The US Space Force has embarked on a research initiative to better understand the effects of sonic booms caused by space launches. The effort aims to strike a balance between advancing space exploration and minimizing environmental and community concerns.
Led by Colonel Mark Shoemaker, the Space Launch Delta 30 commander, the research collaboration involves multiple partners including NASA, SpaceX, Brigham Young University, California State University-Bakersfield, and the Federal Aviation Administration.
The goal is to develop a comprehensive understanding of acoustic shock waves generated by rockets, which differ from those produced by aircraft due to their unique flight path and rapid acceleration.
A network of 25 high-tech monitoring stations has been deployed across 500 square miles in California’s central coast, capturing data on sonic boom patterns created by rockets launched from Vandenberg Space Force Base.
The research team, led by Kent Gee from Brigham Young University, is working to create a three-dimensional map of sound to understand how launches impact different areas.
Data collected so far has yielded surprising results, including variability in noise levels despite similar flight paths. The team is working to unravel the complex interplay between rocket trajectories, weather conditions, and topography.
Prior to launch, data models are analyzed to predict noise impact, while after launch, the team validates predictions using data from monitoring stations. This process guides future improvements and adjustments aimed at reducing potential disturbances.
To minimize sonic boom disruptions, the US Space Force is selecting launch times during less impactful hours of the day whenever possible. However, some launches must occur at night due to satellite placement requirements.
An Interagency Environmental Working Group brings together representatives from various agencies to share information and discuss data related to coastal resource impacts. The group recently reviewed findings from the collaborative sonic boom study.
Central Coast residents have expressed concerns over frequent sonic booms caused by rocket launches at Vandenberg Space Force Base, citing issues such as noise disturbance, structural integrity, and potential effects on wildlife and air quality.
The US Air Force has held public meetings to address community concerns. The research initiative aims to strike a balance between advancing space exploration and addressing local anxieties.
