  • Freerunning and parkour taught Palmer the power of pushing past fear to reach and exceed one's goals. By learning to understand personal triggers for fear, humans can effectively rewire their brains.

Always dreamed of flying? On these moons, you can.

There are places in our solar system where you can fly.

  • Both the moon and Mars have a weaker surface gravity than the Earth does. The result? You don't weigh as much on either celestial body as you do here.
  • On a moon called Titan that orbits Saturn, the gravity isn't as strong as Earth's, but the atmosphere is much thicker. In this world, it would be possible to strap wings to your arms and fly around.
  • On a low-gravity moon called Miranda, just off the space coast of Uranus, there are cliffs that are many miles high. It would be possible to jump off a cliff here and fall very gently to the bottom.
