The ethereal dance of the aurora borealis, too known as the Northern Lights, has captivated humanity for centuries. Now, NASA is taking a deeper dive into the science behind this spectacular phenomenon, launching a series of rocket missions from Alaska to study the complex electrical circuitry that powers these displays. These missions aim to improve our understanding of space weather and its potential impact on technology both in space and on Earth.
Two sounding rockets were launched from the Poker Flat Research Range near Fairbanks, Alaska, on February 9th and 10th, initiating a unique investigation into the aurora’s electrical behavior. The research focuses on understanding how energy from the sun interacts with Earth’s atmosphere, creating the vibrant light shows and, crucially, the electrical currents that flow within them. This research is particularly important as these currents are linked to geomagnetic storms, which can disrupt satellite operations, power grids and communication systems.
One of the missions, the Black and Diffuse Auroral Science Surveyor (BADASS), launched in the early morning of February 9th, reaching an altitude of 224 miles (360 km) before returning to Earth. According to mission principal investigator Marilia Samara, the mission proceeded as planned, with scientific instruments returning high-quality data to study “black auroras” – a peculiar event where electrons are propelled upwards into space rather than towards our planet. Space.com reports that this data will help scientists understand the reversal of electron streams that cause these unusual auroras.
The second mission, the Geophysical Non-Equilibrium Ionospheric System Science (GNEISS) mission – pronounced “nice” – employed a pair of rockets launched back-to-back on February 10th, reaching peak altitudes of 198 miles (319 km) each. GNEISS aims to create a three-dimensional “CT scan” of the electrical currents flowing within the northern lights. Kristina Lynch, the GNEISS principal investigator and a Dartmouth College professor, explained in a NASA statement, “We want to know how the current spreads downward through the atmosphere.”
Mapping the Aurora’s Electrical Flow
The GNEISS mission utilizes a network of ground receivers in conjunction with the data collected by the rockets to build a comprehensive picture of the aurora’s electrical environment. Lynch likened the process to performing a “CT scan of the plasma beneath the aurora,” allowing researchers to visualize the complex interplay of charged particles. This detailed mapping is crucial for understanding how auroral substorms – disturbances in the Earth’s magnetosphere – affect the upper atmosphere.
Understanding these processes isn’t merely an academic exercise. Auroras are intrinsically linked to geomagnetic storms, which can have significant consequences for our increasingly technology-dependent world. These storms can disrupt satellite functionality, posing risks to communication, navigation, and weather forecasting systems. They also present a hazard to astronauts in space and can even induce power outages and interfere with radio transmissions on Earth. Fox Weather highlights the importance of this research in mitigating these risks.
The AWESOME Mission and Previous Research
These recent launches build upon previous work conducted at the Poker Flat Research Range. In March 2025, NASA completed the AWESOME mission, which involved launching three rockets to study the impact of auroral substorms on the upper atmosphere. Although one of the rockets experienced an issue with its tracer release system, the mission still yielded valuable data. The University of Alaska Fairbanks Geophysical Institute reported that the vapor trail, despite the issue, was still usable and likely met mission success criteria.
The ongoing research into auroral electrical circuits represents a significant step forward in our understanding of space weather and its potential effects on Earth. By employing innovative techniques like the “CT scan” approach of the GNEISS mission, scientists are gaining unprecedented insights into the complex processes that govern these mesmerizing displays. As our reliance on space-based technologies continues to grow, this research will become increasingly vital for protecting our infrastructure and ensuring the continued functionality of essential services.
The data collected from these missions will be analyzed in the coming months, and researchers anticipate publishing their findings in peer-reviewed scientific journals. Further missions and continued monitoring of auroral activity are planned to refine our understanding and improve space weather forecasting capabilities. What comes next will be a deeper analysis of the data, and hopefully, a more accurate model of the aurora’s electrical behavior.
