Artemis II NASA astronauts Victor Glover, Christina Koch, and Reid Wiseman, and CSA (Canadian Space Agency) astronaut Jeremy Hansen recently traveled to Lockheed Martin Space in Littleton, Colorado, where they practiced opening and closing an Orion crew module side hatch model to help demonstrate its reliability and durability during their 10-day mission around the Moon.

During normal mission operations, the crew will not operate the hatches – the ground systems team at NASA’s Kennedy Space Center in Florida will assist the crew into Orion at the launch pad, then close the hatch behind them prior to liftoff. After splashdown in the Pacific Ocean, recovery teams will open the side hatch and help crew to exit.

Back-up crew members Andre Douglas of NASA and Jenni Gibbons of CSA also trained on hatch operations, which help ensure the crew can safely enter and exit the spacecraft in the event of an emergency. The side hatch is normally opened using a manual gearbox system, but in an emergency, the hatch has release mechanisms containing small pyrotechnic (explosive) devices that release the latch pins on the hatch instantaneously, allowing the hatch to open quickly.

Under NASA’s Artemis campaign, the agency will establish the foundation for long-term scientific exploration at the Moon, land the first woman, first person of color, and its first international partner astronaut on the lunar surface, and prepare for human expeditions to Mars for the benefit of all.
