India’s Space Agency Enters Select Group by Launching PSLV-C35 places SCATSAT-1, 8 Satellites In Two Orbits

Chennai, India – 26th September 2016. Indian Space Research Organisation (ISRO) has successfully launched its weather and ocean satellite SCATSAT-1 with seven other satellites.


SCATSAT-1, weighing 371 kg, is the continuance of Oceansat-2 scatterometer mission that aims to provide wind vector data products for weather forecasting, tracking services, and cyclone detection to the users.

From the total of eight satellites, five among them came from foreign countries, while the rest are domestic satellites.

Other counties that participated in this spectacular mission are the US with its commercial high resolution imaging satellite Pathfinder-1; Canada with its NLS-19, technology demonstration satellite; and Algeria with its earth observation satellite ALSAT-1B, remote sensing satellite ALSAT-2B, and technology demonstrator ALSAT-1N. These satellites are commercial payloads included in this mission.

Two of the domestic satellites were made by Indian universities. PISAT was designed by PES University to explore remote sensing applications. Meanwhile, PRATHAM was designed by IIT Bombay to predict the amount of electron in space.

These satellites were launched at 9.12 a.m. this morning from Sriharikota rocket port in Andhra Pradesh by using Polar Satellite Launch Vehicle (PSLV) rocket. They are placed into two orbits with a 670 km polar orbit.

The launch lasted for over 135 minutes. It was the longest launch that ISRO has ever done. Before today’s launching, this mission had faced several obstacles, including bringing together the entire mission in 25 days. And since the satellites had to be put into two different orbits, the PSLV-C35 needed to be re-ignited after the initial placing.

Although launching multiple satellites with a single rocket has ever been done by ISRO when it successfully injected six Singaporean satellites on 16th December 2015, ejecting out several satellites into two different orbits is something new and challenging for ISRO.

“This is a challenging two-in-one mission which puts India in a unique league of nations having the capability to achieve two different orbits in a single mission,” said ISRO Chairman, AS Kiran Kumar.

This mission will function for around 5 years.

Until today, India has launched 79 satellites for international customers.
