ATLANTA — The United States is going to require airline travelers from Britain to get a negative COVID-19 test first. The Centers for Disease Control and Prevention announced the new policy late Thursday. Airline passengers from the United Kingdom will have to test negative for COVID-19 within three days of their flight. The requirement goes into effect Monday.The U.S. is the latest country to announce travel restrictions because of a new variant of the coronavirus that is spreading in Britain and elsewhere. The new of the virus is more contagious than other strains.The CDC said because of restrictions in place since March, air travel to the U.S. from the U.K. is down by 90%. 692
ATLANTA (AP) — Marjorie Taylor Greene has won the Republican nomination for Georgia’s 14th Congressional District. She’s a businesswoman who has expressed support for the far-right conspiracy theory QAnon and been criticized for a series of racist comments. Neurosurgeon John Cowan was defeated in the primary runoff for the open seat on Tuesday. Greene's victory comes despite several GOP officials denouncing her campaign after videos surfaced in which she expresses racist, anti-Semitic and anti-Muslim views. She has responded to the criticism by blasting “the fake news media” and “the DC swamp.” Her victory comes in a deep-red area in northwest Georgia. 668

AURORA, Colo – A man is giving a family a piece of their hero back after finding World War II dog tags on a job site he was working on.“They’re going into the mail today,” Michael Huber said in his office, surrounding by old photos and knick-knacks packed away in a box.Huber has all the respect in the world for a man he’s never met, but came across his name in the dirt.“Well, I was excavating on my jobsite,” Huber said. “I was getting rid of some trash and debris from years ago, and I pulled out a bucket and there was something shiny sticking out. I saw what it was and it was dog tags.”The name Gail Sheldon was engraved on the tags.“It said he got his shot in 1943,” Huber said. “Amazing. World War II dog tags.”Doing a little research, Huber found out who Sheldon was.“He was a captain and flew B-24 bomber planes,” Huber said. “He had several missions over Berlin, and he flew during D-Day. He was even shot down one time.”Huber was able to get into contact with Sheldon’s family after a couple of months. He found out from the family Sheldon died in 1990.Huber is now sending back the dog tags along with Sheldon’s pilot wings that he found with the tags. He packs up a box filled with old coke bottles and old squirt guns from that time that he found on the job site.“It could possibly be his family’s,” Huber said.Huber, who has also served in the U.S. Army, said he deeply respects Sheldon. Which is why it's important to send this memento back to the family.“Dog tags to me is part of a person’s being,” Huber said. “It’s a symbol of them giving up everything.” 1584
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
At least three people in Louisiana have died as a result of Hurricane Laura after trees fell onto their homes.Gov. John Bel Edwards said he’s received a report of the first US fatality from Hurricane Laura in Louisiana, a 14-year-old girl who died when a tree fell on her home. 285
