Summer Training: Catching Up With NASA’s Astronaut Candidates

Did you spend part of your summer camping, hiking, at the pool, or in an aircraft? So did NASA’s 2025 Astronaut Candidate Class.

The 10 candidates have been working their way through a comprehensive and rigorous training program since the agency introduced them to the public on Sept. 22, 2025, from NASA’s Johnson Space Center in Houston. They are approximately halfway through the nearly two-year training program, which will equip them for missions to low Earth orbit, the Moon, and ultimately, Mars.

Geology Studies

Since the astronaut candidates can one day be assigned to a future Artemis mission to the lunar surface, geology courses are an important part of their training. In May, candidates completed classroom trainings at Johnson before venturing to the Rio Grande del Norte National Monument in New Mexico for additional classroom instruction and training in the field. Several candidates also joined NASA astronauts and Artemis mission support teams for geology field training in Iceland in July. They practiced geologic observations, sampling with tools, navigation, and teamwork, all skills and processes that translate directly to Artemis lunar missions.

Flight Training

Whether learning to become a pilot or sharpening their existing piloting skills, astronaut candidates train in aircraft to build confidence, coordination, adaptability, and resilience in high-stakes environments. This summer, that training included flights on NASA’s WB-57s – a trio of long-range, high-altitude airplanes that have flown research missions since the 1960s. The class also began flying NASA’s T-38 supersonic jets.

Altitude Chamber Runs

Candidates have also spent time in one of Johnson’s altitude chambers as part of their flight training. These unique facilities allow NASA to simulate physical pressure levels ranging from those at sea level to near vacuum. After donning flight suits and helmets, candidates enter the chamber to familiarize themselves with the conditions they will face on high-altitude flights and in space, and to practice different protocols and interventions designed to keep them safe.

Water Survival Training

Candidates continued survival training to prepare for the unlikely event of landing in remote environments after a mission. Water survival exercises in Johnson’s Neutral Buoyancy Laboratory, or NBL, simulate these scenarios while also building teamwork and decision-making skills.

On top of these exercises, candidates are completing intensive Russian language classes and cross-cultural training to prepare for missions spanning countries and continents. They are learning to operate spacecraft systems used in human spaceflight missions, conducting spacewalk training at the NBL, and training inside other mockups of space vehicles. They are also learning emergency procedures, maintenance, and repair of spacecraft.

The class is on track to graduate in 2027, when they will join NASA’s active astronaut corps and await their first flight assignments. Whether they go on to contribute to research taking place aboard the International Space Station or venture to the Moon to prepare for future Mars missions, the graduates will have the operational expertise, scientific knowledge, and technical background necessary to advance NASA’s deep space exploration goals and sustain a long-term human presence beyond low Earth orbit.
