Chandrayaan-3 was launched from Satish Dhawan Space Centre on 14 July 2023. The spacecraft entered lunar orbit on 5 August, and became the first lander to touch down near the lunar south pole[12] on 23 August at 18:03 IST (12:33 UTC), making India the fourth country to successfully land on the Moon, and at 69°S, the southernmost lunar landing, until IM-1 landed further southwards in Malapert A crater on 22 February 2024.[13][note 2] The lander was not built to withstand the cold temperatures of the lunar night, and sunset over the landing site ended the surface mission twelve days after landing.[17][18] The propulsion module, still operational, transited back to a high Earth orbit from lunar orbit on 22 November 2023 for continued scientific observations of Earth.[19] It operated until 22 August 2024.[4]
In 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.[20] The lander was scheduled to touch down on the lunar surface on 6 September 2019 to deploy the Pragyan rover. The lander lost contact with mission control, deviated from its intended trajectory while attempting to land near the lunar south pole, and crashed.[21][22]
The lunar south pole region holds particular interest for scientific exploration. Studies show large amounts of ice there. The ice could contain solid-state compounds that would normally melt under warmer conditions elsewhere on the Moon—compounds which could provide insight into lunar, Earth, and Solar System history. Mountains and craters create unpredictable lighting that protect the ice from melting, but they also make landing there a challenging undertaking for scientific probes. For future crewed missions and outposts, the ice could also be a source of oxygen, of drinking water as well as of fuel due to its hydrogen content.[23][24]
For the first time on the lunar surface, a laser beam from NASA's Lunar Reconnaissance Orbiter was broadcast on 12 December 2023, and it was reflected back by a tiny NASA retroreflector on board the Vikram lander. The purpose of the experiment was to determine the retroreflector's surface location from the moon's orbit. The Chandrayaan-3 lander's Laser Retroreflector Array (LRA) instrument began acting as a location marker close to the lunar south pole. Through multinational cooperation, the LRA was housed on the Vikram lander. On a hemispherical support framework, it consists of eight corner-cube retroreflectors. This array enables any orbiting spacecraft equipped with appropriate instruments to use lasers ranging from different directions. The 20 gram passive optical instrument is intended to survive for several decades on the lunar surface.[27]
Objectives
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.[28]
Spacecraft
Design
Chandrayaan-3 comprises three main components: a propulsion module, lander module, and rover.
Chandrayaan-3 encapsulated within LVM3's payload fairing
Chandrayaan-3 integrated components
Propulsion module
The propulsion module carried the lander and rover configuration to a 100-kilometre (62 mi) lunar orbit. It was a box-like structure with a large solar panel mounted on one side and a cylindrical mounting structure for the lander (the Intermodular Adapter Cone) on top.[29][30]
A few months after the conclusion of the lander portion of the mission, ISRO officials said that the propulsion module was equipped with two radioisotope heating units (RHU), designed and developed by BARC (Bhabha Atomic Research Centre). RHUs keep spacecraft at their operational temperature using the decay of radioactive material, to generate electricity to power heaters. Chandrayaan-3 project director P Veeramuthuvel said ISRO may use nuclear resources to maintain instruments in future rovers. ISRO officials later said the RHUs could not be installed on Chandrayaan-3's Vikram lander and Pragyan rover because it would have increased their mass. This reduced their maximum lifespan to 14 Earth days, or 1 lunar day.[31][32][33] On 4 December 2023, ISRO reported that the propulsion module was reinserted into an orbit around the Earth.[19] The primary objective of the reinsertion was to allow Earth observations by spectral and polarimetric instruments.[34] It operated until 22 August 2024.[4]
Propulsion module
Vikram lander
The Vikram lander was responsible for the soft landing on the Moon. It is also box-shaped, with four landing legs and four landing thrusters capable of producing 800 newtons of thrust each. It carried the rover and had various scientific instruments to perform on-site analysis.[35][36] The lander has four variable-thrust engines with slew rate changing capabilities, unlike Chandrayaan-2's lander, which had five, with the fifth one being centrally mounted and capable only of fixed thrust. One of the main reasons for Chandrayaan-2's landing failure was altitude increase during the camera coasting phase. This was removed by allowing the lander to control altitude and thrust during all phases of descent. Altitude correction rate was increased from Chandrayaan-2's 10°/s to 25°/s with Chandrayaan-3. Additionally, the Chandrayaan-3 lander is equipped with a laser Doppler velocimeter (LDV) to allow measuring altitude in three directions.[37][38] The impact legs were made stronger compared to Chandrayaan-2 and instrumentation redundancy was improved. It targeted a more precise 16 km2 (6.2 sq mi) landing region based on images provided by the Orbiter High-Resolution Camera (OHRC) onboard Chandrayaan-2's orbiter. ISRO improved the structural rigidity, increased polling in instruments, increased data frequency and transmission, and added additional multiple contingency systems to improve lander survivability in the event of failure during descent and landing.[39][38]
Lander
Rover pragyan
The Pragyan rover is a six-wheeled vehicle with a mass of 26 kilograms (57 pounds). It is 917 by 750 by 397 millimetres (36.1 in × 29.5 in × 15.6 in) in size.[40] The rover is expected to take multiple measurements to support research into the composition of the lunar surface, the presence of water ice in the lunar soil, the history of lunar impacts, and the evolution of the Moon's atmosphere.[41][12]
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.
Radio Anatomy of Moon Bound Hypersensitive Ionosphere and Atmosphere—Langmuir Probe (RAMBHA-LP) will estimate the near-surface plasma density over time.[42]

Launch
Chandrayaan-3 was launched aboard an LVM3-M4 rocket on 14 July 2023, at 09:05 UTC from Satish Dhawan Space CentreSecond 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). On 15 November 2023, the Cryogenic Upper Stage (C25) of the rocket (NORAD ID: 57321) made an uncontrolled re-entry into the Earth's atmosphere around 9:12 UTC. The impact point is predicted over the North Pacific Ocean and the final ground track did not pass over India.[44][45][46]
On 17 August, the Vikram lander separated from the propulsion module to begin landing operations.[52]
Landing
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 12:33 UTC.[35][53]

Surface operations
On 3 September, the rover was put into sleep mode after it had completed all of its assignments. Its batteries were charged and receiver left on, according to ISRO, in preparation for the impending lunar night.[68] "The rover's payloads are turned off and the data it collected has been transmitted to Earth via the lander", the statement said. Chandrayaan-3's lander and rover were expected to operate only for one lunar daylight period, or 14 Earth days, and the on-board electronics were not designed to withstand the −120 °C (−184 °F) nighttime temperatures on the Moon.[69] On 22 September, the lander and rover missed their wake-up calls,[70][71] and by 28 September neither had responded, diminishing hopes for further surface operations.[72]
Hop experiment
Vikram fired its engines for a brief 'hop' on the lunar surface on 3 September, ascending 40 cm (16 in) off the lunar surface and translating a similar distance laterally across the surface.[73] The test demonstrated capabilities to be used in potential future sample return missions. The instruments and rover deployment ramp were retracted for the hop and redeployed afterwards.[74][75][10]
Propulsion module reinserted to orbit around Earth
The propulsion module of Chandrayaan-3 was moved out of lunar orbit to an orbit around Earth.[34][76] Although the plan was to operate SHAPE for three months in lunar orbit, it was decided to utilise over 100kg of fuel left in the PM after one month of operation to derive additional information for future lunar missions, and determine strategies for sample return missions and gravity-assisted flyby missions. ISRO's flight dynamics team had developed software to be validated through these return manoeuvres.
The first lunar bound apogee raising manoeuvre was executed on 9 October 2023 raising the apogee from 150 km to 5112 km and orbital period from 2.1 hours to 7.2 hours. The Trans-Earth Injection was done on 13 October 2023 with a targeted orbit of ~380,000 x 180,000 km. This was followed by four lunar flyby's with the last one on 7 November 2023. The module exited lunar SOI on 10 November 2023 and had the first perigee crossing on 22 November 2023 at an altitude of about 154,000 km. The propulsion module is currently orbiting Earth with a perigee and apogee altitude that vary during its trajectory and the predicted minimum perigee altitude is 115,000 kilometres (71,000 mi), with an orbital period of nearly 13 days with 27 degree inclination. The SHAPE payload is operated whenever Earth is in its field of view, as well during special events such as the 28 October 2023 solar eclipse. The SHAPE payload operations are planned to continue further.[77] The Propulsion module operated until 22 August 2024.[4]

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 but lasted for more than an year.[78]
Lander module: one lunar daylight period (14 Earth days).[78]
Rover module: one lunar daylight period (14 Earth days).[78]
In December 2019, ISRO requested the initial funding of the project, amounting to ₹750 crore (US$90 million), out of which ₹600 crore (US$72 million) would be for meeting expenditure towards machinery, equipment, and other capital expenditure, while the remaining ₹150 crore (US$18 million) was sought for operating expenditure.[85] Amit Sharma, CEO of an ISRO vendor, said, "With local sourcing of equipment and design elements, we are able to reduce the price considerably."[86]
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$87 million in 2023).[87][88][89]
Results
The Associated Press, while commenting on the success of the mission, said, "The successful mission showcases India's rising standing as a technology and space powerhouse and dovetails with Prime Minister Narendra Modi's desire to project an image of an ascendant country asserting its place among the global elite."[90] About results on water existence, "There was no word on the outcome of the rover searches for signs of frozen water on the lunar surface (...)".[90]
Temperature variation
ISRO also released data from the observations made by ChaSTE (Chandra's Surface Thermophysical Experiment), one of the four instruments present on the lander module. ChaSTE was designed 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.
ISRO scientist BH Darukesha said the high range of 70-degree-Celsius (158-degree-Fahrenheit) temperature near the surface was "not expected".[91]
Detection of sulfur
On 29 August, ISRO reported that the laser-induced breakdown spectroscope (LIBS) instrument on board the Pragyan rover has "unambiguously" confirmed the presence of sulfur in the lunar surface near the south pole, through "first-ever in-situ measurements".[92][93] The presence of sulfur on the Moon has been known before;[94] however, it was detected for the first time at the south pole by the rover.[95]
Noah Petro, a project scientist at NASA, while speaking to the BBC, stated that while sulfur has been known to be in the lunar regolith from Apollo program samples, he described Pragyan's findings as a "tremendous accomplishment".[96]
Apart from sulfur, the rover also detected other elements including aluminium (Al), calcium (Ca), iron (Fe), chromium (Cr), titanium (Ti), manganese (Mn), silicon (Si), and oxygen (O).[97] The agency said it is also searching for hydrogen (H).[98][99]
Plasma measurement
On 31 August, ISRO released plasma density data from the RAMBHA Instrument aboard the Vikram lander. Initial assessments reported relatively low plasma densities above the lunar surface varying from 5 to 30 million electrons per m3. The evaluation pertains to early stages of the lunar day. The probe aims to explore the changes in the near-surface plasma environment throughout the duration of the lunar day.[100]
Seismic measurements
On the same day, ISRO released data from the ILSA payload on the lander, providing vibration measurements of the rover movement on 25 August, and a presumed natural event on 26 August. The cause of the latter event is a subject of investigation,[101] it is suspected to be a moonquake.[99]
Domestic reactions
Chandrayaan-3's landing live stream on ISRO's official YouTube channel received eight million concurrent viewers,[102] which is the highest in YouTube's history for a live video.[103][104]
Congratulating the ISRO team behind the successful Chandrayaan-3 mission at ISRO Telemetry, Tracking and Command Network in Bengaluru, Indian Prime Minister Narendra Modi announced that the touchdown point of the Vikram lander would henceforth be known as Statio Shiv Shakti.[105] He further declared 23 August, the day the Vikram lander landed on the Moon, as National Space Day.[106][107]
ISRO chief S. Somanath proclaimed "India is on the Moon" after the successful touchdown.[108] "We learnt a lot from our failure and corrected it. It's now 14 days of work and we have to conduct experiments," he told India Today.[109]
P Veeramuthuvel, the project director of the mission said, "It's a great moment of happiness. On behalf of the team it gives me immense satisfaction on achieving this goal as the Project Director of the mission. The entire mission operations right from launch till landing happened flawlessly as per the timeline".[110] S. Mohana Kumar, the mission director, said that Chandrayaan-3 was a "team effort".[111]
Meanwhile, former ISRO chief K Sivan, under whose tenure the Chandrayaan-2 was launched said, "We are really excited to see this grand success. For this, we have been waiting for the last four years. This success is sweet news for us and for the entire nation."[112]
Rahul Gandhi, the leader of congress, also celebrated Chandrayaan-3's success, calling it a result of "tremendous ingenuity and hard work" by the country's scientific community. "Since 1962, India's space program has continued to scale new heights and inspire generations of young dreamers," he posted on X.[113]
Delhi chief minister Arvind Kejriwal congratulated the scientists of ISRO on the successful landing and termed it a "historic" moment. He wrote "This is historical. It's a significant achievement for the country. It's a matter of pride for all of us. The success of Chandrayaan-3 is a result of the hard work of all citizens, ISRO scientists, engineers, and employees. Congratulations to everyone involved. Bharat Mata ki jai."[114]
Josef Aschbacher, director general of the European Space Agency, said: "Incredible! Congratulations to ISRO, Chandrayaan-3, and to all the people of India!! What a way to demonstrate new technologies AND achieve India's first soft landing on another celestial body. Well done, I am thoroughly impressed."[116][117][118]
Abdulla Shahid, the foreign minister of Maldives, wrote "As a South Asian nation, and neighbour, we are proud of the successful landing of Chandrayaan 3 near the moon's south pole. This is a success for all of humanity! Opening new avenues for new areas of exploration."[117]
Bill Nelson, the administrator of NASA wrote "Congratulations ISRO on your successful Chandrayaan-3 lunar South Pole landing and congratulations to India on being the 4th country to successfully soft-land a spacecraft on the Moon. We're glad to be your partner on this mission".[119][118]
Cyril Ramaphosa, the president of South Africa said "This for us, as the BRICS family, is a momentous occasion and we rejoice with you. We join you in the joy of this great achievement."[116]
The Kremlin quoted Russian president Vladimir Putin's message to Indian president Droupadi Murmu and Modi, "Please, accept my heartfelt congratulations on the occasion of the successful landing of the Indian space station Chandrayaan-3 on the Moon near its South Pole. This is a big step forward in space exploration and certainly a testament to the impressive progress made by India in the area of science and technology".[120]
Nepal prime minister Pushpa Kamal Dahal said "I congratulate Prime Minister Shri Narendra Modi ji and ISRO team of India on successful landing of Chandrayan-3 in the surface of the moon today and unleashing of a historic achievement in science and space technology."[117]
Awards
The Exploration Museum has bestowed upon ISRO the esteemed Leif Erikson Lunar Prize in honor of the space agency's resolute dedication and noteworthy advancements in lunar exploration in 2023.[121]
In recognition of its accomplishments with the historic Chandrayaan-3 mission in 2023, ISRO has been bestowed with the esteemed Aviation Week Laureates Award. Sripriya Ranganathan, Deputy Ambassador at the Indian Embassy in the US, accepted the award on behalf of ISRO.[122]
The Chandrayaan-3 mission team has raised the bar for space exploration, and for that reason, they have been awarded the prestigious 2024 John L. 'Jack' Swigert Jr. Award for Space Exploration. On 8 April 2024, at the opening ceremony of the annual Space Symposium in Colorado, India's Consul General D C Manjunath accepted the prize on behalf of the Indian Space Research Organization.[123]
The International Astronautical Federation has presented Chandrayaan-3 with the World Space Award. The award presentation is slated to take place on October 14 in Milan, during the 75th International Astronautical Congress opening ceremony.[124] According to the International Astronautical Federation, Chandrayaan-3 mission by ISRO exemplifies the synergy of scientific curiosity and cost-effective engineering.[125]
