Artemis 2 Launch Vehicle Returns to Launch Pad
NASA's Artemis 2 launch vehicle and spacecraft have returned to Launch Complex 39B, with a potential launch date set for as early as April 1, 2024. The mobile launch platform, which carries the Space Launch System (SLS) rocket and Orion spacecraft, left the Vehicle Assembly Building at 12:20 a.m. Eastern on March 20, delayed by high winds. After an 11-hour journey, it arrived at the launch pad, marking a significant step in the Artemis lunar exploration initiative.
The Artemis 2 mission initially rolled out to the pad on January 17 and underwent two fueling tests, known as wet dress rehearsals. However, following a planned launch date of March 6, NASA announced on February 21 that the rocket would return to the Vehicle Assembly Building to address a helium blockage in the upper stage. Engineers identified the issue as a dislodged seal in a quick-disconnect line. After a flight readiness review on March 12, NASA approved the vehicle's return to the launch pad, confident that the seal issues causing hydrogen leaks during earlier tests had been resolved.
Launch Windows and Future Plans
NASA has established two-hour launch windows from April 1 to April 6, with the first window opening at 6:24 p.m. Eastern on April 1. However, operational limitations will restrict the agency to four launch attempts during this six-day period. Should these opportunities be missed, the next available launch window is on April 30, with additional opportunities extending into May yet to be disclosed.
In addition to the immediate preparations for Artemis 2, NASA is revising later phases of the Artemis program. On February 27, the agency announced plans to add an SLS/Orion mission in low Earth orbit in 2027, aimed at testing operations with lunar landers being developed by Blue Origin and SpaceX. The first lunar landings are scheduled for early 2028 with Artemis 4 and late 2028 with Artemis 5.
Changes to Upper Stage Development
In a significant shift, NASA has decided to discontinue the development of the Exploration Upper Stage, which was intended for SLS launches starting with Artemis 4. Instead, the agency will procure and modify Centaur upper stages from United Launch Alliance for the upcoming Artemis missions. Further details regarding these changes are expected to be revealed soon.
Official Statements & Responses
At a March 19 press conference, Josef Aschbacher, director general of the European Space Agency, expressed enthusiasm for the upcoming updates from NASA regarding the Artemis program, stating, “ESA will be present, and we really look forward to the updates from NASA on what their plans are within the Artemis context.”
What's Next
The Artemis Suppliers Conference, scheduled for March 23-25, will bring together industry representatives involved in exploration programs, providing a platform for discussions on the future of the Artemis initiative and its international collaborations.
