Ike Theriot: Preparing Astronauts for the Artemis Lunar Missions

• Ike Theriot serves as the Flight Operations Surface Testing lead at NASA’s Johnson Space Center, overseeing mission development and training for the Artemis program.
• A former U.S. Army veteran with a mechanical engineering background, he integrates flight operations testing to prepare astronauts for living and working on the Moon.

Lunar Mission Preparation

• Theriot develops and executes simulated moonwalks at NASA facilities and remote field locations.
• He played a key role in developing the Lunar Grid Reference System, which is now integrated into flight control systems for human lunar operations.
• He frequently serves as a test subject in the Neutral Buoyancy Laboratory (NBL) to refine procedures for both orbital spacewalks and lunar surface exploration.

Technology and Suit Testing

• He supports testing for NASA’s exploration spacesuit and the Axiom Extravehicular Mobility Unit (AxEMU).
• Using the Active Response Gravity Offload System (ARGOS), he simulates lunar gravity to evaluate geologic sampling procedures and hardware performance.
• He assesses environmental factors such as new lighting configurations to ensure safety and task efficiency in simulated lunar conditions.

Field Training and Mentorship

• Theriot conducts geological training with Artemis II crew members in remote, lunar-like environments such as the Kamestastin Crater in Canada.
• He is a certified flight controller and has begun training as a capsule communicator (capcom), acting as the primary voice link between Mission Control and astronauts.
• His leadership philosophy centers on empowering team members; he actively mentors others to conduct tests independently, building a sustainable generation of surface operations experts.
