WĀNAKA, New Zealand — NASA is targeting Sunday, April 16 (Saturday, April 15 in the United States), to conduct a super pressure balloon (SPB) test flight launching from Wānaka Airport, New Zealand, to further test and qualify the technology, which can offer cost savings compared to space missions. This first launch will also carry the Super Pressure Balloon Imaging Telescope (SuperBIT), from Princeton University.
“We are excited to be back in Wānaka for two planned balloon missions set to qualify this game-changing technology that enables long-duration flight in a near-space environment for the science community,” said Debbie Fairbrother, NASA’s Balloon Program Office chief. “A lot of different weather factors need to line up to support a launch attempt, and so far, Mother Nature is cooperating with us nicely for this first opportunity.”
For subsequent launch attempts, if needed, NASA will announce by 2 p.m. NZST (10 p.m. EDT) if the next day’s forecast weather will support a launch attempt.
For launch, winds need to be light and flowing in a reliable direction both at the surface and at low levels up to about 1,000 feet (300 meters). Winds flowing in opposite directions on the ground and lower levels could have a shearing effect on the balloon. In addition, NASA monitors for favorable stratospheric wind conditions at 110,000 feet (33.5 km), which is where the balloon will float.
After launch the 18.8-million-cubic-foot (532,000 cubic-meter) SPB will ascend to its float altitude where the stratospheric winds will propel it at speeds up to and exceeding 100 knots on a weeks-long journey around the southern hemisphere.
