On December 16, 2015 at 12:30 UTC the PSLV-C29 (Polar Satellite Launch Vehicle) rocket-carrier was launched from the Satish Dhawan Space Center on Sriharikota Island, India's primary launch site on the country's east coast. The rocket orbited six Singaporean satellites: TeLEOS-1, KR-1, VELOX-CI, VELOX-II, Galassia and Athenoxat-1. The prime satellite is TeLEOS 1, a 400-kilogram commercial Earth imaging observatory made by ST Electronics in Singapore. TeLEOS 1 has a five-year design life, and its orbit will yield regular revisits of observation targets every 12 to 16 hours. The five other spacecraft orbited by the PSLV-C29 rocket included microsatellites and CubeSats.
