Mars has been seeing a lot of action lately, between NASA’s string of rovers and new projects from Elon Musk and Mars One. But what would it take to set up a permanent settlement there? Could humans survive in such a harsh and alien setting? In this week’s Big Future, Adrianne Jeffries takes a look at the nuts and bolts of a martian settlement, from food shipments to radiation management. There are a lot of problems, but we’ve got good ideas about how to solve them.

Can we colonize Mars?

Kryptonite seems fantastically improbable. Superman’s greatest weakness, as everyone knows, is his own former home planet: After it exploded, Krypton’s fragments passed through a “cloud of radiation” that transformed them into the familiar glowing green substance that is highly lethal to Superman, though apparently not immediately harmful to ordinary humans or other terrestrial life forms.

"Everything the Note 4 shoots looks great, too. Photos are crisp and clean and accurate; the Note 4’s dynamic range doesn’t quite match the iPhone 6’s, but I rarely took a shot I didn’t like. Built-in optical image stabilization makes shooting easier in low light, too. The Note’s autofocus can be a touch unreliable, but the high-res display makes for such a crisp viewfinder that I always noticed and corrected the problem before missing the shot. All things considered, the Note 4 is easily among the best Android cameras I’ve used. It’s not leaps and bounds beyond its competitors, but it’s an excellent, reliable camera."
