NASA Artemis II Crew Begins First 24 Hours Testing Orion After April 1 Launch
After arriving at Kennedy Space Center, the four‑member Artemis II crew — Reid Wiseman, Victor Glover, Christina Koch and Canadian Jeremy Hansen — launched April 1 in NASA’s Space Launch System with the Orion capsule, beginning a roughly 10‑day figure‑eight lunar flyby after a smooth countdown and resolution of earlier fueling and pressurization issues. In the first 24 hours the crew performed an intensive checkout in a highly elliptical Earth orbit to test Orion’s environmental control, life‑support and handling (including a manual flyaround of the spent upper stage), during which flight controllers logged a toilet motor fault and instructed the crew to use contingency urine bags while engineers troubleshoot.
📌 Key Facts
- Artemis II launched successfully from Kennedy Space Center’s Pad 39B on April 1, 2026, lifting off in the evening after a day of countdown and tanking operations.
- The four‑person crew — commander Reid Wiseman, pilot Victor Glover, mission specialist Christina Koch and Canadian astronaut Jeremy Hansen — quarantined in Houston beforehand and boarded Orion for the flight; this is the first crewed Orion mission and SLS’s first crewed flight (second SLS launch overall).
- The mission is a roughly nine‑ to ten‑day lunar flyby/dress rehearsal (a figure‑eight trajectory) that will send the crew farther from Earth than any humans before (about 252,799 miles at the peak), will not enter lunar orbit or land, and is expected to end with a Pacific splashdown around April 10 off Southern California.
- Following ascent and two upper‑stage burns, Orion was placed into a highly elliptical ~24‑hour Earth orbit for on‑orbit testing; the first 24 hours focus on checking environmental control and life‑support systems (CO₂ scrubbing, water, waste/toilet systems) and handling characteristics — flight controllers reported a toilet fault (won’t spin up) and directed the crew to use contingency urine bags while engineers troubleshoot, and pilot Victor Glover manually flew Orion around the spent upper stage to verify handling.
- NASA began loading hundreds of thousands of gallons of cryogenic propellants the morning of April 1 (core stage roughly 537,000 gallons LH2 and 196,000 gallons LOX, plus additional upper‑stage propellant; total propellant loading reported in the ~700,000–760,000‑gallon range) with tanking and a planned terminal count that included a built‑in hold at T‑40 minutes.
- NASA officials said earlier technical issues — including hydrogen leaks and a clogged helium pressurization line that forced a rollback to the Vehicle Assembly Building in February — were repaired and cleared; teams completed an L‑2 review and managers reported being "ready," with launch weather officers forecasting about an 80% chance of favorable conditions and multiple launch opportunities through the first week of April.
- Artemis II is being presented as a historic test and the opening act of a broader Artemis campaign to return humans to the Moon; NASA leaders have reshuffled near‑term plans so Artemis III will serve as a low‑Earth‑orbit lander test and the next crewed lunar landing is now targeted for Artemis IV in 2028.
