The promise of RDREs is that they can move a spacecraft faster and more efficiently, allowing them to carry heavier payloads and travel farther distances than conventional rockets.

I mentioned it was 41-C that originally was STS-13, and my friend Jim Beggs, who was the administrator of NASA, had triskaidekaphobia, and he said, 'There's not going to be [another] Apollo 13 or a Shuttle 13, so come up with a new numbering system.'

NASA has 30 days to kick off a program for a mid-power space reactor ready for launch by 2030. A lunar variant is required, as is an option for nuclear electric propulsion.
