[b]Progress M-11M deorbited[/b] The Progress M-11M cargo ship completed its solo mission under the 'Radar Progress' mission, aimed at defining the density, particle sizes and reflectivity of the ionosphere environment around the spacecraft, which is caused by the operations of its liquid propellant engines. The retro-fire command was given at 09:34:31 UT. The burn lasted 180 seconds, providing a delta-V of 91.8 meters per second, after which the Progress re-entered the atmosphere and burned up above the pre-set area of the South Pacific. Surviving fragments, if any, came down at 40° 8' southern latitude and 135° 2' western longitude, at 10:21:41 UT.
