NASA is preparing for its first crewed trip to the Moon in over 50 years. This mission could launch in just two weeks. Next year, NASA aims to send astronauts back to the lunar surface as part of the Artemis 3 mission, raising the stakes even higher.
When stepping out of the spacecraft, astronauts face unique challenges. NASA is currently deciding between offerings from Blue Origin and SpaceX for this element. The Moon’s extreme temperatures, intense radiation, and thin atmosphere make it tough to stay safe. Plus, the bulky spacesuits add another layer of difficulty. These suits could be more exhausting to wear than ones used during spacewalks at the International Space Station.
Former astronaut Kate Rubins, who has spent 300 days in space, shared her concerns about the lunar suit being developed by Axiom Space. This suit is part of a $228 million contract with NASA. At a recent National Academies of Sciences meeting, she highlighted the physical stress that astronauts will face on the Moon, pointing out that they could be in the suits for eight to nine hours each day.
Rubins compared the Axiom suit to the ones from the Apollo missions. While it offers greater flexibility, it still weighs about 300 pounds. Even though the Moon’s lower gravity eases this burden, astronauts may struggle with basic movements. She noted that falling can lead to tricky maneuvers to stand back up, something Apollo astronauts experienced.
Not everyone shares Rubins’ worries. NASA astronaut Mike Barratt mentioned that the suit has made significant progress, recording 700 hours of pressurized testing. He thinks bending down in the suit is manageable.
To ensure safety and effectiveness, NASA plans extensive tests. These include parabolic flights that mimic the Moon’s partial gravity. The suits have also been tested underwater at NASA’s Neutral Buoyancy Lab. The agency aims to finalize the design for Artemis 3 in the coming year while making vital decisions on landing logistics.
Overall, as NASA pushes forward with plans for lunar exploration, both astronauts and engineers recognize the complexities and triumphs of returning humans to the Moon.
