NASA seeks proposals for small cube-shaped satellites

NASA is seeking proposals for small satellite payloads to fly on rockets planned to launch between 2012 and 2014.

These miniature spacecraft, known as CubeSats, could be auxiliary payload on previously planned missions.

A class of research spacecraft called nanosatellites, CubeSats are cube-shaped satellites approximately four inches long, have a volume of about one quart and weigh less than three pounds.

Applicants must submit proposals electronically by 4:30pm EST on 14 November 2011, after which NASA will select the payloads by 30 January 2012.
