Cosmos was a freight and passenger spaceship designed for Earth-Moon-Mars travel. It was the first of the three spaceships of the Tsung fleet designed and built by Tsung Astrofreight. Cosmos was powered by a newly developed experimental technology known as a muon drive. The ship was built at the Imbrium shipyards at Mare Imbrium on the Moon. It was launched on October 4, 2057. The date, which was reffered to as Sputnik Day, commemorated the centennial anniversary of the launch of Sputnik 1, the first artificial Earth satellite.
