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.

Here’s the first 14 of 100 proofs that the Earth is a globe, with the rest still to come author David Morgan-Mar. [via] 1. The Blue Marble The most straightforward way to check the shape of the Earth is to look at it. There’s one small problem, though. To see the shape of the Earth […]
Last month, Israeli non-profit SpaceIL’s Beresheet probe made it to the lunar surface but sadly it wasn’t a soft landing. Beresheet was the first private attempt at a lunar landing and they got pretty damn close. A couple weeks after the crash, NASA’s Lunar Reconnaissance Orbiter orbited over the area and NASA has released images […]
CBD is definitely screaming up toward the peak of inflated expectations, but it's not pure grift: the actual molecule and the way it interacts with our bodies is pretty amazing.

Kudos to those of us who have chosen a less wasteful third option to “paper or plastic” at the supermarket or club stores. Tote bags are reusable, but they can be a pain to tote around. Here’s an upgrade to that planet-saving measure. The Club Cart Lotus Trolley Bag is that rare tote you’ll want […]
