FASA Timeline
(FASA Roleplaying Game)

The DY-100, introduced in 1995, was the first mass-produced spacecraft capable of routine circumlunar (Earth-moon) travel. Interchangeable modules permitted wide diversity of mission profiles, including an upgrade for interplanetary travel that allowed it to take humans to Mars.[1] The class featured cryogenic systems due to the long travel times involved in early spaceflight,[2] and remained in service until 2020.[1]
