NASA unveils new spacesuits for missions to the Moon and to Mars

The new spacesuits offer increased freedom of movement and protection from extreme temperatures and radiation.

NASA presented two new types of spacesuits intended for missions to Mars and to the Moon. One of them — OCSS (Orion Crew Survival System) — will be used for space flights. The second model, called xEMU (Exploration Extravehicular Mobility Unit), is intended for carrying out tasks on Mars and on the Moon. 

One of the defining features of the new spacesuits is the increased freedom of movement they offer. Additionally, these suits are unisex and suitable for both men and women.

OCSS is a lightweight spacesuit that protects its wearer from high temperatures and radiation. It was developed with the main goal of protecting crew members in case of spaceship depressurization. Notably, the spacesuit itself is not constructed hermetically, and it features a special rapid fastening, which has not been revealed in details yet. Special thermal tubes inside the suit are used for temperature control. The full set features a pair of gloves made from a sturdy material that is compatible with touch screens.

The xEMU spacesuit can be worn in temperatures ranging from -121 up to 121 °C. This version is individually created for each astronaut and intended for carrying out tasks on the surface of the Moon or Mars. 

NASA plans to start equipping expeditions with new spacesuits by 2024. The first astronauts to test them will probably be the ones participating in the Artemis Mission.
