NASA's SLS Rocket Future Uncertain After Stage Cancellation
2 Mar
Summary
- NASA must accelerate Orion spacecraft readiness for a mid-2027 launch.
- A new, commercially procured upper stage is needed for the SLS rocket.
- The future of the Lunar Gateway space station is now questionable.
NASA is confronting increased challenges after the recent cancellation of the Exploration Upper Stage, a decision described as a major earthquake for the space community. The agency must now expedite the Orion spacecraft's readiness for a mid-2027 launch and focus on integrating it with lander providers.
The Artemis IV mission will require a human-rated new upper stage for the SLS rocket, as the current upper stage production line is closed. NASA plans to procure this new stage commercially, with the Centaur V reportedly being the likely candidate.
Significant questions remain regarding the future of the Lunar Gateway space station, a key element for lunar ambitions. The cancellation raises concerns about its development, as the Block 1B version of the SLS was intended to launch Gateway modules. NASA has stated that discussions about the Moon base and Gateway will continue in the coming weeks.
