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.

Astronaut Kjell Lindgren exercises using the ARED The Advanced Resistive Exercise Device ( ARED ) is an exercise device designed by NASA to allow for more intense workouts in zero gravity . The device was flown to the International Space Station during STS-126 [ 1 ] and installed in 2009 to replace its inefficient predecessor, the Interim ...
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 ...
Astronauts take hundreds of stunning photos from the International Space Station.. This year's best snapshots reveal both Earth and space in glorious detail. Check out astronauts' views of ...
The Gateway to Astronaut Photography of Earth has been collecting and categorizing photos taken by astronauts. They see Earth from an altitude of about 250 miles as the station travels at a speed ...
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.
Astronauts aboard the ISS, on the other hand, are much farther from Earth's center of gravity than the rest of us — about 260 miles farther. So, in that case, astronauts actually age slower .
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 ...
