NIMF (Nuclear rocket using Indigenous Martian Fuels) was a monolithic, reusable, crewed Mars Transfer Vehicle, lander, and Earth return vehicle proposed in the 1990s as a follow-on to the Mars Direct architecture. Its principle design feature was the use of a nuclear-thermal rocket engine consuming liquid carbon dioxide as reaction mass, which could be extracted directly from the Martian atmosphere with minimal equipment or electrical power needed. Compared to chemical-propulsion Earth return vehicles using hydrogen or methane, NIMF could refuel up to 100 times faster on the surface due to this lower power requirement, allowing a launch back to orbit in just hours instead of months, and with no pre-placed equipment needed. At the end of its mission, it would aerocapture back into Earth orbit and be refueled for another Mars mission
