Jared Isaacman announced NASA's plan to launch SR-1 Freedom, a 100-kilowatt fission reactor, in 2028, marking a significant step towards nuclear-powered space travel. This mission aims to leverage the lunar South Pole as a proving ground for technologies needed for eventual Mars missions. The SR-1 Freedom mission will also deploy 'Skyfall', carrying three 'Ingenuity' class helicopters to scout subsurface ice and future landing sites.
“In 2028, NASA will leave decades and billions of dollars of failed nuclear programs behind and launch SR-1 Freedom, a 100 kilowatt fission reactor that will finally get America underway on nuclear power.”
“The mission will transit Mars and release Skyfall, which carries three ingenuity class helicopters, and using ground penetrating radar to scout subsurface ice and future landing sites.”
“This will mark the beginning of the nuclear NASA, pivoting our workforce and facilities back to doing the near impossible missions with no obvious business case that no company, no agency, or nation is presently capable of accomplishing, but that extend humanity's reach farther into the outer solar system.”
