BEAR 3 balloon was launched Tuesday evening May 26 @ 8:15 PM local time (UTC: May 27 @4:14 ) in a almost clear and wind-less sky. We watched in awe as the balloon went vertically above us and stayed there for almost the entire upward flight. From our launch facility located at Poker Flats Rocket Range, you could look up and see both the balloon and the radar reflector even when it reached an altitude of 30,000 feet. BEAR 3 continued its almost perfect and vertical flight until 86,518 feet, then burst and began its descent, finally drifting a bit to the northwest. Upon balloon burst, our pilot Myles (KL1NU), Neal (WL7NZ) and Dan (KL1JP) took flight in Myles' plane to give chase and record the descent and touchdown. They chased the balloon for almost 30 minutes, spiraling around and downward, amazed at the sight of a fully deployed and perfectly descending parachute, observing and photographing the descent and touchdown location. The June 1 recovered gps data confirmes the revised altitude of 86,518 feet. Data indicates the ascent time was 1hr 52min while descent time was 46min with a total flight time of 2hr 37min. We will be adding photographs, data and information for the next week, including still pictures, movies, data and hopefully photo-micrographs of volcanic ash from the on-board payloads.

If you think we've been sitting around twiddling our fingers all winter, think again... We've spent time testing equipment (see Design here) at minus 40F outside using the extreme Fairbanks winter temperatures as a near-space proving ground. We've put together a bunch of capsules ready for "your" science experiments. We've put together a new and hopefully more stable camera platform and... we've begun planning for the 2009 BEAR flights, including construction of a high-altitude particle sampler (by University of Alaska EE/ME students) capable of capturing Mt. Redoubt volcanic ash.

Interested In Helping With BEAR Balloon Flights? We are actively looking for interested people who want to contribute their time and skill or enthusiasm by helping put together all the parts necessary to fly the BEAR 4 and BEAR 5 balloons. There's plenty of work to go around...
