Pressure Mounts to Cancel NASA's SLS and Orion Programs

The pressure to fix the issues with NASA's Space Launch System (SLS) rocket and Orion spacecraft is building, as repeated technical problems have plagued the Artemis missions. If there are more delays or failures during the upcoming Artemis 2 launch attempts, it could ultimately lead to the cancellation of the SLS and Orion programs.

Why it matters

The SLS and Orion are central to NASA's Artemis program, which aims to return humans to the Moon. Repeated failures and delays with these critical systems could jeopardize the entire Artemis program and NASA's long-term goals for lunar exploration.

The details

The Artemis 1 mission was plagued by a series of technical issues, including hydrogen and helium leaks, that resulted in six failed wet dress rehearsals and scrubbed launches. The same problems have continued into the Artemis 2 preparations, with a new helium flow issue emerging in February 2026. If there are one or two more major problems or long repair timelines, it could lead to the cancellation of the SLS and Orion programs.

• The Artemis 1 mission experienced 6 failed wet dress rehearsals and scrubbed launches in 2022.
• The Artemis 2 mission has already faced 2 failed wet dress rehearsals or scrubbed launches as of February 2026.
• A new helium flow issue emerged on February 20-21, 2026, repeating a similar problem from Artemis 1.
• The vehicle is scheduled to be rolled back to the Vehicle Assembly Building beginning on February 25, 2026 to address the latest issue.
• The earliest realistic launch window is now April 1-6 or April 30, 2026, if the fix is straightforward.

What’s next

If there are one or two more major problems or long repair timelines with the Artemis 2 mission, it could lead to the cancellation of the SLS and Orion programs.
