A NASA rocket mission launching from Alaska seeks to unravel the complex electrical circuits behind the aurora borealis, employing a technique akin to a CT scan to map the flow of electrical currents within the stunning displays. The GNEISS mission, launching from Poker Flat Research Range near Fairbanks, will release subpayloads to measure the electrical currents. Scientists aim to understand how the currents close within the auroral circuit.
The Poker Flat Research Range in Fairbanks, Alaska, is a crucial site for studying the aurora, due to its strategic location under the auroral oval. The range provides access to sophisticated infrastructure and support for scientific missions, making it the ideal base for the GNEISS and Black and Diffuse Aurora Science Surveyor missions.
The GNEISS mission will help improve our understanding of the way in which the auroral current flows, and in the future, these findings could be used to enhance the accuracy of auroral predictions and improve the protection of technological infrastructure from space weather. The use of radio signals to map plasma density is a groundbreaking approach, providing an innovative way to probe the intricate electrical processes at play in the aurora. The simultaneous launch of the GNEISS and the Black and Diffuse Aurora Science Surveyor missions allows scientists to investigate multiple aspects of the aurora simultaneously, fostering a more complete picture of this dynamic phenomenon. All of these factors combined lead to this important mission, which could happen as soon as the weekend
