NASA is preparing to send the first woman and next man to the Moon in this decade with the Artemis program. Our return to the Moon won’t be like the Apollo program, however, as NASA wants to return in a sustainable fashion: lunar orbit station called gateway, Moon base called Artemis Base Camp, and international partnerships.

The agency briefly paused a critical step in testing the core stage of its new Space Launch System rocket at Stennis Space Center this week. NASA now says it will resume what’s called the wet dress rehearsal test next week. Launching NASA’s Space Launch System rocket and sending the Orion spacecraft around the Moon next year on the Artemis I mission is key to pushing forward with the Artemis program.

The team at the space center in South Mississippi briefly suspended fueling the rocket core stage on Monday after liquid oxygen temperature readings outside of the expected range were detected. Officials described the issue as operational and not caused by the rocket core stage. Now the team believes it has readjusted its fueling procedure to hit the target LOX delivery temperature.

Here’s the latest from NASA’s Artemis blog:

NASA conducted a readiness review from the teams at Stennis Space Center before the long-awaited Green Run Wet Dress Rehearsal (WDR) for Space Launch System’s core stage. The teams are all “Go” to begin the seventh and final test before teams ignite the four RS-25 engines (former Space Shuttle main engines) for a full duration burn strapped into the B-2 test stand in South Mississippi near Interstate-10 and the Louisiana state line.

Ultimately, the Wet Dress Rehearsal marks one of a few preliminary steps remaining before NASA launches its Artemis I mission in November 2021. Artemis I will be the first flight of Space Launch System, in which NASA’s new rocket sends its Orion spacecraft around the Moon for a lunar flyby mission. Artemis II will introduce astronauts to the lunar flyby route, and Artemis III will deliver the first woman and next man to the Moon.
