As his Red Bull Stratos freefall from the edge of space looms ever nearer, mission pilot Felix Baumgartner conceded for the first time that he does experience moments of anxiety. However, the 41-year-old Austrian finds reassurance in the kind of engineering details shared today at Sage Cheshire Aerospace, where the Red Bull Stratos science team introduced prototype technology aimed at taking him to the edge of space at 120,000 feet, and bringing him back to Earth – hopefully as a new record holder, but most importantly, safe and sound.Besides Baumgartner’s “second skin” space suit, the components necessary to safely complete a freefall from 120,000 feet include: a mammoth helium balloon; a pressurised capsule; a chest pack with monitoring, tracking and communications capabilities; and a personal parachute system unlike any other in existence. www.redbullstratos.com
