NASA plans to launch a nuclear-powered spacecraft to Mars by 2028, a major step for deep space exploration and its planned moon base.

In an on-going overhaul of NASA's Artemis program, agency officials say it will take seven years to build a sophisticated base on the moon.

Missions will include crewed moon landings every six months to visit a permanent lunar base.

"NASA is committed to achieving the near-impossible once again: to return to the moon before the end of President [Donald] Trump's term, build a moon base, establish an enduring p

The new initiative includes a base on the moon, a nuclear-powered flight to Mars and a replacement for the ISS.

NASA announced on Tuesday it has canceled plans to deploy a space station in lunar orbit and will instead use components from the project to build a $20 billion base on the ​moon's surface, while also planning to send a nuclear-powered spacecraft to Mars.

NASA is hitting the reset button on its return to the moon and going even bigger. The agency is fast tracking a permanent base on the moon's surface.

NASA unveiled a new vision for its near-term future Tuesday, including construction of a complete moon base, a major increase in robotic missions and a nuclear-powered spacecraft to bring a slew of
