Nuclear power is key to NASA’s space plans

Key Points:

• NASA Administrator Jared Isaacman visited Idaho National Laboratory (INL) to discuss collaboration on nuclear energy projects for space exploration, including launching the Space Reactor-1 Freedom (SR-1) to Mars by 2028 and deploying a compact nuclear reactor on the moon by 2030.
• Isaacman emphasized the importance of fission power for sustainable and routine space exploration, envisioning nuclear-powered spacecraft enabling missions to distant destinations like Mars and the outer solar system.
• Several private companies developing small modular reactors (SMRs) showcased their progress, with some designs already addressing NASA and INL technical challenges, highlighting growing public-private partnerships in space nuclear technology.
• Isaacman compared the current nuclear space initiative to the early U.S. Navy nuclear propulsion program, calling for an agency-wide, Apollo-like effort to build a "nuclear NASA" capable of interplanetary exploration.
• The visit inspired local university students studying nuclear and engineering fields, who expressed enthusiasm for NASA's nuclear-powered space ambitions and the potential benefits of space exploration for humanity and Earth.
