NASA’s 2025 Astronaut Candidate Class
Hiking and Geological Training
Even astronauts need to bond and learn together, much like summer camp. Recently, NASA’s 2025 astronaut candidate class participated in outdoor geology training at the Rio Grande del Norte National Monument in New Mexico, where they explored and collected rock samples.

What is it?
The photograph showing the astronaut candidates might look like a fun snapshot from summer camp, but it captures an essential training moment. This group of 10 is undergoing rigorous training aimed at preparing them for future missions, whether that be to the International Space Station, the Moon, or beyond.
Their current program includes extensive geological training, which involves classroom education, field training, scientific observations, and teamwork.
Why is it incredible?
Astronaut candidates must be prepared for numerous challenges that they may face in space. Their training encompasses various aspects, such as geological studies to understand lunar rocks, flight training in high-altitude aircraft, and survival training in diverse environments.
This foundational training is crucial as they embark on a two-year program designed to shape their capabilities for future missions—ensuring they are well-equipped to explore and conduct research beyond Earth.
