NASA announced that it would delay plans to land four astronauts on the Moon over safety concerns.
ADVERTISEMENTNASA's plans to fly to the moon and land astronauts on it will be delayed.
The US space agency had planned to send four astronauts around the moon late this year but pushed the flight to September 2025.
The first human Moon landing in more than 50 years also got bumped from 2025 to September 2026.
NASA cited safety concerns with its spacecraft, as well as development issues with the moonsuits and landers coming from private industry.
"Safety is our top priority," said NASA Administrator Bill Nelson. The delays will "give Artemis teams more time to work through the challenges".
The news came barely an hour after a private US company abandoned its attempt to land its spacecraft on the Moon because of a mission-ending fuel leak.
Astrobotic Technology’s lander began losing fuel soon after Monday’s launch, possibly because of a ruptured tank.
The spacecraft had trouble keeping its solar panel pointed towards the sun and generating solar power, as flight controllers scrambled to salvage what they could of the mission.
A Houston company will give it a shot with its own lander next month.
NASA relying on private companies
NASA is relying heavily on private companies for its Artemis Moon-landing programme for astronauts, named after the mythological twin sister of Apollo.
SpaceX’s Starship mega rocket will be needed to get the first Artemis moonwalkers from lunar orbit down to the surface and back up.
But the nearly 121-metre rocket has launched from Texas only twice, exploding both times over the Gulf of Mexico. A third test flight is planned for February.
The longer it takes to get Starship into orbit around Earth, first with satellites and then crews, the longer NASA will have to wait to attempt its first Moon landing with astronauts since 1972.
During NASA's Apollo era, 12 astronauts walked on the Moon. The competition back then was the Soviet Union; now it's China.
Nelson told reporters he's not worried that China will beat America to the Moon with a crew, even with the latest delay. Even so, "we don't fly until it's ready," he stressed.
The US Government Accountability Office warned in November that NASA was likely looking at 2027 for its first astronaut Moon landing, citing Elon Musk’s Starship as one of the many technical challenges.
Another potential hurdle is the development of moonwalking suits by Houston’s Axiom Space.
"We need them all to be ready and all to be successful in order for that very complicated mission to come together," said Amit Kshatriya, NASA's deputy associate administrator.
ADVERTISEMENTHe added that even with the delay, a 2026 Moon landing represents "a very aggressive schedule".
Only one successful Artemis flight so far
NASA has only one Artemis moonshot under its belt so far. In a test flight of its new Moon rocket in 2022, the space agency sent an empty Orion capsule into lunar orbit and returned it to Earth.
To engineers' surprise, some charred material came off the capsule's heat shield during reentry.
Later, testing of another capsule uncovered a design flaw in the life-support electronics, and separate battery issues popped up.
It’s the same kind of capsule that will carry astronauts to and from the Moon, linking up with Starship in lunar orbit for the trip down to the surface and back up.
ADVERTISEMENTStarship will need to fill up its fuel tank in orbit around Earth, before heading to the Moon; SpaceX estimates an estimated 10 fuel transfers will be needed.
The company plans an orbiting fuel depot to handle the job, another key aspect of the program yet to be demonstrated.
NASA's Moon-landing effort has been delayed repeatedly over the past decade, adding billions of dollars to the cost. Government audits project the total programme costs at $93 billion (€84.9 billion) through 2025.
