Newman is developing the materials and the design for a space suit that astronauts could use to explore Mars or the moon. But if you've got the cash, you could sport one, too. As a space tourist, your suit would be fabricated right on-site. First, robotic arms pirouette around you, creating a 3-D laser scan of your body. Guided by that image, the arms extrude a liquid composite of Kevlar, spandex and nylon (over an insulating undergarment), which tightens as it cures, sort of like shrink-wrap. Materials integrated into the weave will actively control thermal regulation. Most of the suit's materials will be recycled when you are finished using it. A polymer torso shell serves as a docking point for your helmet and a frame for your oxygen tank--and maybe a holster for your digital camera. Newman's innovation is to use mechanical counterpressure to constrain your body's tissues, rather than a bulky layer of gas to pressurize the suit. By orienting the threads along something called the body's lines of non-extension, she can make the suit extremely tight yet highly flexible. Thus far, Newman has been able to create a sleeve around one leg that applies the appropriate mechanical counterpressure.
