- NASA’s next Artemis mission, scheduled to send four astronauts to orbit the moon, has been postponed until 2026, the agency announced.
- The delay also postpones the expected schedule for Artemis’ subsequent mission to land astronauts on the moon.
- NASA Administrator Bill Nelson said that under the new schedule, the United States would land astronauts on the moon before China.
NASA announced Thursday that the next Artemis mission that will send four astronauts around the moon will be delayed until 2026. A program already years behind schedule and billions of dollars over budget has been delayed further.
NASA announced in January that the Artemis II mission would launch in September 2025 instead of late 2024. Now, NASA says it is targeting an April 2026 launch to give it more time to address issues with its next-generation Orion space capsule. The problem was discovered during an unmanned Artemis test flight in 2022.
The delay will also postpone the Artemis III mission, which aims to land astronauts near the moon’s south pole. That mission is planned for mid-2027, rather than launching in September 2026.
NASA Administrator Bill Nelson said the adjusted schedule should still put the United States on track to return astronauts to the moon before China lands its own. .
Nelson said the mid-2027 goal is “much earlier than the Chinese government’s stated intention” to land Chinese astronauts on the moon by 2030.
China’s interest in moon exploration has sparked a new space race of sorts, with some U.S. experts and officials saying that if China reaches the moon’s surface before the United States, There are growing concerns that there may be competition for space resources, which are thought to be water ice. They will be trapped in a permanently shadowed crater at the moon’s south pole. It is believed that water on the moon could be used to make rocket fuel to power missions deep into space.
“Landing on the moon’s south pole is critical to avoid ceding part of the moon’s south pole to China,” Nelson said.
NASA officials attributed the need to delay the Artemis mission to a flaw in the Orion spacecraft’s heat shield that was discovered during the capsule’s uncrewed flight. NASA Deputy Administrator Pam Melroy said, for example, that the researchers noticed that the heat shield was worn in places, with some of the outer layers cracking and peeling off due to internal pressure buildup.
Orion’s heat shield covers the bottom of the capsule and plays a key role in protecting the spacecraft and its potential astronauts from extreme temperatures upon re-entry into Earth’s atmosphere. .
Extensive testing has determined that the Orion capsule’s unique method of returning to Earth likely eroded its heat shield. The spacecraft is designed to perform what’s called a “skip entry,” in which it enters and exits the atmosphere, dissipating energy and slowing it down.
But Melroy said this reentry caused heat to build up inside the outer layer of the heat shield, eventually causing it to crack and wear out in parts.
The delays for Artemis’ next two flights will give engineers time to address these shielding issues and prepare for what Nelson called a “modified approach trajectory.”
“Astronaut safety is always paramount in our decisions. It is our North Star,” Nelson said. “We will not fly until we are confident that we have made the flight as safe as possible for our passengers.”
With the new administration of Donald Trump set to take over the White House in January, some space industry experts are speculating that parts of the Artemis program may be revisited or even scrapped. There is.
But Melroy said the decision to proceed with the Artemis program was “pretty clear” and should not be delayed during the transition period as the incoming administration establishes its goals and priorities.
“We would like to postpone any decisions about starting or ending the program for as long as possible,” Melroy said. “We had to postpone important decisions for our new team and we haven’t had a chance to explain them to anyone since we haven’t yet accepted a transition team.”
NASA has spent more than $42 billion over more than a decade developing the new Space Launch System mega-rocket and Orion spacecraft aimed at bringing astronauts back to the moon. As part of this effort, NASA envisions launching regular missions to set up base camps on the moon before eventually heading to Mars.
