Description:

• Mayak ("beacon") is a 3U cubesat from Moscow Polytechnic University. It was designed to deploy a highly reflective structure about 2m across which would act as a drag brake but also as an optical beacon.
  The intent was that Mayak will be one of the brightest objects in the night sky; different calculations put the maximum brightness in the mag -5 to mag -10 range; however, the reflector failed to deploy.
