Launch Notes

India's first launch vehicle assembled without Russian assistance and PSLV's first operational flight. Due to a gaseous helium leak, the vehicle failed to place the payload in the desired circular sun-synchronous orbit and instead left it in an elliptical one. While not a total failure, this was a suboptimal outcome.

Wiki

IRS-1D is the seventh satellite in the Indian Remote Sensing satellite series of Earth Observation satellites, built, launched, and maintained by the Indian Space Research Organisation. The satellite has similar capabilities as that of ISRO's IRS-1C satellite with some improvements added for better imagery, particularly in thematic mapping.
