MIMOSA (Micromeasurements of Satellite Acceleration) is a Czech scientific microsatellite
Miniaturized satellite
Miniaturized satellites or small satellites are artificial satellites of unusually low weights and small sizes, usually under . While all such satellites can be referred to as small satellites, different classifications are used to categorize them based on mass .One reason for miniaturizing...

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
Perigee
Perigee is the point at which an object makes its closest approach to the Earth.. Often the term is used in a broader sense to define the point in an orbit where the orbiting body is closest to the body it orbits. The opposite is the apogee, the farthest or highest point.The Greek prefix "peri"...
of 320 km and apogee of 845 km. As of 23-Nov-2012, atmospheric drag has caused its orbit to become more circularized at 230 km x 296 km. NORAD is predicting it will burn into the atmosphere on 30-Nov-2012.
MIMOSA was launched alongside other miniature satellites including MOST
