ISRO’s PSLV C-35 today successfully placed eight satellites, in two orbits, making it the space agency’s first multi-orbital mission. The PSLV C-35 lifted off from Sriharikota today, carrying eight satellites. The mission lasted over two hours, making it PSLV’s longest till date. The 44.4 metre tall PSLV rocket blasted off at 9.12 AM and 17 minutes later injected SCATSAT-1 in orbit. The remaining seven satellites were placed in the other orbit from 11:25 to 11:28.

The mission carried India’s weather satellite SCATSAT-1, and seven other satellites from countries including Canada and the US. According to ISRO, the total weight of all the eight satellites onboard the PSLV -C35 was around 675 kg. Tweeting about the launch, Prime Minister Narendra Modi said that it was moment of immense joy and pride for India and congratulated ISRO for the project.

With the launch and the successful placement of the satellites, ISRO scripted history yet again. This is ISRO’s first multi-orbital launch, with the SCATSAT-1 being placed in a 730 km Polar Sunsynchronous orbit and the other seven being placed in 689 km lower orbit. ISRO Chairman AS Kiran Kumar has said that for the purpose of placing satellites in different orbits, there will be will be two re-ignitions of the launch vehicle. For this, ISRO tested its ‘multiple-burn capability’, a new feat for the ISRO.

SCATSAT-1 is the primary satellite of the mission. It is a continuity mission for Oceansat-2 Scatterometer and is meant to provide wind vector data products for weather forecasting, cyclone detection and tracking services. The mission life of the satellite is 5 years, says ISRO. Apart from SCATSAT-1, the satellites that are a part of the mission are; PRATHAM and PISAT, two academic satellites from India; ALSAT-1B, ALSAT-2B and ALSAT-1N (all from Algeria) and Pathfinder-1 and NLS-19, from US and Canada, respectively.
