PSLV-C28

PSLV-C28 (a.k.a. DMC3 mission) was the 29th consecutive successful mission (overall 30th) of the PSLV program. The PSLV-C28 carried and successfully deployed 5 satellites in the Sun-synchronous orbit. With a launch mass of 320000 kg and payload mass of payload mass 1440 kg, the C28 was the heaviest commercial mission undertaken by the Indian Space Research Organisation and Antrix Corporation. The PSLV-C28 carried three identical optical Earth observation satellites (DMC3-1, DMC3-2 & DMC3-3), an optical Earth observation technology demonstrator microsatellite (CBNT-1), and an experimental nanosatellite (De-orbitSail). All the satellites were built by Surrey Satellite Technology (SSTL). Although built by SSTL, the "De-orbitSail" belonged to the Surrey Space Centre.
