Chandrayaan-3 Mission is the second attempt of the Indian Space Research Organisation after the Chandrayaan-2 to demonstrate the capability of India in safe landing and roving on the lunar surface. The Lander Module of Chandrayaan-3 carrying the Lander, Vikram and Rover, Pragyan,  made the historic soft landing on the surface of the Lunar South Pole on August 23, 2023 . Thus, India became the first nation to soft-land on the surface of the Lunar south pole and overall the fourth to do a soft landing anywhere on the Earth’s natural satellite. Indian Space Research Organisation launched the Chandrayaan-3 Mission by using the Geosynchronous Satellite Launch Vehicle Mark III (LVM3) on 14th July 2023 from Sriharikota.

With the objective to demonstrate the ability to soft landing and roving as well as to carry out experiments on the lunar surface, the Chandrayaan 3 Mission aims to strengthen India's prowess in space discovery and innovation. Continuing the success of its predecessors (Chandrayaan-1 and Chandrayaan-2), the Mission has brought India into the exclusive elite space club.

What is the Chandrayaan 3 Mission?

The Chandrayaan 3 Mission was launched using the LVM3 rocket system. LVM3 is the new launch vehicle of ISRO with the capability to place the modules into the GTO (Geosynchronous Transfer Orbit) in a cost-effective manner. It is a three-stage launch vehicle with two solid strap stages and one core liquid stage. The Launcher, LVM3 M4, placed the integrated Modules in an Elliptic Parking Orbit of size approx. 170 x 36500 km (a GTO).

Objectives of Chandrayaan 3 Mission

One of the many goals of the Mission is to look for water ice that could support future human life on the Moon and also for supplying propellants for spacecraft in future interplanetary missions. The objectives of the Chandrayaan-3 mission are:

  • Safe and Soft Landing on the Lunar Surface by the Lander
  • Roving on the Moon by the Rover
  • In-situ scientific experiments by the Rover

LVM3 Rocket

The Chandrayaan-3 Mission consists of two modules - The propulsion module (PM) and the Lander module (LM). The total mass of both the modules is 3900 kg (Propulsion Module-2148 kg, and Lander Module-1752 kg, including Rover-26 kg).

Parts of the Chandrayaan 3 Mission

Propulsion Module

The propulsion module carried the lander and rover configuration till the 100 km lunar orbit. Other than carrying the Lander Module, it also has a scientific payload called Spectro-polarimetry of Habitable Planet Earth (SHAPE).

  • The SHAPE payload will conduct novel spectro-polarimetric studies of Earth from lunar orbit. It will look for smaller planets that could be habitable in the reflected light.

Lander Module

Chandrayaan 3 lander module

The Lander Module consists of a Lander (Vikram) and a Rover (Pragyan). The Lander Module made the soft landing using the Automatic Landing Sequence (ALS), where the Lander started its engine (thrusters) and maneuvered the speed and direction of the Module as well as the position of the landing site.

After the historic touchdown, the Rover inside it ramped down on the lunar surface to carry out in-situ chemical analysis of the lunar surface during its mission life.

  • The total lifespan of the Mission (Lander and Rover) is lunar day (14 Earth days).
  • Both the Lander and the Rover have scientific payloads to carry out experiments on the lunar surface.
  • The objectives of scientific payloads planned on the Chandrayaan-3 Lander Module and Rover are provided below:
  • Launched: July 14, 2023
  • Inserted into Lunar Orbit: August 05
  • Separation of the Lander Module from the Propulsion Module: August 17
  • Deboosting is the slowing down of the spacecraft in an orbit where the Perilune (closest point to the Moon) is 30 km, and the farthest point (the Apolune) is 100 km from the landing site in the South Polar Region.
  • It is required for the proper landing as the speed needed to land is much less than the lander.
  • Second Deboosting on August 20
  • The targeted site on the Moon was around 70 degrees South near the Southern pole of the Moon.
  • If the Lander had missed the target of the commencement of the soft landing, It would have to wait for 1 month.
  • It landed at around 69.36°S and 32.34°E (between Manzinus C and Simpelius N craters).
  • Rover started its exploration on August 24

What differentiates Chandrayaan 3 from Chandrayaan 2?

Chandrayaan-2 failed in the final phase of its mission in 2019 because it could not achieve a soft landing. The main issue for the crash was that the five thrusters on the lander developed a higher velocity than expected. Also, the lander had to take pictures to fix the landing site. All of this made the accumulated errors. Learning from previous experiences, the ISRO had incorporated some advancements to achieve success this time, which are as follows:

“Failure-based design” instead of the "Success-based design":

  • The failure-based design means that if everything, including sensors and electronics, had failed, Vikram would still have made the soft landing.
  •  This was done by identifying and rectifying all the probable scenarios that could go wrong.
  • These included failure of electronics, engine failure, unable to reach the landing spot, sensor failure, algorithm failure, velocity higher than required, etc.

Increase in the landing area:

  • The target area of Chandrayaan-3 was kept at 4km x 2.4km area instead of 500m x 500m targeted by Chandrayaan-2 so that the Lander had more options to choose the best target site on its own.

More fuel to Lander:

  • It was kept to facilitate the Lander to travel longer distances to the landing site and, if needed, to the alternate landing site.

Help from Chandrayaan-2 orbiter:

  • The Chandrayaan-3 mission does not carry an orbiter; it is using the high-resolution images from the Chandrayaan-2 orbiter.

More robust integrated craft:

  • The weight of the payload of Chandrayaan-3 had been kept more than the Chandrayaan-2, with the Lander having most of the extra weight for successful landing.
  • The number of thrusters had decreased from five to four with no central thrusters.
  • The legs of the Lander were made sturdier to ensure that they could land even at a higher velocity.
  • Use of additional solar panels to ensure power generation after a soft landing regardless of the weather on the Moon.

Chandrayaan-2 Vs Chandrayaan-3

Chandrayaan-3 vs Luna-25

Luna-25, Russia's first lunar mission since 1976, has recently crashed in an attempt to get into the landing orbit. It was targeted to land at the South Pole of the Moon, of particular interest to researchers believing that the polar craters might contain frozen water in their rocks. There are some differences between the Chandrayaan-3 and the Luna-25, which are as follows:

India has become the first nation to reach the south pole of the Moon after its Chandrayaan-3 probe successfully landed as planned.

The landing comes just days after Russia’s Luna-25, destined for the same region, crashed on the lunar surface.

India's Prime Minister Narendra Modi congratulated scientists at the Indian Space Research Organisation (ISRO) via a video conference and said the historic mission will help all countries, including those in the global south, "to aspire for the Moon".

The rover Pragyan will shortly roll out of the lander Vikram , ISRO sources said.

Chandrayaan-3 will perform a raft of experiments, including a spectrometer analysis of the mineral and chemical composition of the Moon's surface, returning valuable data on the properties of lunar soil and rocks. It hopes to confirm the presence of water ice in the region, which could supply oxygen, fuel, and drinking water for future space exploration.

Mylswamy Annadurai, director of Chadrayaan-1, India's first Moon mission, told Nature India that the soft landing of Chandrayaan-3 mission will open many opportunities. “This will consolidate India’s position in the future international lunar missions, including that of Artemis .”

Scott Hubbard, former NASA Ames Center director, now with Stanford University, said safely landing a spacecraft on another world is an outstanding scientific and engineering achievement. “With the successful landing of Chandrayaan-3, India has joined a very exclusive club.”

The journey

The voyage by Indian Space Research Organisation (ISRO) started on July 14. Launch vehicle LVM-3 sent Chandrayaan-3 on a 384,000km journey from the Satish Dhawan Space Centre in Sriharikota on India’s southeast coast.

Chandrayaan-3 orbited Earth several times to gain speed before embarking on its month-long lunar trajectory. Three successive orbit reduction manoeuvres on August 6, 9, and 14 moved the spacecraft closer to the Moon. The final manoeuvre on August 16 placed Chandrayaan-3 into an orbit of 153km x 163km, inching it closer to its final landing.

On August 17, the lander separated from the propulsion module on August 17, and slowed to place itself in an orbit where the Perilune (orbit’s closest point to the Moon) was 30 km and Apolune (farthest point from the Moon) was 100 km.

India’s first Moon mission had discovered water molecules on the lunar surface. The second mission Chandrayaan-2 in 2019 crashed during the crucial touchdown.

The science

Chandrayaan-3 comprises an Indian-built lander module (LM), propulsion module (PM) and a rover. The mission goal is to develop and demonstrate new technologies for inter-planetary missions.

The Vikram lander carries an instrument called Chandra’s Surface Thermophysical Experiment (ChaSTE) to measure surface thermal properties, an Instrument for Lunar Seismic Activity (ILSA) to measure seismicity around the landing site, the Radio Anatomy of Moon Bound Hypersensitive ionosphere and Atmosphere (RAMBHA) to study the gas and plasma environment, and a passive laser retroreflector array provided by NASA for lunar ranging studies.

The rover Pragyan (Sanskrit for ‘wisdom’) is to carry out a chemical analysis of the lunar surface in situ as it moves about in the highlands near the Moon’s south pole. The six-wheeled rover will conduct experiments here for one lunar day, equivalent to 14 Earth days.

The rover has two instruments to study the local surface elemental composition — an Alpha Particle X ray Spectrometer(APXS) and a Laser Induced Breakdown Spectroscope(LIBS).

Amitabha Ghosh, a contributor to NASA’s Rover mission to Mars, and a part of the Mars Pathfinder mission team, told Nature India that while the feat will be remembered as a “golden day in the history of Indian space exploration,” scientists were keenly “looking forward to the science investigation that the rover will embark on in the coming days and also the new knowledge about the south pole.”

After Chandrayaan-2’s failure, the focus was on the crucial landing, which entailed extensive simulations. The lander was equipped with stronger landing legs, more propellant and improved sensors. The software was changed and the landing area was expanded.

There have been several challenges in building the two instruments that are being carried by Pragyan .

“The main challenge was to indigenously design the electronics such that the excellent energy resolution provided by the state-of-the-art Silicon Drift Detector (SDD), the X-ray detector used in APXS, is not degraded,” principal investigator Santosh Vadawale, an astrophysicist at the Physical Research Laboratory, Ahmedabad, told Nature India.

APXS uses Cm-244 radioactive sources to excite elements on the lunar surface. “Obtaining these sources and handling them throughout the development cycle and various phases of testing was a major challenge because of the radiation safety aspects,” said Vadawale.

  • 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.

Chandrayaan-1 was launched in 2008 and lasted till 2009 after communications to it were lost. The mission, among other things, tested a crash landing on the lunar surface. Chandrayaan-2 , launched in 2019 attempted a soft landing on the moon but failed. The third mission, Chandrayaan-3 took into account the drawbacks and lessons learnt from the second mission and successfully achieved soft landing.

Objectives of Chandrayaan 3 Mission

  • To demonstrate a safe and soft landing on the lunar surface
  • To demonstrate rover roving on the moon
  • To conduct in-situ scientific experiments

Chandrayaan III Features

Chandrayaan 3 Payloads

Chandrayaan 3 mission’s lander is named Vikram and the rover Pragyan, like those of the second mission.

  • The mission consists of a lander module, a propulsion module, and a rover.
  • SHAPE has the objective of exploring exo-planets for habitability by studying reflected light. 
  • Chandra’s Surface Thermophysical Experiment (ChaSTE) to measure the thermal conductivity and temperature
  • Instrument for Lunar Seismic Activity (ILSA) for measuring the seismicity around the landing site
  • Langmuir Probe (LP) to estimate the plasma density and its variations
  • A passive Laser Retroreflector Array from NASA for lunar laser ranging studies
  • Alpha Particle X-ray Spectrometer (APXS)
  • Laser Induced Breakdown Spectroscope (LIBS)
  • The advanced technologies present in the payloads help in conducting scientific experiments on the moon.
  • The mission’s life is one lunar day or 14 earth days.
  • The budget of the Chandrayaan-3 mission is Rs 615 crore.

Chandrayaan 3 Mission Timeline

  • Chandrayaan-3 mission took off on July 14, 2023 from the Satish Dhawan Space Centre (SDSC) in Sriharikota, A.P.
  • On August 5, the mission entered the lunar orbit.
  • On August 17, the lander module separated from the propulsion module.
  • Deboosting is the slowing down of the spacecraft in an orbit where the Perilune (closest point to the Moon) is 30 km, and the farthest point (the Apolune) is 100 km from the landing site. 
  • This process is necessary for the proper landing of the spacecraft.
  • On August 23, the lander landed at around 69.36°S and 32.34°E (between Manzinus C and Simpelius N craters) on the south pole of the moon.
  • On August 24, the rover Pragyan started its exploration.
  • Laser-Induced Breakdown Spectroscopy (LIBS) is a scientific method using intense laser pulses to analyse material composition.

How is Chandrayaan 3 Different from Chandrayaan 2?

Many changes and improvements were made to the third lunar mission taking into account the lessons learnt from the failed soft landing mission of Chandrayaan-II. Major changes included strengthening the legs of the lander, enhancing fuel reserves and expanding the landing site. Previously, the Vikram lander of Chandrayaan-2 had lost control and communication during descent, which caused it to crash on the moon’s surface. Chandrayaan 3 focused on a failure-based design approach to foresee and prevent potential mishaps.

  • The landing area was expanded giving flexibility to soft-land safely within a larger designated region on the surface of the moon.
  • Vikram was equipped with more fuel enabling it to travel more towards the landing site.
  • Chandrayaan 2 had only two solar panels while Chandrayaan-3 has four.
  • The lander’s speed was continuously monitored by an instrument called Laser Doppler Velocimeter onboard the mission that sent laser beams to the lunar surface to calculate the Lander’s speed.

Significance of Lunar South Pole

Previous lunar missions have focused on the equatorial region of the moon owing to its favourable terrain. The south pole region is more challenging compared to the equatorial region. The lack of enough sunlight and extreme cold conditions (up to -230 degrees C) lead to difficulties in instrument operation and sustainability. The polar regions may contain water according to scientists. Also, experts think that the craters in these regions contain fossil records of the early planetary system.

Chandrayaan-3

India has started its third Moon mission, with the goal of becoming the first to land near the Moon’s little-explored south pole. The Chandrayaan-3 spacecraft, which included an orbiter, lander, and rover, lifted out from the Sriharikota space center at 14:35 on Friday (09:05 GMT).

The Chandrayaan-3 mission is the third in the Chandrayaan program, a series of lunar exploration missions created by the Indian Space Research Organization (ISRO). The mission, which will be launched on July 14, 2023, will comprise of a lunar lander named Vikram and a lunar rover named Pragyan, both of which were launched aboard Chandrayaan-2 in 2019.

On July 14, 2023, Chandrayaan-3 was launched from Satish Dhawan Space Centre. On 5 August, the spacecraft entered lunar orbit, and the lander landed near the lunar south pole on 23 August at 18:03 IST (12:33 UTC), making India the fourth country to safely land on the Moon and the first to do so near the lunar south pole. The lander hopped and relocated itself 30-40 cm (12-16 in) from its landing spot on September 3.

ISRO’s mission objectives for the Chandrayaan-3 mission are:

  • Engineering and implementing a lander to land safely and softly on the surface of the Moon.
  • Observing and demonstrating the rover’s driving capabilities on the Moon.
  • Conducting and observing experiments on the materials available on the lunar surface to better understand the composition of the Moon.

After completing all of its missions, the rover was placed to sleep on September 3. According to ISRO, its batteries were charged and the receiver was left on in preparation for the upcoming lunar night. “The rover’s payloads are turned off and the data it collected has been transmitted to Earth via the lander”, added the announcement. The lander and rover aboard Chandrayaan-3 were only expected to operate for one lunar daylight period, or 14 Earth days, and the on-board electronics were not built to resist the Moon’s overnight temperatures of −120 °C (−184 °F). The lander and rover did not answer to their wake-up calls on September 22nd, and by September 28th, neither had responded, lowering hopes for future surface operations.

On September 3, Vikram activated its engines for a brief ‘hop’ on the lunar surface, climbing 40 cm (16 in) and translating a similar distance laterally across the surface. The experiment exhibited skills that could be utilized in future sample return missions. The equipment and rover deployment ramp were withdrawn and redeployed following the hop.

Mission life

  • Propulsion module: Carries lander and rover to 100-by-100-kilometre (62 mi × 62 mi) orbit, with operation of experimental payload for up to six months.
  • Lander module: one lunar daylight period (14 Earth days).
  • Rover module: one lunar daylight period (14 Earth days).

Chandrayaan-3 facts for kids

Chandrayaan-3 ( transl.  Moon-craft , ) is the third Indian lunar exploration mission under the Indian Space Research Organisation's (ISRO) Chandrayaan programme . It consists of a lander named Vikram and a rover named Pragyan , similar to those of the Chandrayaan-2 mission. The propulsion module carried the lander and rover configuration to lunar orbit in preparation for a powered descent by the lander.

Chandrayaan-3 was launched on 14 July 2023. The lander and rover landed near the lunar south pole region on 23 August 2023 at 18:02 IST , making India the first country to successfully land a spacecraft near the lunar south pole and the fourth country to soft-land on the Moon .

Mission life

Temperature variation, detection of sulphur, lunar water, domestic reactions.

On 22 July 2019, ISRO launched Chandrayaan-2 on board a Launch Vehicle Mark-3 (LVM3) launch vehicle consisting of an orbiter, a lander and a rover . The lander was scheduled to touch down on the lunar surface in September 2019 to deploy the Pragyan rover . The lander ultimately crashed when it deviated from its intended trajectory while attempting to land.

Following Chandrayaan-2, Chandrayaan-3 and further lunar missions were proposed.

The European Space Tracking network (ESTRACK), operated by the European Space Agency (ESA), is supporting the mission. Under a new cross-support arrangement, ESA tracking support could be provided for upcoming ISRO missions such as those of India's first human spaceflight programme, Gaganyaan, and the Aditya-L1 solar research mission. In return, future ESA missions will receive similar support from ISRO's own tracking stations.

ISRO set the following mission objectives for the Chandrayaan-3 mission:

  • Getting a lander to land safely and softly on the surface of the Moon.
  • Observing and demonstrating the rover's driving capabilities on the Moon.
  • Conducting and observing experiments on the materials available on the lunar surface to better understand the composition of the Moon.

Chandrayaan-3 comprised three main components:

  • Chandra's Surface Thermophysical Experiment (ChaSTE) will measure the thermal conductivity and temperature of the lunar surface.
  • Instrument for Lunar Seismic Activity (ILSA) will measure the seismicity around the landing site.
  • Langmuir Probe (LP) will estimate near-surface plasma density over time.
  • Alpha Particle X-Ray Spectrometer (APXS) will derive the chemical composition and infer mineralogical composition of the lunar surface.
  • Laser-Induced Breakdown Spectroscope (LIBS) will determine the elemental composition (Mg, Al, Si, K, Ca, Ti, Fe) of lunar soil and rocks around the lunar landing site.

Propulsion module

  • Spectro-polarimetry of Habitable Planet Earth (SHAPE) will study spectral and polarimetric measurements of Earth from the lunar orbit in the near-infrared (NIR) wavelength range (1–1.7 μm).

Mission profile

Chandrayaan-3 was launched aboard an LVM3-M4 rocket on 14 July 2023, at 2:35 pm IST from Satish Dhawan Space Centre Second Launch Pad in Sriharikota , Andhra Pradesh , India, entering an Earth parking orbit with a perigee of 170 km (106 mi) and an apogee of 36,500 km (22,680 mi).

After a series of manoeuvres that placed Chandrayaan-3 in a trans-lunar injection orbit, ISRO performed a lunar-orbit insertion (LOI) on 5 August, successfully placing the Chandrayaan-3 spacecraft into orbit around the Moon. The LOI operation was carried out from the ISRO Telemetry, Tracking, and Command Network (ISTRAC) located in Bengaluru .

On 17 August, the Vikram lander separated from the propulsion module to begin the last phase of the mission.

On 23 August 2023, as the lander approached the low point of its orbit, its four engines fired as a braking manoeuvre at 30 kilometres (19 mi) above the Moon's surface. After 11.5 minutes, the lander was 7.2 km (4.5 miles) above the surface; it maintained this altitude for about 10 seconds, then stabilized itself using eight smaller thrusters and rotated from a horizontal to a vertical position while continuing its descent.

It then used two of its four engines to slow its descent to roughly 150 metres (490 ft); it hovered there for about 30 seconds and located an optimal landing spot before continuing downward and touching down at 12:32 UTC .

  • Propulsion Module: Carries lander and rover to 100 by 100 kilometres (62 mi × 62 mi) orbit, with operation of experimental payload for up to 6 months.
  • Lander Module: 1 Lunar Day (14 Earth Days)
  • Rover Module: 1 Lunar Day (14 Earth Days)
  • ISRO Chairperson: S. Somanath
  • Mission Director: S. Mohanakumar
  • Associate Mission Director: G. Narayanan
  • Project Director: P. Veeramuthuvel
  • Deputy Project Director: Kalpana. K
  • Vehicle Director: Biju C. Thomas

In December 2019, ISRO requested the initial funding of the project, amounting to ₹ 75 crore (US$13 million), out of which ₹ 60 crore (US$10 million) would be for meeting expenditure towards machinery, equipment, and other capital expenditure, while the remaining ₹ 15 crore (US$2.6 million) was sought for operating expenditure.

Confirming the existence of the project, ISRO's former chairman K. Sivan stated that the estimated cost would be around ₹ 615 crore (equivalent to ₹ 724 crore or US$120 million in 2023).

Since reaching the moon's south pole, Chandrayaan-3 deployed the Pragyan rover to explore the cratered surface, harnessed integrated cameras to send back videos of its environment, and even started working on the research objectives planned for a two-week stay on the moon.

The first video of the rover, posted on 25th August 2023, showed it leaving the Vikram lander on a ramp and driving onto the Moon. ISRO posted the video in a thread on X that also included footage from the lander approaching its landing site and kicking up dust as it touched down on the surface. ISRO wrote afterwards that the rover’s two scientific instruments had been turned on and that it had moved eight meters.

The lunar crater that the Pragyan rover of Chandrayaan-3 encountered on 27th August 2023, as seen by the Navgation Camera

On 26th August, ISRO posted a new video, shot from the lander, of the rover’s drive away, moving almost out of the lander’s sight. On 27th August, it published two pictures after the rover encountered a large crater positioned 3 metres ahead of it's location. However, the rover safely headed on a new path afterwards.

ISRO also released a first-of-its-kind data from the observations made by ChaSTE (Chandra’s Surface Thermophysical Experiment), one of the four instruments present on the lander module. ChaSTE was meant to study the heat conductivity of the Moon’s surface and measure the differences in temperatures at different points on and below the surface, with the overall objective of creating a thermal profile of the Moon.

The graph of temperature variation across the lunar topsoil at a point in the solar polar region, as measured by the ChaSTE instrument

The first set of data released by ISRO showed a very sharp difference in temperatures just above and below the surface of the Moon. A graphical plot put out by ISRO showed that while temperatures on the surface were over 50 degree Celsius, they dropped to nearly -10 degree Celsius just a few millimetres below the surface. The measurements suggested that the topsoil of the lunar surface did not conduct heat very well, and insulated the sub-surface from heat.

These measurements were consistent with what is known about the thermal profile of the Moon from previous expeditions and experiments. But this was the first 'direct measurement' of temperatures of the topsoil and the subsoil near the South Pole of the Moon.

ISRO scientist BH Darukesha , while commenting on the findings, said the high range of 70-degree Celsius temperature near the surface was 'not expected'.

On 29th August, ISRO said that the Laser-Induced Breakdown Spectroscope (LIBS) instrument onboard the Pragyan rover has 'unambiguously' confirmed the presence of Sulphur in the lunar surface near south pole, through 'first-ever in-situ measurements'. Notably, it had picked up signals that confirm the presence of Sulphur, whose direct evidence was not available yet.

Apart from Sulphur, the rover also detected other elements including Aluminium (Al), Calcium (Ca), Iron (Fe), Chromium (Cr), Titanium (Ti), Manganese (Mn), Silicon (Si), and Oxygen (O). Additionally, the agency said the search for Hydrogen (H) is also underway.

John Bridges, a professor of Planetary Science at the University of Leicester , UK, told New Scientist that due to the low pressure on the moon it would be 'unlikely' for Chandrayaan-3 to find liquid water near to the surface – even in areas where the temperature was above freezing point so water would not be trapped in ice – because it would boil away, although at lower depths the pressure could rise enough to allow liquid water. However, he also added that it’s 'too early', to interpret the readings from Chandrayaan-3. “But it’s fantastic they’re getting data,” Bridges said. “You can’t help comparing it to certain other space agencies; engineers are just getting on now and doing it. They’re sort of overtaking Russia.” he concluded.

Congratulating the ISRO team behind the successful Chandrayaan-3 Moon Mission at ISRO Telemetry, Tracking and Command Network in Bengaluru, Prime Minister Narendra Modi announced that the touchdown point of the Vikram lander would henceforth be known as Shiv Shakti point. He further declared August 23, the day the Vikram lander landed on the moon, as National Space Day.
