These infrasound sensors can help determine falling space objects' trajectory using a method known as triangulation that compares signals received by two or more sensors to establish the location ...

Faint booms from space help track incoming debris. But the path matters more than you think. Earth gains a little mass each year as space dust rains down from above, adding thousands of metric tons to ...

Traditionally, infrasound is detected by ground-based sensor arrays, which don't cover the open ocean and can be muddled by other noises, such as the wind.

Experiments conducted high in the skies over New Mexico suggest that balloon-borne sensors could be useful in detecting the infrasound signals generated by small, extraterrestrial debris entering ...

Giant solar balloons were sent 70,000 feet up in the air to record sounds of Earth’s stratosphere. The microphones picked up aircraft, thunder, explosions, colliding ocean waves, as well as some ...

Infrasound is low frequency sound with a range of less than 10 Hz. The blast was detected by 17 infrasound stations in the CTBTO’s network, which tracks atomic blasts across the planet.
