Artemis II toilet malfunctions hours into the historic lunar mission

A toilet malfunction aboard NASA's Orion capsule became one of the first technical challenges of the Artemis II mission, just hours after the crew made history by launching on humanity's first crewed journey toward the Moon in more than 53 years. Mission Specialist Christina Koch reported that the capsule's Waste Collection System had shut itself down during initial orbital systems checks, triggering a blinking orange fault light. She was advised to use a portable contingency bag while ground teams investigated the issue.

The fault indicator appeared despite an otherwise smooth start to the roughly 10-day mission. The four-person crew, comprising Commander Reid Wiseman, Pilot Victor Glover, Koch, and Canadian Space Agency astronaut Jeremy Hansen, lifted off at 6:35 p.m. EDT from Launch Complex 39B at Kennedy Space Center. The astronauts reached orbit and began a planned 25-hour checkout phase in Earth orbit before firing Orion's main engine toward the Moon.

The toilet system represents one of the most significant quality-of-life improvements over earlier crewed spaceflight. During the Apollo missions of the late 1960s and early 1970s, astronauts urinated into adhesive cuffs and defecated into plastic bags in full view of their crewmates. The new system, adapted from waste management equipment used aboard the International Space Station, is housed in a small private compartment fitted with a door and privacy curtains, roughly the size of a restroom on a small commercial aircraft.

Built from titanium, the toilet uses air suction rather than water and gravity to direct waste, with separate collection for liquid and solid material. Urine is vented into space several times daily, while solid waste is stored in containers and returned to Earth. Each astronaut is equipped with a personal funnel attachment for the urine hose to maintain hygiene.

Hansen, on his first spaceflight, highlighted the toilet's importance to crew wellbeing in a Canadian Space Agency vlog last October. He described the compartment as the only place aboard the small spacecraft where crew members can feel genuinely alone, and noted the crew's good fortune in having a toilet with a door.

NASA had anticipated the possibility of a failure. Orion Deputy Program Manager Debbie Korth stated before launch that the crew carried contingency equipment including urine collection bags. She noted that even with the system offline, the crew could still use the toilet for other functions and vent urine overboard as needed.
