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.

Years ago, I read a bit of advice in The Whole Earth Catalog, which said a great way to get up to speed on a subject you are interested in is to read a children’s book about it. It’s excellent advice, and I’ve made use of it many times over the years. The best children’s […]
Translating abstract scientific data into sound can give researchers new insight into the complexities of the phenomena they are studying. MIT materials science professor and musician Markus Buehler, who has employed this technique to understand biological materials and develop new proteins, has now transformed the novel coronavirus into music. For the recording above, Buehler selected […]
Tonight’s full Moon is a “Pink Moon” aka “Passover Moon” aka “Paschal Moon” aka “Hanuman Jayanti” aka supermoon, the largest full moon of 2020. From NASA: The term “supermoon” was coined by the astrologer Richard Nolle in 1979 and refers to either a new or full Moon that occurs within 90% of perigee, its closest […]
In baseball, utility players often stay employed almost exclusively because of their versatility, their ability to slide effortlessly into a variety of needed roles and remain productive. Your current tech setup doesn’t need to work any differently — except that tech items are usually created to fulfill just one purpose. But if you want a […]
While all the downsides of stay-at-home orders and social distancing are evident, there are at least a few small silver linings to come out of all this. For many, this time spent indoors has meant a happy reintroduction to your very own kitchen. You know your kitchen. It’s usually the place that holds all your […]
Have you ever had more time to hone in on fine details than right now? Sure, at first glance, this might not seem like the time to get tripped up on the nitty-gritty of minutia. But how often are you ever going to have this much time to really stop and think about hows and […]
