Live ISS HD Stream Update: Earth Is Looking Particularly Beautiful Right Now


Earlier this week we reported on how NASA has finally attached four HD webcams to the side of the International Space Station.

The video footage at the time was decent, but today it's... well, it really is out of this world.

The ISS is currently broadcasting some amazing full HD pictures of the rolling Earth, and it looks just stunning.

Put it full screen, play some favourite music and just sit back and watch it.

The cameras are sensitive instruments, and are housed in temperature controlled cases with dry nitrogen inside.

The images are sent back to Earth and reformatted, before being sent out live on the internet at pre-arranged times. The footage is not constant, and is at times totally dark depending on the position of ISS relative to the Sun. Watch long enough and you can see a sunrise or sunset every 45 minutes.

While the crew is on duty the cameras will provide a view of the inside of ISS. When the crew is off duty, it will turn again to the Earth.

But watch the video at the right time and the result is startling - a live, rolling view of our planet that only astronauts usually get the chance to see.

Nasa said the aim of the experiment is to test how the cameras work in space, and what effect radiation has on the equipment.
