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. This is PSLV’s longest flight.
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.

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 A S Kiran Kumar 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,
