International Space Station turns 15 – The Universal

exactly 15 years ago, the first crew of the International Space Station entered the premises assembled in orbit during the previous two years. The commander Bill Shepherd and cosmonauts Sergei Krikalev and Yuri Gidzenko had taken off from the Baikonur cosmodrome just two days earlier, in what represented the beginning of the “Expedition 1″ to the station.

Since then, More than 220 people from 17 countries have visited the International Space Station, forming 45 “expeditions” that have come to the place.

On the occasion of the 15 years of astronauts ISS, the NASA , one of the project managers of agencies, released facts and figures in the history of the station. For example, it is reported that the Expedition 1 performed 22 scientific research. In total, the astronauts have carried out more than 760 billion research on the ISS, which will be added to the current 191 other expeditions 45 and 46. This work has generated more than 200 thousand scientific publications.

In general, the project involves more than 100,000 people in 16 countries.

Contributions to science

The work of the Astronauts ISS has advanced different areas of science. For example, in the world of astronautics, these works bring us one step closer to an eventual arrival at Mars, through studies analyzing how the body reacts to long trips in space.

So currently the effects of isolation and overcrowding (with the mission of Scott Kelly to spend a year in space) are studied, were also analyzed the effects of these trips in vision, immune response of the body and what exercises are necessary to stay in good physical condition in zero gravity situations.

Other more operational studies have been making objects in space through 3D printing and plant food on a ship.

Beyond the exploration of the universe, developments created to monitor the health of astronauts aboard the ISS have allowed advances in medicine, such as ultrasound systems overcrowding through ever smaller and less expensive equipment, and improvements in performing eye surgery through laser (a technology used in space now used to track the movement of the patient’s eye) and the detection of breast cancer.
