Everybody loves some good Earth porn, and if the mission currently in progress goes off without a hitch, we'll all be in for a lot more of it. A pair of cosmonauts are currently on a spacewalk to install an Earth-facing Ultra HD camera on the ISS that will eventually livestream our blue marble to the internet in (almost) realtime.

The camera, Isis, along with a lower-res parter, are part of the UrtheCast livestreaming project, and have been sitting on the ISS, patiently waiting for installation. An initial attempt took place on December 27th, but it didn't quite work out. Once the camera is set up, it'll be calibrated for its inaugural livestream a little further down the line.

Here's to hoping the second time's a charm.
