NASA's scientific balloon test flight sets duration record
NASA's humongous scientific balloon didn't quite hit the agency's ultimate goal, but it still set a flight duration record after flying for 46 days, 20 hours and 19 minutes. The agency launched the 18.8-million-cubic-foot super pressure balloon (SPB) on May 16th to test how tough it is and to see if it can carry a scientific payload with no issues. Clearly, the test flight was a success: the agency's Balloon Program Office chief Debbie Fairbrother says it's "far and away the longest mid-latitude flight of a NASA heavy-lift balloon to date."
