Quote from the document…
As mentioned in the Introduction, the motivation for selecting NTP as the propulsion system of choice for Mars is simple – it is a proven technology with a specific impulse that is twice that of today’s best chemical rockets.
During the Rover / NERVA programs 1955-1972, a technology readiness level TRL~5-6 was achieved.
Twenty rocket reactors were designed, built and ground tested in integrated reactor/engine tests that demonstrated:
1. A wide range of thrust levels ~25, 50, 75 and 250 klb
2. High temperature carbide-based nuclear fuels that provided hydrogen exhaust temperatures up to 2550 K achieved in Pewee
3. Sustained engine operation – over 62 minutes for a single burn achieved in the NRX-A6, as well as…
4. Accumulated lifetime at full-power, and…
5. Restart capability greater than 2 hours, with 28 startup and shutdown cycles achieved in the NRX-XE experimental engine
…all the requirements needed for a human Mars mission.
