Got a good idea for a small satellite? NASA has issued a broad agency announcement seeking low-cost flight demonstration proposals for small satellites, which generally weigh less than 400 pounds and are usually launched as secondary payloads. The NASA Edison SmallSat Demonstration Program says this solicitation will focus on the communications capabilities of these small spacecraft. Executive summaries of these proposals are due no later than March 4, 2012. For more information, visit: www.nasa.gov/oct.
