Travelling to space is just about the most epic thing a person can do, but it does come with some pretty serious consequences. There is a reason that Earth is the only place in the entire universe known to harbor life: It takes a very specific set of circumstances for an organism to survive, and space checks none of the boxes. Thanks to incredible technological advancements, we've been able to create survivable environments beyond Earth's surface, like the International Space Station (ISS) and the Space Shuttle Program, but these spaces are still a far cry from terra firma, and that presents a number of risks.

In space, astronauts are deprived of Earth's gravity, its atmosphere, and its magnetic field, which shields the planet's population from cosmic radiation. Life on the ISS lacks many of the amenities we typically rely on. There is limited space for exercise, the small sleep stations require sleeping upright, and NASA has banned astronauts from eating a number of foods on the ISS, leaving narrow options.
