Wallops Collaborates on Groundbreaking Super Pressure Balloon Test Flights

NASA’s Scientific Balloon Program has returned to Wānaka, New Zealand, for two scheduled flights to test and qualify the agency’s super pressure balloon technology. These stadium-sized, heavy-lift balloons will travel the Southern Hemisphere’s mid-latitudes for planned missions of 100 days or more. 

Launch operations are scheduled to begin in late March from Wānaka Airport, NASA’s dedicated launch site for mid-latitude, ultra long-duration balloon missions.  

“We are very excited to return to New Zealand for this campaign to officially flight qualify the balloon vehicle for future science investigations,” said Gabriel Garde, chief of NASA’s Balloon Program Office at the agency’s Wallops Flight Facility in Virginia. “Our dedicated team both in the field and at home has spent years in preparation for this opportunity, and it has been through their hard work, fortitude, and passion that we are back and fully ready for the upcoming campaign.” 

While the primary flight objective is to test and qualify the super pressure balloon technology, the flights will also host science missions and technology demonstrations. The High-altitude Interferometer Wind Observation (HIWIND), led by High Altitude Observatory, National Center for Atmospheric Research in Boulder, Colorado, will fly as a mission of opportunity on the first flight. The HIWIND payload will measure neutral wind in the part of Earth’s atmosphere called the thermosphere. Understanding these winds will help scientists predict changes in the ionosphere, which can affect communication and navigation systems. The second flight will support several piggyback missions of opportunity, or smaller payloads, including: 

  • Compact Multichannel Imaging Camera (CoMIC), led by University of Massachusetts Lowell, will study and measure how Earth’s atmosphere scatters light at high altitudes and will measure airglow, specifically the red and green emissions.  
  • High-altitude Infrasound from Geophysical Sources (HIGS), led by NASA’s Jet Propulsion Laboratory and Sandia National Laboratories, will measure atmospheric pressure to collect signals of geophysical events on Earth such as earthquakes and volcanic eruptions. These signals will help NASA as it develops the ability to measure seismic activity on Venus from high-altitude balloons.   
  • Measuring Ocean Acoustics North of Antarctica (MOANA), led by Sandia National Laboratories and Swedish Institute of Space Physics, aims to capture sound waves in Earth’s stratosphere with frequencies below the limit of human hearing.
  • NASA’s Balloon Program Office at the agency’s Wallops Flight Facility is leading two technology demonstrations on the flight. The INterim Dynamics Instrumentation for Gondolas (INDIGO) is a data recorder meant to measure the shock of the gondola during the launch, termination, and landing phases of flight. The Sensor Package for Attitude, Rotation, and Relative Observable Winds – 7 (SPARROW-7), will demonstrate relative wind measurements using an ultrasonic device designed for the balloon float environment that measures wind speed and direction.
