Bye bye to bunny hops: when NASA astronauts next touch down on the Moon, expect them to walk almost as they do on Earth, thanks to a new generation of spacesuits offering key advantages over those of the Apollo-era.
Prototypes of the Orion Crew Survival Suit that will be worn on the journey and the Exploration Extravehicular Mobility Unit (xEMU) for the lunar surface were unveiled at NASA’s Washington headquarters Tuesday ahead of the agency’s planned return to the Moon by 2024.

Today, we previewed the next-generation #Artemis spacesuits that our astronauts will wear – 1 for launch and re-entry, and 1 for exploring the lunar South Pole. Watch a recap: https://t.co/e4cxB3rK6e pic.twitter.com/PtYSLqHq62

Standing in front of a giant US flag, spacesuit engineer Kristine Davis wore a pressurized red, blue and white xEMU suit, showing off a vastly improved range of motion thanks to bearings systems on the waist, arms, and legs.
The agency views its return to the Moon as a proving ground for an onward mission to Mars in the 2030s.
They are also extendable and therefore one-size-fits-all, meaning there won’t be a repeat of an embarrassing flub in March that caused the first all-female spacewalk to be aborted when a second medium-sized suit wasn’t available.

“If we remember the Apollo generation, we remember Neil Armstrong and Buzz Aldrin, they bunny hopped on the surface of the Moon,” NASA administrator Jim Bridenstine told a hall filled with students and interns at the space agency.
“Now we’re going to be able to walk on the surface of the Moon, which is very different from the suits of the past.”
Another key innovation is the xEMU’s unlimited capacity to absorb carbon dioxide, a byproduct of respiration that is also poisonous in high quantities.

It achieves this through a system that both absorbs and then removes the gas into the vacuum of space, unlike current systems that merely absorb it until its reaches a saturation point.
The crew survival suit, meanwhile, is designed to provide full life support for up to six days — a scenario that could be required, for example, if a meteorite punches a hole in the spacecraft’s hull.

Under the Artemis mission, NASA plans to land on the Moon’s South Pole in order to exploit its water ice, discovered in 2009, both for life support purposes and to split into hydrogen and oxygen for use as rocket propellant.
