NASA Explorers: Training the Astronauts

Astronauts train all over the world, including at NASA’s Johnson Space Center in Houston, Texas. Here, they learn not just how to live in space, but also how to conduct science in microgravity. Astronauts serve as the eyes and hands of researchers while their experiments are aboard the space station, so they must be trained in everything from using a microscope, to maintaining the equipment for combustion experiments.
