PURPOSE
The primary objective of ISRO's 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.
BACKGROUND
Chandrayaan-2 launched 2019-July-22 @ 09:13 UTC from Satish Dhawan Space
Centre on Sriharikota Island, India. Launch vehicle was a GSLV-MK3.
Mission consists of an orbiter, a lander ("Vikram") and a rover ("Pragyan")
After launch into Earth parking orbit (170 x 40400 km altitude), a series
of maneuvers will progressively raise the apogee of the spacecraft until
a subsequent trans-lunar injection burn. Injection to lunar transfer orbit
will occur 2019-Aug-14.
It was inserted into an initial elliptic lunar orbit on Aug 20
(114 x 18072 km) and the first of a sequence of maneuvers executed,
lowering apoapsis to 4412 km.
The orbiter will then be placed in a 100 km circular polar orbit with a
series of engine burns. Subsequently, the lander will separate and touch
down at the predetermined site close to the lunar south pole.
Touchdown is to occur 2019-Sep-07 on a high plain between two craters,
Manzinus C and Simpelius N, about 70 degrees south of the equator.
The orbiter mission covers 1 year, in a 100-km circular polar orbit.
The six-wheeled Pragyan rover, whose name means "wisdom" in Sanskrit, will
be deployed from a ramp after landing. It is solar-powered and capable of
traveling up to 500 meters on the lunar surface at a speed of 1 cm/s.
The lander/rover missions are planned for 14-15 days (1 lunar daylight
interval).
