ISRO’s Small Satellite Launch Vehicle (SSLV) lifted off from the spaceport in Sriharikota at 9.18 AM. But nearly instantly, one thing went unsuitable. Minutes after launch ISRO chairman S Somanath mentioned 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 automobile wouldn’t be usable. Here is what went unsuitable.
Data loss
“All phases carried out as anticipated. The first stage carried out and separated, the second stage carried out and separated, and within the terminal section of the mission, some knowledge loss is happening. We are analyzing the information and we’ll come again on the standing of the satellites in addition to the automobile efficiency quickly,” mentioned Somanath from Mission Control Centre, minutes after the launch, in line 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,” mentioned the area company in a tweet. The mechanism put in place to determine a sensor failure didn’t work and thereby, the launch automobile didn’t provoke a salvage motion that might have made deviations.
What was the rocket carrying
The rocket was carrying EOS-02 which is an Earth statement 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 an alternative 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 an alternative of 356 km round orbit. Satellites are now not usable. Issue is fairly recognized. Failure of a logic to determine a sensor failure and go for a salvage motion

Due to this malfunction, the launch automobile put the satellites right into a 365km x 76 km elliptical orbit as an alternative of the supposed 365 km round orbit, that means that the science aims of the mission couldn’t be accomplished.
Now, a committee will analyze the launch and make suggestions for enhancements. After implementing these suggestions, ISRO will come again for one more try with the SSLV-D2 mission.
