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. It has a fairly eccentric orbit, with an initial perigee of 320 km and apogee of 845 km.

MIMOSA was launched alongside other miniature satellites including MOST and several CubeSat-based satellites. Unfortunatelly the satellite never became fully functional due to the several technical problems on board.

Species
and about 400 other species.
Mimosa is a genus of about 400 species of herbs and shrubs, in the subfamily Mimosoideae of the legume family Fabaceae. The most curious plant in the genus is Mimosa pudica or sleeping grass because of the way it folds its leaves down when touched or exposed to heat; many others also fold their leaves in the evening. It is native to southern Mexico, Uruguay and Central America but is widely cultivated elsewhere for its curiosity value, both as an indoor plant in temperate areas, and outdoors in the tropics. Outdoor cultivation has led to weedy invasion in some areas, notably Hawaii.

Members of this genus are among the few plants capable of rapid movement; examples outside of Mimosa include the Telegraph plant, and the Venus Flytrap.

The genus Mimosa has had a tortuous history, having gone through periods of splitting and lumping, ultimately accumulating over 3,000 names, many of which have either been synonymized under other species or transferred to other genera. In part due to these changing circumscriptions, the name "Mimosa" has also been applied to several other related species with similar pinnate or bipinnate leaves but now classified in other genera, most commonly to Albizia julibrissin (Silk Tree) and Acacia dealbata (Silver Wattle).

In Russia, Italy and other countries it is customary to present women with yellow mimosas (among other flowers) on International Women's Day (March 8). This flower is from the Acacia dealbata (Silver Wattle), which is not a true Mimosa.

La Forêt de Mimosa is a song performed in French by Kirsty MacColl about a woman who is murdered by her lover in a Mimosa forest.
