ISRO raises the bar, 37th PSLV launches SCATSAT-18, 7 other satellites in 2 orbits

The Indian Space Research Organisation (ISRO) has successfully launched the PSLV C-35 on 26 September for ocean, weather studies in Sriharikota.

The PSLV C-35 carries the 371-kg SCATSAT-1, along with seven other satellites, three from India, three from Algeria and one each from the United States and Canada.

SCATSAT-1 was released first into a 730 km Polar Sunsynchronous Orbit (SSO) within 17 minutes of the launch, followed by the launch of the other satellites into a lower orbit of 689 km, two hours later.

This is India's first-ever multi-orbital launch. The satellites will be injected into two orbits. The multi-orbital launch is believed to be challenging and most of the countries opt to launch their satellites in single orbit.

Prime Minister Narendra Modi congratulated ISRO on successful launch of PSLV-C35/SCATSAT-1 and tweeted "Our space scientists keep scripting history. Their innovative zeal has touched lives of 125 crore Indians & made India proud worldwide."

The total weight of all the eight satellites on-board PSLV C35 is about 675 kg, ISRO said.

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 8:42am on Saturday.

According to ISRO, this is the first mission of PSLV in which it will be launching its payloads into two different orbits.

This will be the 15th flight of PSLV in 'XL' configuration with the use of solid strap-on motors, it added.

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, ISRO added.
