Now that Artemis II is all wrapped up, NASA has begun its post-game efficiency analyses of all of the methods that labored collectively to get 4 astronauts safely to the moon and again earlier this month. Along with taking people farther than ever earlier than, Artemis II served as an important check flight for upcoming crewed missions which might be deliberate for as quickly as 2027 and 2028, the latter being NASA's bold goal for touchdown astronauts on the lunar floor. To this point, the Orion spacecraft and the SLS rocket appear to have fared fairly nicely.
NASA says its preliminary assessments of the crew capsule present its warmth defend "carried out as anticipated, with no uncommon circumstances recognized," and it didn't exhibit as a lot char loss as seen within the uncrewed Artemis I check. (Navy divers snapped some actually cool footage of the warmth defend underwater after splashdown, as seen under). Splashdown went based on plan, with Orion touchdown 2.9 miles from its focused touchdown website, based on NASA, and its entry interface velocity "was inside one mile-per-hour of predictions."
US NavyNASA says the SLS rocket carried out nicely, too. It nonetheless has exams to run, however, "At most important engine cutoff, when the core stage’s RS-25 liquid engines shutdown, the spacecraft was touring at over 18,000 miles per hour, attaining its insertion velocity for orbit, and executing a exact bullseye for its meant location," the area company famous in a weblog publish.
One factor that we all know did trigger some points, although, was the bathroom system. Shortly after launch, the astronauts reported issues with the urine vent line, which mission specialist Christina Koch was capable of troubleshoot with assist from the bottom crew. However, everybody wish to keep away from that on the subsequent mission, so NASA now has groups testing the {hardware} and information to determine what went improper and learn how to forestall it.
Watch the Earthset
The Artemis II astronauts have continued to share glimpses into their journey across the moon, and this week, the mission's commander, Reid Wiseman posted an unbelievable video of the Earth setting behind the moon, as seen from the Orion spacecraft. People haven't seen that phenomenon firsthand in over 50 years, because the final Apollo mission. Learn extra about that right here.
Just one probability on this lifetime…
Like watching sundown on the seaside from probably the most international seat within the cosmos, I couldn’t resist a mobile phone video of Earthset. You possibly can hear the shutter on the Nikon as @Astro_Christina is hammering away on 3-shot brackets and capturing these… pic.twitter.com/8aWnaFJ69c— Reid Wiseman (@astro_reid) April 19, 2026
Whereas ten days may not look like that lengthy of a time to be in area, it nonetheless does issues to the physique, and returning to Earth has been a little bit of an adjustment for the crew. Astronaut Koch final week posted a video of herself struggling by way of a tandem stroll train together with her eyes closed, taken after her return to Earth. "When folks stay in microgravity, the methods in our physique which have developed to inform our brains how we’re transferring, the vestibular organs, don’t work appropriately," she defined within the caption. "Our brains study to disregard these indicators and so once we first get again to gravity, we’re closely reliant on our eyes to orient ourselves visually."
