Space exploration is continually growing, with time spent in space becoming longer and longer for astronauts. With that, though, come some serious repercussions, especially to astronauts' health.

With missions to the Moon and Mars upcoming, the push towards a better understanding of how space affects astronauts' bodies increases. Astronauts' brains, hearts, muscles, and bone mass all take their toll when they're up in microgravity environments.

Now, over 200 scientists came together to look into the matter and discovered that one biological molecule may lie behind all of these bodily changes in space — the mitochondria.
