Space and astronaut, where is the Space Station?
With or without horizon
|Automatic translation||Updated May 28, 2014|
Since its first launch in 1998, up 9 astronauts permanently occupy the International Space Station. Confined in their solitude, away from sunlight, astronauts paradoxically see the immense space that surrounds the Earth, while they themselves are kept in a small space considerably. They glide at the speed of 7.7 km / s in low Earth orbit and eyes traverse the vast land areas scrolling "under" the station. They attend every day about 16 sunrises and sunsets. But it is "downward" in the night they see their only horizon, the Earth.

Astronaut Bruce McCandless became the first man to move freely with an MMU (Manned Maneuvering Unit), it is propelled by jets nitrogen. One can easily imagine the anxiety can feel a man flying at 27 700 km / h in this state of weightlessness, with as horizon our planet.
Image: The International Space Station is a 400-ton structure, stuffed with technology. With its 110 meters wide, 74 meters long and 30 meters high, the station orbit at 415 km altitude. Here, the NASA astronaut Reid Wiseman when preparing the launch of May 19, 2014 in Kazakhstan. Its only horizon is his cabin.
Where is the Space Station?
The International Space Station (ISS) is very close to the Earth and it is clearly visible at night because it reflects sunlight, thanks to its huge solar panels. When it flies over your region, you can see it and photograph it without special equipment. Because of its high speed, it is not always easy to know when and where to observe. This dynamic map shows in real time where is the Space Station, it orbits around the Earth at about 415 km altitude at the rate of ≈ 7.7 km / s.
