Engineering technicians Pedro Solano, left, and Aaron Poulin, right, verify alignment of an Orion heat shield test article in the Arc Jet Interaction Heating Facility, or IHF, test section. This test of Orion’s heat shield using a combination of the IHF and the Laser Enhanced Arc Jet Facility, or LEAF-Lite, capabilities will certify the heat shield for the Artemis I and Artemis II missions. This is also the first time the heat shield is tested in an environment combining the two forms of heating, radiant and convective, the spacecraft will experience on entering Earth’s atmosphere.
