1,700km Away: Rocket Blast Detected
Blue Origin's New Glenn explosion picked up by infrasound analysis, a game-changer for launch safety monitoring
A recent explosion of Blue Origin's New Glenn launch vehicle during a static test fire in May 2026 was detected from up to 1,700 kilometers away using infrasound analysis. This technique, which involves measuring low frequency soundwaves below the range of human hearing, has been used to confirm the time and location of the explosion and estimate the yield of the blast.
The explosion, which involved liquid oxygen and liquid methane propellant, generated infrasound signals that were picked up by a network of broadband microbarometers. Researchers at Sandia National Laboratories analyzed these signals, along with time-stamped video of the accident, to determine the exact time and location of the explosion at Cape Canaveral.
The yield of the explosion was estimated to be 0.131 kilotons TNT-equivalent, providing valuable information on the infrasound signals produced by liquid oxygen/liquid methane propellant. This is significant, as such observations are still limited, with most existing information coming from smaller experiments or historical tests involving different propellant systems.
The use of infrasound analysis in this case demonstrates its potential in monitoring launch anomalies. The Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTO) already uses infrasound as one of its main monitoring techniques to detect nuclear test explosions. In this instance, data from 36 regional stations were back-projected to confirm the time and location of the explosion.
## Why it matters The ability to detect rocket accidents from a distance of up to 1,700 kilometers has significant implications for launch safety monitoring. As the space industry continues to grow, the need for effective monitoring systems to detect and respond to accidents becomes increasingly important. Infrasound analysis could play a key role in this effort, providing a means of quickly and accurately detecting launch anomalies and minimizing the risk of damage or injury.
The fact that the New Glenn explosion was detected from such a great distance highlights the potential of infrasound analysis in this context. As researchers continue to develop and refine this technique, it could become an essential tool in the monitoring of launch safety, helping to prevent accidents and ensure the safe operation of launch vehicles.
