Answer 1

Chandrayaan-1, India's first mission to the Moon was launched on 22 October 2008 using the Polar Satellite Launch Vehicle (PSLV-C11). The satellite made more than 3400 orbits around the Moon and the mission was concluded when the communication with the spacecraft was lost on 29 August 2009. The primary science objective of the mission was to prepare a three dimensional atlas of both near and far side of the Moon and to conduct chemical and mineralogical mapping of the entire lunar surface with high spatial resolution.

The most significant result from Chandrayaan-1 is the discovery of the presence of hydroxyl (OH) and water (H2O) molecules on the lunar surface. The inference of sub surface water-ice deposits in the base of craters in permanent sun shadow, detection of possible existence of water molecules in the lunar environment, validation of Lunar Magma Ocean hypothesis, detection of reflection of 20% of solar wind protons, detection of presence of Mg, Al, Si, Ca on the lunar surface and three dimensional conceptualization of many lunar craters of interest are other scientific results from Chandrayaan-1.

Successful realization of this mission has led to all round development in satellite technology, design, development and fabrication of a variety of experimental payloads, setting up communication, navigation and control system for going beyond the geostationary orbit, acquisition and transfer of data from lunar orbit through Indian Deep Space Network (IDSN) with 18-m and 32-m antennae to ground station network and establishment of Indian Space Science Data Centre (ISSDC) at Byalalu as the primary data center for Indian Space Science Missions.

Answer 2

Explanation:

★★★★★SURE BUDDY ★★★★★★

Chandrayaan-1, India's first mission to Moon, was launched successfully on October 22, 2008 from SDSC SHAR, Sriharikota.

The mission was a major boost to India's space program, as India researched and developed its own technology in order to explore the Moon. The vehicle was inserted into lunar orbit on 8 November 2008.
