The NASA app, available right now on Apple's App Store, will improve the way people explore and experience NASA content on their smartphone or iPod, the agency said.
The updated app offers information and links to all NASA visitor centers and a section about NASA programs, Slashgear.com reported. It provides integrated weather forecasts in the spacecraft sighting opportunity section for users who like to try to spot NASA spacecraft orbiting Earth.
An estimated 4.7 million people have downloaded the app, NASA said.
The new version 2.0 requires 1OS 5.0 or higher to operate, the space agency said.
