NASA Deploys High-Altitude WB-57 Jets and Sensors During 2026 Eclipse
NASA utilized WB-57 high-altitude aircraft and scientific balloon arrays during the August 2026 total solar eclipse to gather crucial coronal and atmospheric data, advancing predictive models for space weather and ionospheric communications impacts.
During the August 12, 2026, total solar eclipse spanning Greenland, Iceland, and northern Spain, NASA deployed specialized high-altitude research platforms and scientific sensing payloads—including WB-57 high-altitude research jets and a nationwide balloon network—to collect environmental and solar observations. Operating within the path of totality, the WB-57 platform chased the lunar shadow to capture high-resolution visible and infrared imagery of the Sun's outer atmosphere, known as the corona. These observations captured detailed dynamics of solar prominences, which are super-hot plasma structures anchored in the Sun's complex magnetic field that extend hundreds of thousands of kilometers into space.
Understanding coronal plasma behavior and magnetic dynamics is essential for national defense, space domain awareness, and satellite system survivability. Solar prominences and associated solar activity generate severe space weather events, including coronal mass ejections and high-energy particle streams. These phenomena directly threaten military and commercial space architecture by causing electronic surface charging, satellite drag, single-event upsets, and severe degraded states across Global Positioning System (GPS) navigation signals and satellite communications links. High-altitude sensor deployments during total solar eclipses allow researchers to observe low-corona structures usually obscured by intense solar glare, delivering baseline data required to advance predictive space weather models relied upon by the U.S. Space Force and defense operators.
