The selection and training of astronauts are integrated processes to ensure the crew members are qualified for space missions. [6] The training is categorized into five objectives to train the astronauts on the general and specific aspects: basic training, advanced training, mission-specific training, onboard training, and proficiency maintenance training.

An astronaut training at the Neutral Buoyancy Laboratory at the Johnson Space Center. Neutral buoyancy simulation with astronauts immersed in a neutral buoyancy pool, in pressure suits, can help to prepare astronauts for the difficult task of working while outside a spacecraft in an apparently weightless environment.
The term "Astronaut Candidate" (informally "ASCAN" [12]) refers to individuals who have been selected by NASA as candidates for the NASA Astronaut Corps and are currently undergoing a candidacy training program at the Johnson Space Center. The most recent class of astronaut candidates was selected in 2021. [13]
Space Florida in discussions with a company that wants to build a $250 million private astronaut training facility near the Kennedy Space Center.
In the late 1980s NASA began to consider replacing its previous neutral-buoyancy training facility, the Weightless Environment Training Facility (WETF). The WETF, located at Johnson Space Center, had been successfully used to train astronauts for numerous missions, but its pool was too small to hold useful mock-ups of space station components of the sorts intended for the mooted Space Station ...
Astronaut Candidate is the rank of those training to be NASA astronauts. Upon graduation from training, candidates are promoted to Astronaut and receive their Astronaut Pin. The pin is issued in two grades, silver and gold, with the silver pin awarded to candidates who have successfully completed astronaut training and the gold pin to ...
NASA hires a new astronaut class every four years or so, and back in 2015, a peak year, there were about 12,000 applicants—a number that could be matched this time around too, says April Jordan ...
During training exercises, neutral-buoyancy diving is used to simulate the weightlessness of space travel. To achieve this effect, suited astronauts or pieces of equipment are lowered into the pool using an overhead crane and then weighted in the water by support divers so that they experience minimal buoyant force and minimal rotational moment ...
