A NASA profile published Aug. 3, 2026, described Ike Theriot's work as Flight Operations Surface Testing lead in the Exploration Extravehicular Activity Operations Branch at Johnson Space Center in Houston. According to the agency, he integrates flight operations testing needs across the Artemis program and was transitioning toward mission development, astronaut training and mission execution for the next lunar landing.

The report said Theriot helps develop and run simulated moonwalks at Johnson and at field sites in the United States and abroad, and helped lead development of the Lunar Grid Reference System, now incorporated into flight control systems. It said he has supported testing of NASA's government reference exploration spacesuit design and Axiom Space's AxEMU, including geologic sampling practice in the Active Response Gravity Offload System, and evaluated lighting configurations in suited test runs. He also supports International Space Station spacewalks as a certified flight controller and was recently selected as a capsule communicator, the profile said.

It further described field training alongside Artemis II crew members at Kamestastin Crater in Labrador, Canada, and Theriot's path from U.S. Army service to a mechanical engineering degree at the University of Houston and a 2016 internship at Johnson. He created a Field Navigation Exercise in Houston to build lunar surface navigation skills, the report said.
