Earth from space in high definition

Posted:

Ever wonder what earth looks like from space in high definition?

Wonder no more. NASA is now providing a live HD video stream of the blue planet as seen by astronauts on the international space station.

The ISS is equipped with four high def earth facing cameras. It's all part of an experiment to assess camera quality for use in space. NASA hopes to find out how the cameras are able to survive and function in the extreme radioactive environment of low-earth orbit.
