The Apple TV app lets users watch high-definition live streams from NASA TV, and allows them to enjoy a real-time view of the Earth from the International Space Station.
The app also informs users of their next opportunity to view the ISS and other NASA satellites as they pass overhead, based on user location.
The app has several other features, including a slideshow viewer with more than 15,000 images, on-demand NASA videos, 2D and 3D satellite tracking maps, NASA mission news, and the ability to listen to Third Rock internet streaming radio.
"The NASA app has been a fantastic way for the public to experience the excitement of space exploration from their mobile devices," said David Weaver, NASA associate administrator for Communications in a press release.
"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."
The NASA app is available in the App Store on the fourth-gen Apple TV.
