history.
  • It offers an undisturbed historical record of the inner Solar system environment.

Why was the Lunar South Pole targeted for exploration?

  • The shadow-covered portion of the lunar surface at the South Pole is significantly bigger than at the North Pole, which makes it particularly interesting.
  • There might be a chance that regions nearby that are always in darkness contain water.
  • A fossil record of the early Solar System can also be found in cold trap craters near the South Pole.
  • The craters found at the southern pole are likewise of great interest to scientists. They think the mysterious fossil records of the early planetary system may be present in these cold traps.

What is GSLV-Mk 3?

  • Geosynchronous Satellite Launch Vehicle Mark-III was developed by the Indian Space Research Organisation (ISRO), is a three-stage vehicle, designed to launch communication satellites into geostationary orbit.
  • It has a mass of 640 tonnes that can accommodate up to 8,000 kg payload to Low Earth Orbit (LEO) and 4000 kg payload to GTO (Geo-Synchronous Transfer Orbit).

Importance of Exploring the Moon for Scientists

  • The Moon is the celestial body closest to Earth that can be used to test advanced space technology for lengthy space voyages.
  • It also serves as a promising cosmic body for the exploration and comprehension of extraterrestrial regions.
  • As a result, future scientists are motivated to pursue scientific research, and international cooperation is encouraged.
  • Additionally, it establishes a link between the early earth and the history of the solar system..

The COVID-19 pandemic and several phases of lockdown hindered multiple scientific projects of the Indian Space Research Organisation (ISRO). Along with Chandrayaan 3, the Gaganyaan, India’s 1st manned space mission has been delayed. Nevertheless, the spacecraft is now ready to travel to the Moon at the end of 2022.

CHANDRAYAAN 3

The success of the Chandrayaan 3 mission is a significant milestone as it not only makes India the fourth nation to successfully soft land a spacecraft on the moon but also the first to land on the south pole, which has been unexplored until now.

But why is there a larger interest in the moon’s South Pole?

Due to the moon’s tilt, only the elevated peaks at the lunar south pole are lit by the sun, and the low-lying areas in the region are permanently shrouded in shadow. The temperatures in these permanently shadowed regions (PSRs) can drop extremely low, implying that any water molecule that enters the area is immediately frozen, making it an ideal spot to maintain water ice. In 2008, India’s previous lunar orbiter, Chandrayaan 1, confirmed water’s presence in icy craters on the south pole.

The findings of Chandrayaan 3 can have enormous implications for future human missions by harvesting water as fuel, breathable oxygen, or drinking water. It opens up a possibility for a staging mission (To lighten the vehicle’s weight to achieve orbital velocity; most launchers discard a portion of the vehicle in a process called staging) to Mars launched from the moon someday, which is an incredibly exciting prospect for future space exploration!

The Chandrayaan 3 began its two-week mission (1 lunar day) after it landed on 23rd August 2023 to explore the south pole of the Moon. It consists of three main components – the  Propulsion Module (PM) , the  Lander Module  and the  Rover .

  • A propulsion module (PM) carries the lander module to the final lunar 10km circular polar orbit and launches it and has a scientific payload whose objective is the future discoveries of exo-planets for habitability.
  • The Lander module’s function is to soft land on the lunar surface and deploy the rover. The lander payload aims to measure the near-surface plasma density, thermal properties, and seismicity around the landing site.
  • The rover payloads (a payload is a scientific or technological instrument carried on board a satellite for a specific purpose) aim to determine the chemical composition and infer the mineralogical composition of the lunar surface in the region.

This is the first of many missions the Indian Space Research Organisation (ISRO) has planned for space exploration and resource mining. Aditiya L1 was also recently launched, which will function as a space weather station. This mission promises to offer previously unknown insights about the moon that will help advance space exploration in the future.

Introduction and Background

Insight had the opportunity to interview Brajpal Singh, a second-year MTech student and Naresh Sanke, a first-year MTech student at IITB who were directly involved in the glorious Chandrayaan 3 mission. Brajpal and Naresh completed their BTech in Electronics and Avionics, respectively, from IIST (Indian Institute of Space Science and Technology).

In Naresh’s words,  “I was always interested in mathematics and physics and deeply loved engineering. I remember following the journey of Chandrayaan 1 in awe, on the news and wondering how something incredible like that happened.”  Brajpal, too, had always aspired to be a scientist and was particularly fascinated by the mysteries surrounding extraterrestrial life.

Before joining IITB, they worked at ISRO and contributed towards this celebrated mission. Brajpal spent three years working on the electronics part of the SHAPE payload, whose purpose is to study Earth’s spectral and polarimetric measurements from lunar orbit. This will help the scientists to mimic the observation of a far-away exoplanet. Naresh, on the other hand, worked on testing the RAMBHA payload, which measures different parameters of the plasma above the moon’s surface, which he had also done for Chandrayaan 2. Although he has worked on the Chandrayaan 2 and 3 missions, he is closest to the Aditya L1 mission as he has devoted the majority of his time at ISRO working on it.

Journey and Experience at ISRO

Brajpal was placed in ISRO’s URO satellite center in Bangalore in August 2011. In 2019, he was placed in the Space Astronomy group to make an observational payload, the SHAPE (Spectro-polarimetry of HAbitable Planet Earth) payload for the Chandrayaan 3 mission. Talking about his work on Chandrayaan 3, he said,  “Making it (Chandrayaan 3) was challenging, especially after previous successful space missions, because the pressure of doing something new was high, and you never repeat a machine at ISRO”.

Naresh joined ISRO in September of 2018. He was placed in the Thiruvananthapuram centre, where he trained for three months after which he joined the electronics design division. Reminiscing about his time at ISRO, he says, “One’s experience at ISRO depends largely on where they’re posted. There are places where every day is a challenge and others where some days might be uninteresting. Nevertheless, my deliverables aligned with my Avionics degree, unlike some of my colleagues who were placed in entirely unrelated disciplines.”

When asked about the team culture at ISRO, both scientists agreed that the environment at ISRO is excellent.  “There is no strict hierarchy, and juniors are always encouraged to question and counter their seniors. Everyone is open to listening to new ideas, and they have always felt free to express their views.” , says Brajpal.

An example of such an interaction is the SHAPE payload itself on which Brajpal worked. One of his colleagues, a junior scientist at ISRO, proposed the idea of the payload just three years before the mission deadline which was accepted wholeheartedly. A team with several scientists with different experiences was assembled, and the junior scientist who had devised the idea took the lead.

When asked about the freedom to pursue personal ideas and the support available for the same, Brajpal commented,  “At ISRO, scientists also have the liberty to work on new ideas and pursue them independently in their extra hours. There is never a block in our mind about our idea not being executed. We share our work and responsibilities, and that’s how we achieve success.”

Contribution to Chandrayaan 3

ndtsp

The Space Astronomy group is responsible for making payloads that make space observations, very similar to the Hubble Telescope and the JWST (James Webb Space Telescope).

The Propulsion module of Chandrayaan 3 has only one scientific payload, and Brajpal worked on the electronics subsystem for it. The Chandrayaan 3 original mission plan did not involve a payload; its only job was to take the rover to the moon. However, Brajpal and his peers did not want to let go of the unique opportunity of being on the Moon. They decided to use this opportunity to make a payload to observe Earth from the vantage point of the Moon. The decision to incorporate the SHAPE payload into the mission plan was taken way after the work on the Chandrayaan 3 mission started;  “We kind of pushed ourselves in the middle (of the mission)” , said Brajpal.

The idea of the SHAPE payload was developed. It is an experimental payload onboard the Chandrayaan-3 Mission to study Earth’s spectro-polarimetric signatures in the near-infrared (NIR) wavelength range (1.0 – 1.7 μm). The purpose of the payload is to observe our planet Earth from the moon and help in future discoveries of smaller planets in reflected light, allowing us to probe into various exo-planets that qualify for habitability. The SHAPE payload demonstrates new technology for both sensing purposes and scientific interest.

The work on the payload started when COVID-19 was at its peak, in the form of endless online discussions where the team finally arrived at the final design. As COVID subsided and the lockdown lifted, it was time to turn the design into reality. The team’s timely completion of the task at hand became crucial at that stage because any delay would have resulted in its exclusion since the mission could not be delayed.

“Three years is very little time to work on a payload that will be a part of this big mission” , says Brajpal. To put it into perspective, the Hubble telescope was launched 20 years after its planning, and the JWST after 30 years!

ndtsp

Naresh was also involved in the Chandrayaan 2 mission, which he had joined in its final leg of completion to conduct the tests for payload qualifications as a part of the qualification team. For Chandrayaan 3, his group was supposed to make a replica of the previous payload, called the RAMBHA-LP payload – The Radio Anatomy of Moon Bound Hypersensitive ionosphere and Atmosphere – Langmuir Probe, named after American chemist and physicist Irving Langmuir, who was awarded the Nobel Prize in Chemistry. The Langmuir probe is a device used for characterising a plasma.

This mission holds immense scientific importance. While discussing the significance of Chandrayaan 3, Naresh highlighted that  even though India made the mission possible, other member nations at BRICS were excited and rooting for its landing, making it a global achievement.  It was of monumental significance in the history of Science, since it was the first time that the southern region of the moon was being explored, and new data was going to be recorded. The findings would have the potential to open up the door for endless future possibilities.

Experience of working on Space Missions:

When asked about what was something that they loved most about working on the mission, Brajpal said,  “I like the interdisciplinary nature of the work the most. Even though I come from an electrical background, I cannot keep myself limited to it; I need to think from mechanical and structural perspectives and consider their limitations when working on the assembly. For example, the PCB (Printed Circuit Board) risks breaking in a harsh space environment. Therefore, the electronics must be combined with adequate mechanical, structural, and thermal knowledge.”  He firmly believes that interdisciplinary expertise and gaining a broader perspective are essential for a person if they aim to achieve something big in their field of interest.

Naresh also insisted that the work is highly interdisciplinary. He stated,  “I had to test the sensor and electronics part for the Aditya L1 payload which aims to measure solar winds. The team responsible for this testing consisted of the electrical, mechanical science, and integration subsystems. The subsystems gather in review meetings, and each sub-system learns from the other in a collaborative environment. It also challenges them to integrate and solve the constraints caused by other subsystems into their mechanisms.”

Motivation and Challenges:

“Most space science missions run on for years, but what keeps us scientists motivated in such long and daunting time frames is that everyone loves challenges at ISRO” , says Brajpal when asked about how the scientific community at ISRO keeps itself motivated to work on missions that yield results after years.  “They solve problems one at a time, and at the end of three years, they realize they’ve managed to make an entire satellite ready to go to the moon!”

While talking about his work, Brajpal passionately mentioned,  “Although the work is rigorous and challenging, it feels very rewarding, and I will never get tired of it. I remember every problem put forth to me during the mission. I would work on them all night and often find solutions early in the morning after hours of struggle.”

While speaking about his challenges, Naresh told us about the technical challenges that arise while learning and doing something new, about working over the weekends to meet deadlines, and personal challenges resulting from staying away from home. However, he was able to survive through it all because, as put in his words,  “My team helped me push through it all. It is the act of learning something new and fascinating every day that motivates them to overcome challenges.”

Space missions like these require a lot of precision, and tiny errors can add up to a considerable error, which could be catastrophic. In the context of Chandrayaan 3, Naresh said,  “So many things could have gone wrong, and it still landed! In the last stage of the landing, it stopped, hovered over a spot, figured out it was not an optimum spot to land, and landed elsewhere. That design getting validated felt amazing!”

It is a proud moment for the nation, and speaking about pride, Naresh commented that he feels happy about his work and contribution at ISRO. However, for him, he says,  “Satisfaction comes from an outer perspective, like when my brother told me how proud he is of our work.”

Future Missions:

In the future, Brajpal wishes to work on missions like Gaganyaan, which is a part of the broader Indian spacefaring ambition that extends to potential human missions to the Moon and Mars. He would love to be a part of any space exploration mission that ISRO does. The question of whether or not we are alone in this universe excites him the most about his work, and he holds a strong interest in participating in any future missions aimed at exploring the existence and mysteries of extraterrestrial life.

Parallel to Aditya L1, Naresh also worked on the Venus Orbiter Mission, set to launch in December 2024. In his previous missions, he worked mainly on the payload testing mechanisms. However, in the Venus mission, he helped design the payload from scratch. After finishing some preliminary designs, he came to IITB for his Master’s and was relieved from ISRO for two years. Like his peers, he gets utterly fascinated by how the universe works, which inspires and motivates him to continue doing what he does.

A word for Space enthusiasts:

When asked what he would like to tell the students who wish to pursue a career in space science, Brajpal commented,  “Students often perceive space science as something that is all glittery and glamorous when they think of it as a field they want to pursue their career in. Movies glamorise it as well and don’t show the hard work, grind and perseverance behind it. Missions such as Chandrayaan are full of unexpected challenges at every single turn. The motivation and craze to make an idea work and the curiosity and interest to figure out why something is not working are needed in every individual who is a part of the mission. Work can get challenging sometimes, and as technology advances, one needs to constantly upgrade their skills and knowledge to keep up with the demand of the times.”

  Syllabus: Science and Technology: Space

  Context: Chandrayaan-3 is India’s upcoming lunar mission, which aims to be the world’s first mission to soft-land near the lunar south pole.

What is Chandrayaan-3 Mission?

Chandrayaan-3 is  India’s third moon mission and is a follow-up of Chandrayaan-2 (2019) which aimed to land a rover on the lunar South Pole . The Mission will have three major modules- the

  • Propulsion module ( will carry the lander and rover configuration till 100 km lunar orbit)
  • Lander module (capability to soft land and deploy Rover)
  • Rover (will carry out in-situ chemical analysis of the lunar surface)

Challenges of landing on the South Pole:

Previous spacecraft have mostly landed near the equatorial region of the Moon, a few degrees latitude north or south of the lunar equator. Landing near the equator is easier and safer due to the hospitable terrain , smooth surface, absence of steep slopes, and ample sunlight for solar-powered instruments.

The lunar south pole, on the other hand, presents a challenging terrain with extreme temperatures and areas that are in permanent shadow, receiving no sunlight .

Why ISRO wants to explore the Moon’s south pole?

  • Exploring and confirming the presence of water is essential for future human missions and the potential utilization of lunar resources.
  • Scientific Discoveries: The extreme environment and the presence of permanently shadowed regions provide a preserved record of the Moon’s history and the early Solar System .
  • By studying the lunar south pole, scientists can gain insights into the materials and conditions that existed during the formation of the Earth-Moon system.
  • Global Collaborations : ISRO-NASA successfully confirmed the presence of water from the data taken by Chandrayaan-1. Indo-Japan collaboration, LUPEX aims to send a lander and rover to the Moon’s south pole around 2024.
  • Technological Advancements : By undertaking missions to this region, ISRO can develop and demonstrate innovative technologies for soft landing, navigation, resource utilization, and long-duration operations that can be applied in future space missions.

Comparision of  Chandrayaan-1, 2 and 3

About LVM3:

Launch Vehicle Mark 3 (LVM3) (previously known as GSLV-MK III) is a  three-stage launch vehicle  consisting of two solid propellants S200 strap-ons on its sides and a core stage comprising L110 liquid stage and C25 cryogenic stage.

Thirdly, now there will be more progress in space technology in our country.

Fourthly, the success of Chandrayaan 3 is also very important for the youth of our country.

The history of Chandrayaan:

The Indian Space Research Organization sent its first spacecraft to the Moon in 2008. This car is considered to be India’s first driverless vehicle. This vehicle was sent to the moon with the help of a rocket. The duration of Chandrayaan 1 was 10 days and 6 months. The purpose of this mission was to detect water and helium fractions on the Moon. India made another history when it decided to send Chandrayaan 2 to the moon. Indian scientists did not use any foreign technology to build the entire Chandrayaan 2. Chandrayaan 2 had an orbiter, a rover and a lander. Chandrayaan 2 was launched by ISRO on 22 July 2019 from the Sriharikota range. Under this mission, Chandrayaan 2 travelled 47 days in space. But before this mission could be completed, ISRO lost contact with the lander Vikram. In fact, Vikram’s lander crashed after hitting the lunar surface. And finally, the Chandrayaan-2 mission was not successful.

Conclusion:

Prime Minister Narendra Modi named the Vikram rocket landing site “Shiv Shakti” point. As the Vikram lander landed on the moon on August 23, it was declared as “National Space Day”. The younger generation will be inspired to pursue science, technology, engineering, and mathematics careers by this mission. All countrymen are proud of this success of the country.

Chandrayaan-3 touched down like a feather, didn’t kick up much dust

I ndia’s Chandrayaan-3 mission made history on Aug 23, 2023 with an incredibly gentle landing. Despite the powerful engines required for descent, the lander kicked up minimal lunar dust, a new paper presented by Isro scientists at last month’s Lunar and Planetary Science Conference in Texas reveals.

The study was carried out by Amitabh, K Suresh, Kannan V Iyer, Ajay K Prashar, Shweta Verma and Abdullah Suhail from Isro’s Space Applications Centre. That Chandrayaan-3, which made so much noise on Earth, barely kicked up any dust on Moon has significant implications for future lunar exploration missions.

Art Of Soft Landings

Landing on Moon’s surface is no easy task. Spacecraft must fire powerful engines to slow down and descend in a controlled manner. However, this engine exhaust can interact with the lunar surface, kicking up plumes of dust and debris, and spreading it around the landing site.

Previous lunar landing missions, such as the famous Apollo missions and China’s Chang’e-3, raised dust plumes of up to 60m (nearly 200 feet) height. Such massive dust clouds can potentially damage sensitive equipment, obscure the view of the landing site, and even contaminate scientific samples collected by rovers or astronauts.

Minimal Dust Disturbance

Vikram, the Chandrayaan-3 lander, however raised a dust plume of only 8.7-12m (28-39 feet), images captured by cameras on the lander, orbiter (from Chandrayaan-2), and rover Pragyan reveal. Furthermore, the area affected by the dust spread was relatively small, covering only about 145 sq-m (around 1,560 sq feet), with a spread of roughly 17m (56 feet) in one direction and 14m (46 feet) in another.

The soft touchdown suggests the lander’s design and engine configuration were optimised for minimal interaction between the engine plume and the lunar surface. Chandrayaan-3’s feat is likely due to a combination of factors, such as the lander’s lightweight design, precise control of the engine thrust during descent, and the specific properties of the lunar soil at the landing site.

30km Of Controlled Descent

Vikram landed on the lunar southern hemisphere between craters “Manzinus-U” and “Boguslawsky-M” at a point later named “Shiv Shakti” by Prime Minister Narendra Modi. Its lander imager (LI) captured and transmitted a total of 835 images to Earth in near-real-time mode, providing crucial insights into the landing process and the lunar surface environment.

While landing, all four engines of Chandrayaan-3 started firing at an altitude of nearly 30km for deceleration and worked until the lander’s first hovering at an altitude of 800m. After that, only two diagonal engines were kept on until touchdown.

When the four sensors in the lander’s footpad indicated touchdown, in combination with an accelerometer reading of zero, the engines were shut down within 30 milliseconds, ensuring a gentle and controlled landing on the lunar surface.

Key To Design Improvement

The minimal disturbance of lunar dust has significant implications for future lunar exploration missions. It demonstrates the possibility of landing spacecraft on Moon with minimal environmental impact, preserving the pristine nature of the lunar surface for scientific study and reducing the risk of damage to sensitive equipment.

Additionally, understanding the mechanisms behind this low dust disturbance could help engineers design even more efficient and environmentally-conscious landers and rovers for future missions.
