On its way back to Earth, Orion will pass through a period of intense radiation as it travels through thethat contain space radiation trapped around Earth by the planet’s magnetosphere. Outside the protection of Earth’s magnetic field, the deep space radiation environment includes energetic particles produced by the Sun during solar flares as well as particles from cosmic rays that come from outside the galaxy.
A crew is expected to experience two-and-a-half times the force of gravity during ascent and four times the force of gravity at two different points during the planned reentry profile. Engineers will compare Artemis I flight data with previous ground-based vibration tests with the same manikin, and human subjects, to correlate performance prior to Artemis II.Orion Crew Survival System
Shortly before 2:30 p.m. CST on December 9, Orion was traveling 171,500 miles from Earth and 214,200 miles from the Moon, cruising at 2,100 mph .
