MIMOSA
MIMOSA (Micromeasurements of Satellite Acceleration) is a Czech scientific microsatellite. The satellite is nearly spherical with 28 sides and carries a microaccelerometer to monitor the atmospheric density profile by sensing the atmospheric drag on the approximated sphere.

MIMOSA was launched on June 30, 2003 alongside other miniature satellites including MOST and several CubeSat-based satellites. It had a fairly eccentric orbit, with an initial perigee of 320 km (200 mi) and apogee of 845 km (525 mi). The satellite never became fully functional due to several technical problems on board. It is no longer in orbit. NORAD reported it burnt into the atmosphere on December 11, 2011.
