PongSat
PongSats are high-altitude near space missions that hold a probe or other project that can fit inside a ping-pong (table tennis) ball. The launch program is run by a volunteer organization, JP Aerospace (which also provided balloon launch services for the Space Chair.) JP Aerospace succeeded in its first launch of PongSat missions, with a balloon-launched rocket (AKA a rockoon), at the West Texas Spaceport near Fort Stockton, in October 2002.
