Microsat-TD was an Earth observing satellite developed by ISRO.[2] Its launch marked India's 100 satellites in space.[3] This satellite could capture images at night by imaging in infrared spectrum.[4][5]

Launch
editMICROSAT-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.
Payload
editMicrosat-TD was IMS-1 based technology demonstrator carrying optical imaging payload in two bands.[11][12]
- 0.8 meter resolution (panchromatic, 0.5 -0.85 μm) with 3.2 km swath
- 6 meter resolution (IR, 3.7-4.8 μm and 8-12 μm) with 2 km swath
End of mission
editTo 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]
