U.S. Targets 500kW Moon Nuclear Reactor by 2030; Aims To Power Future Space Missions

NASA could place a powerful 500-kilowatt-electric (kWe) nuclear reactor on the Moon by the end of 2030, as part of a bold, high-stakes move aimed at securing long-term U.S. energy dominance in space.

The system, developed under the space agency’s Fission Surface Power Initiative, would represent a significant leap beyond the radioisotope generators that have powered missions like Voyager 1 and Voyager 2, and the Mars rovers for decades.

According to NASA, in comparison to smaller systems, a 500-kWe reactor could continuously power lunar habitats, industrial equipment, communication arrays and even resource extraction operations.

“It might sound like science fiction, but it’s not,” Sebastian Corbisiero, the Space Reactor Initiative national technical director, explained. “It is very realistic and can significantly boost what humans can do in space because fission reactors provide a step increase in the amount of available power.

Robinhood Stock Plunges As Company’s Q4 Revenue Misses Wall Street Estimates

Robinhood (HOOD) stock tumbled more than 12% in early trading on Wednesday after the trading platform's revenue came in below expectations the previous day.

Robinhood posted record revenue of $4.5 billion in 2025, including a record $1.28 billion in the fourth quarter. However, its fourth quarter revenue came in lower than the $1.35 billion expected by the Street.

Crypto revenue for the fourth quarter came in at $221 million, below estimates of $248.2 million. Options revenue also came in short of expectations, at $314 million versus estimates for $331 million.

"A top-line miss is not helpful at all," Christian Bolu, an analyst at Autonomous Research, told Yahoo Finance.

"Net deposit growth decelerated in the fourth quarter and looks like it decelerated in January," he added. "The stock reaction might be warranted here given high expectations and a very expensive stock."

SpaceX’s Next-Gen Super Heavy Booster Aces Four Days of “Cryoproof” Testing

The upgraded Super Heavy booster slated to launch SpaceX’s next Starship flight has completed cryogenic proof testing, clearing a hurdle that resulted in the destruction of the company’s previous booster.

SpaceX announced the milestone in a social media post Tuesday. 

Ground teams at Starbase, Texas, rolled the 237-foot-tall (72.3-meter) stainless-steel booster out of its factory and transported it a few miles away to Massey’s Test Site last week. 

The test crew first performed a pressure test on the rocket at ambient temperatures, then loaded super-cold liquid nitrogen into the rocket four times over six days, putting the booster through repeated thermal and pressurization cycles. The nitrogen is a stand-in for the cryogenic methane and liquid oxygen that will fill the booster’s propellant tanks on launch day.

The proof test is notable because it moves engineers closer to launching the first test flight of an upgraded version of SpaceX’s mega-rocket named Starship V3, or Block 3. SpaceX launched the previous version, Starship V2, five times last year, but the first three test flights failed. The last two flights achieved SpaceX’s goals, and the company moved on to V3.
