After years of tests and development, NASA’s Balloon Program team is on the cusp of expanding the envelope in high-altitude, heavy-lift ballooning with its super pressure balloon technology. NASA’s scientific balloon experts are in Wanaka, New Zealand, prepping for the fourth flight of an 18.8 million-cubic-foot (532,000 cubic-meter) balloon, with the ambitious goal of achieving an ultra-long-duration flight of up to 100 days at mid-latitudes. Shown here, a NASA Super Pressure Balloon takes flight in 2015. When fully inflated, the balloon is as large as a football stadium. Happy #technologyTuesday everybody!
