“Now, users with the latest Apple TV can explore and enjoy our remarkable images, videos, mission information, NASA Television and more on the big screen with the whole family,” said NASA associate administrator for communications David Weaver in a press release. Sounds wholesome!
Mainly, though, this opens up the possibility of having your TV be a constantly on, live view from the ISS, which is probably the greatest thing any TV could possibly do.
Grab the app from the Apple TV app store — or head here for links to other versions.
