WANAKA, New Zealand – NASA successfully launched a super pressure balloon (SPB) from Wanaka Airport, New Zealand, at 11:35 a.m. Tuesday, May 17, (7:35 p.m. EDT Monday, May 16) on a potentially record-breaking, around-the-world test flight.
The purpose of the flight is to test and validate the SPB technology with the goal of long-duration flight (100+ days) at mid-latitudes. In addition, the gondola is carrying the Compton Spectrometer and Imager (COSI) gamma-ray telescope as a mission of opportunity.
“The team performed a brilliant launch operation today,” said Debbie Fairbrother, NASA’s Balloon Program Office chief. “The balloon is pressurized, healthy, and well on its way for this important test mission. I’m extremely proud of our Columbia Scientific Balloon Facility (CSBF) team for yet another beautiful launch, and I’m thankful for the tremendous support from our Kiwi friends, particularly the phenomenal Wanaka Airport staff.”
Two hours and 8 minutes after lift-off, the 532,000-cubic-meter (18.8-million-cubic-foot) balloon reached its operational float altitude of 33.5 kilometers (110,000 feet) flying a trajectory taking it initially westward through southern Australia before entering into the eastward flowing winter stratospheric cyclone. NASA estimates the balloon will circumnavigate the globe about the southern hemisphere’s mid-latitudes once every one to three weeks, depending on wind speeds in the stratosphere.
