Volans4Volans 4 was our fourth attempt at sending up a high altitude helium balloon and retreiving it. And for once were were successful. It was launched from Ithaca, NY on June 15, 2010 at aproximately 6:22pm on a party cloudy day, surface winds below 3 mph. Perfect! This was our first launch with a large payload. We had no problems until the power supply to the tranceiver in the chase vehicle failed about 45 minutes into the flight. By the time we found a replacement unit, we received a signal from the backup transmitter (a Motorola i570 using some custom software and Boost Mobile service) that the balloon had landed, prematurely I might add. At the time of the power failure, the payload had reached 31,575 feet above sea level. It came to rest at the Ford Hill Country Club (-75.980075, 42.315376) and was picked up by some golfers.
PayloadOur payload weight came to 2 pounds, 2.7 ounces.
