Tape Screech Demystified: Tiny Sonic Booms From Adhesive Cracks

Physicists explain Scotch tape’s open‑air screech as a sequence of tiny, sideways cracks in the adhesive that form as you peel. These cracks open nanoscopic gaps between tape and surface; air can’t rush in fast enough to fill them, so a pressure pulse travels with each crack to the tape’s edge and collapses into the surrounding air, producing the audible screech. High‑speed cameras and synchronized microphones linked each pulse to a crack reaching the edge. The same team noted earlier vacuum experiments can emit X‑rays with tape flown in a perfect vacuum, but the in‑air screech comes from the crack‑driven pressure pulses.

Earthquake sensors offer real-time tracking for reentering space junk

Researchers propose using a global network of seismic sensors to detect sonic booms from space debris as they reenter Earth, enabling reconstruction of their trajectories and potentially pinpointing where fragments might land. In a 2024 Shenzhou 17 module event, 127 California seismic stations recorded the sonic boom, revealing the debris path differed from orbital predictions and suggesting ground impact could occur between Bakersfield and Las Vegas; the approach could speed up locating debris and inform risk assessments, with future work expanding to acoustic sensors over oceans. The study, published in Science, highlights how quake networks could augment current radar/optical tracking in space situational awareness.

SpaceX Falcon 9 Launch From Vandenberg Promises Sonic Boom Across Central California

SpaceX will launch a Falcon 9 rocket from Space Launch Complex-4 at Vandenberg Space Force Base in Santa Barbara County between 8:18 p.m. and 8:53 p.m. on Friday, with a backup window at 8:04 p.m. Saturday if needed. The first-stage booster, making its second flight, will return to Landing Zone 4 about seven minutes after liftoff. The mission, designated NRL-105 for the National Reconnaissance Office, could produce a sonic boom audible across Santa Barbara, Ventura and San Luis Obispo counties and may be visible from parts of California; a live webcast is available at spacex.com, and local viewing spots around the Lompoc Valley are recommended.

SpaceX's Upcoming Vandenberg Launch to Deliver Italy's COSMO-SkyMed Satellite

A sonic boom advisory has been issued for a planned SpaceX Falcon 9 launch from Vandenberg Space Force Base on Saturday evening, targeting the COSMO-SkyMed Second Generation mission for the Italian Space Agency, with a backup launch opportunity on Sunday. The first stage of the rocket is expected to land back on Vandenberg, producing a sonic boom audible in surrounding communities.

Dazzling Meteor Lights Up Indiana's Morning Sky

Dazzling Meteor Lights Up Indiana's Morning Sky

A bright meteor, known as a fireball or bolide, was seen streaking across the sky over Indiana early Tuesday morning, despite cloudy conditions. The event was reported by 47 witnesses to the American Meteor Society, with some describing it as lighting up the sky like daylight. The fireball, which traveled south by southeast near Indianapolis, was captured on video by a resident, who also reported hearing a sonic boom. Such events, while rare to witness, occur regularly as meteors burn up in Earth's atmosphere.

SpaceX Starship's Sonic Booms Pose Structural Risk, Study Shows

SpaceX's Starship rocket, which aims for 100 launches a year, generates intense sonic booms that could damage nearby structures, according to recent research. The study, published in the Journal of the Acoustical Society of America, highlights the potential risk to areas near SpaceX's Starbase in Texas, such as Port Isabel and South Padre Island. The noise from Starship's launches is significantly louder than that of SpaceX's Falcon 9 and NASA's SLS rockets. Environmental concerns have also been raised, with lawsuits filed against the FAA for inadequate environmental review of the launch site.

Meteor Explodes Over NYC, Causes Shaking and Loud Booms

A meteor exploded over Manhattan after flying over the Statue of Liberty at a speed 58 times faster than a Boeing 737, causing loud booms heard in New York and New Jersey. NASA and other authorities are uncertain if the booms were caused by the meteor or military activity, but no damage or injuries were reported. Despite the dramatic event, many New Yorkers remained unfazed.
