In a first, Indian Space Research Organisation (ISRO)’s PSLV C-35 rocket propelled a sum of eight satellites, into two distinct circles. The 371 kg SCATSAT-1, a satellite for climate related studies was put in the polar sun synchronous circle at a height of 730 km around 17 minutes after the rocket took off from Satish Dhawan Space Center at Sriharikota at 9.12 a.m.
Around two hours after it, the rocket put two satellites from instructive organizations (PISAT and PRATHAM), three commercial payloads from Algeria (ALSAT-1B, 2B and 1N) and one each for Canada (NLS-19) and the United States (Pathfinder-1).
Announcing the successful launch of all the satellites from the Mission Control Centre, ISRO chairman A.S. Kiran Kumar said the Monday launch marked a “landmark day” in the history of ISRO.
The rocket was re-ignited off twice amid its flight to put the arrangement of satellites in an alternate circle. Because of the re-ignition, the Monday’s launch is by a wide margin the longest PSLV launch by ISRO.
Though ISRO has launched several PSLV rockets in the past, this launch is “the first mission of PSLV in which it will be launching its payloads into two different orbits,” ISRO said.
SCATSAT-1 with a life of five years, would provide weather forecasting services through the generation of wind vector products.
The 10 kg-measuring PRATHAM by IIT Bombay means to assess the aggregate electron number with a determination of 1km x 1km area matrix and PISAT (5.25 kg) from PES University in Bengaluru expects to investigate remote sensing applications.
ALSAT-1B is an Earth perception satellite (103 kg), ALSAT-2B is a remote detecting satellite (117 kg) and ALSAT-1N (7 kg) is technology demonstrator. NLS-19 is a technology demonstration micro satellite (8 kg) and Pathfinder-1 is a commercial high resolution imaging micro satellite (44 kg).
