Exploring Venus's Core with Floating Seismometers

Scientists from NASA's Jet Propulsion Laboratory and Sandia National Laboratory are proposing the use of seismometers hanging from high-altitude balloons to study the inner workings of Venus. Infrasound seismometers, which monitor infrasound pressure waves transmitted through a medium other than the ground, could pick up seismic activity in Venus' atmosphere. The high-altitude balloon would eliminate the need for materials that can survive on Venus' scorching surface. However, challenges remain, including the lack of successful balloon missions to Venus and the difficulty of validating seismic data without other sensors. Despite the potential, there are currently no plans for a mission utilizing this technology.

Unexplained, eerie sounds detected in Earth's atmosphere by balloon sensors.

Scientists have recorded eerie sounds in Earth's stratosphere using hot air balloons fitted with microbarometers. The sounds, which repeat a few times per hour, are in the infrasound range and have unknown origins. The balloons, made from common materials, can soar around 70,000 feet over Earth and could potentially be used for more complex missions in the future. The researchers plan to continue investigating the collected data to determine the source of the mysterious noises.

Unexplained Stratospheric Noises Detected by Solar Balloons

Researchers from Sandia National Laboratories in New Mexico have used solar-powered balloons to capture mysterious sounds in Earth's stratosphere, including thunder, ocean waves colliding, propeller aircraft, city sounds, suborbital rocket launches, earthquakes, and several unidentified noises. The balloons carried infrasound recorders up to 70,000 feet, and some of the mysterious infrasound signals occur a few times per hour during flights, but their source remains unknown.

Unexplained, mysterious sounds detected in Earth's stratosphere by solar-powered balloons.

Solar-powered balloons launched into the Earth's stratosphere have recorded a series of mysterious infrasound rumblings that scientists can't explain. The noises, detected by specialized instruments at 70,000 feet above the Earth's surface, have so far defied explanation. The researchers say they will continue to investigate the sounds in the stratosphere, tracing more sounds to their origin points and studying their variability across seasons and different regions of the world.

Mysterious Stratospheric Sounds Detected by Solar-Powered Balloons

Solar-powered balloons are recording mysterious sounds in the stratosphere, including the sound of distant thunderstorms, falling meteors, or turbulence. The balloons listen to the Earth from a dozen miles up, recording in infrasound, below the human hearing range. The sounds captured include the ocean waves, earthquakes, wind turbines, and a mysterious crackling that scientists can't identify yet. The world of infrasound is vast and largely unmapped, and almost every flight picks up unidentified sounds. Anyone can fly an eavesdropping balloon, and the more eyes in the sky, the more we learn.

Unexplained Sounds Detected in Earth's Stratosphere.

Solar balloons were sent 70,000 feet up in the air to record sounds of Earth’s stratosphere, and the microphones picked up some unexpected sounds. The balloons can take sensors twice as high as commercial jets can fly. The researchers tracked their balloons using GPS, since they can travel for hundreds of miles and land in inconvenient locations. The advantage of the high altitude reached by the balloons means that noise levels are lower and the detection range is increased — and the whole Earth is accessible.

Unexplained sounds detected in Earth's stratosphere by solar-powered balloons.

Solar balloons sent up to 70,000 feet in the stratosphere have recorded sounds including colliding ocean waves, thunder, earthquakes, and even unknown sounds. The balloons, built by researchers at Sandia National Laboratories, cost around $50 to make and can be assembled on a basketball court. The researchers attached microbarometers to the balloons to record low-frequency sounds, and GPS to track them. The researchers are investigating the soundscape of the stratosphere and trying to determine the origin of the rumbles. The balloons could one day be used to explore other planets.

Unexplained sounds detected in Earth's stratosphere perplex scientists.

Solar balloons sent up to 70,000 feet in the stratosphere have recorded a range of sounds, including colliding ocean waves and unidentified crackles and rustling. The balloons, which can carry sensors twice as high as commercial jets, were built by researchers at Sandia National Laboratories in New Mexico for around $50 each. The balloons are made of painter’s plastic, shipping tape and charcoal dust, and can be assembled on a basketball court. The researchers attached microbarometers to the balloons to record low-frequency sounds, and tracked them using GPS. The researchers are now trying to identify the signals recorded during the flights.
