The International Space Station is one of the most ambitious space projects that man has done, its construction began in 1998 and has an estimated cost of the ESA of 100 billion euros over the 30 years which is probably in operation. Some consider it the most expensive object ever built.
But it was until less than a month since the International Space Station had internet access. Why? if we forget the costs, is technically difficult to achieve decent connections to an object that is 460 miles high and moving at about 27,700 mph. There is also the safety factor: not in the interests of NASA or U.S. government somehow being intercepted communications from the astronauts in space or implanting computer viruses that are at the station.
So how did it? the solution is rather curious. First the security issue: the connection to the sites is not direct, is through a remote session to control the desktop of a computer that is on Earth, using VNC type software. Thus any attack, virus, spyware or malware affects the team on the ground and not notebooks in the international space station.
To achieve a stable data connection using Ku-band satellites under (Kurz-unten band) which are responsible for relaying information from the space station to the base of operations on Earth. In fact it’s the same technology used by providers of satellite internet access. Inside the station there is Wi-Fi routers (Netgear brand, for the curious) that were installed in 2008 and is already used for internal email and videoconferencing between Earth and space.
