MIT researchers are developing a "second skin" space suit lined with tiny coils that contract when switched on, tightening the garment around the body.
The coils (image below) in the "BioSuit" are made from shape-memory alloy that "remembers" its shape when bent and returns to its original form if heated.
“With conventional spacesuits, you’re essentially in a balloon of gas that’s providing you with the necessary one-third of an atmosphere [of pressure,] to keep you alive in the vacuum of space,” says Dava Newman, MIT professor of aeronautics and astronautics and engineering . “We want to achieve that same pressurization, but through mechanical counterpressure — applying the pressure directly to the skin, thus avoiding the gas pressure altogether. We combine passive elastics with active materials. … Ultimately, the big advantage is mobility, and a very lightweight suit for planetary exploration."

A superearth 111 light years away shows evidence of water vapor in its stratosphere, reports National Geographic. Water on another world. The discovery, announced this week in two independent studies, comes from years of observations of the exoplanet K2-18b, a super-Earth that’s about 111 light-years from our solar system. Discovered in 2015 by NASA’s Kepler […]
NASA announced today that the agency is moving ahead with a planned mission to Jupiter’s moon Europa. In this next phase, engineers will complete the final design, construction, and testing of the Europa Clipper spacecraft for a launch as soon as 2023. Why the icy moon Europa? From NASA: NASA’s Europa Clipper mission will conduct […]
Studies have shown cannabidiol (more popularly known as CBD) to be effective in two main areas: Pain relief and stress relief. Both of those make the non-psychoactive, cannabis-derived compound a natural for topical creams. There’s no shortage of CBD products out there, but here’s eight of our favorites, all specifically designed for dermatological use – […]
