Chandrayaan-2, the second moon mission of the Indian Space Research Organisation (ISRO), will be carrying laser retroreflector arrays owned by the US space agency National Aeronautics and Space Administration (NASA).
Besides Chandrayaan 2, the laser retroreflector arrays will also be carried to the Moon aboard the Israeli lander Beresheet, which is due to touch down on April 11, 2019. The announcement regarding the same was made during the Lunar and Planetary Science Conference held in Texas in the third week of March 2019.
Built with a total expense of Rs 800 crore, the launch of the second phase of Chandrayaan mission will come a decade after the maiden mission, Chandrayaan-1 was launched on October 22, 2008. Chandrayaan-2 spacecraft will be launched onboard the Geosynchronous Satellite Launch Vehicle (GSLV) Mk-3 in April 2019.
The Indian Space Research Organisation (ISRO) will launch 29 satellites including the primary payload EMISAT on April 1, 2019. The PSLV-C45 (Polar Satellite Launch Vehicle), carrying these satellites onboard, will take off from the Satish Dhawan Space Centre in Sriharikota.
Generally, after the launch mission is over, the rocket engine is left discarded as space debris. However, the ISRO uses the engine for experiments. Once the satellites are put into orbit by PSLV-C45, this fourth stage of the rocket will be brought down, propelled and used as a platform for different experiments by Indian institutions including ISRO.
