NASA rocket to conduct CT scan of auroral electricity

The GNEISS mission launched two rockets back-to-back from Alaska on Feb. 10. Principal investigator Kristina Lynch reported that all ground stations, subpayloads, and booms functioned as expected and that the science team is pleased with the launch and the data collected so far. The mission uses two rockets flying side Kristina Lynch said the approach is essentially like doing a CT scan of the plasma beneath the aurora. She noted that the team is interested in how the current spreads downward through the atmosphere rather than just where the rocket flies. The mission combines in situ measurements with ground-based imagery to learn to read the aurora.
