Artemis 1 is almost home, and NASA is readying for the next stages already.
"Artemis 1 and Orion have been phenomenal," Nujoud Merancy, chief of the exploration mission planning office at NASA's Johnson Space Center, told Space.com in a video interview. Orion was tasked with flying around the moon to collect data for future crewed missions and so the mission has been performing so well, with only minor glitches, that NASA felt comfortable adding more tasks to the manifest.
"The whole point [and] purpose of this mission was to validate that we designed the rocket and the spacecraft right, and it's exceeding expectations to the point we were actually adding objectives with Orion," Merancy added.
The primary objective of the Artemis 1 mission will be completing the high-speed re-entry and splashdown, which is so far on track for Sunday (Dec. 11). The mission also achieved other key objectives, such as testing the unflown Space Launch System and flying in a distant retrograde orbit around the moon to assess readiness for human occupancy of the Orion spacecraft.
More analysis will come after splashdown to see how well Orion did, Merancy said. "All of the data recorded during the mission, the engineers and the teams will be going back through it to make sure that it matched our predictions. That's really the forward plan."
When Artemis 2 flies around the moon with astronauts in about 2024, it will be a test of Orion's life support systems as those were not included in Artemis 1. The crew has not yet been announced, but the mission design is already completed, Merancy said.
Following that will be the first crewed landing of the moon, which is expected to be in 2025 or so with Artemis 3, which will begin a series of excursions to the south pole of the moon along with NASA's planned Gateway space station in orbit.
"There's just so much to do," Merancy added of the mission planning, but added that the Artemis team will be taking some time to celebrate the success of Artemis 1 during the splashdown.
"There's going be a viewing party here at Johnson, on Sunday, to watch it happen," Merancy said. "I'll be bringing the family, and we'll be here to celebrate like everyone else."
