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.

ALPINE, Calif. (KGTV) - An Alpine family woke up to panicked horses and a disturbing sight near their house: the remnants of burned sky lantern."Noticed the horses were panicking and running back and forth in their pens," said Lucy Olivier.Along Japatul Valley Road, Olivier and her husband woke up Saturday morning to terrified horses, bathed in sweat. One of them had injured his leg. The source of the horses' fear was just feet away: the burned-out remnants of a sky lantern. Banned in California, the small hot air balloons use candles to spark their flight.In the one Olivier discovered, there were birthday candles sitting on popsicle sticks, attached to straws and a large garbage bag. It landed near dry brush not far from the main house, an ominous sight in an area prone to wildfires."We were infuriated. Thank God it didn't start a fire, but it could have," said Olivier.In San Carlos, another anxious, but grateful family reported discovering a similar device and some burn marks on their roof on New Year's Day. It's the second time they have discovered a sky lantern on their property since Thanksgiving.Some 30 states have now banned sky lanterns, the suspected cause of wildfires from Utah to Washington to South Carolina. In Germany, police believe the device caused a fire at a zoo on New Year's Eve that killed more than 30 animals. It is the type of tragedy Olivier fears could be one lantern flight away, somewhere in San Diego County."You never know where it's going to land or what kind of damage it could cause," said Olivier.Olivier says her injured horse should be okay.In Germany, a mother and her two daughters are being investigated for possible charges of negligent arson in the zoo fire. 1728
Actor Kelly Preston has died at age 57. John Travolta, Preston's husband of 28 years, confirmed late Sunday that his wife had died after a two-year battle with breast cancer. Preston enjoyed a lengthy career in film and television, appearing in “Jerry Maguire,” “Twins” and at times starring with her husband in films like “Battlefield Earth” and “Gotti.” The couple was married in 1991 in Paris after meeting on a film set, and had three children together. They experienced tragedy in 2009 when their son Jett died after a seizure in the Bahamas. 555
According to a study published by UCLA's Anderson School of Management, the COVID-19 pandemic has put the U.S. economy into a "depression" and projects that the country's GDP won't return to pre-pandemic levels until early 2023.The study was published by David Shulman of UCLA's Anderson Forecast — a research firm at the school that publishes a quarterly outlook on the U.S. economy."Make no mistake, the public health crisis of the pandemic morphed into a depression-like crisis in the economy," Schulman wrote. "To call this crisis a recession is a misnomer."The report says that despite a drastic response from both the Trump Administration and the Federal Resevre, it will take years for both employment levels and GDP to return to were it was before COVID-19 reached America."Simply put, despite the Paycheck Protection Program too many small businesses will fail and millions of jobs in restaurants and personal service firms will disappear in the short-run," the report reads. "We believe that even with the availability of a vaccine it will take time for consumers to return to normal. (It took more than two years after 9/11 for air travel to return to its prior peak.) With businesses taking on a huge amount of debt, repayment of that debt will take a priority over new capital spending. And do not forget that state and local budgets suffered a revenue collapse that even with federal assistance it will take years to recover from."The U.S. lost 22 million non-farming jobs in the early months of the pandemic, the report says. The report does offer at least one bright spot: the housing market. The report mentions that despite high unemployment rates, "consumer demand remains strong" and that markets will return to pre-pandemic levels fairly soon.Finally, the report projects that the pandemic will accelerate some trends that were already in motion, particularly the growth of online retail, telecommuting and rising tensions between the U.S. and China. 1980
