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

[edit]

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.

  1. Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
