Pain is an indispensable tool for survival. The prick of a nail underfoot is a warning that protects you from a deep, dirty wound—and maybe tetanus. The sizzle of a steel skillet is a deterrent against a third-degree burn. As much as it sucks, pain, oddly enough, keeps us from hurting ourselves. It's a luxury that prosthetic users don’t have.

Small satellite makers have promised to do a lot of things: change the way we communicate, change the way we see our planet, change the way we predict the weather.

Consider the rotten strawberry. Sitting there in your fridge, it suffers a cascading trifecta of maladies: For one, it dehydrates. Two, oxygen seeps in.

In the early Space Age, the people who sent up satellites could operate under what's known as "big sky" theory. Space is so vast, so spacious, that we could never possibly use it all up. History, however, has repeatedly shown that whenever we think something is too abundant for humans to deplete, we're wrong.

As Hurricane Maria approached Puerto Rico in late September 2017, planetary scientist Ed Rivera-Valentin knew he needed to get out.
