NASA on Tuesday added more delays to its Artemis Moon program, scheduling for 2026 its first astronaut lunar landing in half a century while spacecraft from Elon Musk’s SpaceX, Lockheed Martin and other contractors face development challenges.
The US space agency’s first two Artemis missions involving astronauts were each pushed back nearly a year in delays designed “to give the Artemis teams more time to work through the challenges,” NASA administrator Bill Nelson told reporters in a news conference.

FUEL LEAK ON ASTROBOTIC’S MOON LANDER LEAVES “NO CHANCE” OF SOFT LANDING
Astrobotic’s Peregrine lunar lander has “no chance” of a soft landing on the Moon after springing a propellant leak in the first few hours of its journey in space, the company said on Tuesday about the first such US attempt in five decades.
There was 40 hours of fuel left on the lander that will allow it to operate “as a spacecraft” even as engineers determine what its new mission in orbit will be, the space robotics firm said.
The craft was launched aboard the first flight of Vulcan, a rocket that had been under development for a decade by United Launch Alliance, a joint venture of Boeing and Lockheed Martin.
The lander was launched successfully at 2:18am ET on Monday from Cape Canaveral, Florida, but it suffered a propulsion system issue enroute to the Moon.
After the launch, the lander failed to enter its correct sun-facing orientation in space and saw its battery levels plummet, but Astrobotic was able to fix the issue, the company said.
“The team continues to work to find ways to extend Peregrine’s operational life,” it said, adding that engineers are receiving data and proving spaceflight operations for components and software related to its next lunar lander mission.

Artemis 3, the first crewed Moon landing under the program using SpaceX’s Starship, is now scheduled for September, 2026, previously planned for late 2025, NASA said.
The precursor to that Moon landing mission, Artemis 2, was also delayed, now planned for September, 2025, NASA said. Artemis 2 involves four astronauts flying the Lockheed-built Orion capsule around the Moon and back. Reuters reported on Monday the Moon mission delays were imminent.
The new schedule “acknowledges the very real development challenges that have been experienced by our industry partners,” said Amit Kshatriya, head of NASA’s Moon and Mars exploration strategy.
NASA astronauts’ journey to the Moon will be a relay among multiple spacecraft in space, initially launching off Earth aboard Orion then transferring in space to SpaceX’s Starship system to go to and from the lunar surface.
Issues and investigations around Orion’s heat shield, the shell that protects astronauts from the heat of re-entering Earth’s atmosphere, and the spacecraft’s batteries and electrical system are among the reasons for the delays, Kshatriya said.
Orion first launched to space in 2022 without people aboard in NASA’s Artemis 1 mission, which marked the first flight of the agency’s powerful Space Launch System rocket.
SpaceX, though it has been test-launching Starship from Texas, still faces a lengthy to-do list before the craft lands astronauts on the Moon. It must demonstrate it can dock and refuel to other “tanker” Starships in orbit, a process inherent to its design in transporting astronauts anywhere beyond Earth’s orbit.
Kshatriya called those feats “extremely challenging”.
Jessica Jensen, SpaceX’s vice president of customer operations and integration who was also on the call with reporters, downplayed the fuel transfer challenges. SpaceX has demonstrated similar docking events in orbit with its Crew Dragon capsule, Jensen said.
Jensen said roughly 10 Starship launches will be required to fill up the “tanker” Starship that will act as an orbital fuel station. The lander Starship will top off there before putting humans on the Moon.
