After the SLS Core Stage hot fire test that aborted just over a minute into the test, it was uncertain what objectives were met and if they would need to do a second test fire. During the second press conference Tuesday afternoon, concerns arose about the Core Stage reaching its cryo-cycling limit before the launch but today NASA shares the Core Stage and Artemis 1 timeline may be in better shape than first thought.

NASA released a statement this week detailing information about some of the findings that contributed to the early shutdown of the Artemis 1 Core Stage during the Green Run Hot Fire test on Saturday. The test was originally supposed to last about 8 minutes, but ended up only lasting 67.2 seconds, far short of the minimum amount of time needed to certify the core.

NASA is returning astronauts to the Moon for the first time since the Apollo program ended in the 1970s, but first the space agency must develop a new rocket capable of reaching lunar orbit. Space Launch System is that rocket, and it’s been in development for several years.

Over the weekend, NASA’s Stennis Space Center in South Mississippi conducted a critical engine test on the core stage of Space Launch System and its four RS-25 engines. While these engines aren’t new — they actually date back to use on the space shuttle — but being configured on a rocket to the Moon is untested.

The epic engine test wasn’t a total success, however, as the vehicle detected an anomaly and stopped firing its engines well before the required test duration. The good news is NASA says both the rocket core stage and its engines remain in good shape.

Signed on the 45th anniversary of the final crewed mission to the Moon, Space Policy Directive 1 directed NASA to begin a mission to send the next man and first woman to the Moon with a pathway to continue onto the crewed exploration of Mars. Since then, the Artemis program has expanded to include already existing programs as well as new commercialized contracts for new services.

This Saturday NASA and their contractors are planning on conducting the final Green Run test for NASA’s Artemis-1 core stage of the Space Launch System rocket. This will be the only time the stage will be fired for a full 8 minutes before its flight.

Originally planned to be a part of the first iteration of Space Launch System, the Exploration Upper Stage (EUS) is set to start being used on the SLS Block 1B variant of NASA’s Moon rocket. Boeing, the prime contractor for NASA’s SLS, announced this week that they have completed a critical design review for the new upper stage of the rocket.

After a few weeks of trial and error, NASA says it has completed the wet dress rehearsal test step for the core stage of Space Launch System, the agency’s rocket to the Moon and beyond. This is the final step before NASA and Boeing engineers fire the core stage in place for eight minutes to collect data.
