EROS A1 (Earth Resources Observation Satellite) is an Israeli photo-reconnaissance satellite that was launched by a START 1 rocket from the new launch site at Svobodni in Siberia at 12:30 UT. (It is the third launch from that site. The START 1 rocket is a modified RS-12M Topol ICBM, also known in NATO as SS-25.) The 250 kg (dry mass) triaxially stabilized spacecraft carries a black and white high resolution (1.8 m) CCD camera, to obtain images (with terrain width of 12.6 km) of locations chosen by Israeli military or world-wide commercial clients, and downlink them at one of the 14 ground stations.
