NASA HD is a free app that lets users view thousands of NASA images, information about current NASA images and videos, as well as live stream NASA TV.
The app also includes access to curated topic areas, like "Women in Space," and to NASA Twitter feeds from around the agency.
While the satellite trackers and mission information is interesting, our favorite part of the app are the photographs. NASA has a huge archive of photographs -- some of which were released to Flickr earlier this week -- and thousands of these images are accessible in the app. You can also share photos and videos via Twitter and Facebook.
Check out this gallery to see the NASA HD app in action.
