NASA’s Artemis II mission marked the first crewed flight around the Moon in more than five decades, with astronauts spending approximately 10 days aboard the Orion spacecraft. The mission demonstrated critical systems for deep space human exploration and built on the uncrewed Artemis I test flight.
NASA’s Ames Research Center played a crucial role by developing sensors to collect heat shield performance data during reentry, including measurements of temperature and pressure. This data was vital to ensure crew safety as Orion reentered Earth’s atmosphere at speeds near 25,000 mph and temperatures up to 5,000 degrees Fahrenheit.
Ames engineers also contributed to the design of Orion’s 3D-MAT compression pads, which connect the crew module to the service module. These pads provide mechanical strength and thermal insulation under extreme heat, representing advances with potential applications beyond human spaceflight.
The Aerosciences team at Ames supported detailed aerothermal simulations to help predict the spacecraft’s trajectory and environmental conditions during reentry. They combined onboard sensor data with computational models to inform mission planning and analysis.
Lessons learned from Artemis II, including heat shield performance and spacecraft trajectories, are expected to guide future Artemis missions targeting lunar surface landings and sustainable exploration.
