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.

After threatening to shut off city utilities to homes in Los Angeles violating coronavirus pandemic public health orders, the mayor has taken action twice so far. Both houses reportedly continued to hold large gatherings or parties despite rules limiting group sizes to limit the spread of the coronavirus.On Tuesday, Mayor Eric Garcetti authorized city employees to shut off service to a home after its owner and residents held multiple large parties. The home is in the Cahuenga Pass area, near Hollywood Hills.https://twitter.com/MayorOfLA/status/1300905954666360832Los Angeles police responded to the home on August 24 after reports of a large gathering, according to the LA Times, and officers posted warnings on the property. The house hosted another large gathering on Sunday. The mayor then authorized services shut off.On August 5, Mayor Garcetti said he would authorize crews to shut off city water and power to homes that violated city rules limiting gatherings during the coronavirus pandemic.The first home to have their utility service disconnected was on August 19 in the Hollywood Hills area. In a tweet, the mayor said the action was taken “to stop the large parties held there in flagrant violation of our public health orders.”https://twitter.com/MayorOfLA/status/1296203922911027200The rental home was reportedly being used by Tik Tok stars Bryce Hall and Blake Gray, who are now facing charges. When he announced the misdemeanor charges, City Attorney Mike Feuer said he is not aware of any COVID-19 cases at the time that have been linked to their parties.Police have left warning notices at another home after a large party this week, according to KTLA.Garcetti and city officials are warning people to be safe and stay distant over Labor Day weekend.“Gatherings — parties, cook-outs and the other activities we usually do with non-household members on holidays — can easily lead to increases in transmission, hospitalizations and deaths,” L.A. County Public Health Director Barbara Ferrer said in a statement. 2041
About 60 percent of restaurants that had to close during the pandemic are now permanently closed, according to review site Yelp.Across industries, Yelp reports that 132,580 businesses that were listed as “open” on March 1 are now marked “closed”, and roughly 55 percent of those closures are permanent. Those percentages translate to 72,842 businesses permanently closed as of July 10 that were open in March, and more than 15,700 of those are restaurants.Las Vegas is suffering from the highest rate of closed businesses, with 861 that are now permanently closed. Las Vegas has seen a huge decrease in tourism, and according to Yelp, this accounts for the spike in closures.The rate of permanent closures has increased since April as the coronavirus pandemic spreads and businesses of all kinds are forced to close or adjust how they interact with customers, sometimes resulting in fewer sales. Yelp reports that the number of total closures, though, has fluctuated as states reopen and close down again based on outbreaks.However, some businesses are seeing far fewer permanent closures. These include professional services like lawyers, accountants, web design and tutors or educators. Health services like physicians, mental health services, and health coaches are also seeing fewer permanent closures during the pandemic.“With nearly every state (and even county) taking a tailored approach to reopening local economies we expect these shifts in consumer interest and business closures to continue to move at an unpredictable pace,” the report stated.As businesses opened up in June, Yelp reports that people are searching for alcohol-related experiences, with an increase in searches for wineries (up 51 percent since May), cideries (up 39 percent) and breweries (up 24 percent). Searches for outdoors activities has also increased since May, like ziplining (up 44%) and ATV rentals (up 37%). 1906
After President Donald Trump blasted violence that has transpired at Black Lives Matter protests, claiming that Democrats are encouraging riots, Trump was asked to address a violent encounter involving a supporter of his last week.Kyle Rittenhouse, 17, was charged on Wednesday for the deaths of two demonstrators in Kenosha, Wisconsin, and for wounding a third protester. It has since been determined through social media that Rittenhouse is a supporter of Trump.During his Monday news conference, Trump said about the incident in Kenosha, "That was an interesting situation. He was trying to get away from them, I guess… and he fell & then they very violently attacked him.Trump added, “He probably would've been killed."Trump’s statement was in line with claims made by Rittenhouse’s attorney, who said that the shootings were in self-defense.Rittenhouse "has suddenly found himself at the center of a national firestorm and charged with murder after defending himself from a relentless, vicious and potentially deadly mob attack in Kenosha, Wisconsin,” attorney John Pierce of Pierce Bainbridge said in a statement last week.The exact circumstances that led to last week’s shooting are unclear, but several videos posted on social media have given investigators some insight.One of the videos appeared to show Rittenhouse scuffling with demonstrators before firing several shots. He is then seen walking away from the incident with the gun dangling from his chest while holding his hands up.While officers initially did not confront Rittenhouse at the scene late Tuesday, he was arrested the next day.Trump is scheduled to visit Kenosha on Tuesday, the site of ongoing unrest following the shooting of Jacob Blake. Blake was shot seven times in the back by Officer Rusten Sheskey. Per department policy, Sheskey is on paid administrative leave.Protesters supporting the Black Lives Matter movement have called on both Sheskey’s firing and arrest for the shooting.White House press secretary Kayleigh McEnany told reporters earlier on Monday that Trump will visit businesses damaged amid the unrest.Earlier in the day, McEnany said Trump is "not going to wade into that"in addressing the Rittenhouse incident. 2225
Amazon just raised its minimum wage to , but that's not enough for some progressive politicians.Sens. Elizabeth Warren and Bernie Sanders sent a letter to Amazon CEO Jeff Bezos on Tuesday scolding the company for allegedly distributing a 45-minute instructional video to managers at recently-acquired grocery chain Whole Foods on how to defuse union organizing."Workers' rights do not stop at the minimum wage, and raising the pay of your lowest-paid workers, while important, does not give you a free pass to engage in potentially illegal anti-union behavior," Massachusetts Democrat Warren and Vermont independent Sanders wrote.Amazon did not immediately return a request for comment.The letter comes as Warren prepares for an all-but-certain bid for the 2020 Democratic presidential nomination. She has ramped up travel to early-voting states and told a crowd at a Massachusetts town hall two weeks ago that after the midterms she will "take a hard look at running for president."Warren this week released the results of a DNA test intended to combat President Donald Trump labeling her "Pocahontas" over Warren being listed in 1980s and 1990s law school faculty handbooks as Native American.Her political team has also turned Senate Majority Leader Mitch McConnell's 2017 admonishment that Warren was warned against reading a letter from Coretta Scott King criticizing Jeff Sessions on the Senate floor, but "nevertheless, she persisted," into a slogan. It handed out printed "PERSIST" signs at Netroots Nation, a major progressive gathering, in New Orleans in August.The aggressive moves are intended to make Warren's intentions clear to progressives -- and demonstrate that she is capable of fighting powerful Republicans — as Democrats prepare for a wide-open presidential nominating contest that more than two dozen mayors, governors, senators and House members are considering entering.In announcing its minimum wage, Amazon said it had "listened to our critics." Most prominent among them was former Democratic presidential candidate Sanders, who introduced legislation aimed squarely at charging the Seattle e-commerce giant for any safety net benefits its employees used.The letter to Bezos refers to a video?originally reported by Gizmodo in early September that allegedly told team leaders how to recognize signs of unrest among workers, and provided arguments for why a union would not be in the interests of the company or its workforce."Our business model is built upon speed, innovation, and customer obsession—things that are generally not associated with unions," the video said, according to Gizmodo. "When we lose sight of those critical focus areas we jeopardize everyone's job security: yours, mine, and the associates'."The senators' letter raised concerns that, if genuine, the video would constitute violations of the National Labor Relations Act, the law that protects worker organizing. Specifically, suggestions that a facility might close down if employees organize and any attempt to spy on union activity could be grounds for a complaint to the National Labor Relations Board.No recent charges appear on the Board's website, and a call to the Board was not immediately returned.The senators requested the full video distributed by Amazon to Whole Foods managers, any other materials pertaining to organizing activities and a list of law firms and consultants the company may have retained to help tamp down labor unrest.The Wall Street Journal reported in September that a nascent union organizing campaign was underway at Whole Foods.Unions are relatively rare in the industry, representing only 5% of retail workers in 2017, according to the Bureau of Labor Statistics.Warren, long a critic of large banks and corporations, also sent a letter Tuesday taking hedge funds to task for their roles in the bankruptcy of Toys 'R' Us, which resulted in the loss of 33,000 jobs. 3980
