On the evening of Wednesday 26th April, NASA will live-stream a roundtable discussion taking place on the International Space Station. The powwow will feature legendary astronaut Peggy Whitson, and be beamed back to Earth in 4K Ultra HD resolution - no mean feat, considering most TV broadcasters haven't got to grips with 4K yet.
The live-stream is being carried out in conjunction with Amazon Web Services, the e-tail giant's cloud computing arm and can be viewed here.
4K footage has been beamed from space before, but never live. The footage will be filmed using a RED Dragon Digital Cinema Camera.
The discussion itself could also prove interesting for anyone interested in image quality, cinema and space. It's titled 'Reaching for the Stars: Connecting the Future with NASA and Hollywood', and will explore how "advanced imaging and cloud technologies are taking scientific research and filmmaking to the next level".
The fun starts at 6:30pm UK time on the 26th. We'll see you there!
