The PSLV or 37th Polar Satellite Launch Vehicle, carrying three satellites from India, three from Algeria, and one each from Canada and the US, lifted off from Sriharikota in Andhra Pradesh at 9:12 am. Around noon, ISRO said its launch was "100 per cent successful".  The satellites include SCATSAT-1, a satellite for weather studies, IIT-Bombay’s PRATHAM and PISAT from PES University in Bengaluru. In a first, Indian Space Research Organisation (ISRO)'s PSLV C-35 rocket launched a total of eight satellites, into two different orbits. The Polar Satellite Launch Vehicle(PSLV-C35) carrying the eight satellites took off from Satish Dhawan Space Centre in Sriharikota at 9.12am. Around 17 minutes later, SCATSAT-1, the main payload of PSLV in its 37th flight, was placed in the polar sun synchronous orbit at an altitude of about 730km. SCATSAT-1, which will provide weather forecast including cyclone detection and tracking, will succeed thenow defunct Oceansat-2 satellite launched in 2009. Isro chairman A S Kiran Kumar said SCATSAT-1 would be a stop gap arrangement between Oceansat-1 and Oceansat-2. ISRO said though it had launched several PSLV rockets in the past, this launch is "the first mission of PSLV in which it had launched its payloads into two different orbits," ISRO said.
