For four-generations, Diamond St. John’s family has been supporting human spaceflight at NASA’s Kennedy Space Center in Florida. Now, she’s continuing the family legacy that reaches back to Apollo —helping return humanity to the Moon with the agency’s Artemis campaign.
St. John is an engineer with Lockheed Martin supporting Orion, NASA’s spacecraft built to carry crew to the Moon and return them safely to Earth on Artemis missions. She specializes in the production of Orion’s heat shield at Lockheed’s Spacecraft, Test, Assembly and Resource Center, in Titusville, Florida. As one of the most important elements of the spacecraft, the heat shield is responsible for protecting the astronauts from the nearly 5,000 degrees Fahrenheit temperatures as they re-enter Earth’s atmosphere at the end of the mission.
From start to finish, St. John is responsible for establishing a production workflow for the Orion heat shield — the largest of its kind in the world — and ensures each step is executed in the correct order along the way.
Her team recognizes the criticality of their work and knows that their mission is to make sure astronauts come home safe. When it comes to quality of production, St. John embraces that mindset.
“We always want to make sure that we’re doing things right. We have to slow down and make sure that our product is quality — because the slightest thing can be a make or break. We definitely want to make sure that our crew is safe.”

St. John and her team are working on the Orion heat shield for the Artemis III mission that will land astronauts on the lunar surface. The team is in the process of bonding 186 tiles made of a material called Avcoat to the heat shield’s underlying structure. “Once we start bonding operations, we first sand the blocks, to make sure that we minimize any gaps between them. Then we get into bonding, and we fill the gaps, and we test. After that’s complete, we then paint and tape the heat shield.”
“Seeing a final product finished, it warms your heart. So, I’m looking forward to that finished heat shield and knowing that we put our heart and soul into it.”

Though she is currently working on the heat shield for Artemis III, her journey with Orion began with the Artemis I spacecraft. St. John started on the clean room floor as a technician intern with subcontractor ASRC Federal. She then moved into a full-time role with the company for four years in quality inspection while earning her bachelor’s degree in engineering. After that, St. John joined Lockheed Martin as a manufacturing engineer.
“Everything has been Artemis from the beginning,” she said, in reflection of her career. “Knowing that my great grandparents worked on the Apollo missions — it’s cool to follow down that same path. I think they would be pretty proud.”
