As four astronauts travel around the moon on NASA's Artemis II mission, they will venture beyond Earth's protective magnetic field. The crew's spacecraft, Orion, will carry and protect them as they journey into deep space and serves as the main protection against the sun's intense power. During their 10-day flight, NASA and the National Oceanic and Atmospheric Administration (NOAA) will monitor the sun around the clock and translate space weather conditions into real-time decisions to protect the astronauts.
