From left, Beverly Case, handling, mechanics & structures engineer for contractor Jacobs, and David Valletta, NASA ignition overpressure protection and sound suppression engineer, participate in the 11th terminal countdown simulation for the Artemis I launch inside Kennedy Space Center’s Launch Control Center on Oct. 14, 2021. The event marked the first time members of NASA’s mission management team, launch team, and Jacobs conducted the simulation together. During Artemis I, the agency’s Orion spacecraft will lift off from Kennedy aboard NASA’s most powerful rocket – the Space Launch System – to fly farther than any spacecraft built for humans has ever flown. Through NASA’s Artemis missions, the agency, along with commercial and international partners, will establish a sustainable human presence on the Moon to prepare for missions to Mars.
