NASA/Kevin Davis Orion’s performance and the team’s analysis on Artemis II reflect system robustness, capability to support crew, and critical insights gathered that will enhance the Artemis III mission and beyond.

NASA NASA’s Artemis II mission sent four astronauts around the Moon and brought them safely back to Earth, laying a foundation for crewed flights to the Moon’s surface. In particular, NASA measured whether the thermal protection system effectively safeguarded the crew and Orion systems as the spacecraft reentered Earth’s atmosphere.

Orion reached a maximum velocity of 39 times the speed of sound and experienced external temperatures exceeding 4, 000 degrees Fahrenheit at its peak, all while the four astronauts inside Orion stayed relatively cool with a cabin temperature in the mid-70 degree Fahrenheit range. The spacecraft reentered with precision, entering within only 192 feet of its targeted entry interface, and successfully splashed down only 0.59 miles from the predicted landing site off the coast of San Diego.

Upon the spacecraft’s return to NASA’s Kennedy Space Center in Florida after the Moon mission, thermal protection system experts began additional examination of the heat shield, made of 186 unique blocks of an ablative material called Avcoat.
