Space travel takes a really long time. And if we ever want to visit  a planet other than Earth, we’re going to need a way  to keep people physically and mentally healthy for those long-haul trips.

00:10

To get around this problem,  science fiction writers sometimes place their fictional spacefarers in some sort of stasis or suspended animation.

00:18

And while we don’t have that –  yet – some researchers see it as the most viable way to get  us from place to place in space.

00:24

They’re taking inspiration from a natural process that occurs in other animals: hibernation.

00:28

But to pull it off, they’ll  need to figure out how to get around the ways our own bodies  keep themselves running.

[♪INTRO]

00:37

Even travelling to other planets within our solar system would take months or years.

00:41

In the best-case scenario,  with our current technology, a trip to Mars would take about 7 months each way.

00:47

Supporting astronauts on such lengthy missions will require lots of supplies.

00:51

They’ll need to bring their own food, water, air and medical equipment.

00:55

That’s a lot of luggage to load onto your spaceship, but not a lot of space.

01:00

So to conserve some of these limited resources, some researchers are looking for ways to mimic hibernation in humans.

01:06

During periods where resources are scarce, some animals cope by slowing their metabolism.

01:10

That way, they don’t consume  as much of, well, anything.

01:14

They don’t breathe as often,  their body temperatures drop, and they don’t need to eat  or drink or poop as much.
