Furthermore, while the bright red dust settles, dust devils can scour it away to expose darker sands beneath. Ultimate adds Steve from Minecraft, wrote atmospheric scientists Claire Newman, knocked out NASA's long-lived Opportunity rover. A bit of dust and wind won't phase it, and we can safely enjoy the views back here on Earth. Enhance! The best picture of Martian dust devils is this next one. 12:59 Why can gas giants remain spherical?

On February 1, InSight detected a wind vortex just before its two solar panels received bumps in power. InSight's weather sensors detected a drop in air pressure coinciding with a rise in wind speed, signaling a dust devil. "Stronger surface heating tends to produce stronger convection and convective vortices, which consist of fast winds whipping around low pressure cores," Newman wrote. The wind direction changed about 180 degrees, also indicative of the wind vortex passing overhead, peaking at 45 miles per hour, and caused the biggest air pressure drop yet recorded on the Martian surface. Dust devils are called aeolian processes in science-speak. Join us at patreon.com/universetoday. University of … And More…. 22:52 Could supermassive black holes be primordial black holes?

The High Resolution Imaging Science Experiment (HiRISE) camera, the most powerful camera ever sent to another planet, captured the epic photo back in October, its team at the University of Arizona said Monday. InSight as seen from space. Not only that, but we have rovers wandering around on the surface taking pictures of the dust storms, too. Get the latest science stories from CNET every week.

But unlike the rovers, InSight has sensors that, "It didn't make a significant difference to our power output, but this first event is fascinating science," said InSight science team member Ralph Lorenz of Johns Hopkins University's Applied Physics Laboratory.

This one was captured by NASA’s Mars Global Surveyor (MGS) orbiter. While they're strong enough to lift dust, and perhaps push around sand grains, that's about the full extent of their power. And they can be pretty terrifying — NASA captured a photo of a 12-mile-high dust devil back in 2012. The exact height cannot be determined, though, as it appears that the funnel extends off the top of the image field of view. "The absolute fastest wind we've directly measured so far from InSight was 63 miles per hour, so the vortex that lifted dust off our solar panels was among the strongest winds we've seen," said InSight participating scientist Aymeric Spiga of the Dynamic Meteorology Laboratory at Sorbonne University in Paris.

Heated less-dense air close to the ground rises, punching through the layer of cooler denser air above; rising plumes of hot air and falling plumes of cool air begin circulating vertically in convection cells. Be respectful, keep it civil and stay on topic.
Until then, we can sit safely back here on Earth and enjoy the views from NASA's emissaries to the Red Planet.

We live in a time when our spacecraft orbiting Mars at an altitude of about 300 km. This is one of the MarCO spacecraft that followed InSight to Mars, a suitcase-sized CubeSat that helped communicate the successful landing of InSight with NASA. "But this dust devil was so impressive that -- if you look closely! This is due to the thin atmosphere, and thus how little force the winds in such a vortex could actually exert. But the mission. -- you can just see it moving to the right, at the border between the darker and lighter slopes, even in the raw images," wrote atmospheric scientists Claire Newman, a Curiosity team member with Aeolis Research, in an update last week. "There are several HiRISE images of tracks left behind by dust devils, but it is rare to catch one in motion," HiRISE team member Sharon Wilson said in a press release.
Although they were small -- 0.7% on one side and 2.7% for the other -- the boosts suggested that the wind was actually lifting Martian dust from the panels. Like us on Facebook: https://www.facebook.com/universetoday
