Chandrayaan 2 is an Indian Space Research Organization (ISRO) mission comprising an orbiter and a soft lander carrying a rover, scheduled to launch on 15th July, 2019 at 02:51 a.m from Sriharikota.
The primary objective of Chandrayaan-2 is to demonstrate the ability to soft-land on the lunar surface and operate a robotic rover on the surface.
Scientific goals include studies of lunar topography, mineralogy, elemental abundance, the lunar exosphere, and signatures of hydroxyl and water ice.
The Chandrayaan 2 orbiter is a box-shaped craft with an orbital mass of 2379 kg. The Vikram lander has a mass of 1471 kg, including the 27 kg rover. The rover is a 6-wheeled vehicle using solar power.
The orbiter will have a scientific payload comprising a visible terrain mapping camera, a neutral mass spectrometer, a synthetic aperture radar, a near infrared spectrometer, a radio occultation experiment, a soft X-ray spectrometer and solar X-ray monitor.
The lander will carry a camera, seismometer, thermal profiler, and Langmuir probe, while the rover will hold cameras, alpha-proton X-ray spectrometer, and a laser-induced ablation spectroscopy experiment.
Chandrayaan 2 is scheduled to launch between July 9 and 16, 2019 from Satish Dhawan Space Center on Sriharikota Island on an ISRO Geosynchronous Satellite Launch Vehicle (GSLV) Mark III. The lander-orbiter pair will go into an initial elliptical (180 x 24000 km altitude) Earth orbit, followed by a trans-lunar injection.
Both craft go into an initial elliptical lunar orbit. After orbit insertion, the lander and orbiter separate. The orbiter evolves into a 100 km circular polar orbit and the lander brakes from orbit and lands on the surface in the high latitude areas near the south pole.
The orbiter portion of the mission is planned to last 1 year. The rover will be deployed using a ramp shortly after landing and is planned for 14-15 days, one period of lunar daylight.
