MIMOSA

For other uses, see Mimosa (disambiguation).

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 to monitor the atmospheric density profile by sensing the atmospheric drag on the approximated sphere.^[1]

MIMOSA was launched on June 30, 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).^[2] The satellite never became fully functional due to several technical problems on board.^[3] It is no longer in orbit. NORAD reported it burnt into the atmosphere on December 11, 2011.^[4]
