Listen to this audio excerpt from Grace Lauderdale, exploration project manager for the Training Systems Office at NASA Johnson:
In preparation for their mission around the Moon inside NASA’s Orion spacecraft, the Artemis II crew will spend countless hours training inside the Orion Mission Simulator. The simulator replicates what the crew will experience inside the spacecraft and allows the astronauts and flight controllers to rehearse every phase of the mission.
As the exploration project manager for the Training Systems Office at Johnson, Grace Lauderdale leads the team that develops and operates the Orion Mission Simulator at NASA’s Johnson Space Center in Houston, playing a key role in making sure astronauts and flight control teams are ready for the first crewed mission of the Artemis campaign.

The simulator is more than a mock-up. It connects directly to Johnson’s Mission Control Center, sending real-time data, audio, and video — just like the spacecraft will during flight. That means the flight control team trains in parallel, seeing and hearing exactly what they would throughout the mission.
“One of our major goals is to make the data they see on their displays look like the real vehicle,” Lauderdale said. “We also simulate the near space and deep space networks, including all the communication delays. It’s all about realism.”
That realism is powered by a complex software system developed in collaboration with partners like Lockheed Martin. Lauderdale’s team works behind the scenes to ensure the simulator runs smoothly — writing code, troubleshooting issues, and even creating custom malfunctions to challenge the crew during training.
To prepare astronauts for the unexpected, instructors work with Lauderdale’s team to simulate problems that could occur during the mission, some of which require creative solutions.
“There are times when the instructors will ask for malfunctions or capabilities that the sim doesn’t automatically do,” she said. “Part of our role is to come up with ways to make that happen.”
Her team plans, develops, and executes training scenarios in the Orion Mission Simulator across multiple Artemis missions, often simultaneously. “Currently, we’re planning for future crewed missions, developing Artemis III, and executing Artemis II,” she said.
The work is demanding, but deeply personal, according to Lauderdale.

That passion shows in her leadership. Her team often works nights, weekends, and holidays to ensure the simulator is ready. During a recent 30-hour simulation, they spent days preparing, fixing memory issues, and ensuring the system wouldn’t crash. It didn’t.
“I’m very proud of my team,” she said. “They’ve put in countless hours of work to make sure this simulator reacts exactly as it would in the real mission.”
For Lauderdale, helping send astronauts around the Moon isn’t just a job—it’s a dream realized.
“Being part of getting us back to the Moon is very personal to me,” she said. “And I’m proud to be part of the team that will help get our astronauts there.”
