We've already talked a little bit about some of the 4K/UHD footage NASA is capturing in space with RED's 6K DRAGON camera, but this recent video is truly historic. For the first time ever, astronauts have eaten fresh food grown in space. The video is in 4K on YouTube, or you can also go here to download the 4K version:

Some more info on the video and the experiment, which they are calling Veg-01:

For the first time ever, fresh food grown in the microgravity environment of space is on the menu for NASA astronauts aboard the International Space Station. Expedition 44 crew members Scott Kelly, Kjell Lindgren and Kimiya Yui sampled the red romaine lettuce which was grown as part of the Veggie experiment after it had spent 33 days growing aboard the station. 

NASA is maturing Veggie technology aboard the space station to provide future pioneers with a sustainable food supplement – a critical part of NASA’s Journey to Mars. As NASA moves toward long-duration exploration missions farther into the solar system, Veggie will be a resource for crew food growth and consumption. It also could be used by astronauts for recreational gardening activities during deep space missions.

The higher resolution images and higher frame rate 4K videos can reveal more information when used on science investigations, giving researchers a valuable new tool aboard the space station. 

Obviously this is a major event, and if we ever plan on traveling long distances in space, growing food is going to be very important. What's great about these 4K videos is that NASA is providing them (like most of their other material) under a public domain license, which means not only can you download them, but you can also modify and use the videos in your own work, even if it's for commercial purposes. 

Here are some of the previously released videos:
