Artemis III Launch Simulations (Terminal Count Sim)
Alex Pandelos, engineer with NASA’s Exploration Ground Systems Program, participates in a terminal countdown simulation for Artemis III on Thursday, Aug. 6, 2026, inside Firing Room 1 of the Rocco A. Petrone Launch Control Center at NASA’s Kennedy Space Center in Florida. The terminal count simulation conducted by NASA’s Exploration Ground Systems team runs through the final five hours of launch countdown, including terminal count - the remaining 10 minutes of the countdown. Artemis III will carry out a series of objectives in low Earth orbit designed to demonstrate critical systems needed for future lunar landings, beginning with Artemis IV.
