Launch & failure
PSLV-D1 was launched at 05:12 a.m. IST on 20 September 1993 from Satish Dhawan Space Centre (then called "Sriharikota Launching Range"). A large disturbance occurred at the point of second stage separation and one of the retro rockets of the second stage failed due to software error in on board guidance and control processor. About 12 minutes after launch, the vehicle fell back to earth and crashed in the Bay of Bengal. The satellite IRS-1E could not be placed in orbit and the mission was a total failure.
