Auroral Substorm Research Mission Set for Alaska
A significant scientific mission is on the horizon in Alaska, focused on investigating the effects of auroral substorms on the Earth’s upper atmosphere. This initiative will involve the launch of three rockets within a brief timeframe to study air movement and compositional changes at high altitudes. Researchers aim to discern whether the heat generated by auroras causes vertical airflow or if energy is dispersed more broadly through wave activity. The insights gained from this research could enhance space weather forecasting, which is vital for the functioning of satellites and communication technologies.
Study Objective and Launch Plan
As detailed in the NASA reports regarding the experiment titled Auroral Waves Excited by Substorm Onset Magnetic Events (AWESOME), the rocket launches will take place at the Poker Flat Research Range. This facility, situated approximately 20 miles north of Fairbanks, is operated by the University of Alaska Fairbanks under a contract with NASA. The launch window is scheduled from March 24 to April 6.
The mission will utilize a four-stage rocket and two two-stage rockets. The first two rockets will deploy tracers at predetermined altitudes to analyze wind patterns. Following this, the third rocket will release vapor tracers at five different heights. These tracers, which will be colored pink, blue, and white, are expected to remain visible for up to 20 minutes, allowing ground-based cameras to capture the data under optimal lighting conditions.
Scientific Goals and Observations
Leading the project is Mark Conde, a space physics professor at the University of Alaska Fairbanks. The primary objective of the experiment is to explore the influence of auroras on atmospheric dynamics. One prevailing hypothesis suggests that vertical convection is a significant factor, whereas an alternative theory posits that acoustic-buoyancy waves may exert a more widespread effect on the atmosphere. This research has the potential to enhance current scientific understanding and improve existing models related to space weather.
A dedicated team of graduate researchers will be observing the launches from various Alaskan locations, including Utqiagvik, Kaktovik, and Toolik Lake. The outcomes of this study may yield valuable insights into how auroral events modify atmospheric conditions and affect technology reliant on satellite systems.
