ISRO ‘s heaviest commercial mission – To launch 5 UK satellites

The Indian Space Research Organisation (ISRO) is preparing for its heaviest commercial mission (1440 kg) to launch 5 satellites of United Kingdom (UK) into orbit from the Satish Dhawan Space Centre, Sriharikota on July 10.
PSLV-C28 will launch the theee identical DMC3 optical earth observation satellites developed by the Surrey Satellite Technology Limited (SSTL), UK. Each of the DMC3 satellite weighs 447 kg and will be launched into a 647 km Sun-Synchronous Orbit (SSO) with the help of XL version of PSLV.
Moreover, PSLV-C28 will also carry two auxiliary satellites from UK – CBNT-1, a technology demonstrator earth observation micro satellite built by SSTL, and De-OrbitSail, a technology demonstrator nano satellite built by Surrey Space Centre.
The DMC3 constellation, comprising three advanced mini-satellites DMC3-1, DMC3-2 and DMC3-3, is designed to address the need for simultaneous high spatial resolution and high temporal resolution optical Earth Observation.

Launched into a single Low-Earth Orbit plane and phased with a separation of 120 degrees between them, these satellites can image any target on the Earth’s surface every day. Major application areas include surveying the resources on earth and its environment, managing urban infrastructure and monitoring of disasters.

CBNT-1, weighing 91 kg, is an optical Earth Observation technology demonstration micro satellite built by SSTL. The 7 kg De-orbitSail from Surrey Space Centre, is an experimental nano satellite for demonstration of large thin membrane sail and drag deorbiting using this sail.

ISRO’s previous heavy commercial payload mission was SPOT-7, a French satellite weighing 712 kg that a PSLV put in orbit on 30th June, 2014.

PSLV-C28 is expected to blast off at about 10 pm on Friday for which the 62.5-hour countdown will start on July 8 around 7.30 am.

Team Admirable India wishes ISRO best of luck for the upcoming launch. May ISRO bring more and more laurels to the Indian space research community. ISRO is India’s pride, prestige and honour and we are sure there will be another feather in the cap of ISRO after the successful Mars Orbiter Mission.

Jai Hind !

Admirable India
