With the help of four cameras, NASA enables every internet user to see the Earth as if he were at the International Space StationISS). The HD video it "rises" directly in the channel of the US space agency in Ustream, while you can also visit and the website created for this purpose by NASA.
The four cameras are commercial models and have been installed on the exterior of Columbus, the European segment of the International Space Station, as part of the High Experiment Definition Earth Viewing (HDEV). The goal of the experiment is to test them in real conditions by October 2015, so that the technicians of the service can check which ones are durable enough to be included in future space missions.
The video captures the spectacular view of the planet from space, while the ISS is on the Earth's side that is currently illuminated by the sun. The image is not accompanied by sound, so to add the soundtrack of its choice, as NSAA writes.
Because the image "blacks out" when o spaceman σταθμός περνά από τη σκοτεινή πλευρά του πλανήτη, η ΝΑΣΑ έχει προσθέσει στην ιστοσελίδα of an interactive map that shows the position of the ISS at any time, showing whether it is over the bright or dark hemisphere.
When the video is covered in gray, it means either NASA changes transmission to a different camera, or ISS is temporarily lost. In this case, those who can not wait can see some of the video clips in the space service channel.
Although the experiment officially started from May 2, due to a technical problem in the first few days the relay was interrupted for long periods of time. For about 24 hours now, however, it seems that the fault has been fixed, since the channel is generally working normally. In fact, until now its views have exceeded 7,9 millions.
