The (PSLV-C56) also placed seven satellites developed by DSTA, ST Engineering, our universities and private industry into orbit. To bold new frontiers in the space partnership!"

In a dedicated commercial mission, ISRO's workhorse launch vehicle PSLV-C56 on Sunday successfully launched seven Singapore satellites, including the primary payload DS-SAR, a Radar Imaging Earth Observation satellite, from the spaceport of SHAR Range, in Andhra Pradesh's Sriharikota.

"PSLV-C56/DS-SAR Mission fully accomplished," ISRO said.

After a 25.5-hour countdown, the 44.4 m tall four-stage vehicle with a lift off mass of 228 tonnes, took off majestically from the First Launch Pad at 0630 hrs.

PSLV-C56/DS-SAR, is the dedicated commercial mission of NewSpace India Limited (NSIL) for ST Engineering, Singapore.

The launch was conducted by ISRO under a contract with New Space India Limited (NSIL).

After a flight duration of about 25 minutes, all seven satellites had to be injected into orbit.

After a flight duration of 21 minutes, according to the mission plan, PSLV-C56 had to first launch the primary payload, DS-SAR, a 360 kg Radar Imaging Earth Observation satellite into a Near-equatorial Orbit (NEO) at 5 deg inclination and 535 km altitude.

All seven satellites were successfully deployed into their intended orbit, achieving the mission's objectives approximately 20 minutes after liftoff.
