If you're trying to figure out how best to measure human performance under extreme conditions, the skies are a great place to start. Not much pushes the body harder than space travel or extreme flight. Successful missions depend on knowing precisely how astronauts and pilots respond to huge physical strain, and that requires a level of real-time biometric tracking way beyond your average heart-rate chest strap. That's where wearable innovator LifeBEAM comes in. Founded in 2011, the New York-based business has spent years developing cutting-edge solutions that give NASA and the US Air Force mission-critical insights.
