NASA has unveiled a major overhaul of its moon and Mars strategy, scrapping plans for a lunar-orbit space station and instead committing $20bn over the next seven years to build a base on the moon’s surface, while also advancing plans to send a nuclear-powered spacecraft to Mars.
NASA Administrator Jared Isaacman outlined the changes on Tuesday during a meeting in Washington, DC, with partners, contractors and government officials involved in the Artemis programme, saying the agency will increase robotic missions to the moon and lay the groundwork for nuclear power on the lunar surface.
Isaacman, appointed by US President Donald Trump and who took charge in December, said the changes form part of a broader overhaul of NASA’s long-term Moon-to-Mars strategy.
The planned moon base is intended to support long-term human presence on the lunar surface, with robotic missions expected to help prepare the site, test technologies and begin building infrastructure before astronauts return later this decade.
The agency also disclosed plans to launch a spacecraft called Space Reactor 1 Freedom before the end of 2028, a mission designed to demonstrate nuclear electric propulsion in deep space on the way to Mars.
The spacecraft will deliver helicopters on the Red Planet, similar to the Ingenuity robotic test helicopter that flew with NASA’s Perseverance rover, a step the agency said would help move nuclear propulsion technology from laboratory testing to operational space missions.
The Ingenuity helicopter was the first aircraft to achieve powered, controlled flight on another planet. It travelled to Mars attached to NASA’s Perseverance rover and landed in February 2021.
Pausing the Lunar Gateway station
The Lunar Gateway station, a planned space station in lunar orbit being developed with contractors including Northrop Grumman and international partners, was meant to serve as a base where astronauts could live and work before heading to the Moon’s surface.
But NASA now plans to repurpose some Gateway components for use on the surface instead.
Repurposing Lunar Gateway to create a base on the moon’s surface leaves uncertain the future roles of Japan, Canada and the European Space Agency in the Artemis programme, three key NASA partners that had agreed to provide components for the orbital station.
“It should not really surprise anyone that we are pausing Gateway in its current form and focusing on infrastructure that supports sustained operations on the lunar surface,” Isaacman said.
The changes to NASA’s flagship Artemis programme are reshaping billions of dollars’ worth of contracts and come as the United States faces growing competition from China, which is aiming to land astronauts on the moon by 2030.
The Artemis programme, begun in 2017 during Trump’s first term as president, envisions regular lunar missions as NASA’s long-awaited follow-up to its first moon missions in the Apollo programme that ended in 1972.
