NASA’s latest cohort of astronaut candidates, the Class of 2025, is undergoing an intensive, multi-faceted training regimen as they approach the halfway point of their nearly two-year program. This rigorous preparation is designed to equip them for a range of future space endeavors, from missions in low Earth orbit to ambitious journeys to the Moon and eventually Mars.

The candidates are actively engaged in geology training, a critical component given the potential for future Artemis missions to the lunar surface. Following classroom instruction at Johnson Space Center, they participated in field training at New Mexico’s Rio Grande del Norte National Monument. Further enhancing their geological expertise, several candidates joined experienced NASA astronauts and Artemis mission support teams for field training in Iceland, where they honed skills in geologic observation, sample collection, navigation, and collaborative teamwork – all directly applicable to lunar exploration.

Beyond geological studies, the candidates are building essential flight proficiency. This summer’s training included flights on NASA’s high-altitude WB-57 aircraft and the commencement of training in T-38 supersonic jets. These flight experiences are crucial for developing confidence, coordination, adaptability, and resilience in demanding environments. Complementing flight training, candidates are also undergoing altitude chamber runs to simulate the pressure conditions encountered during high-altitude flights and in space, ensuring familiarity with operational protocols and safety procedures.

Furthermore, the astronaut candidates are engaged in comprehensive survival training, including water survival exercises conducted in the Neutral Buoyancy Laboratory. These simulations prepare them for potential emergency landings in remote locations and simultaneously foster teamwork and decision-making skills. The training also encompasses intensive Russian language studies, cross-cultural preparation, spacecraft systems operation, spacewalk simulations, and emergency procedure training, ensuring they are well-rounded for international and complex space missions. The Class of 2025 is on track to graduate in 2027, poised to join the active astronaut corps and await their assignments to advance NASA’s deep space exploration objectives.
