New Insights on Auroras: NASAs Upcoming Rocket Launches in Alaska Aim to Unravel Atmospheric Mysteries

A significant operation is scheduled to occur in Alaska, focused on understanding the effects of auroral substorms on the upper atmosphere of Earth. In a brief time frame, three rockets will be launched to study air movement and compositional changes at elevated altitudes. Researchers aim to discover if the warmth generated by auroras leads to vertical air displacement or if the energy is distributed more widely through wave action. The outcomes could enhance the accuracy of space weather predictions, which are vital for satellite operations and communication networks.

Objective of the Study and Launch Schedule

Per the information regarding the Auroral Waves Excited by Substorm Onset Magnetic Events (AWESOME) project, launches are planned from the Poker Flat Research Range. This facility, situated 20 miles north of Fairbanks, operates under the management of the University of Alaska Fairbanks via a NASA contract. The launch period is from March 24 to April 6.

The operation will utilize a four-stage rocket and two two-stage rockets. The initial pair will deploy tracers at designated heights to analyze wind patterns. The third rocket is set to release vapor tracers at five varying altitudes. The tracers, appearing in pink, blue, and white, are expected to be observable for up to 20 minutes. Ground-based cameras will record the data based on specific lighting conditions.

Scientific Aims and Observations

Mark Conde, a professor specializing in space physics at the University of Alaska Fairbanks, is spearheading this initiative. The primary goal is to assess the influence of auroras on atmospheric movement. One hypothesis posits that vertical convection is significant, while another suggests that acoustic-buoyancy waves may cause a more widespread atmospheric impact. This investigation could alter current perspectives and refine space weather models.

A cohort of graduate students will oversee the launches from multiple locations across Alaska, such as Utqiagvik, Kaktovik, and Toolik Lake. The findings could yield improved understanding of how auroral phenomena affect atmospheric conditions and satellite-dependent technological systems.
