ATLANTA —The former Atlanta police officer who shot and killed Rayshard Brooks on June 12 has been released from jail after posting bond, local TV stations WXIA and WGCL report.A judge on Tuesday set a bond of 0,000 for Garrett Rolfe, who faces charges including felony murder in the killing of the 27-year-old Black man.WXIA reports that Rolfe will now have to wear an ankle monitor, surrender his passport, adhere to a curfew, and he can’t possess a firearm.In a statement obtained by WXIA and WGCL, attorneys representing the Brooks family said they’re disappointed that Rolfe was granted bond, but they understand it’s just one step in a long quest for justice.Rolfe fatally shot Brooks in the back when Brooks fired a Taser in his direction while running away after a struggle on. Rolfe is white.Felony murder convictions are punishable by a minimum sentence of life in prison.The shooting happened against the backdrop of demonstrations nationwide over police brutality. 987

As the debate about mask mandates continues in some states, a new study reportedly shows social distancing is just as important to reduce the spread of COVID-19. The study looked at the effectiveness of face coverings when someone coughs repeatedly, coughing is one of the symptoms of COVID-19.The study was published in a June issue of “Physics of Fluid”, by AIP Publishing, and was conducted by Talib Dbouk and Dimitris Drikakis from the University of Nicosia in Cyprus.The researchers used computer modeling to show the range of saliva droplets when people cough. Previous work from this group showed saliva can travel about 18 feet when a person coughs and is not wearing a mask or covering their mouth.This new study built on that research to add in the variables of face coverings and repeated coughing. They used information available about filters used in surgical masks. 887

At 3 p.m. ET on Monday, November 26, a group of researchers will be really sweating. The NASA InSight spacecraft will try to land on Mars.After six months of flight, the lander component of the probe will detach itself from the cruise stage and head into the atmosphere. The lander component initially looks a fair bit like the re-entry capsule used in the 1960s and 1970s for the Apollo moon missions -- sort of conical, with a smooth and flat bottom. That bottom is a crucial heat shield that is designed to protect the probe as it passes through the thin Martian atmosphere.The landing is a devilishly difficult feat. The landing capsule has to batter its way through the atmosphere. It will fly through the Martian air at an initial speed of 12,300 mph, and it must hit the atmosphere at an angle of precisely 12 degrees. Any shallower, and the probe will bounce off into deep space. Any steeper, and the probe will burn itself up in a spectacular and fiery death. The probe will first touch the atmosphere six minutes and 45 seconds before landing. During this phase, it will experience acceleration 12 times that of the Earth's gravity. Were the probe a 150-pound human, during the flaming descent, it would weigh nearly a ton.About 3? minutes after the probe hits the atmosphere, a parachute will deploy, slowing down the probe even more. Fifteen seconds later, explosives will blow the heat shield off, exposing the actual InSight probe hidden inside. Ten seconds after the heat shield falls away, the probe will extend its legs, much like an airplane extends its wheels before touching down.The probe will fall for an additional two minutes attached to the parachute and protected by its conical shell. About 45 seconds before InSight lands, it will drop out of the shell and fall toward the surface. As soon as it leaves the shell, its landing rockets will ignite.The actual InSight probe looks a little bit like the Apollo moon lander, with three legs to support it and a boxy top. The rockets will slow it further and stop any remaining horizontal motion. Then, about 15 seconds before touchdown, the InSight probe will descend at a speed of 8 feet per second, before hopefully touching down gently on the Martian surface.The entire landing sequence will take about seven minutes to occur. A radio signal from Mars to Earth currently takes about eight minutes and seven seconds to get here. So the complete landing process will take place before we find out if it was successful. It will be done automatically, entirely by the probe itself. For the scientists and engineers who designed InSight, this is called "seven minutes of terror."And they are right to be worried. Mars is a graveyard of failed probes. There have been 44 attempts by various national space agencies to land on Mars. Eighteen have been successful. Twenty-three have not. Three have achieved orbit but failed at a landing.So, what does InSight hope to achieve? Well, as it happens, a lot. But it's different than the intrepid Curiosity probe, which NASA landed in 2012. InSight will not move around. Instead, it will stay put and tell us of the interior of Mars.One thing it will do is emit radio waves that we can monitor on Earth. By making careful measurements of how the frequency of the radio waves change, we will be able to measure the degree to which Mars wobbles as it rotates. That will tell us something about the core of the planet, specifically its makeup and information on the degree to which it is molten.InSight will also deploy a seismometer to listen for marsquakes (like earthquakes, but Martian-style) and for impacts of meteors on the planet. Information gleaned from the waves the seismometer detects will tell us more about the planet's interior.The third thing InSight will do is to dig below the planet's surface. Using a jackhammer, the probe will drill down 5 meters (16 feet) into the planet and, basically, it will take the planet's temperature.There are many reasons this is interesting. Taking the temperature at that depth will allow planetary scientists to determine how much heat is escaping from Mars. More broadly, this measurement will allow a clear determination of the temperature of the planet much closer to the core.This information will tell us a lot about how Mars formed, which, in turn, will add to the information of how rocky planets, including our own Earth, typically develop.And if you're more of an explorer kind of person and not so interested in Martian geology, it will also tell us how warm the planet is at modest depths, which will tell us if there is any chance of liquid water on the planet. Perhaps obviously, if the Martian subsurface is warm enough, any buried water will be in liquid form and not ice. Finding liquid water would be the key discovery that would make Martian exploration relatively easy. A relatively recent possible discovery of a buried Martian lake was promising, but the data was not conclusive. Knowing that the ground is warm would be very comforting to possible future explorers.Exploring the solar system is the first step toward exploring the stars. The InSight probe will give us --well -- insight into whether this is something that humanity will achieve in the foreseeable future.And maybe Elon Musk's bet on him getting to Mars will become true. 5329

As school districts across the country prepare to return to school, small businesses that rely on child visitors are closely watching."We're probably at about 15-20% of the business that we normally do. It has been a real gut-wrenching, heart-wrenching moment," said Susan Shaw, owner of The Art Barn in Georgia.When the pandemic hit in March, she thought her business would only be on a month hiatus. Shaw, who goes by Farmer Sue, quickly realized that wasn't the case."By the end of the month I realized we are not going to be back to normal. The schools, our entire spring was lost and 95% of our summer is lost and 100% of our fall is lost because no one is going to be coming out on field trips," said Shaw.The Art Barn provides art and agriculture entertainment for children throughout the year. Shaw hosts birthday parties, school field trips and even teaches at private schools in the afternoon. They, like Benton Family Farms in Kentucky, rely almost entirely on birthday parties, field trips and summer camps to keep their businesses running.Benton Family Farms says their camps ended up getting canceled."Nothing. Five weeks of camp, every weekend of birthday parties, all of our mobile trailers going out. Our mobile trailer was going out to day care centers, churches and libraries," said owner Mary Marcum.Marcum says every single scheduled event they had was canceled. Marcum has been running educational programs on the farm her parents owned for 72 years."For eight weeks now I thought, gosh what can we do? Because my husband does most of the books and he’s said, 'You're in trouble. You’ve got to do something.' And I had done goat yoga about three years ago, but I didn’t have the time," said Marcum.Marcum ended up turning to that one program she felt could hold up during the pandemic: goat yoga."Goat yoga! People were like, it's almost outdoors, it just has a cover over it. It was an open barn and they started coming!" said Marcum.The twice weekend sessions are helping Benton Family Farms pay for some of the feed for their animals. Marcum is now taking donations, holding auctions online and creating any limited outdoor programming she can to try and stay open. So far, only about 180 people are coming out to visit the farm a month. Compare that to their normal of 4,000 people a month. "You're talking about a parent and a child. At 4,000 that’s ,000. I can do all the little things I want but there’s a lot that’s just too much to make up," said Marcum."There were a lot of tears, more prayers and then more tears and then it was finally in mid-June I was able to grab my bootstraps and say, ‘No, you made this business from absolutely nothing, a crazy idea no one thought would work. Girl get your gumption and get going,'" said Shaw.The Art Barn is also trying to be creative with programming to bring people back to her farm during the pandemic. Shaw is creating educational videos of her programs that can be used as a virtual field trip for school districts across the country."There literally will be a field trip online and we’ve broken them into the five stations so the school can purchase, rent those videos and go online," said Shaw.Small businesses like The Art Barn and Benton Family Farms are desperately hoping that schools will allow field trips again soon. Right now, they aren't expecting any student visitors this fall but are hopeful that COVID-19 rates will at least be low enough for field trips to resume in the spring. 3489

As part of his push to get schools reopened in the fall, he is calling on Congress to approve 5 billion in funding to help with additional costs associated with the coronavirus pandemic.“This funding will support mitigation measures such as smaller class sizes, more teachers and teacher aides, repurposes spaces to practice social distancing, and crucially mask wearing,” Trump said.Trump is also taking a different tact to compelling schools to reopen. Previously, Trump threatened to pull federal funds from schools that did not reopen. Many of those funds are through the Title 1 program, which are directed toward poorer and disadvantaged schools.Rather than pulling federal funds from schools that opt for virtual learning, Trump said that the supplemental funds would go with the students. Under his proposal, students could use federal funds for other in-person learning options, or for homeschooling.“If schools do not reopen, the funding should go to parents to send their child to public/private, charter, religious or home school of their choice, the keyword being choice,” Trump said. “If the school is closed, the money should follow the student so the parents and families are in control of their own decisions. So, we would like the money to go to the parents of the student. This way they can make the decision that's best for them.”Trump said that the CDC would issue new guidance Thursday evening on how to safely reopen schools.While Senate Republicans seem poised to pass additional education funds as part of a broader stimulus plan, Democrats are not as enthusiastic.Speaker Nancy Pelosi told reporters on Thursday that the bill “so far falls very short of the challenge that we face in order to defeat the virus and to open our schools and to open our economy.”The bill also includes funding for coronavirus tests and a second round of stimulus checks. 1887
