CAPE CANAVERAL, Fla. (AP) — Mars is about to get its first U.S. visitor in years: a three-legged, one-armed geologist to dig deep and listen for quakes.NASA's InSight makes its grand entrance through the rose-tinted Martian skies on Monday, after a six-month, 300 million-mile (480 million-kilometer) journey. It will be the first American spacecraft to land since the Curiosity rover in 2012 and the first dedicated to exploring underground.NASA is going with a tried-and-true method to get this mechanical miner to the surface of the red planet. Engine firings will slow its final descent and the spacecraft will plop down on its rigid legs, mimicking the landings of earlier successful missions.That's where old school ends on this billion U.S.-European effort .Once flight controllers in California determine the coast is clear at the landing site — fairly flat and rock free — InSight's 6-foot (1.8-meter) arm will remove the two main science experiments from the lander's deck and place them directly on the Martian surface.No spacecraft has attempted anything like that before.The firsts don't stop there.One experiment will attempt to penetrate 16 feet (5 meters) into Mars, using a self-hammering nail with heat sensors to gauge the planet's internal temperature. That would shatter the out-of-this-world depth record of 8 feet (2 ? meters) drilled by the Apollo moonwalkers nearly a half-century ago for lunar heat measurements.The astronauts also left behind instruments to measure moonquakes. InSight carries the first seismometers to monitor for marsquakes — if they exist. Yet another experiment will calculate Mars' wobble, providing clues about the planet's core.It won't be looking for signs of life, past or present. No life detectors are on board.The spacecraft is like a self-sufficient robot, said lead scientist Bruce Banerdt of NASA's Jet Propulsion Laboratory."It's got its own brain. It's got an arm that can manipulate things around. It can listen with its seismometer. It can feel things with the pressure sensors and the temperature sensors. It pulls its own power out of the sun," he said.By scoping out the insides of Mars, scientists could learn how our neighbor — and other rocky worlds, including the Earth and moon — formed and transformed over billions of years. Mars is much less geologically active than Earth, and so its interior is closer to being in its original state — a tantalizing time capsule.InSight stands to "revolutionize the way we think about the inside of the planet," said NASA's science mission chief, Thomas Zurbuchen.But first, the 800-pound (360-kilogram) vehicle needs to get safely to the Martian surface. This time, there won't be a ball bouncing down with the spacecraft tucked inside, like there were for the Spirit and Opportunity rovers in 2004. And there won't be a sky crane to lower the lander like there was for the six-wheeled Curiosity during its dramatic "seven minutes of terror.""That was crazy," acknowledged InSight's project manager, Tom Hoffman. But he noted, "Any time you're trying to land on Mars, it's crazy, frankly. I don't think there's a sane way to do it."No matter how it's done, getting to Mars and landing there is hard — and unforgiving.Earth's success rate at Mars is a mere 40 percent. That includes planetary flybys dating back to the early 1960s, as well as orbiters and landers.While it's had its share of flops, the U.S. has by far the best track record. No one else has managed to land and operate a spacecraft on Mars. Two years ago, a European lander came in so fast, its descent system askew, that it carved out a crater on impact.This time, NASA is borrowing a page from the 1976 twin Vikings and the 2008 Phoenix, which also were stationary and three-legged."But you never know what Mars is going to do," Hoffman said. "Just because we've done it before doesn't mean we're not nervous and excited about doing it again."Wind gusts could send the spacecraft into a dangerous tumble during descent, or the parachute could get tangled. A dust storm like the one that enveloped Mars this past summer could hamper InSight's ability to generate solar power. A leg could buckle. The arm could jam.The tensest time for flight controllers in Pasadena, California: the six minutes from the time the spacecraft hits Mars' atmosphere and touchdown. They'll have jars of peanuts on hand — a good-luck tradition dating back to 1964's successful Ranger 7 moon mission.InSight will enter Mars' atmosphere at a supersonic 12,300 mph (19,800 kph), relying on its white nylon parachute and a series of engine firings to slow down enough for a soft upright landing on Mars' Elysium Planitia, a sizable equatorial plain.Hoffman hopes it's "like a Walmart parking lot in Kansas."The flatter the better so the lander doesn't tip over, ending the mission, and so the robotic arm can set the science instruments down.InSight — short for Interior Exploration using Seismic Investigations, Geodesy and Heat Transport — will rest close to the ground, its top deck barely a yard, or meter, above the surface. Once its twin circular solar panels open, the lander will occupy the space of a large car.If NASA gets lucky, a pair of briefcase-size satellites trailing InSight since their joint May liftoff could provide near-live updates during the lander's descent. There's an eight-minute lag in communications between Earth and Mars.The experimental CubeSats, dubbed WALL-E and EVE from the 2008 animated movie, will zoom past Mars and remain in perpetual orbit around the sun, their technology demonstration complete.If WALL-E and EVE are mute, landing news will come from NASA orbiters at Mars, just not as quickly.The first pictures of the landing site should start flowing shortly after touchdown. It will be at least 10 weeks before the science instruments are deployed. Add another several weeks for the heat probe to bury into Mars.The mission is designed to last one full Martian year, the equivalent of two Earth years.With landing day so close to Thanksgiving, many of the flight controllers will be eating turkey at their desks on the holiday.Hoffman expects his team will wait until Monday to give full and proper thanks.___The Associated Press Health & Science Department receives support from the Howard Hughes Medical Institute's Department of Science Education.

CHICAGO, Ill. – McDonald’s says it’s giving away 10,000 free McRibs to fans who show off their clean-shaven face or smooth skin.To claim a free sandwich, McDonald’s says you must post a photo of your cleanly-shaven or baby-smooth face on your public Twitter or Instagram profile, using #Shave4McRibSweepstakes and tag @mcdonalds. Stories do not count.The first 10,000 entries will receive a code for a free McRib, available via McDelivery with Uber Eats, while supplies last. The chain says anyone can participate, “from your brother to your mother, sister-in-law or cousin’s roommate.”McDonald’s says the promotion began Monday and it’s in honor of the return of the McRib on Wednesday, as well as the end of No-Shave November, a month-long challenge where participants are asked to put down their razors and “get hairy" in the name of cancer awareness.No-Shave November is also a nonprofit devoted to fundraising for cancer research, prevention and education. McDonalds is collaborating with the organization and will make a donation to the charity’s cancer initiatives using the profits from McRibs on Wednesday.“Our bearded fans know… facial hair and the McRib just don’t mix—believe me, I’ve tried,” said Vice President of U.S. Communications, David Tovar. “With the nationwide return of the McRib, we’re helping fans enjoy every delectable moment by encouraging them to shave for a chance to win a free McRib. And we’re excited this year to partner with No-Shave November, a charity that knows a thing or two about facial hair.”“We’re thrilled McDonald’s is supporting this important cause, getting both the bearded and the non-bearded involved beyond November simply by purchasing a McRib,” said Senior Executive Director of No-Shave November, Monica Hill. 1771

Charlottesville, Virginia, is again bracing for journalists and protesters to converge on the city as jury selection begins Monday for the man accused of killing Heather Heyer at last year's Unite the Right rally.James Fields of Maumee, Ohio, is accused of plowing his Dodge Challenger into a crowd of counterprotesters during the August 2017 white nationalist gathering, killing Heyer and injuring several other people, police say.Heyer, 32, was a local paralegal and had attended the rally to speak out against white supremacy and racism. Her friends and families say she died for her beliefs.Fields stands charged with first-degree murder in Heyer's death. He also faces five counts of malicious wounding, three counts of aggravated malicious wounding and one count of failing to stop at an accident involving a death.Separately, he is charged with hate crimes in a 30-count federal indictment. Prosecutors in that case allege Fields espoused white supremacist ideals and denounced minorities on social media before traveling to Virginia for the rally. Once there, the indictment says, he drove his car into a crowd with the intention of hurting people he targeted based on his bigoted views.The 21-year-old has pleaded not guilty to the federal charges. It's unclear whether he has entered a plea to the state charges, though a trial would not likely be necessary if he had pleaded guilty.His attorney, Denise Lunsford, did not return an email seeking comment. Fields is being held without bail in the Albemarle/Charlottesville Regional Jail. 1564

  

CARLSBAD, Calif. (KGTV) - Tuesday night a teen was seen on camera stealing a decoration right off a home's walkway.The Klus family moved to Bressi Ranch three months ago, from Boston, and were thrilled to become part of the neighborhood tradition."I'm totally blown away I had no idea it was this extensive and this creative and it's incredible the scenes of it come up with the kids are loving it," Visitor Amanda Alcorn said."When we moved here the kids were super excited super pumped to be included in the decorating," Nora Klus said. She has a daughter in 5th grade and a son in 2nd grade.They transformed their entry into Skele-topia, a night at the movies.Wednesday morning she noticed something was wrong. She looked at the footage on her Ring Neighbors App from the night before, "I saw a few, it looked like teenagers, and then the last one in the group just snatched our little decoration.""My son was crushed, he was like why would anyone do that?" She said.The same question posed in other neighborhoods where similar thefts, like a beloved cat decoration in Carmel Mountain, and pumpkin smashing happened all over the county.Klus flipped her theft into a teachable moment, "We talked about stealing and, you know, what they would do if they were with friends who want to steal something.""You just hate that someone would sort of diminished from that, take away from all the time and money put into it," Alcorn said.Both Alcorn and Klus hoping the thief has a change of heart. "I hope that we can kinda just move forward and maybe that little person who took that will return it to us," Klus said.Klus put up a sign right next to where the decoration was replaced, reading, "Smile, you're on camera" hoping to deter potential thieves. 1801

  

CAMPO, Calif. (KGTV) — Border Patrol agents this week discovered several packages of narcotics stuffed inside a vehicle's gas tank at an East County checkpoint.The agents stopped the vehicle at a Campo border checkpoint at about 1:30 p.m. on Thursday. During initial questioning, a K-9 officer inspecting the vehicle alerted agents to a possible narcotics.As the K-9 officer further inspected the vehicle, the canine directed agents toward the vehicle's gas tank. Agents say they discovered 53 cellophane packages floating in the gas tank, containing about 58.6 pounds of methamphetamine worth 4,780.The driver, a 47-year-old U.S. citizen, was arrested and the narcotics were turned over to Drug Enforcement Administration.
