Planetary Radio: Space Exploration, Astronomy and Science Artemis update: NASA reshapes the road back to the Moon
Mar 4, 2026
Jared Isaacman, NASA administrator who announced the Artemis reshuffle; Ari Koeppel, AAAS policy fellow focused on tech, workforce and industry impacts; Jack Corelli, Planetary Society government-relations director tracking political drivers. They discuss Artemis II rollback, repurposing Artemis III as a LEO systems test, shifts to standardize SLS and boost launch cadence, reliance on commercial partners, funding and workforce rebuilding.

Episode notes
Artemis II Rollback After Helium Flow Failure
- Lori Glaze described the Artemis II rollback after a wet dress rehearsal when teams found a helium flow no-go to the ICPS RL10 engines.
- Crews rolled the vehicle back to the VAB within days to inspect helium components, replace seals and batteries, and re-close the Orion module.
Standardize SLS And Prioritize Launch Cadence
- Jared Isaacman reframed Artemis to prioritize higher launch cadence and standardized SLS near block one to reduce complexity and regain operational rhythm.
- He tied cadence to safety and workforce muscle memory, aiming for launches closer to 10 months instead of multi-year gaps.
Artemis III Recast As LEO Integrated Systems Test
- NASA will repurpose Artemis III as a low-Earth-orbit rendezvous and integrated systems test rather than an immediate lunar landing.
- The LEO test will exercise Orion-to-lander docking, ECLSS, and possibly X-EVA suit interfaces before attempting a surface landing at Artemis IV.
