  skos:definition """The MIDAS 2 (Missile Defense Alarm System) satellite was an earth-orbiting
satellite designed to measure IR background and define IR sources.  In
addition, the satellite carried experiments to measure cosmic radiation,
atmospheric density, thermal emission and reflected solar radiation from the
earth, and micrometeorites.  A plasma probe was included too.   The spacecraft
was chemical-battery powered.  IR radiation data were received for the lifetime
of the battery pack, which powered the final transmission on May 26, 1960.
