The claim: “"Within the next two years, NASA will launch the first-ever nuclear-powered spacecraft to Mars," Trump said. — Fox News, Michael Sinkewicz, Nov. 6, 2026”
Why we rated it this way: Fox accurately quotes remarks Trump delivered November 6 at Kennedy Space Center, and NASA's Space Reactor-1 Freedom page matches the two-year timeline: a fission-powered spacecraft demonstrating nuclear electric propulsion, targeting launch in late 2028 and a Mars flyby to deliver the SkyFall helicopters. NASA's own wording is more precise than "first-ever nuclear-powered." The agency calls SR-1 "humanity's first fission-powered interplanetary spacecraft." NASA's fact sheet on the Multi-Mission Radioisotope Thermoelectric Generator describes that system as a "space nuclear power system" and says an MMRTG powered Curiosity after its November 2011 launch and also powers Perseverance. Those earlier Mars missions used nuclear radioisotope power, not a fission reactor.
See the evidenceWhat would change our rating: NASA documentation that no prior spacecraft sent to Mars used any form of nuclear power, or Fox specifying “first fission-powered” to match NASA’s wording, would move this verdict.

Script
Narration script. If a face or a voice delivers this, the anchor is synthetic.
Morning Check. Fox News says Trump told a Kennedy Space Center audience that NASA will launch the first-ever nuclear-powered spacecraft to Mars within two years. NASA does plan to launch Space Reactor-1 Freedom, a fission-powered Mars mission, in late 2028, but Curiosity and Perseverance already used nuclear radioisotope power. Verdict: missing context.
