PSLV-C1 was the overall fourth mission of the Polar Satellite Launch Vehicle (PSLV) program by Indian Space Research Organisation (ISRO). The vehicle carried IRS-1D satellite which was deployed in the Sun-synchronous orbit (SSO).[1][2][3][4] This was India's first launch vehicle built without Russian assistance and PSLV's first operational flight placed IRS-1D into a polar orbit. However, it could not place the satellite in the desired circular orbit but in an elliptical orbit due to a leak of helium gas from one of the components. The mission was termed partial failure since the satellite could not be placed at the desired altitude.[5][6]

Launch
PSLV-C1 was launched at 04:47 UTC on 29 September 1997 from Satish Dhawan Space Centre (then called "Sriharikota Launching Range"). The vehicle placed the IRS-1D satellite in the Sun-synchronous orbit.[1][2][3][4][5]
