HD cameras show Earth from space

A view of Earth from the International Space Station.

High-definition cameras are showing us what Earth looks like from space as never before.

NASA is providing a live, HD video stream of our planet as seen by astronauts on the International Space Station.

The ISS is equipped with four high-definition earth-facing cameras. They are 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.

The livestream is available online.
