After almost two years circling an ancient asteroid hundreds of millions of miles away, a NASA spacecraft this week will attempt to descend to the treacherous, boulder-packed surface and snatch a handful of rubble.The drama unfolds Tuesday as the U.S. takes its first crack at collecting asteroid samples for return to Earth, a feat accomplished so far only by Japan.Brimming with names inspired by Egyptian mythology, the Osiris-Rex mission is looking to bring back at least 2 ounces (60 grams) worth of asteroid Bennu, the biggest otherworldly haul from beyond the moon.The van-sized spacecraft is aiming for the relatively flat middle of a tennis court-sized crater named Nightingale — a spot comparable to a few parking places here on Earth. Boulders as big as buildings loom over the targeted touchdown zone.“So for some perspective, the next time you park your car in front of your house or in front of a coffee shop and walk inside, think about the challenge of navigating Osiris-Rex into one of these spots from 200 million miles away,” said NASA’s deputy project manager Mike Moreau.Once it drops out of its half-mile-high (0.75 kilometer-high) orbit around Bennu, the spacecraft will take a deliberate four hours to make it all the way down, to just above the surface.Then the action cranks up when Osiris-Rex’s 11-foot (3.4-meter) arm reaches out and touches Bennu. Contact should last five to 10 seconds, just long enough to shoot out pressurized nitrogen gas and suck up the churned dirt and gravel. Programmed in advance, the spacecraft will operate autonomously during the unprecedented touch-and-go maneuver. With an 18-minute lag in radio communication each way, ground controllers for spacecraft builder Lockheed Martin near Denver can’t intervene.If the first attempt doesn’t work, Osiris-Rex can try again. Any collected samples won’t reach Earth until 2023.While NASA has brought back comet dust and solar wind particles, it’s never attempted to sample one of the nearly 1 million known asteroids lurking in our solar system until now. Japan, meanwhile, expects to get samples from asteroid Ryugu in December — in the milligrams at most — 10 years after bringing back specks from asteroid Itokawa.Bennu is an asteroid picker’s paradise.The big, black, roundish, carbon-rich space rock — taller than New York’s Empire State Building — was around when our solar system was forming 4.5 billion years ago. Scientists consider it a time capsule full of pristine building blocks that could help explain how life formed on Earth and possibly elsewhere.“This is all about understanding our origins,” said the mission’s principal scientist, Dante Lauretta of the University of Arizona.There also are selfish reasons for getting to know Bennu better.The solar-orbiting asteroid, which swings by Earth every six years, could take aim at us late in the next century. NASA puts the odds of an impact at 1-in-2,700. The more scientists know about potentially menacing asteroids like Bennu, the safer Earth will be.When Osiris-Rex blasted off in 2016 on the more than 0 million mission, scientists envisioned sandy stretches at Bennu. So the spacecraft was designed to ingest small pebbles less than an inch (2 centimeters) across.Scientists were stunned to find massive rocks and chunky gravel all over the place when the spacecraft arrived in 2018. And pebbles were occasionally seen shooting off the asteroid, falling back and sometimes ricocheting off again in a cosmic game of ping-pong.With so much rough terrain, engineers scrambled to aim for a tighter spot than originally anticipated. Nightingale Crater, the prime target, appears to have the biggest abundance of fine grains, but boulders still abound, including one dubbed Mount Doom.Then COVID-19 struck.The team fell behind and bumped the second and final touch-and-go dress rehearsal for the spacecraft to August. That pushed the sample grab to October.“Returning a sample is hard,” said NASA’s science mission chief, Thomas Zurbuchen. “The COVID made it even harder.”Osiris-Rex has three bottles of nitrogen gas, which means it can touch down three times — no more.The spacecraft automatically will back away if it encounters unexpected hazards like big rocks that could cause it to tip over. And there’s a chance it will touch down safely, but fail to collect enough rubble.In either case, the spacecraft would return to orbit around Bennu and try again in January at another location.With the first try finally here, Lauretta is worried, nervous, excited “and confident we have done everything possible to ensure a safe sampling.”___The Associated Press Health and Science Department receives support from the Howard Hughes Medical Institute’s Department of Science Education.

Ahead of the election, many social media sites are tightening things up. Many platforms are trying to make sure what you're searching for, what you're seeing and what you're reading is factual.Pick a platform or a search engine and it's not hard to find what you're looking for.“Remember in 2016, no one took social media seriously on either side,” said Jason Mollica, a professor of communications at American University in Washington DC.He teaches digital and social media analytics and public relations. He analyzes just how we communicate. These days, a lot of our conversing is over the internet. As the election inches closer, Mollica and his students are watching and discussing what's happening on social media platforms.“It’s not that much different but the stakes are higher, not from the perspective of voting but as in what these socia lnetworks are trying to do or not do it the wake of what happened in 2016,” Mollica said.Take Facebook for instance. The social site has been under scrutiny and they know it. Mark Zuckerberg posted from his own account about what changes the site is making, including informational posts about voting and how and where to vote. Facebook will block new political ads in the final week before the election, and they say they'll be working with officials to remove misinformation about voting.There are also rules against COVID-19 threats surrounding voting.Twitter is also taking a stand. Mollica says you might see something trending but if there's a problematic post, the original content will likely be pulled.“We’re not gonna allow this content to continue is something is shared by Joe Biden or Donald Trump or any political party,” Mollica said. “They’re going to make sure it’s taken down because they want to mitigate the negative news or the false news that comes out from certain accounts.”Twitter says it has election teams focusing on integrity, and the company is launching initiatives to help users find original sources of information. You'll also be able to report misleading information.“This isn’t censorship,” Mollica said. “This is something where social networks are saying, ‘Look, we understand we’re a news cycle.’ At least from Twitter’s perspective, they share news. They want to be a place where people get news. They’re looking… from a standpoint of you wouldn’t see that on a television station necessarily, why should you see that on twitter?”And Google, the site many turn to to search for anything and everything, has modified its autocomplete policies, removing predictions that could be viewed as claims for or against a specific party. And that is no easy task.“Think of a search giant like google. They can’t pull content off the internet but they can definitely take key words from search results and say we’re not going to show those to people,” Mollica said.Donald McLaughlin, co-founder of the Denver Based CP-Cyper said, it’s not that internet content is missing. Google has just made information harder to find. McLaughlin says, however, it doesn't mean that you can't find it on other search platforms.“Use a different search engine,” McLaughlin said. “There is Bing, DuckDuckGo, a few others that are meant to be less persuasive, less filtered that will give you exactly what you search for versus what they want you to see or what they think you want.”“So, Google trying to mitigate it somehow is a great start but you think about it’s basically putting a small cork in a huge hole and it’s still leaking and you can’t really stop it,” Mollica said.Most experts would agree it’s unfortunate that it has come to this.“We’ve gotten to a place now where misinformation does spread like wildfire on social media. People will sensationalize to get likes to get people to follow them and really doing the research to vet whether something is true or not is very important,” Mollica said.He says that's true whether you're buying a car, or voting. And while the internet giants can only do so much, it’s a big step on the keyboard as we move toward the election. 4053

Agents with the Tennessee Bureau of Investigation (TBI) have recovered two nude photographs of a woman taken by Metro Nashville Police Sergeant Rob Forrest while he was being paid by taxpayers to protect Nashville Mayor Megan Barry.That detail is contained in a new search warrant filed Wednesday, seeking permission from a judge to search Barry's mobile phone.TBI agent Joshua Savely said in his affidavit that the face of the woman is not visible in the photographs recovered from Metro Police emails.Those photos appear to have been taken on Forrest's city-issued iPhone, then deleted, the affidavit says.Still, Savley wrote that a separate picture recovered from Forrest's phone shows Barry wearing clothing similar to items visible in one of the nude photos. Barry can also be seen carrying a purse similar to one that appears in another nude picture."Your affiant believes that probable cause exists to show that Rob Forrest used a department issued iPhone 6s Plus while on duty," Savley wrote."It will also show that on May 15, 2017, and on October 18, 2017, he used this phone to photograph a nude or partially nude female. It will also show that Rob Forrest's timecards report that he was working while these photographs were taken."Your affiant believes probable cause exists to show that Rob Forrest was indeed not working at the time [those photographs] were taken but was rather participating in the affair with Megan Barry at these time."Forrest submitted his retirement to the Metro Nashville Police Department on Jan. 31, the same say that Barry admitted that she and Forrest had had an affair.  Search Warrant Affidavits (PDF) Search Warrant Affidavits (Text) 1718

ALPINE, Calif. (KGTV) - The West Fire Benefit Dinner and Live Auction held Saturday night in Alpine raised at least ,000 for the families who lost everything.A final tally of all the money raised could take up to a week; all of it going to the Alpine Foundation. The Community Resource Team (CRT) will distribute the funds based on merit. "We're a case management agency for long-term recovery and that's getting people from the point that they're at now, to the end when they're in safe and sanitary conditions and what we hope to do is fill in any gaps," Case Manager with CRT Dawn Hubert said.More than 400 people attended the standing room only event.The phoenix emblazoned on the center of the program a fitting metaphor for the families who have been working through ashes over the past month and a half.Colin Campbell is living the transition, telling 10News he was far from the flames when the West Fire swept through, but his heart was at the family ranch."He said you've got about a minute to escape the fire," Campbell said a Sheriff's Deputy was the one knocking on his parents' door, helping them and his brother escape the imminent danger."My dad literally left without his phone his wallet, anything," he said.The next day, he came to see the damage. He said it was eerie, "absolutely devastating, but the oddity of it, where all the structures had once been, I could still see them."He envisioned all of the buildings he's known for years where ashes sat. In the backyard, melted string lights hung limp, a burned popcorn machine set at the edge of the grass, opposite a nearly drained pool.Across the patio, a picnic table was transformed into something out of an archeology dig, with two stacked sifting trays as the end of a pile of shattered pottery."Dozens and dozens of other volunteers came out to our property on August 4th, during a really hot day and gave us about 8 hours of their time," Campbell said while the funds will help, you can't put a price tag on hope."This caring community has conveyed that and given that hope, that's what was most important," he said knowing somehow it will get easier to come back and work toward a new beginning. 2204

Amazon's cashier-free grocery store of the future is coming to San Francisco and Chicago.The company is expanding its experimental Amazon Go store to the two US cities, but did not say when they would open. It has posted job listings for store managers in the cities on its own site, which were first noticed by the Seattle Times.Amazon confirmed its plans for the two cities in a statement to CNNMoney. Earlier reports from Curbed and the San Francisco Chronicle found clues that Amazon was eying retail space in the two cities.Currently there is only one Amazon Go store: a small space located in the base of one of its Seattle skyscrapers that opened to the public in January.The store uses a collection of cameras and sensors to constantly track customers and inventory as they move around. Shoppers need to open the Amazon Go app to enter, and any products they take from the store are automatically charged to their account when they leave.There are no cashiers but there are plenty of human employees restocking shelves, checking ID for wines, and working security.Amazon is already in the grocery business. In addition to its own selection of food available for purchase online and the Amazon Fresh grocery delivery service, Amazon owns Whole Foods. It bought the upscale chain in June 2017 for .7 billion.While the Amazon Go store in Seattle doesn't bear Whole Foods' branding, it does stock plenty of the store's signature 365 brand products.  1469
