Launch Attempt Scheduled for NASA Super Pressure Balloon
NASA is targeting Friday, April 21 (Thursday, April 20 in U.S. Eastern Time (EDT)), to conduct a super pressure balloon
(SPB) test flight launching from Wanaka Airport, New Zealand, on a potential 100-day journey.
NASA will begin flight preparations in the early morning hours Friday and will continue to evaluate real-time and
forecast weather conditions throughout the morning. If weather is conducive for launch, lift-off is scheduled between 8
and 11:30 a.m. locally (between 4 and 7:30 p.m. EDT Thursday, April 20).
This is the sixth scheduled launch attempt for NASA's 2017 Wanaka Balloon Campaign. A fifth attempt April 17 ended due
to wind conditions (wind shear) that would not support moving forward with a launch attempt.

Height when fully inflated: 68.96 meters (233 feet)
Altitude at float: 33.5 kilometers (110,000 feet)
Amount of balloon film used to make the balloon (the film is polyethylene—the same material used in sandwich bags,
though our film is much stronger and more durable): 8.9 hectares (22 acres)
