Chandrayaan 2 [ISRO]
Chandrayaan-2 is an Indian mission to the Moon, which will have an Orbiter, a Lander and a Rover. After reaching the 100 km lunar orbit, the Lander housing the Rover will separate from the Orbiter. After a controlled descent, the Lander will soft land on the lunar surface at a specified site and deploy a Rover.
The science goals of the mission are to further improve the understanding of the origin and evolution of the Moon using instruments onboard Orbiter and in-situ analysis of lunar samples using Lander and Rover.
Chandrayaan-2 Structure configuration has been changed from I2K to I3K configuration due to the revision of payload lift off capacity by GSLV. This change will enable accommodating larger propellant tanks. The mission strategy was revised to inject the satellite in a lower initial orbit (170 × 16980 km) with a higher lift-off mass of 3200 kg and the Propulsion System Configuration changed to increase fuel carrying capability of the satellite. The other activities completed are: finalisation of all electrical and mechanical interfaces including the payload interfaces; Preliminary Design Reviews (PDRs) of Bus Systems (Power, Attitude Orbit Control Electronics, Telemetry, Tracking and Command Baseband Systems, RF Systems, Data Handling System, Structure, Thermal Control System, Propulsion System); all systems accommodation studies and initial thermal analysis.
The following five payloads are selected for Orbiter.
The lander carries following instruments:
Following two scientific payloads selected for Indian Rover would carry out elemental analysisof the lunar surface near the landing site.
