From LunaCognita: In recent months, NASA has released into their photographic archives a series of exceptional still-frame sequences that were shot in Earth orbit aboard the International Space Station by the crew of ISS Expedition 30. These sequential photographic stills were exposed during numerous "night side" orbital passes using a mounted Nikon D3S digital-SLR camera aimed out different windows aboard the space station, with the camera being set to expose at various stop-motion frame rates (the fastest being a 1fps exposure rate).
I am sure many of you have already seen these video sequences on the web, as the space agency has already published many of these still-frame sequences in individual video format in their "Gateway to Astronaut Photography of Earth" online archives, but although those videos offered in that NASA archive are labeled as being "HD" quality, they are not published there in true HD format. The NASA Gateway "HD" video archive versions of these sequences are only rendered at 840x559, presumably to keep the files to a respectable size. Thankfully though, the NASA Gateway archives also contain all the original high-resolution (4256x2832) sequential photographs that the space agency used to create their "HD" video renderings, so I have simply downloaded some of those many high-resolution sequential still frames, animated them together and rendered them at 1080p in my first attempt to create a true high-definition video showing a series of these remarkable scenes. I think these sequences really are some of the most beautiful in the NASA archives, giving us a truly spectacular nighttime look at our planet Earth as it passes below the ISS, as well as views of stunning auroral displays and our Milky Way beyond.
This video is my first attempt at rendering at 1080p that I have released on Youtube, and I thought these wonderful visual sequences would be an excellent test to see how my new computer handles rendering at this resolution. I hope you enjoy the visuals shown here as much as I do, because these really are exceptional scenes giving us a unique view of our beautiful planet as viewed from low-Earth orbit!
Here is a link to NASA's "Gateway to Astronaut Photography of Earth archives - Crew Earth Observation Videos" page, where you can download both the individual NASA versions of these videos and the original high-resolution raw image files used to construct the sequences in case you wanted to make your own HD videos of these scenes.
