Microsat-R was claimed to be an earth observing satellite manufactured by DRDO[1] and launched by Indian Space Research Organisation on 24 January 2019 for military use.[2] Satellite served as a target for ASAT test on 27 March 2019.[3]

Launch

Microsat-R, along with KalamsatV2 as piggy-back, was launched on 24 January 2019[4] at 23:37 hrs from First Launch Pad of Satish Dhawan Space Centre. The launch marks the 46th flight of PSLV.[5] After 13 minutes 26 seconds in flight, Microsat-R was injected at targeted altitude of about 277.2 km. This was the first flight of a new variant of PSLV called PSLV-DL with two strap-ons, each carrying 12.2-tonne of solid propellant.[6]

Anti-satellite test

Microsat-R served as target for Indian ASAT experiment on March 27, 2019.[7][8][9] The impact generated more than 400 pieces of orbital debris with 24 having apogee higher than ISS orbit.[10][11] According to initial assessment by DRDO some of the debris (depending on size and trajectory) should re-enter in 45 days.[12] A spokesperson from NASA disagreed, saying the debris could last for years because the solar minimum had contracted the atmosphere that would otherwise cause the debris to reenter.[13] Analysis from a leading space trajectory and environment simulation company AGI has also came to same conclusion that few debris fragments will take more than a year to come down and other debris fragments might pose a risk to other satellites and ISS and these results were also presented in the 35th Space Symposium at Colorado Springs.[14]
