Building a Better Space Suit

To put astronauts on the moon and Mars, NASA needs a new EVA suit — the first in 40 years. Here’s what the suit needs to do and how it’s being designed.

NASA’s “Biomimicry” Z-2 prototype suit cover layer draws from an environment with many parallels to the harshness of space: the world’s oceans. Mirroring the bioluminescent qualities of aquatic creatures found at incredible depths, and the scaly skin of fish and reptiles found across the globe, this design reflects the qualities that protect some of Earth’s toughest creatures.
