NASA unveiled its 2025 astronaut class this week, and two familiar names popped out: Anna Menon and Yuri Kubo. Menon joined SpaceX in 2018 after a career at NASA in the Mission Control Center, where she provided biomedical support for astronauts. As a senior engineer at SpaceX, she worked on private astronaut missions and flew as a mission specialist and medical officer aboard the Polaris Dawn private astronaut mission. The training curriculum includes lessons in robotics, geology, foreign languages, space medicine, and more, alongside conducting simulated spacewalks and flight training, NASA said. For decades, NASA astronauts mostly came from the military and academia.
