NASA has embarked on an ambitious mission to unravel the mysteries of the black auroras, launching twin rocket missions from Alaska. These launches, part of the Black and Diffuse Auroral Science Surveyor (BADASS) and Geophysical Non-Equilibrium Ionospheric System Science (GNEISS) missions, aim to study the electrical 'circuitry' within auroras, the vibrant light displays that occur when solar wind collides with Earth's atmosphere. But here's where it gets controversial... The BADASS mission, which launched on February 9th, focuses on black auroras, where electrons shoot up into space instead of flowing towards Earth. This unique phenomenon, which occurs when electrons reverse their direction, is a subject of intense scientific interest. The GNEISS mission, launched on February 10th, takes a broader approach, aiming to create a 'CT scan' of the electric currents flowing in the northern lights. By using two sounding rockets and a network of ground receivers, researchers will gather data to create a three-dimensional view of an aurora's electrical environment. This study is crucial as auroras are associated with geomagnetic storms, which can cause technical issues for satellites and endanger astronauts. On Earth, these storms can lead to power blackouts, air travel diversions, and radio transmission interference. So, what do you think?
