ULA's Centaur 5 Selected as New SLS Upper Stage
The Gist
NASA has selected ULA's Centaur 5 as the upper stage for the SLS rocket, starting with Artemis 4.
Explain Like I'm Five
"Imagine NASA is building a giant rocket to go to the moon. They decided to use a part from another rocket, called Centaur 5, because it's already built and works well. This will help them build the moon rocket faster and cheaper!"
Deep Intelligence Analysis
The decision to issue a sole-source contract to ULA underscores NASA's confidence in the Centaur 5's ability to meet the performance requirements of the SLS. NASA's rationale, documented by the Marshall Space Flight Center, highlights the RL10 engine's heritage, the Centaur 5's compatibility with existing infrastructure, and ULA's experience with NASA's Exploration Ground Systems. Furthermore, the Centaur 3's human-rating certification adds to the confidence in the Centaur 5's reliability.
While this move promises to streamline the Artemis program and potentially reduce costs, it also introduces potential risks. Relying on a single supplier could limit innovation and create vulnerabilities in the supply chain. Any delays or technical issues with the Centaur 5 could significantly impact the Artemis program's timeline. Nevertheless, NASA's decision reflects a pragmatic approach to achieving its lunar exploration goals within budgetary and schedule constraints.

- ● Centaur 5 was developed for ULA's Vulcan rocket and has flown four times since January 2024.
- ● The decision aims to reduce complexity and accelerate manufacturing of the SLS.
- ● Centaur 5 leverages the RL10 engine and existing infrastructure at Kennedy Space Center.
- ● Artemis 4 is scheduled to launch no earlier than early 2028.
Optimistic Outlook
The selection of Centaur 5 could lead to faster SLS production and a more reliable launch cadence. Leveraging ULA's existing expertise and hardware may accelerate the Artemis program and reduce overall mission costs.
Pessimistic Outlook
Relying on a sole-source contract with ULA could limit innovation and potentially increase costs in the long run. Any unforeseen issues with the Centaur 5 or ULA's production capabilities could delay the Artemis program.
