The document summarizes India's first lunar exploration mission, Chandrayaan-1. It provides details on the mission objectives, payload instruments, key events and accomplishments of the mission. Chandrayaan-1 was launched in 2008 and successfully studied the moon's topography and mineral composition using onboard instruments over its lifetime of 312 days in lunar orbit. The mission helped map the lunar surface and confirmed the presence of water ice and other minerals on the moon. It established India as the fifth nation to place a spacecraft in lunar orbit.

- 3. CHANDRAYAAN mission was India's “ first lunar exploration”. It was been launched by a modified version of PSLV C11. It was an unmanned lunar exploration undertaken by ISRO( Indian space research organization) It was launched on 22nd October 2008; 6:23 IST from SATISH DHAWAN SPACE CENTRE , SRIHARIKOTA, ANDHRA PRADESH.
- 4. Organization Indian Space Research Organization Mission type Orbiter Satellite of Moon Launch date 22 October 2008 from Sriharikota, India Launch vehicle PSLV-C11 Mission duration 2 years NSSDC ID 2008-052A Home page Chandrayaan-1 Mass 523 kg (1,153 lb) Orbital Elements Eccentricity near circular Inclination polar Apoapsis initial 7,500 km (4,660 mi), final 100 km (62 mi) Periapsis initial 500 km (311 mi), final 100 km (62 mi)
- 6. The main objective was to carry out scientific studies and to conduct high- resolution mapping of topographic features in 3D,distribution of various minerals and chemical species such as radioactive nuclides that cover the surface of the moon. To Impact a sub-satellite ( Moon Impact Probe -MIP ) on the surface on the Moon as a fore-runner to future soft landing missions.
- 7. Search for surface or sub-surface water- ice on the Moon, specially at lunar poles. Another objective was to harness several science payloads, lunar craft and the launch vehicle with suitable ground support system.
- 8. After full integration, the Chandrayaan-1 spacecraft (left) is seen being loaded into the Thermovac Chamber (right) Mass 1380 kg at launch, 675 kg at lunar orbit, and 523 kg after releasing the impactor. Dimensions Cuboid in shape of approximately 1.5 m. Communications X band, 0.7 m diameter parabolic antenna for payload data transmission. The Telemetry, Tracking & Command (TTC) communication operates in S band frequency.
- 9. Power The spacecraft was mainly powered by its solar array, which included one solar panel covering a total area of 2.15 x 1.8 m generating 700 W of power, which was stored in a 36 A·h Lithium-ion battery. Propulsion The spacecraft used a bipropellant integrated propulsion system to reach lunar orbit as well as orbit and altitude maintenance while orbiting the Moon. Navigation and Control The craft was 3-axis stabilized with two star sensors, gyros and four reaction wheels.

- 13. CHANDRAYAAN -1 was sent to moon in a series of orbit increasing man oeuvres around the earth as opposed to the launching of craft on a direct trajectory to moon. Chandrayaan -1 successfully completed the lunar orbit insertion operation on 8th Nov 2008, with this India became the fifth nation to put vehicle in lunar orbit. The MIP landed on lunar surface on 14th Nov 2008, which kept on sending information to the mother satellite. The M3 retrieved the presence of iron and also changes in rock and mineral composition.
- 14. ISRO claims that the landing sites of the APOLLO moon mission have been mapped The craft completed 3000 orbits acquiring 70,000 images of lunar surface , which was quite a record. ISRO officials estimated that more than 40,000 images were sent in 75 days. On 26th Nov 2008, TMC acquired images of peaks and craters on the surface. On 25th March 2009, Chandrayaan beamed back the first image of earth.
- 15. Chandrayaan-I completed 312 days in orbit It made nearly 3,400 orbits around the moon Indian deep space network (IDSN) noticed a number of technical failures. But ISRO announced that the mission was 90% completed
- 16. To construct the complex spacecraft with 11- payloads. To place the spacecraft in a circular orbit around the moon. To place the flag of India on the moon. To carry out imaging operation and to collect data on mineral content. Discovery of large caves on the lunar surface.
- 17. Moon surface picture taken from the equatorial region by Chandrayaan-1
- 18. Picture of the lunar surface taken from the polar region by Chandrayaan-1 The second picture has been taken over the equatorial region of the Moon. This picture was taken on November 13, 2008, by Chandrayaan-1’s TMC.
- 19. The American institute of Aeronautics and Astronautics(AIAA) had selected ISRO’s Chandrayaan-1 mission as one of its annual AIAA Space 2009 awards.
- 20. The scientists considered instrumental to the success of the Chandrayaan-1 project are:: G. Madhavan Nair – Chairman, Indian Space Research Organisation T. K. Alex – Director, ISAC (ISRO Satellite Centre) Mylswamy Annadurai – Project director S. K. Shivkumar – Director - Telemetry, Tracking and Command Network. George Koshi –Mission Director Srinivasa Hegde – Mission Director M Y S Prasad – Associate Director of the Sriharikota Complex and Range Operations Director J N Goswami – Director of the Ahmedabad-based Physical Research Laboratory and Principal Scientific Investigator of Chandrayaan-1 Narendra Bhandari – Head, ISRO`s Planetary Sciences and Exploration program.
- 21. It is a joint mission proposed by ISRO and Russian Federal Space Agency. The projected cost is Rs 425 crores. The mission is proposed to be launched in 2013 by a GSLV launch vehicle. It includes a lunar orbiter and a rover and a lander. There would be 7 payloads, 5 for the orbiter and 2 for the rover. CURRENT STATUS:: On 30 August 2010, ISRO has finalized payloads for CHANDRAYAAN -2 mission.
- 22. India’s first lunar exploration. India has started its journey to moon. The Chandrayaan-1 was one of the “touchstones of India”.
