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.

Mission highlights

PSLV-C35 was the 37^th launch of the PSLV program. It was also the 102^nd 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 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 Canadian satellite (NLS-19) and one American satellite (Pathfinder-1).
