Chandrayaan 2, India’s second lunar mission, was
scheduled to be launched on 15 July from the Satish Dhawan Space Centre at
Sriharikota in Andhra Pradesh. However, the launch got delayed due to technical
Chandrayaan 2 is ISRO’s first attempt to make a
soft landing on the Moon. If successful, India will join the US, the former
Soviet Union, and China—the only three other nations to have soft landed on
Chandrayaan-2 will comprise of an Orbiter,
Lander named ‘Vikram’ and Rover named ‘Pragyan’
The orbiter will circle the moon and provide
information about its surface, while the lander will make a soft landing on the
surface and send out the rover. The rover will be used mostly for in situ
The entire lifecycle of the Lander and Rover
will be one lunar day, which is equivalent to 14 earth days while the Orbiter
will continue for one year.
The soft landing on lunar South Pole was planned
for September 6th. The date had been chosen because the landing site
will remain well illuminated by sunlight over the next one month while the
Lander and Rover would work and collect data. Also, there is no lunar eclipse
during this period.
Chandrayaan-2 will carry out extensive
three-dimensional mapping of the topography of the lunar South Pole region. It will
also determine its elemental composition and seismic activity. If successful, India
will be the first country to soft land on lunar South Pole. So far, all the landing
on the moon have taken place in the equatorial region
The mission would also try to assess the
abundance and distribution of water on the lunar surface.
Chandrayaan-2 will launch aboard a
Geosynchronous Satellite Launch Vehicle Mark III, (GSLV -MK III) rocket- the
most powerful rocket ISRO has built.
