The PSLV (Polar Satellite Launch Vehicle) rocket orbited the French "Spot 6” commercial Earth imaging satellite and the student-built "Proiteres” microsatellite for the Osaka Institute of Technology in Japan. The Spot 6 satellite will collect high-resolution imagery, resolving objects as small as 1.5 meters. Spot 6 was built by Astrium Satellites of France.
