NASA iPhone Time Travel App

This is an exploration into time travel via an iOS and Android app, requested by Google as part of a three-hour design challenge. The challenge was thus:

"Demonstrate how you can apply a common visual language for a NASA time travel app, which consists of a UI that identifies where in time you are, where in time you want to go, and an actionable affordance to initiate time travel (don’t worry about flows). Provide a screen for both an iOS phone and an Android tablet that are on brand, while also being considerate of native platform design guidelines."
