Welcome to Edition 8.35 of the Rocket Report! The headlines this week are again dominated by the big changes afoot in NASA's exploration program, with the announcement of a Moon base and a nuclear-powered rocket to Mars. The shakeups come as the agency is just a week away from launching Artemis II, a circumlunar flight carrying a crew of four around the Moon. The Ars space team will be writing extensively about this mission in the days ahead, and we may skip the Rocket Report next week to focus on our Artemis II coverage.

NASA announces nuclear rocket demo. NASA's announcement Tuesday that it will "pause" work on a lunar space station and focus on building a surface base on the Moon was no big surprise to anyone paying attention to the Trump administration’s space policy. But what should NASA do with hardware already built for the Gateway outpost? NASA spent close to $4.5 billion on developing a human-tended complex in orbit around the Moon since the Gateway program’s official start in 2019. There are pieces of the station undergoing construction and testing in factories scattered around the world. The centerpiece of Gateway, called the Power and Propulsion Element, is closest to being ready for launch. NASA’s rejigged exploration roadmap, revealed Tuesday in an all-day event at NASA headquarters in Washington, calls for repurposing the core module for a nuclear-electric propulsion demonstration in deep space, Ars reports.
