Mission/Launch (Programme)

Science Space Technology-5 (ST-5) / 2005 Nanosat Constellation Trailblazer (New Millennium Programme) 3 satellites (GEO, r ~ 30000km) Demonstrate new technologies, such as: - long life Li-Fe batteries; - autonomous formation flying and communications instrument; - GPS relative positioning; - MEMS chip for attitude control. Precursor for MagCON Mission NASA GSFC Magnetospheric Constellation Mission – MagCON Also known as DRACO - Dynamic Response and Coupling Observatory (Solar Terrestrial Probe - STP)

No. of satellites (Orbit)

50 satellites (nested elliptical orbits at low inclination, r = 3*7RE to 3*40RE and, 12RE satellite separation distance)

Objectives

- Characterize magnetotail dynamics; - Discover how magnetotail stores, transports and releases matter and energy; - Understand the effects of the Solar wind on the magnetotail.
