PSLV-C35 was the successful mission of the Polar Satellite Launch Vehicle program which set eight satellites in space. It was launched on 26 September 2016 by Indian Space Research Organisation (ISRO) from the Satish Dhawan Space Centre at Sriharikota.

Launch

PSLV-C35 was launched at 03:42 hours Coordinated Universal Time (09:12 hours Indian Standard Time) on 26 September 2016 from the first launch pad of Satish Dhawan Space Centre at Sriharikota in the Indian state of Andhra Pradesh.[1][2]

Mission highlights

PSLV-C35 was the 37th launch of the PSLV program. It was also the 102nd overall launch by Indian Space Research Organisation. PSLV-C35 was the first spaceflight by ISRO to place satellites in two different orbits with a single rocket. It carried and injected eight satellites built by India, Algeria, Canada and United States.[1][3][4]

Payload

PSLV-C35 carried and deployed eight satellites in two different orbits in a single mission (Polar and Sun-synchronous orbit). This was the first time India had placed satellites in two orbits in a single mission.[5] The vehicle carried three satellites from India (ScatSat-1, PISat & Pratham), three satellites from Algeria (Alsat-1B, 2B & 1N), one each from Canada (NLS-19) and the United States (Pathfinder-1).[1][3][6]
