NASA launch attempt Fri 21 April
20 Apr 2017
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.
