Feb. 4, 2013 — A large NASA science balloon has broken two flight duration records while flying over Antarctica carrying an instrument that detected 50 million cosmic rays.
The Super Trans-Iron Galactic Element Recorder (Super-TIGER) balloon launched at 3:45 p.m. EST, Dec. 8 from the Long Duration Balloon site near McMurdo Station. It spent 55 days, 1 hour, and 34 minutes aloft at 127,000 feet, more than four times the altitude of most commercial airliners, and was brought down to end the mission on Friday. Washington University of St. Louis managed the mission.
On Jan. 24, the Super-TIGER team broke the record for longest flight by a balloon of its size, flying for 46 days. The team broke another record Friday after landing by becoming the longest flight of any heavy-lift scientific balloon, including NASA's Long Duration Balloons. The previous record was set in 2009 by NASA's Super Pressure Balloon test flight at 54 days, 1 hour, and 29 minutes.
"Scientific balloons give scientists the ability to gather critical science data for a long duration at a very low relative cost," said Vernon Jones, NASA's Balloon Program Scientist.
Super-TIGER flew a new instrument for measuring rare elements heavier than iron among the flux of high-energy cosmic rays bombarding Earth from elsewhere in our Milky Way galaxy. The information retrieved from this mission will be used to understand where these energetic atomic nuclei are produced and how they achieve their very high energies.
