The first manned flight with SpaceX's Crew Dragon capsule, which will take astronauts between Earth and the International Space Station, is set to launch next year.
While the real astronauts prepare for the launch, NASA has released an app that gives the public a better understanding of the prep and launch.
The app is called "Rocket Science: Ride to Station," that will let you experience a takeoff aboard the Crew Dragon or even Boeing's CST-100 Starliner.
The app is available for download on iOS and on desktop.
