When astronauts in Orion venture far beyond Earth into deep space, they will expand humanity’s frontier and push the boundaries of exploration. While the spacecraft is designed with systems and materials to keep the crew safe during their journey, leaving the protection of Earth’s magnetosphere exposes astronauts to a radiation environment in space that scientists and engineers at Johnson Space Center in Houston are working hard to protect against. NASA works to protect astronauts from radiation and limit their exposure over time because chronic effects can, for example, include an increased risk of cancer. To limit risks in Orion, the team is developing a way to make use of the mass on board the spacecraft to protect the crew and recently conducted evaluations at Johnson to test procedures for getting astronauts into their protective environment as quickly as possible. Engineers conducted testing in a representative Orion to evaluate procedures that will be used to protect astronaut...
