MIMOSA (Micromeasurements of Satellite Acceleration), COSPAR 2003-031B, was a Czech scientific microsatellite. The satellite was nearly spherical with 28 sides and carried a microaccelerometer (MACEK) to monitor the atmospheric density profile by sensing the atmospheric drag on the approximated sphere.
MIMOSA was launched on 30 June 2003, alongside other miniature satellites including MOST and several CubeSat-based satellites. It was delivered to an 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 in the atmosphere on 11 December 2011.
