Design your own rocket ships. Blast off into space. Explore the solar system. See if you have what it takes to be a rocket scientist.
Choose and connect parts together to build rocket ships. You can choose from a variety of rocket engines, fuel tanks, and other gizmos. You can even build rovers with powered wheels. You are only limited by your imagination.
Blast off from any planet you want. You can fly through the intense atmosphere of Venus, or you can take advantage of the low gravity of Mercury. Whip around the sun and launch yourself out to the far reaches of the solar system.
Several challenges are built into the game so you can compete with other humans from around the world to see who can go the fastest, fly the farthest, orbit with the least amount of fuel, land on the moon, and so much more
