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.

  • 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.

  • Today, that price has gone down to just $11.
  • Even if it's cheap, tastes the same, and preserves the environment, will people actually eat meat grown in a lab?

Earth used to be purple, new NASA study shows

NASA research finds a new direction in searching for signs of life in the Universe.

  • NASA-funded research says retinal, not chlorophyll, gave the early Earth its color
  • The two pigments co-evolved but retinal came first
  • We should be looking for retinal-based life throughout the Universe
