Nuclear Rockets (w. Scooter)
Summary
Hosts Quinn, Chris, and Scooter, joined by guest A. Deceived, explore NASA’s Nerva nuclear rocket program. They detail the technical challenges of nuclear thermal rockets, the successful Kiwi ground tests, and the program’s competent execution. Ultimately, they argue Nerva succeeded technically but was cancelled due to political shifts and budget cuts in the 1970s, rather than engineering failure.
