Grab your headphones and prepare to be blown away.NASA just announced it has heard the first-ever "sounds" of wind on Mars. But if you're expecting howling, swooshes and crackles, you're in for a surprise. These are vibrations, captured by NASA's InSight lander, which touched down on the Red Planet just last week. The craft will stay put until November 24, 2020, measuring quakes that happen anywhere on Mars.This week, the craft recorded something unexpected."InSight sensors captured a haunting low rumble caused by vibrations from the wind, estimated to be blowing between 10 to 25 mph (5 to 7 meters a second) on Dec. 1, from northwest to southeast," the agency said.An air pressure sensor and a seismometer recorded the noise through the vibrations in the air and vibrations around the aircraft "caused by the wind moving over the spacecraft's solar panels."This is the only time when vibrations from the lander will be recorded by the seismometer, since it will be moved by the craft's robotic armed and placed on the Martian surface, along with other instruments.The craft's landing comes as part of NASA's mission to explore the planet's deep interior.InSight lander's sensors are designed to detect quakes and air pressure through wind vibrations. The lander will measure whether tremors have the same effect as earthquakes. The Seismic Experiment for Interior Structure (SEIS), the seismometer, will use the vibrations to help scientists configure more about the planet's interior."Capturing this audio was an unplanned treat. But one of the things our mission is dedicated to is measuring motion on Mars, and naturally that includes motion caused by sound waves," Bruce Banerdt, the InSight principal investigator at NASA's Jet Propulsion Laboratory, said in a statement.To better hear this bass sound, it's better you bring out your headphones, or your subwoofer, as NASA suggested.You can hear the sounds here and listen to NASA's news telecon with a panel of scientists here.The-CNN-Wire 2011

Health departments around the U.S. that are using contact tracers to contain coronavirus outbreaks are scrambling to bolster their ranks amid a surge of cases and resistance to cooperation from those infected or exposed. With too few trained contact tracers to handle soaring caseloads, one hard-hit Arizona county is relying on National Guard members to pitch in. In Louisiana, people who have tested positive typically wait more than two days to respond to health officials — giving the disease crucial time to spread. Contact tracing tracks people who test positive and anyone they’ve come in contact with. It was challenging even when stay-at-home orders were in place, but it’s exponentially more difficult now. 724

HARPERS FERRY, W.V. – For more than 2,000 miles, the Appalachian Trail winds its way through more than a dozen states.It’s so-called “psychological midpoint” is the town of Harpers Ferry, West Virginia.“This community represents all the communities up and down the trail,” said Sandy Marra, who heads up the Appalachian Trail Conservancy.Ever since the pandemic began, she said there’s been a noticeable increase in people hiking the trail.“On any given weekday, even in the dead of summer, typically you wouldn't see anyone out on our trails,” Marra said. “And during the week now, you could see dozens and dozens of people just hiking.”That’s something other public lands across the country are seeing, too, in the time of COVID-19 and social distancing.Deborah Williams is with the Outdoor Industry Association, based in Colorado.“We did see a trend of more people exploring the outdoors in March and April and then that really did continue into May and June,” Williams said. “And what we initially saw is a little bit of escapism, in the first few weeks, actually continued.”That outdoor recreation can have a big impact on the economy.In West Virginia, for example, the outdoor industry is responsible for more than 91,000 direct jobs, 0 million in local and state tax revenue and billion in consumer spending.Across the country, it all adds up to 7 billion in consumer spending, supporting 7.6 million jobs.Williams said there’s the potential for that to grow even more in every state across America, in part, because of federal funding from the new “Great American Outdoors Act,” which was just passed by Congress and signed into law by the president.“It will fully fund the land and water conservation fund to the tune of 0 million,” Williams said. “So, this is our country's really flagship mechanism for funding conservation and maintenance of our public lands and waters.”Back at the Appalachian Trail, Sandy Marra hopes people now rediscovering the outdoors take care to protect it, as well.“Because of the pandemic and so many people wanting to get outside, the resource was being overwhelmed,” she said. “This is a great chance for us to reach a whole new audience of people. This is their park, right? So, they get to use it and enjoy it, but they also have a responsibility too.”It's a responsibility that can help future generations experience what’s great about the great outdoors. 2419

GREENWOOD, Ind. -- There's nothing like a cold ice cream cone on a hot day. On Wednesday, a large group of second grade students from Greenwood Schools got to take a field trip over to a local ice cream shop after reaching their reading goals.The students who earned 50 Accelerated Reading (AR) points got the sweet treat from Mrs. Curl's Ice Cream Shop. Fifty points is the equivalent of reading 100 books -- quite the accomplishment for these young readers. "This year we had more kids than ever before," said teacher Amber Ploutz in a Facebook post. "So you can imagine it was quite a sight, all of us walking down."As the group of students crossed the city streets, they walked past a group of construction workers. Ploutz said one of the workers out front heard that the students were being treated to ice cream for reaching their reading goals. Instead of just congratulating the students, he took it a step forward and really made their day."He paid for all 54 kids' ice cream cones," said Ploutz. "He didn't want any recognition and said he did it because he was proud of all the hard work they put into school and told them to keep up the great reading."In return, Mrs. Curl's Ice Cream Shop paid that man's good deed forward. The shop gave out free drinks and ice cream to all members of the road crew and also to the police officers helping direct traffic in the area.The worker didn't want any recognition for his random act of kindness, and only gave students his nickname, to remain anonymous. He said people call him, Bub."So thank you, Bub," said Ploutz. "Today was a day these kiddos and I will never forget."   1686
