A Chinese lunar capsule returned to Earth on Thursday with the first fresh rock samples from the moon in more than 40 years, offering the possibility of new insights into the history of the solar system and marking a new landmark for China’s rapidly advancing space program.The capsule of the Chang’e 5 probe landed just before 2 a.m. (1800 GMT Wednesday) in the Siziwang district of the Inner Mongolia region, the China National Space Administration reported.The capsule had earlier separated from its orbiter module and performed a bounce off Earth’s atmosphere to reduce its speed before passing through and floating to the ground on parachutes. Following recovery, the capsule and its cargo of samples were flown to the space program’s campus in Beijing to begin the process of disassembly and analysis, the space administration said.The mission achieved new firsts for the lunar exploration program in collecting samples, launching a vehicle from the moon’s surface and docking it with the capsule to return the samples to Earth, the administration said.“As our nation’s mostly complex and technically groundbreaking space mission, Chang’e 5 has achieved multiple technical breakthroughs ... and represents a landmark achievement,” it said.Two of the Chang’e 5’s four modules set down on the moon on Dec. 1 and collected about 2 kilograms (4.4 pounds) of samples by scooping them from the surface and drilling 2 meters (about 6 feet) into the moon’s crust. The samples were deposited in a sealed container that was carried back to the return module by an ascent vehicle.Much to the amusement of viewers, footage run by state broadcaster CCTV showed a furry white animal, possibly a fox or rodent, running in front of the capsule as it lay on the ground, stopping briefly as if to inquire into the unfamiliar object.Chinese leader Xi Jinping, in a statement read out at the Beijing Aerospace Control Center, called it a major achievement that marked a great step forward for China’s space industry. Xi expressed hope that mission participants would continue to contribute toward building China into a major space power and national rejuvenation, state-run Xinhua News Agency said.Recovery crews had prepared helicopters and off-road vehicles to home in on signals emitted by the lunar spacecraft and locate it in the darkness shrouding the vast snow-covered region in China’s far north, long used as a landing site for China’s Shenzhou crewed spaceships.The spacecraft’s return marked the first time scientists have obtained fresh samples of lunar rocks since the former Soviet Union’s Luna 24 robot probe in 1976.The newly collected rocks are thought to be billions of years younger than those obtained earlier by the U.S. and former Soviet Union, offering new insights into the history of the moon and other bodies in the solar system. They come from a part of the moon known as the Oceanus Procellarum, or Ocean of Storms, near a site called the Mons Rumker that was believed to have been volcanic in ancient times.As with the 382 kilograms (842 pounds) of lunar samples brought back by U.S. astronauts from 1969 to 1972, they will be analyzed for age and composition and are expected to be shared with other countries.The age of the samples will help fill in a gap in knowledge about the history of the moon between roughly 1 billion and three billion years ago, Brad Jolliff, director of the McDonnell Center for the Space Sciences at Washington University in the U.S. city of St. Louis, wrote in an email. They may also yield clues as to the availability of economically useful resources on the moon such as concentrated hydrogen and oxygen, Jolliff said.“These samples will be a treasure trove!” Jolliff wrote. “My hat is off to our Chinese colleagues for pulling off a very difficult mission; the science that will flow from analysis of the returned samples will be a legacy that will last for many, many years, and hopefully will involve the international community of scientists.”Chang’e 5 blasted off from a launch base in China’s southern island province of Hainan on Nov. 24 and appeared to have completed its highly technically sophisticated mission without a hitch.It marked China’s third successful lunar landing but the only one to lift off again from the moon. Its predecessor, Chang’e 4, became the first probe to land on the moon’s little-explored far side and continues to send back data on conditions that could affect a future extended stay by humans on the moon.The moon has been a particular focus of the Chinese space program, which says it plans to land humans there and possibly construct a permanent base. No timeline or other details have been announced.China also has joined the effort to explore Mars. In July, it launched the Tianwen 1 probe, which was carrying a lander and a robot rover to search for water.In 2003, China became the third country to send an astronaut into orbit on its own after the Soviet Union and the United States and its space program has proceeded more cautiously than the U.S.-Soviet space race of the 1960s, which was marked by fatalities and launch failures. By taking incremental steps, China appears on the path toward building a program that can sustain steady progress.The latest flight includes collaboration with the European Space Agency, which is helping to monitor the mission. Amid concerns over the Chinese space program’s secrecy and close military connections, the U.S. forbids cooperation between NASA and the CNSA unless Congress gives its approval. That has prevented China from taking part in the International Space Station, something it has sought to compensate for with the launching of an experimental space station and plans to complete a permanent orbiting outpost within the next two years.___This report corrects the date of the Chang’e 5 mission’s launch. 5854

A former University of Airzona athlete was the first witness today in the trial of a coach accused of choking her.Baillie Gibson was a shot put and discus thrower at Arizona. She says former track coach Craig Carter choked her and threatened to slash her with a box cutter when she tried to end a two-year sexual relationship.In opening statements, prosecutor Jonathan Mosher read the jury a series of texts between Gibson and Carter where he became more and more threatening as she said she planned to leave Tucson after graduating.She went to his office in McKale Center, the university's basketball arena and training center. That's where Carter allegedly choked her and threatened to slash her with a box cutter.Cater confessed to a University of Arizona Police officer. Carter's attorney, Dan Cooper, read the jury many of the same texts but said they show Carter's attack was the result of a momentary loss of control and was not the sort of deliberate attack required for a conviction.Prosecutors expect a short trial.The rest of their witness list only includes two police officers and a friend of Baillie Gibson. 1144

A Kentucky infectious disease expert who advocated for social distancing and the use of masks in her state has died after a monthslong battle with COVID-19.According to WBKO-TV in Bowling Green, Kentucky, Dr. Rebecca Shadowen — an infectious disease specialist at The Medical Center in Bowling Green and a community leader amid the pandemic — died on Sept. 11 following a four-month fight with the virus.According to a statement from The Medical Center, Shawoden had worked at the center since 1989 and had been a "physician leader" across Kentucky for more than 30 years.In the early days of the pandemic, Shadowen pushed tirelessly for those in her community to isolate and adopt common-sense social distancing measures."(I)f you could save the life of another person without harming your own, would you?" Showden posted on Facebook on March 13. "Although we are (fiercely) individuals, we still live as community. Please take the Coronavirus (COVID-19) seriously. YOU may be healthy or may not feel this is threatening to you."Shadowen later served on Bowling Green-Warren County Coronavirus Working Group — an inter-agency organization that helped set policy and informed Kentuckians about the risks posed by COVID-19.According to the Louisville Courier-Journal, Shadowen contracted COVID-19 on May 13. David Shawoden, Rebecca's wife, said that both she and their daughter tested positive for the virus, while her son did not. Shadowen's daughter reportedly only suffered mild symptoms.However, Rebecca Shadowen faced a steep road to recovery. NBC News reports she was on and off a ventilator and spent months in the hospital. In a July Facebook post, Shawoden thanked her friends for continued prayers and kind words and asked others to wear a mask or face covering while in public."Although I am not home yet, I am in a very long recovery period and making slow progress here in Bowling Green," she wrote. "Which, by the way is the greatest place on the planet with the most wonderful people." 2007

A man released on parole from prison two weeks ago stole a police SUV near Dayton, Ohio, and crashed into a minivan filled with children, killing two 6-year-old girls, police said Tuesday.Ten others were injured, including five children and the suspect. One child remained in critical condition, police said.Dayton's police chief said that 32-year-old Raymond Walters was driving at nearly 100 mph (161 kph) in the stolen police cruiser through the city's downtown Monday night when he ran a red light and hit two vehicles.The family in the minivan had just stopped at a library and was leaving when Walters slammed into them, police said. Six of those inside the minivan were from the same family and the other child was a relative, police said.A coroner identified the two who died as Eleanor McBride, of Huber Heights, and Penelope Jasko, of Dayton. They were cousins, the family's priest told the Dayton Daily News.It all started when Walters stabbed his father and then took off in his father's pickup truck, said Police Chief Richard Biehl.Walters' father was driving him to a hospital to undergo a mental health evaluation and when he found out he attacked his father, Biehl said.Soon after driving off, Walters crashed in the neighboring suburb of Riverside and then he jumped into a Riverside police SUV that had responded to the crash, police said.The officer had not known about the stabbing and had no reason to suspect that Walters might try to flee, said Riverside Police Chief Frank Robinson. The officer had used a stun gun while trying to get Walters out of the cruiser, Robinson said.Dashcam video showed Walters driving backwards in the stolen cruiser and ramming into another Riverside cruiser before driving away.Police in Dayton were looking for Walters, but they were not chasing him when he crashed downtown, Biehl said.The impact split the stolen cruiser into several large pieces.Police will pursue murder charges against Walters, who was hospitalized in stable condition Tuesday, Beihl said. His father, who had wounds to the head, arms, face and chest, also was in stable condition.State prison records show Walters served about two years for robbery before he was paroled on Aug. 10. 2220

A judge in New York has temporarily blocked the publication of Mary Trump’s book about President Trump and his family. Judge Hal B. Greenwald in Poughkeepsie ordered Tuesday that no portion of the book can be distributed before he decides the validity of Robert Trump's claims. Mary Trump’s book, Too Much and Never Enough: How My Family Created the World’s Most Dangerous Man was to be published in July by Simon & Schuster. Mary is the president's niece.Just last week, a New York City judge rejected Robert Trump’s request to halt publication. The following day, Robert Trump, the president’s brother, filed a second injunction request in New York Supreme Court.Robert Trump claims Mary Trump signed a confidentiality agreement in a legal settlement two decades ago that bars her from publishing the book. Mary Trump's lawyer promised an immediate appeal. 870
