NASA’s upcoming Artemis 2 mission, set to launch around April 1, will send four astronauts on a 10-day lunar orbit. This crewed flight marks humanity’s return to the moon since Apollo 17 in 1972, but with a crucial difference: the astronauts will have access to a functional, private bathroom.
From Plastic Bags to a Dedicated Hygiene Bay
The Apollo missions relied on rudimentary waste management. Astronauts used roll-on cuffs for urine and plastic bags for solid waste, often in full view of their crewmates. The Artemis 2 crew – Reid Wiseman, Victor Glover, Christina Koch, and Jeremy Hansen – will enjoy a far more civilized experience. The Orion capsule’s bathroom, though compact, offers a door and even privacy curtains.
This improvement is significant given the limited space within the capsule: 330 cubic feet for four people over ten days. For context, the Apollo capsules were even smaller at 210 cubic feet, holding only three astronauts. The Orion lavatory, built by Lockheed Martin, is roughly the size of a small aircraft restroom.
How it Works: A Modern Space Toilet
The Orion capsule uses a system similar to the Universal Waste Management System (UWMS) found on the International Space Station (ISS). It includes a seat over a canister, with individual urine funnels for hygiene. Unlike Apollo-era designs, this system caters to all genders. While the ISS recycles urine into potable water, Artemis 2 will vent it directly into space due to the mission’s shorter duration.
Solid waste is collected in disposable bags that will be sealed and returned to Earth. The astronauts will need to replace these canisters multiple times during the mission.
Contingency Plans: Back to the Past if Necessary
Despite the advanced design, NASA has prepared for potential malfunctions. If the primary system fails, the crew will revert to Apollo-style urine collection bags as a backup. This illustrates the enduring importance of reliability in space travel, where even basic functions require meticulous planning.
“We’re pretty fortunate as a crew to have a toilet with a door on this tiny spacecraft,” Hansen said in a YouTube video about the Orion bathroom, highlighting the psychological value of even minimal privacy during long-duration missions.
The Artemis 2 mission represents not only a technological leap in lunar exploration but also a substantial improvement in the quality of life for astronauts in deep space. The inclusion of a functional bathroom, however modest, speaks to the evolving priorities of spaceflight: making long-duration missions more sustainable and humane.
