- Chandrayaan-2 is the second Indian mission to the Moon. It is designed to have an Orbiter in a 100 km circular orbit, the Vikram Lander which separates from the Orbiter and
lands at the pre-identified site and the Pragyaan Rover to pursue in-situ lunar studies.
The mission is scheduled to be launched in 2019 by GSLV-MkIII from SDSC, Sriharikota.
- To develop and demonstrate the key technologies for end-to-end lunar mission capability, including soft-landing and roving on the lunar surface.
- To expand the lunar scientific knowledge through detailed study of topography, mineralogy, surface chemical composition, thermo-physical characteristics and tenuous lunar atmosphere leading to a better understanding of
the origin and evolution of the Moon.
- Aditya L1 shall be the first space based Indian mission to study the Sun.
- The satellite shall be inserted in a halo orbit around the Lagrangian point 1 (L1) of the Sun-Earth
system, which is 1.5 million km from the Earth. A Satellite placed in the halo orbit around the L1
point has the major advantage of continuously viewing the Sun without any occultation/ eclipses.
- The spacecraft carries seven payloads to observe the photosphere, chromosphere and the outermost layers of the Sun (the corona) using electromagnetic and particle detectors.
- Using the special vantage point of L1, four payloads directly view the Sun and the remaining carry out in-situ studies of particles and fields.
