FASA Timeline

DY-100 class (TOS 24)

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. The class remained in service until 2020.
