This isn't the first ultra-high definition video sent from the ISS: NASA sent the RED camera up back in January 2015 and started uploading 4K video to YouTube last June. Most of the videos in NASA's UHD archive are of experiments done inside the space station. It's cool to watch bubbles wiggle in zero-G, but it pales compared to a carefully-framed shot of the globe spinning underneath the camera.



Of course, you'll only be able to experience UHD if your display goes up to 4K, or 3840 x 2160 resolution. You'll have to manually click the quality sprocket on the YouTube screen and choose 2160p to see video in its proper format. And if you want to download any footage from the archive, go nuts — but a 4-minute clip in 4K will take up half a gigabyte.
