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.

ALEXANDRIA, Va. -- Within a quiet lab, are scattered fragments of America’s storied past.“I never thought I'd be doing anything like this,” said Kenneth McNeill, an eight-year veteran of the U.S. Air Force.He also spent three years in the reserves and now is a part of the “Veterans Curation Program,” which provides training in archiving and archaeology.“I think one thing that happens a lot is that we just exist, and we don't think about things that happened in the past,” McNeill said.In the lab, though, the past is never out of reach.The artifacts come from the U.S. Army Corps of Engineers, who discovered the items at sites across the country during the excavation and construction of major projects, like dams and canals.“The Army Corps of Engineers had a need for people to do this curation work and the veterans have a need to find work and gain new skills and feel comfortable getting back into the workforce,” said Sarah Janesko, administrator of the Veterans Curation Program.The lab spaces are provided around the country by New South Associates, a company which specializes in archaeology and partnered with the Army Corps to train the veterans.“They feel like they're part of this larger mission to preserve our history and the cultural materials that come with it,” Janesko said.In just over 10 years, the Army Corps said the program has trained nearly 700 veterans, with 72% of them landing permanent jobs, some with the Smithsonian and National Park Service, while another 19% have gone on to further their studies in college.“It also gives us a sense of purpose, which is something I think veterans sometimes need when they separate from the military,” McNeill said. “We live in an area that has a lot of history to it. So, it's good that we are helping restore some of these things.”All of this happening, while they gain new skills, along with a deeper appreciation of the past. 1909

Airport security checkpoints can be among the worst things about air travel. Most of us would like to have the TSA Pre-Check so we can skip the long lines and the wait, but the cost to have it processed steers us away from this travel perk.If you have a trip coming up this year, there is some good news. There's a way to get a free TSA Pre-Check membership.Right now, there are at least 12 credit cards and 5 loyalty programs that will let you get a TSA Pre-Check membership for free.The credit cards include certain American Express cards, Bank of America premium rewards, Chase Sapphire and Expedia Voyager card from Citi.The loyalty programs include Marriott rewards, United Mileage Plus and Club Carlson. We found, while many of the credit cards cover the TSA Pre-Check fee outright, the loyalty programs pay for it with points.You also need to consider if there's an annual fee for the credit card and if the tradeoff is worth it.Of course anytime you sign up for a credit card and or loyalty program you'll want to read the fine print, but it could be worth your while to check out your options to save some cash, and some time, when you travel.  1199

All national forests in California will close Wednesday evening as the state sees “explosive growth of fires throughout” the state.The U.S. Forest Service closed eight national forests in Southern California Monday night, and the rapid growth Tuesday in windy weather conditions led to the decision to close the remaining ten forest areas.Nearly 2.3 million acres have burned already this year, setting a state record. Roughly two dozen wildfires are burning currently. “The number of large fires and extreme fire behavior we are seeing across the State is historic," said Regional Forester Randy Moore in a release. "These temporary closures are necessary to protect the public and our firefighters, and we will keep them in place until conditions improve and we are confident that National Forest visitors can recreate safely.”More than 140 people had to be rescued from the path of the Creek Fire this week, some were hikers and campers trapped without a way to escape the rapidly spreading flames. The Creek Fire is burning in part of the Sierra National Forest, which was closed to visitors on Monday.The Forest Service manages 18 National Forests in California, which take up almost 20 million acres. Those designated forests also supply 50 percent of the water in California. 1290

A woman is suing Waffle House after saying she was served bleach in a drink she got from a restaurant in Georgia.Atavian Moore sued the restaurant chain Oct. 27, claiming the incident has cost her ,000 in medical bills so far, according to Atlanta's WSB-TV.Moore claims that when she was eating at a Waffle House in Lithonia, Georgia in October 2015, she was given a drink that had bleach in it. She assumes the bleach got in her drink after the restaurant cleaned its drink dispenser.WSB reported that Moore's lawsuit claimed she suffered injuries to her esophagus, stomach and other internal body parts because of the potentially deadly cocktail.According to the National Capital Poison Center, swallowing small amounts of bleach can cause mouth irritation and vomiting but when someone swallows a large amount of the chemical it can cause more serious problems.Clint Davis is a reporter for the Scripps National Desk.
