ISRO’s heaviest commercial payload

Indian Space Research Organisation (ISRO) –  Polar Satellite Launch Vehicle (PSLV) conducted its thirtieth flight from the Satish Dhawan Centre, Sriharikota on July 10 with the heaviest payload ever for a commercial launch.

India has established itself as an efficient commercial launch pad for foreign satellites. This is the heaviest payload for a commercial launch. A successful PSLV-C28 launch would give a big boost to Isro’s commercial launch capabilities.

said Isro spokesman Deviprasad Karnik.

PSLV-C28 launched the UK’s 3 identical optical earth observation satellites- DMC3, built by Surrey Satellite Technology Limited (SSTL), & two technology demonstrator auxiliary satellites into space – the CBNT-1 and De-OrbitSail.

ISRO used the high end XL version of PSLV for the 9th time.The three DMC3 satellites each weighed 447kg & were launched into a 647km sun-synchronous orbit, the CBNT-1 – 9kg micro satellite, & De-OrbitSail, – 7kg nano satellite i.e

a total of 1357 kg !

Isro said on its website that accommodating the three DMC3 satellites each with a height of about 3 metre within the existing payload fairing of PSLV was a challenge.

After the hugely successful Mars Orbiter Mission, which completed 300 days in the Martian orbit a few days back, India is now planning a mission to Venus.
