             Download it from the AppStore             Get it on Google Play

  • What can I do with the Gravity Launch app?
    • Play games on your own or against a friend.
  • Do I need to be online to use the app?
    • No. Once the app has been downloaded it will be fully functional, even when the device is not connected to the Internet.
  • How much does the app cost to download? Are there in-game costs?
    • Gravity Launch costs nothing to download, and there are no in-game costs. Science NetLinks and AAAS are offering this app for free as a service to the community.
  • How do I play?
    • Use the two dials marked Thrust and Launch Point to adjust where you want your spaceship to go. Tap the Launch button and see if you were right. Need more instruction? There's a button at the bottom of the app screen marked "How to Play." Tap on that and it will walk you through the steps. Watch this training video to get a better idea of what the games will be like.
  • Can I play against a friend on another device?
    • No, sorry. You can only play against someone who's within reach of your device.
  • Does the app have any other special features?
    • Yes, you can set up multiple accounts within the settings of the game in order to allow various people to solve the games independently while sharing the same tablet. (You also can change the colors of your rocket trail.)
  • Do you have resources for using this app in my classroom?
    • Yes! We have our Gravity Launch App tool that provides some suggestions for using the app in your classroom. We also have a Gravity Launch Mobile lesson. Teachers without tablets can refer to the Gravity Launch lesson and tool that use the older Flash version of the game.
  • The dials are really hard to control.
    • They can be a bit finicky. But make sure you're using the bottom dial if you're just trying to make a small change. That gives you finer control than the top dial.
  • I created a new player name, but it's not showing up in the list. What gives?
    • Does your username start with a lowercase letter? Those all appear after the list of names that start with a capital letter.
  • My friend and I were playing a two-person game and I won. Why won't it let me get back to the main menu?
    • Only the person still trying to solve the game can hit the menu button while their game is still active. It didn't seem fair that you should be the only person to get to solve it.
  • Why doesn't the game have any sound?
    • It does. Make sure the hardware mute toggle switch on your device is not set to mute and that the volume is turned up.
  • I wanted to take a snapshot of my game, but nothing happened. What went wrong?
    • If you're on an iPad, check your photos app. If you're on an Android-based device, it should be in your gallery. You should find them tucked in there. If not, let us know by using our contact form, and we'll see if we can figure it out.
  • What is your privacy policy?
  • Is your app compliant with FERPA and COPPA?
    • Yes. The Gravity Launch app does not collect any information from users after the app is downloaded, making it compliant with both FERPA and COPPA.
  • Is your app enabled for VPP Device assignment?
    • Yes, as of early 2016.
  • Who designed the app for you?
  • Will you be making the game available in other formats?
    • Probably not. The game is now available for Android-based tablets and for the iPad. (While it is possible to download and play the game on Android-based phones, the app is not optimized for that experience and we don't recommend it.) We also have an older, Flash-based version you can play over the Internet on your home computer. It was designed as part of Kinetic City.
  • Some of these levels are really hard. Are you sure there's an answer?
    • Yes, and usually more than one.
  • Are you using the actual scientific calculations for the amount of thrust that would be necessary to pilot a rocket on these missions?
    • No. While the concepts are accurate, we're using bogus numbers. Please do not attempt to pilot a real spacecraft using your Gravity Launch solutions.
  • I have successfully completed all the missions. Do you think NASA will lend me a spacecraft?
    • No. They wouldn't even lend one to us when we promised to be really careful! They're really expensive! But if you'd like to pursue becoming an astronaut in real life, NASA's website is a good place to start. Generally, you'll want a college degree in science, math, or engineering; to be in good physical health; and to be a U.S. citizen. (Other national and international space agencies have their own sets of guidelines, so if you don't plan to become a U.S. citizen, check out their standards.)
  • Do you have any other apps I can play?
    • Yes! Check out Classify It!, which will let you sort organisms into different categories. In the meantime, you could play some more of our games on a computer that allows Flash. Check out our collection of Science NetLinks interactives.
  • I think it's really great you've made this app available for free. Who are you? Are you a superhero?
    • Yes. Yes, we are.
  • I've got another question. Help?
