SBIRS GEO 1 (Space Based Infrared System Geosynchronous 1), also known as USA 230, was launched from Cape Canaveral on 07 May 2011 at 18:10 UT by an Atlas 5 rocket. SBIRS GEO 1 is the first dedicated spacecraft to be launched as part of the Space Based Infrared System, or SBIRS. SBIRS is a system of spacecraft that monitor the Earth using infrared sensors in order to detect and track missile launches. Over a period of nine days six critical maneuvers will be conducted to boost the SBIRS GEO 1 satellite into a circular geosynchronous orbit. SBIRS GEO 1 is equipped with both scanning and staring instruments to increase the amount of reconnaissance that can be collected. The scanning instrument on SBIRS satellites will provide global observations, and the staring sensor enables the military to examine a very specific region for emerging threats and fast-moving targets. The satellite features a pair of power-generating solar arrays, two communications antenna wings that unfold and a deployable light shade to shield its sensitive infrared instruments. The SBIRS system will augment and gradually replace the heritage Defense Support Program satellites over the next several years. SBIRS GEO 1 has a design mission life of 12 years.
