EOS-02 (formerly known as Microsat-2A) was an Indian Earth observation microsatellite developed by the Indian Space Research Organisation as a test payload on the maiden launch of the Small Satellite Launch Vehicle (SSLV).[1] EOS-02 was based on Microsat-TD. The objective behind EOS-02 was to realize and fly an experimental imaging satellite with short turnaround time to showcase launch on demand capability.[2]

It was intended to be used for cartographic applications at a cadastral level, urban and rural management, coastal land use and regulation, utilities mapping, development and various other GIS applications. The satellite carried two payloads: a mid-wavelength and a long-wavelength infared camera with a 6m resolution.[3]

Launch

EOS-02 was launched on Small Satellite Launch Vehicle's maiden flight SSLV-D1 at 03:48 UTC / 09:18 IST on 7 August 2022,[4][5] but due to the final VTM stage failure, the rocket entered a transatmospheric orbit of 356 km x 76 km (221 mi x 47 mi) instead of the planned circular 356 km (221 mi) circular orbit. As a result, both satellites onboard (EOS-02 and AzaadiSAT) were destroyed during reentry.[6]

Satellites are no longer usable. Issue is reasonably identified. Failure of a logic to identify a sensor failure and go for a salvage action caused the deviation. A committee would analyse and recommend. With the implementation of the recommendations, ISRO will come back soon with SSLV-D2. A detailed statement by Chairman, ISRO will be uploaded soon" (Tweet) – via Twitter.
