NASA Cancels Mobile Launcher 2 Project at Kennedy Space Center

Agency restructures Artemis program, standardizing on SLS Block 1 configuration

Published on Mar. 4, 2026

NASA has announced the cancellation of the Mobile Launcher 2 (ML-2) project at the Kennedy Space Center. The decision comes as part of a broader restructuring of the Artemis program, which will now focus solely on the SLS Block 1 configuration, rendering both ML-2 and the Exploration Upper Stage (EUS) unnecessary.

Why it matters

The cancellation of ML-2 will have a significant impact on the local workforce, with an estimated 300 tradespeople and over 200 small businesses contracted to support the project now facing an uncertain future. It also marks a major shift in launch infrastructure at KSC, which will now rely solely on the existing Mobile Launcher 1 (ML-1) platform.

The details

According to NASA's statement, the agency is standardizing its SLS rocket configuration and adding a new mission to the manifest, all using the SLS Block 1 instead of the Block 1B planned for Artemis IV and beyond. This restructuring has rendered both ML-2 and the EUS surplus to requirements. The cancellation of ML-2 will affect a substantial number of people locally, including welders, ironworkers, carpenters, and electricians who were working on the project.

  • On February 27th, 2026, NASA announced the Artemis program restructuring.
  • On March 3rd, 2026, NASA issued a statement clarifying the decision to cancel the ML-2 project.

What they’re saying

“Yes, there were fixes based on what was observed after Artemis I. We will soon find out if ML-1 is more resilient after Artemis II launches. Regardless, having the team and the resources to turn the pad and meet the target launch cadence is a program necessity.”

— Jared Isaacman, NASA Administrator (Interview with space journalist Marcus House)

What’s next

NASA will focus its efforts on the existing Mobile Launcher 1 (ML-1) platform, making necessary improvements to ensure it can support the target launch cadence for the Artemis program.

The takeaway

The cancellation of the Mobile Launcher 2 (ML-2) project at the Kennedy Space Center is a significant pivot for the Artemis program, reflecting NASA's decision to standardize on the SLS Block 1 configuration. This move will have a substantial impact on the local workforce and contractors, but it also underscores the agency's commitment to streamlining its operations and infrastructure to meet the demands of the Artemis mission manifest.
