New Delhi. The Indian Space Research Organization on Sunday took to its Twitter handle to inform that the SSLV-D1 rocket had placed the satellites in the wrong orbit, hence making it unusable. ISRO further said that ISRO will soon come back with SSLV-D2 after the failure of the SSLV-D1 launch. SSLV-D1 placed the satellites in a 356 km x 76 km elliptical orbit instead of a 356 km circular orbit. The satellites are no longer usable. The problem has been properly identified. ISRO has further explained in its Twitter handle that, ‘Failure of logic to identify sensor failure and go for rescue action leads to deviation. A committee will analyze and make recommendations. With the implementation of the recommendations, ISRO will soon be back with SSLV-D2.”

Let us tell you that ISRO had informed that earlier in the day ISRO had announced the first successful flight of its new satellite launcher, the Small Satellite Launch Vehicle (SSLV).

Launched from the first launchpad of the Satish Dhawan Space Center in Sriharikota, Andhra Pradesh, SSLV-D1 took off at 9:18 am on Sunday, with two small satellites in low-earth orbit (LEO) about 365 km from the equator. deployed. The SSLV was 34 meters long, about 10 meters shorter than PSLV and has a vehicle diameter of two meters as compared to PSLV’s 2.8 metres.

The SSLV was carrying Earth Observation Satellite-02 and a co-passenger satellite AzadiSat. Earlier it was shared by ISRO that after launch, ISRO experienced data loss in the final stages of flight.
ISRO chairman S Somnath had reported the space agency’s first small satellite launch vehicle (SSLV) suffered “data loss” in the terminal stage, though the three stages “performed and separated.”
