Crew Survival Patch - Orion Crew Survival System (OCSS) 

Orion Crew Survival System (OCSS) Suit patch worn on the orange spacesuit

Approximately 4" diameter

Before astronauts launch on Artemis missions to the Moon, they will suit up in a bright orange spacesuit called the Orion Crew Survival System (OCSS). This spacesuit, worn inside NASA’s Orion spacecraft, is designed for a custom fit and equipped with technology features to help protect astronauts on launch day, in emergency situations, throughout high-risk parts of missions near the Moon, and during the high-speed return to Earth.

Many missions, including Artemis, require two spacesuits – one like the OCSS, worn inside a spacecraft during dynamic activities such as launch and reentry through Earth’s atmosphere; and another worn outside a spacecraft during spacewalks that functions as a self-contained personal spaceship. While a services approach is a new method for developing spacesuits, NASA is embracing commercial partnerships to design and develop suits for spacewalks. NASA is already successfully using this public-private partnership strategy today, for launch services and both crew and cargo deliveries to the International Space Station. NASA is also leveraging industry partnerships for other key Artemis elements, including human landing system services and Gateway deep space logistics services.

 The Orion suit, sometimes called a flight suit or a launch and entry suit, has been enhanced from head to toe with improvements to the suit worn on shuttle missions. Starting at the top, a number of features on the helmet allow for improved comfort and function. The helmet is lighter, stronger, comes in more than one size, helps reduce noise, and is easier to connect to the communications system needed to talk to other crew members and mission control.

The outer cover layer, which is orange to make crew members easily visible in the ocean should they ever need to exit Orion without the assistance of recovery personnel, includes shoulder enhancements for better reach and is fire resistant. The suit is a pressure garment that includes a restraint layer to control the shape and ease astronauts’ movements. A reengineered zipper also allows astronauts to quickly put the suit on and has increased strength. New adaptable interfaces supply air and remove exhaled carbon-dioxide. The suit has improved thermal management that will help keep astronauts cool and dry. A liquid cooling garment worn underneath the suit, a bit like thermal underwear with embedded cooling tubes, was revamped to be more breathable and easier to build.

While shuttle-era spacesuits came in off-the-shelf sizes like small, medium, and large, the Orion suits will be custom fit for each crew member and accommodate astronauts of all sizes. The patterns of the suit now minimize the spots of discomfort common during the shuttle era when worn pressurized for long periods of time. The gloves, the part of a spacesuit that receives the most wear and tear, are more durable and touch-screen compatible, and improvements to the boots provide protection in the case of fire, fit better, and help an astronaut move more nimbly.

Even though it’s primarily designed for launch and reentry, the Orion suit can keep astronauts alive if Orion were to lose cabin pressure during the journey out to the Moon, while adjusting orbits in Gateway, or on the way back home. Astronauts could survive inside the suit for up to six days as they make their way back to Earth. The suits are also equipped with a suite of survival gear in the event they have to exit Orion after splashdown before recovery personnel arrive. Each suit will carry its own life preserver that contains a personal locator beacon, a rescue knife, and a signaling kit with a mirror, strobe light, flashlight, whistle, and light sticks.

Through extensive design and engineering enhancements, the Orion suit will help provide an additional layer of protection for astronauts who embark on Artemis missions. These missions will include landing the first woman and first person of color on the lunar surface, sending a suite of new science instruments and technology demonstrations to study the Moon, and establishing a long-term presence there. Using Artemis experiences and technologies, NASA will prepare for humanity’s next giant leap—sending astronauts to Mars.
