Pilot astronauts need a minimum of a bachelor’s degree in engineering, biological/ physical science or mathematics. They must also have a minimum 1,000 hours of pilot-in-command time in a jet aircraft.
Astronauts are men and women with an outstanding ability in a scientific discipline, who are both mentally and physically fit.
Astronaut candidates tend to be selected in their 30s and 40s.

Men and women are chosen from all around the world to train for travelling in Space. They can be selected for training for three year’s. They have a year’s basic training, followed by training related to an astronauts role in space.
Astronauts preparations involve classroom and practical training, which includes work in mock-ups of orbiter spacelabs and simulators.
Astronaut candidates receive training in parachute jumping on land and sea survival. They must also train for any kind of situation or emergency.
Astronauts must train and practice tasks in space like conditions, just like space engineers, who practice in Space Station mock-ups, in preparation for future missions.

Astronauts will drink up to eleven liters of water a day.
Astronauts diet is very similar to what we eat on Earth. Items would include frozen vegetables, desserts, dairy products and fruit. An astronauts menu in the International Space Station would easily consist of a 100 items.
Astronauts sleep in sleeping bags, which they strap to the walls or ceilings to stop them floating around and bumping into objects.
Astronauts in the not to distant future can look forward to launching from American soil, once SpaceX and Boeing finish their new class of commercial vehicles. It will be the first time Americas launch from their own country since the space shuttle program was completed in 2011.
On Monday, July 20th, 2020, at 5.00 p.m, SpaceX’s Falcon 9 launched from Cape Canaveral Air Force Station in Florida with NASA astronauts Bob Behnken and Doug Hurley on board. Their missions included delivery to the International Space Station and to launch communication and Earth observation satellites. It was Americas first launch from their own country since 2011.
