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.

What was Planet V?

About 3.8 billion years ago, the inner planets were bombarded with a cataclysm of asteroids. Could Planet V have been the cause?

  • The Late Heavy Bombardment (LHB) occurred about 3.8 billion years ago, during which time Earth, Venus, Mercury, and Mars were assaulted by asteroids.
  • Scientists are pretty sure the LHB occurred, but they're not certain what caused it.
  • It could be that a hypothetical fifth inner planet once existed in our solar system. As it left, it may have caused the LHB.

  • Everybody from Elon Musk to Stephen Hawking has said we should colonize a 'Planet B' due to the threat to our existence. Martin Brees, the UK's Astronomer Royal, has another perspective on it.
  • "I think we have to accept that there's no planet B, which can ever be made as comfortable as the Earth," he recently told The Current's Anna Maria Tremonti.
  • In a time of ever-worsening climate change that threatens the very existence of human beings, his focus is on maintaining and fixing the planet we now live on, but still with an eye toward the stars.

  • The first human colonists on Mars are expected to endure intense amounts of stress while adapting to the planet.
  • Their maintaining mental wellbeing is critical for successful colonization efforts.
  • In a 2018 study, participants perceived a 58 percent reduction in anxiety and stress following cannabis use.

NASA releases first sounds ever captured on Mars

On Friday, NASA's InSight Mars lander captured and transmitted historic audio from the red planet.

  • The audio captured by the lander is of Martian winds blowing at an estimated 10 to 15 mph.
  • It was taken by the InSight Mars lander, which is designed to help scientists learn more about the formation of rocky planets, and possibly discover liquid water on Mars.
  • Microphones are essentially an "extra sense" that scientists can use during experiments on other planets.
