ISRO says satellites launched by SSLV ‘no longer usable’: Top factors to notice

ISRO’s Small Satellite Launch Vehicle (SSLV) lifted off from the spaceport in Sriharikota at 9.18 AM. But virtually instantly, one thing went mistaken. Minutes after launch ISRO chairman S Somanath stated that the SSLV D1 mission suffered “data loss” at a terminal stage. And not lengthy after that, ISRO introduced that the 2 satellites deployed by the launch car wouldn’t be usable. Here is what went mistaken.

Data loss

“All stages performed as expected. The first stage performed and separated, the second stage performed and separated, the third stage also performed and separated, and in the terminal phase of the mission, some data loss is occurring. We are analysing the data and we will come back on the status of the satellites as well as the vehicle performance soon,” stated Somanath from Mission Control Centre, minutes after the launch, in keeping with PTI.

“SSLV-D1/EOS-02 Mission update: 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,” stated the house company in a tweet. The mechanism put in place to determine a sensor failure didn’t work and thereby, the launch car did not provoke a salvage motion that may have made deviations.

What was the rocket carrying

The rocket was carrying EOS-02 which is an Earth remark satellite tv for pc. It was additionally carrying AzaadiSAT, a scholar satellite tv for pc. It went on to finish all phases of the lift-off efficiently till the terminal stage, which is the place ISRO scientists noticed the “data loss”. After that, SSLV positioned the satellites in an elliptical orbit, as a substitute of a round orbit, rendering them, “no longer usable.”

(1/2) SSLV-D1/EOS-02 Mission replace: SSLV-D1 positioned the satellites into 356 km x 76 km elliptical orbit as a substitute of 356 km round orbit. Satellites are not usable. Issue within reason recognized. Failure of a logic to determine a sensor failure and go for a salvage motion

Due to this malfunction, the launch car put the satellites right into a 365km x 76 km elliptical orbit as a substitute of the supposed 365 km round orbit, which means that the science goals of the mission couldn’t be accomplished.

Now, a committee will analyse the launch and make suggestions for enhancements. After implementing these suggestions, ISRO will come again for one more try with the SSLV-D2 mission.
