Description
The Icarus, a Mars transfer vehicle designed for The Daedalus Program. The vehicle requires five launches of Block IB Space Launch System rockets. The vehicle is capable of travelling to Mars orbit, dropping a minimum payload of 20,000 kg, and returning to Low Earth Orbit after a 2.4 year journey. On the left end of the vehicle lies the Nuclear Thermal Propulsion segment, consisting of three NTRs that provide an ISP of 990s. On the opposite end of the spacecraft is The Armstrong, the crew lander. Liquid oxygen tank shells from the SLS core stage are used throughout the design of the Icarus. The propulsion stage consists of 6 SLS liquid oxygen tanks, all semi-filled with liquid hydrogen and launched in clusters of 2 by SLS Block IB rockets. The large, main habitat is a dry workshop, using the shell of an SLS liquid oxygen tank. The habitat provides over 24,000 cubic feet of pressurized volume, nearly twice that of Skylab.
