A key part of an astronaut\u2019s job is to study how things work without gravity. For over 20 years, astronauts on the International Space Station (ISS) have made amazing discoveries to help us understand\u00a0science and life on both Earth and Space.<\/p>\n<\/div>\n

\u201cWe are up here in space because we want to do a lot of experiments, zero g experiments, there is a lot of stuff in physics, chemistry, medicine, that we can learn from being here in weightlessness and doing this research.\u201d said ESA astronaut and scientist, Matthias Maurer\u00a0\u201ceveryone around the world can propose science objectives for this Station\u2026\u00a0if we work together, we can achieve so much.\u201d.<\/p>\n

One of the most interesting problems being studied is how our bodies get used (adapt) to the unique world of weightlessness. Not only does this help our understanding of human biology, but it is also the key to future exploration of the Moon or Mars.<\/p>\n

Scientists want to know about every part of the crew\u2019s health. People keep track of what food they eat and how their diet affects them. That means taking samples\u00a0of blood, urine and pieces of hair, storing them in a freezer and sending them back to Earth to be studied. Two special watches worn by the astronauts track their movement. Different body scans are also part of their daily timetable.<\/p>\n

These studies can directly help people on Earth, as well as astronauts on long space missions. They bring hope to people who suffer from weakened bones, heart and lung diseases, and age-related problems.<\/p>\n

One of these projects, the Orbital Architecture Study, is investigating how the design of the Space Station can affect how astronauts think and feel. This can help us find out how to help people feel calmer and more focused\u00a0in places in space and on Earth.<\/p>\n
