This is the first major agency effort by the interim NASA administrator, who is also the Transportation secretary and a former Fox News host.

NASA's acting administrator Sean Duffy plans to accelerate the construction of a nuclear reactor that could be used on the moon and alter the way NASA will partner with industry to replace the aging International Space Station.

The acceleration of nuclear development is part of the Trump administration’s efforts to focus NASA on human spaceflight. A reactor would be useful for long-term stays on the moon.
