NASA just launched two rockets from Alaska to explore the fascinating world of auroras, those beautiful light displays seen in the northern skies. These exciting missions aim to understand the electrical “circuitry” that creates these vibrant visuals, which occur when solar winds hit our atmosphere.
The rockets took off from Poker Flat Research Range, near Fairbanks, Alaska. They are known as sounding rockets, and they’re equipped to gather crucial data during their brief flights into the atmosphere.
One of the notable missions, called the Black and Diffuse Auroral Science Surveyor (BADASS), launched early on February 9. Its goal was to study black auroras, which happen when electrons shoot off into space instead of heading towards Earth. This unique behavior sets black auroras apart from regular ones.
The BADASS mission reached an impressive altitude of 224 miles (360 km) before returning to Earth. Marilia Samara, the mission’s lead investigator, confirmed that everything went smoothly. The scientific instruments worked well and delivered high-quality data, helping NASA understand what causes the reversal of electron streams.
The second mission, called the Geophysical Non-Equilibrium Ionospheric System Science (GNEISS), also launched on February 10. With a clever approach, it sought to create a detailed “CT scan” of the electric currents flowing within the auroras. The GNEISS rockets reached altitudes of 198 miles (319 km) and collected significant data about how electricity behaves in that region.
Kristina Lynch, GNEISS’s lead investigator and professor at Dartmouth College, explained, “We want to know how the current spreads downward through the atmosphere.” By using two rockets and ground receivers, this mission aims to produce a three-dimensional view of the aurora’s electric environment. Lynch likened it to performing a CT scan of the plasma beneath the auroras.
Understanding auroras is crucial. They are linked to geomagnetic storms, which can disrupt technological systems, affect satellite operations, and even pose risks to astronauts. Back on Earth, these storms can lead to power outages, cause flight delays, and interfere with radio signals.
Recent research indicates that geomagnetic storms are becoming more frequent due to rising solar activity, making the study of auroras more relevant than ever. According to the NASA report, we’ve seen a noticeable increase in the severity and frequency of these storms in recent years. This growing pattern highlights the importance of missions like BADASS and GNEISS, as they provide insights critical for technology and safety in both space and on Earth.
As scientists continue to unravel the mysteries behind auroras, one thing is clear: these stunning light displays are not just a beautiful phenomenon; they are key indicators of our planet’s interactions with space weather.
