Nasa to spend $20bn on moon base after cancelling orbiting station

Nasa is cancelling plans to deploy a space station in lunar orbit and will instead use its components to construct a $20bn base on the Moon’s surface over the next seven years, its new chief, Jared Isaacman, said on Tuesday.Isaacman, who was sworn in at the agency in December, made the announcement at the opening of a daylong event at Nasa’s Washington headquarters at which he outlinedchanges he is making to the agency’s flagship Moon programme Artemis.“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 told delegates at the event.The Lunar Gateway station, largely already built with contractors Northrop Grumman and Lanteris Space Systems, owned by Intuitive Machines, was meant to be a space station parked in a lunar orbit. Repurposing the craft for a lunar surface base is not simple.“Despite some of the very real hardware and schedule challenges, we can repurpose equipment and international partner commitments to support surface and other program objectives,” Isaacman said.Lunar Gateway was designed to serve as both a research platform and a transfer station that astronauts would use to board Moon landers before descending to the lunar surface.The changes imposed by Isaacman on the flagship US Moon programme in recent weeks are reshaping billions of dollars’ worth of contracts under the Artemis effort.That is sending companies scrambling to accommodate the extra urgency as China makes progress toward its own 2030 Moon landing.
