The Orion spacecraft from the Artemis II mission has left Earth's orbit, setting its course for the Moon. This marks the first time in over fifty years that a manned mission has approached our natural satellite.
However, before leaving Earth's orbit, the crew faced an unexpected issue: the spacecraft's toilet malfunctioned.
The translunar injection maneuver, which took five minutes and 49 seconds, required a velocity change of 388 meters per second to allow the capsule to escape Earth's gravitational pull.
With this achievement, the four astronauts aboard—Commander Reid Wiseman, Pilot Victor Glover, Mission Specialist Christina Koch, and Canadian astronaut Jeremy Hansen—became the first humans to venture beyond Earth's orbit since the Apollo 17 mission to the Moon in 1972.
Prior to this historic moment, the mission experienced its first scare: just hours after launch, the toilet on the spacecraft stopped working.
Christina Koch reported the issue to Mission Control: "The toilet has shut down, and I have a flashing amber fault light."
Ground technicians guided the crew to resolve the issue remotely, and the system was restored hours later. Koch led the repair efforts and embraced the nickname she earned during a press conference held on Friday.
"I'm the space plumber. Proud to call myself the space plumber," she said with laughter.
The astronaut explained that the toilet is likely "the most important equipment on board," and the entire crew was relieved to find it was a minor problem.
"Initially, we thought there might be something blocking the motor, but it was fine. It was just a priming issue, having been inactive for too long and needing to warm up. Fortunately, everything is back to normal," she revealed.
Mission Control also celebrated the resolution in their own way.
"We are pleased to inform you that the toilet is ready for use. We recommend allowing the system to reach operating speed before adding any liquid," they advised.
The Orion spacecraft is equipped with a titanium waste management system, an enhanced version of what's used on the International Space Station, which employs an air tube to extract waste: liquids are released into space, while solids are retained for later medical analysis.
After overcoming the setback and completing the translunar injection, NASA Director Jared Isaacman announced on social media that the four astronauts are "on their way to the moon."
Lori Glaze, Interim Associate Administrator of the Exploration Systems Development Mission Directorate, expressed it more solemnly: "For the first time since Apollo 17 in 1972, humans have left Earth's orbit. This is a monumental moment, and we are proud to share it with the world."
Unlike Apollo 17, Artemis II will not land on the Moon. Its mission is to validate Orion's systems with a human crew before the planned lunar landing missions within the program.
The lunar flyby is scheduled for Monday, April 6, when the astronauts will photograph areas of the Moon's far side never before seen directly by humans. They will then return to Earth and splash down in the Pacific Ocean off the coast of San Diego on April 10.
