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.

According to PETA’s latest press release, cow’s milk is a symbol of white supremacy.In a statement, the animal rights group links the dairy industry’s treatment of the cows to the concept of white supremacy.“Aside from ‘lactose-tolerant’ white supremacists, cow’s milk really is the perfect drink of choice for all (even unwitting) supremacists, since the dairy industry inflicts extreme violence on other living beings,” the organization said in part.“PETA is trying to wake people up to the implications of choosing this white beverage and suggesting that they choose something else pronto,” the statement continues.The release further claims that the dairy industry has “control over your mind.” Read the full statement by clicking here. 748

After seven months of traveling through space, the NASA InSight mission has landed on Mars. A few minutes later, InSight sent the official "beep" to NASA to signal that it was alive and well, including a photo of the Martian surface where it landed.Mission Control at NASA's Jet Propulsion Laboratory exploded into celebratory applause and cheers after the touchdown was confirmed.InSight, or Interior Exploration using Seismic Investigations, Geodesy and Heat Transport, is going to explore a part of Mars that we know the least about: its deep interior. It launched May 5. InSight will spend two years investigating the interior where the building blocks below the planet's surface that recorded its history. 718

Actress Tamera Mowry-Housley was active on social media on Thursday looking for help locating her and husband's niece Alaina Housley who was presumably at the California bar where a gunman killed 12 before taking his own life. Late Thursday morning, the couple confirmed to NBC News that Alaina Housley was among the 12 killed. "Our hearts are broken. We just learned that our niece Alaina was one of the victims of last night’s shooting at Borderline bar in Thousand Oaks," the couple said in a joint statement to NBC. "Alaina was an incredible young woman with so much life ahead of her and we are devastated that her life was cut short in this manner. We thank everyone for your prayers and ask for privacy at this time."Mowry-Housley's social media thread hours after the late-night shooting shows the frantic nature of trying to gather information of loved ones after mass shootings. The shooting took place before midnight late Wednesday night, and Mowry-Housley's Instagram post came more than nine hours later. Mowry-Housley's sister Tia Mowry was also active on social media trying to gather information. "Alaina Housely we are praying," Tia Mowry wrote in Instagram Thursday morning. "We love u! If you know anything or any information please let us know. We love you! #borderline"Earlier on Thursday morning, Alaina Housley's roommate had posted a plea on Twitter trying to find information on her roommate. Mowry-Housley responded to her niece's roommate and went to Twitter looking for any information she could gather on her niece. Mowry-Housley's husband Adam Housley then went to a California hospital in search of their niece. The Los Angeles Times reported that he was turned away by guards at the hospital. “My gut is saying she’s inside the bar, dead. I’m hoping I’m wrong,” he told the LA Times. He added that his niece's Apple Watch and iPhone locators were tracked to the bar's dance floor. The Los Angeles Times reported that Alaina Housley was 18 years old and a freshman at Pepperdine University. Pepperdine confirmed that 16 of its students were at the bar at the time of the shooting, and there was one unaccounted for as of late Wednesday morning.  2335
