Microsat-TD was an Earth observing satellite developed by ISRO. Its launch marked India's 100 satellites in space. This satellite could capture images at night by imaging in infrared spectrum.
MICROSAT-TD satellite was launched at 0359 UTC on 12 January 2018 by PSLV-C40 and its deployment profile was previously rehearsed on PSLV-C38 mission. Microsat-TD was launched along with Cartosat-2F, INS-1C and 28 satellites from 6 countries and separated 1 hour 45 minutes after first stage ignition. 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.
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.
