Can We Still Go to Mars?
Elsewhere in the solar system, a NASA rover is on its way to Mars. It carries, among other things, several pieces of spacesuit material. Designers want to see how the samples fare in the planet’s dusty, radiation-laden environment—the sturdy fabrics of the suit’s exterior, the cut-resistant fibers of its gloves, the shatterproof plastic of the bubble helmet that might someday reflect the soft light of a Martian sunset.
