When Neil Armstrong and Buzz Aldrin first stepped on the Moon, it changed history.  Now, NASA is aiming even bigger.

The Artemis program plans to build a Moon base by the 2030s.  And they want to use things like lunar soil and frozen water to support long-term life.

But here's where it gets wild.  Living in space changes us.

Astronaut Scott Kelly lived in space for almost a year.  And when he came back, he showed major biological shifts . . . even changes to his genes.  On top of that, there's higher levels of radiation on the Moon, which we could pass down to future generations.

Over time, humans could evolve differently . . . just like animals on isolated islands.  And eventually, those differences could be big enough to create an entirely new human species.
