For the first time, we can hear the "sounds" of wind on Mars as captured by the scientific instruments on NASA's InSight robotic lander. From NASA:
"Capturing this audio was an unplanned treat," said Bruce Banerdt, InSight principal investigator at NASA's Jet Propulsion Laboratory (JPL) in Pasadena, California...
Two very sensitive sensors on the spacecraft detected these wind vibrations: an air pressure sensor inside the lander and a seismometer sitting on the lander's deck, awaiting deployment by InSight’s robotic arm. The two instruments recorded the wind noise in different ways. The air pressure sensor, part of the Auxiliary Payload Sensor Subsystem (APSS), which will collect meteorological data, recorded these air vibrations directly. The seismometer recorded lander vibrations caused by the wind moving over the spacecraft's solar panels, which are each 7 feet (2.2 meters) in diameter and stick out from the sides of the lander like a giant pair of ears.

Scientists drilled into the Chixclub crater in the Gulf of Mexico to learn more about the end of the mesozoic era. They learned more than they expected, reports Katherine Kornei in The New York Times. The first day of the Cenozoic was peppered with cataclysms. When the asteroid struck, it temporarily carved a hole 60 […]
Get over it! Despite the mockers and complainers, and even attempts to make it illegal to perambulate while looking at your own damned phone, science concludes that the risks of it are negligible. As part of the mandated study, the DOT conducted an in-depth review of written crash narratives in the city between 2014 and […]
Typically, marine photography is done in rich, saturated color — the better to show off the riot of life beneath the waves. But the photographer Christian Vizl has done it in high-contrast black and white, producing eerily intense ways of re-seeing marine life. You can see the work on his site, and in his new […]
The field of data analytics can get intimidating, even for business professionals who constantly rely on it. But at its heart, its purpose is to simplify. To take mounds of information and distill their insights into a single clear picture. Currently, the go-to software for painting that picture is Tableau. And if you want to […]
If you’re in the market for a stable, durable camera fully suited for first-person video, there’s a good chance that you’re the adventurous type. So why settle on a familiar name like GoPro? The DJI Osmo Action 4K HDR Camera checks off all the same boxes on the action cam checklist as the GoPro 4K […]
The market for web developers is wide open these days. If only we could say the same about the pathway to that career. If you’re not already an experienced coder, it can be difficult to get things rolling. A four-year college degree or technical school? Sure, if you’ve got the money. What about web tutorials? […]
