The space agency said a committee would analyse and make recommendations into today’s episode and with the implementation of those recommendations “ISRO will come back soon with SSLV-D2.” “SSLV-D1 placed the satellites into 356 km x 76 km elliptical orbit instead of 356 km circular orbit.
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,” ISRO said in an update on its official Twitter handle.

It added a detailed statement by ISRO Chairman S Somanath will be “uploaded soon.” In its maiden SSLV mission, the launch vehicle carried The Earth Observation Satellite EOS-02 and the co-passenger student satellites AzaadiSAT. SSLV had suffered ‘data loss’ in its terminal stage, after performing “as expected” in all stages. It had earlier after lifted off from the spaceport here on Sunday morning.
Speaking about the mission, ISRO Chairman S. Somanath said: “The SSLV-D1 mission was completed. All the stages of the rocket performed as expected. There is some data loss in the terminal stage of the rocket.” He said the data is being gathered to know the status of the mission.
The three-staged SSLV-D1 is primarily powered by solid fuel (total 99.2 ton) and also has a velocity trimming module (VTM) powered by 0.05 ton of liquid fuel for precise injection of satellites.
India’s newest rocket is 34-metre tall and weighs 120 ton.
As per the flight plan, just over 12 minutes into its flight, the SSLV-D1 should deliver into space the EOS-2 satellite and then the AZAADISAT a few seconds later.
