Surprising Science
  • 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.

How the Moon’s ice craters will power a human colony

Astronauts will be able to harvest the Moon's natural resources to sustain human life.

Videos
  • NASA's Michelle Thaller walks us through what it will take to sustain human life on the surface of the Moon.
  • One way would be to run a very strong electrical current through water, separating it into hydrogen and oxygen. It's how astronauts on the International Space Station currently harvest oxygen to breathe.
  • There's already evidence of ice at the Moon's poles, likely thanks to billions of years of asteroid and comet collisions. All we have to do is harvest it. People on the future Moon base could also use those ice repositories to make liquid rocket fuel.
