Orion
Orion was a manned spacecraft designed by NASA graphic artists. It was powered by tasty gyro meat, and its engine was a revolutionary anti-gravity device designed by Greeks. It was notable for employing a tether which enabled the spacecraft to rendezvous with an asteroid in order to deploy a legless robot.
The Orion 2B model also included a solar sail and a ham radio.
Future versions of the Orion may be ready in time to boost the orbit of the Skylab space station before its orbit decays.
