MICROSAT-TD satellite was launched at 0359 UTC on 12 January 2018[6] by PSLV-C40 and its deployment profile was previously rehearsed on PSLV-C38 mission.[7][8] Microsat-TD was launched along with Cartosat-2F, INS-1C and 28 satellites from 6 countries[9] and separated 1 hour 45 minutes after first stage ignition.[10] Duration of PSLV C40 mission was 2 hours and 21 minutes, making it the longest mission of PSLV at that time.
Microsat-TD was IMS-1 based technology demonstrator carrying optical imaging payload in two bands.[11][12]
To reduce its orbital stay, Microsat-TD was de-orbited while depleting its left over propellant near the end of its life. Satellite reentered within a month, on 27 November 2020.[1]
