New spacesuits for the first woman and next man on the moon

(CNN) – A human hasn’t landed on the moon since 1972, but NASA’s Artemis program aims to land the first woman and the next man on the lunar surface by 2024. Part of that process involves upgrading the classic spacesuits worn by Apollo-era astronauts in the 1960s and 70s.

NASA revealed two new spacesuits for the Artemis astronauts on Tuesday with live demonstrations. The suit for the planned landing at the lunar south pole is called the Exploration Extravehicular Mobility Unit, or xEMU, because the red, white and blue suit itself is a bit like a spaceship in the way it protects the astronauts, NASA said. A second orange suit called the Orion Crew Survival System will be worn during launch and re-entry in the Orion spacecraft and provide thermal protection for the astronauts.
The suits improve on the technology used in the Apollo suits as well as those currently used by astronauts on the International Space Station. These will also accommodate more sizes and provide more comfort and mobility. Bearings replace zippers for more mobility in the pressurized suits.
When NASA created the first space missions, they knew astronauts flying on the Mercury and Apollo missions would need special suits. Most of the men were Air Force test pilots. And fittingly, the suits were upgrades of Navy flight suits for high altitudes.
The agency now knows more about the moon and what to expect on the lunar surface. For example, ahead of the Apollo 11 moon landing, engineers worried that the moon dust wouldn’t be stable enough to support the lunar lander or even astronauts walking on it.
They discovered a different risk in the dust — tiny shards of glass-like material. And the moon’s temperature extremes could compromise the safety of the astronauts.
The new suit is designed to keep out dust so that it doesn’t infiltrate the life support system and can keep an astronaut safe between the temperature extremes of negative 250 degrees to 250 degrees Fahrenheit, accounting for shade and sun, especially at the south pole.
