NEXTSat, or Next Generation Satellite and Commodities Spacecraft (NEXTSat/CSC) is an American technology demonstration satellite which was operated as part of the Orbital Express programme. It was used as a target spacecraft for a demonstration of autonomous servicing and refueling operations performed by the ASTRO satellite.[2] Launched in March 2007, it was operated for four months, and then deactivated in orbit.

NEXTSat was launched by United Launch Alliance on an Atlas V 401 rocket; serial number AV-013. The launch occurred at 03:10 UTC on 9 March 2007, from Space Launch Complex 41 at the Cape Canaveral Air Force Station.[3] The launch was contracted by the Space Test Program to launch the STPSat-1 spacecraft, and was named STP-1. It also deployed ASTRO; as well as FalconSAT-3, CFESat and MidSTAR-1.[2] The launch marked the first time United Launch Alliance had launched an Atlas V, the type having previously been operated by International Launch Services.

NEXTSat is a 224-kilogram (494 lb) spacecraft,[2] which was built by Ball Aerospace around the RS-300 satellite bus.[4] It was operated in low Earth orbit; on 9 March 2007, it had a perigee of 490 kilometres (300 mi), an apogee of 498 kilometres (309 mi), 46.0 degrees of inclination, and an orbital period of 94.49 minutes.[5] After completing operations, the ASTRO and NEXTSat spacecraft were separated, and ASTRO performed a separation burn. On 21 July 2007, NEXTSat was deactivated. As of 2007, it was expected to remain in orbit until around 2012.[6]
