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.

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. 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).
