Not to mention the changes in temperature: from minus 120 degrees to plus 100 degrees depending on exposure to the sun, with a cycle of 90 minutes from night and day because the ISS, traveling at 28,800 miles per hour, it takes so much to make a ‘full orbit 400 km above the Earth.

In short, anything but a walk that technically it has a name much less fascinating: “extra vehicular activity” even ennobled by the acronym “Eva”. Each astronaut, however, said however the wonder child of seeing it scroll underfoot Earth without even the protection of the space station during the three walks of Wilmore and Virts and the following will be prepared to allow the docking of new ships American. Remember that since the space shuttle is retired only the Russian Soyuz allows the comings and goings of the astronauts.

During connection there may be black out (actually seen the color blue out more frequently the “CRT”) because the signal can fall when the station is “covered” by the Earth. Blackout solved sometimes with long shots from the control room at NASA.
