NEXTSat, or Next Generation Satellite and Commodities Spacecraft (NEXTSat/CSC) was an American technology demonstration
satellite
A satellite or an artificial satellite is an object, typically a spacecraft, placed into orbit around a celestial body. They have a variety of uses, including communication relay, weather forecasting, navigation ( GPS), broadcasting, scient ...
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.
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
Atlas V is an expendable launch system and the fifth major version in the Atlas (rocket family), Atlas launch vehicle family. It was developed by Lockheed Martin and has been operated by United Launch Alliance (ULA) since 2006. Primarily used to ...
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
Cape Canaveral Space Force Station (CCSFS) is an installation of the United States Space Force's Space Launch Delta 45, located on Cape Canaveral in Brevard County, Florida.

.
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.
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 was a spacecraft,
which was built by
Ball Aerospace around the
RS-300 satellite bus. It was operated in
low Earth orbit
A low Earth orbit (LEO) is an geocentric orbit, orbit around Earth with a orbital period, period of 128 minutes or less (making at least 11.25 orbits per day) and an orbital eccentricity, eccentricity less than 0.25. Most of the artificial object ...
; on 9 March 2007, it had a
perigee of , an
apogee of , 46.0 degrees of
inclination, and an
orbital period
The orbital period (also revolution period) is the amount of time a given astronomical object takes to complete one orbit around another object. In astronomy, it usually applies to planets or asteroids orbiting the Sun, moons orbiting planets ...
of 94.49 minutes.
After completing operations, the ASTRO and NEXTSat spacecraft were separated, and ASTRO performed a separation burn. On 21 July 2007, NEXTSat was deactivated. , it was expected to remain in orbit until around 2012. The satellite decayed from orbit on 21 April 2023.
