NASA engineers simply completed their first apply countdown forward of a deliberate 2024 astronaut launch to the moon.
The Artemis 2 launching crew completed their first costume rehearsal on July 20, which additionally occurs to be the day that the Apollo 11 mission touched down on the moon in 1969.
This important “sim” is one in every of many who NASA will do to get a quartet of astronauts safely off the bottom no sooner than November 2024. The Artemis 2 mission’s important purpose is to ship NASA astronauts Reid Wiseman, Victor Glover and Christina Koch, together with Canadian Area Company astronaut Jeremy Hansen, safely across the moon and again.
“Every simulation is a bit science fiction story, but it surely’s a narrative that helps the launch crew, NASA and the nation to be extra profitable in our actual endeavors,” John Apfelbaum, exploration floor programs simulation coaching lead at NASA’s Kennedy Area Heart in Florida, stated in a press release. “Sure, we get to be a bit devious, and we attempt to put the launch crew in conditions they could not have considered.”

Artemis 2 will launch from Kennedy atop NASA’s Area Launch System (SLS) rocket, which has solely despatched one different mission to the moon. The liftoff of the uncrewed Artemis 1 flight on Nov. 16, 2022 went flawlessly, but it surely took a number of countdowns to get to that time. That problem illustrates how essential launch sims are to sending people to area safely.
Sims are a commonplace device at NASA for all missions, for launching, splashdown, spacewalks and different frequent astronaut actions. Such work permits for team-building, skill-building and dealing via the surprising.
Within the case of the SLS, the launch countdown takes two days — a veritable marathon that is robust to simulate repeatedly. That is why launch simulations are sometimes damaged into components.
The July 20 simulation, for instance, centered particularly on the propellant loading of liquid hydrogen and liquid oxygen, together with the terminal countdown (the final 10 minutes earlier than launch). These are key moments to guarantee the mission’s success, NASA officers stated.
“Simulations are actually key to the launch crew preparations,” Charlie Blackwell-Thompson, Artemis launch director, stated in the identical assertion.
“Typically the issues the sim crew places us via are easy. Some are difficult. A few of them end in a continuation of the launch countdown, and a few will end in a scrub determination,” she added. (Scrubs are when a launch is canceled, which occurred a number of instances with Artemis 1.)
Other forms of simulations might be carried out throughout launch coaching between now and the massive day, together with aborts, coaching alongside the astronauts and dealing with different facilities and groups in actual time.
If all goes in keeping with plan, Artemis 2 might be adopted by a crewed lunar touchdown on Artemis 3 in 2025 or 2026, relying on the readiness of the SpaceX Starship lander system. Alongside NASA, companions comparable to Canada, the European Area Company and the Japanese Aerospace Exploration Company are additionally flying astronauts and {hardware} on the Artemis missions.
The NASA-led Artemis Accords contains 27 nations to this point which can be aiming for the moon underneath worldwide peaceable exploration norms. The human missions embrace a set of actions, which additionally embody the deliberate NASA Gateway area station and plenty of robotic landers, rovers and payloads funded by NASA’s Industrial Lunar Payload Providers and different packages.
