New Delhi: The Indian Space Research Organisation (ISRO) adds another feather in its cap as it embarks on its longest-ever PSLV rocket launch mission today September 26.

In its first multi-orbital launch, India’s workhorse Polar Satellite Launch Vehicle (PSLV-C35) on Monday injects eight different satellites, including the Indian weather satellite SCATSAT-1, into two different orbits.

At 9.12 a:m today, the PSLV-C35 carrying the 371 kg SCATSAT-1 along with seven other satellites, including from the US and Canada, blast off from the first launch pad of Satish Dhawan Space Centre SHAR, Sriharikota.

The total weight of all the eight satellites onboard PSLV C-35 is about 675 kg, ISRO said.

The mission slated to carry out for two hours and fifteen minutes or more is the longest PSLV satellite launch mission of ISRO so far.

About 17 minutes into the launch, PSLV rocket will put its main cargo SCATSAT-1 – for ocean and weather related studies – into a 730 km polar sun synchronous orbit, the rest will be injected into a lower orbit of 689 km after around two hours.

The mission objectives of SCATSAT-1 are to help provide weather forecasting services to the user communities through the generation of wind vector products for weather forecasting, cyclone detection and tracking, ISRO said.

SCATSAT-1 is a continuity mission for scatterometer payload carried by the earlier Oceansat-2 satellite.

Besides SCATSAT-1, the others 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 USA and Canada, respectively.

The 48-and-a-half-hour countdown for PSLV-C35/SCATSAT-1 Mission started at 8:42 a:m on Saturday.

According to ISRO, this will be the 15th flight of PSLV in ‘XL’ configuration with the use of solid strap-on motors.
