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 detailed look at COVID-19 deaths in U.S. kids and young adults released Tuesday shows they mirror patterns seen in older patients.The report examined 121 deaths of those younger than 21, as of the end of July. Like older adults, many of them had one or more medical condition — like lung problems, including asthma, obesity, heart problems or developmental conditions.Deaths were also more common among those in certain racial and ethnic groups, according to the report from the Centers for Disease Control and Prevention. The CDC found 54 were Hispanic, 35 were Black, and 17 were white, even though overall there are far more white Americans than Black and Hispanic.“It’s really pretty striking. It’s similar to what we see in adults,” and may reflect many things, including that many essential workers who have to go to work are Black and Hispanic parents, said Dr. Andrew Pavia, a pediatric infectious diseases expert at the University of Utah. He was not involved in the CDC study.The numbers of young deaths are small though. They represent about 0.08% of the total U.S. deaths reported to CDC at the time, though children and college-age adults make up 26% of the U.S. population.Fifteen of the deaths were tied to a rare condition called multisystem inflammatory syndrome, which can cause swelling and heart problems.The report also found nearly two-thirds of the deaths were in males, and that deaths increased with age. There were 71 deaths among those under 17, including a dozen infants. The remaining 50 deaths were ages 18 to 20.Scientists are still trying to understand why severe illnesses seem to become more common as children age. One theory is that young children have fewer sites on their airway surfaces that the coronavirus is able to attach to, Pavia said. Another is that children may be less prone to a dangerous overreaction by the immune system to the coronavirus, he added.Thus far this year, the COVID-19 toll in children is lower than the pediatric flu deaths reported to the CDC during a routine flu season, which has been about 130 in recent years. But comparing the two is difficult for a number of reasons, including that most schools weren’t open during the spring because of the pandemic.___The Associated Press Health and Science Department receives support from the Howard Hughes Medical Institute’s Department of Science Education.

A glacier in Italy is turning pink. The color is caused by algae growth — and scientists worry it will make the glacier melt faster, because darker colors absorb more radiation.Past studies report 50% of ice in the Alps' glaciers will be gone by 2050 because of climate change. pic.twitter.com/cgGwWQcG81— AJ+ (@ajplus) July 7, 2020 340

A Houston police officer was killed Tuesday and a second officer was injured on Tuesday morning in what Police Chief Ralph Acevedo called a "domestic violence-type situation."The officer killed was Officer Harold Preston, 65, a 41-year-old police veteran. Acevedo described Preston as a great cop "and a better person."According to Acevedo, officers were called to a home in the city's southwest side of the city by a woman who described herself as the estranged wife of the man who lived there. She said she was moving out and needed to collect her belongings, but her husband wouldn't let her in the house.When police approached the door, the suspect allegedly fired at the officers. Preston was shot multiple times in the head. A second officer, Officer Cortney Waller, was shot in the shoulder and is expected to survive.Several hours after police first arrived, the suspect emerged from the house and exchanged gunfire with police. The suspect, idnetified as Elmer Manzano, 51, was transported to the hospital and is expected to survive. Acevedo said Manzano will likely be charged with murder.Manzano's son was also injured in the incident and was transported to a local children's hospital with non-life-threatening injuries.KTRK-TV in Houston reports that Tuesday's shooting comes days after a Houston Fire Department Arson Investigator was shot and killed while doing surveillance in the northwest side of the city. 1432

A hiker fell to his death on Monday while ascending Yosemite National Park's famous Half Dome trail, the US National Park Service said.The hiker was on the trail's Half Dome cables, the park service said in a statement. He was hiking with another person during thunderstorm activity around 4:30 p.m. when he slipped and fell.The cables take hikers up the last 400 feet to the summit of Half Dome, which rises nearly 5,000 feet above California's Yosemite Valley.Park rangers were notified and went to the scene to assist the second hiker, the NPS said. The missing hiker's body was found around 1 p.m. Tuesday.His identity will be released after his family is notified.The death is the first on the Half Dome cables since 2010 and the first visitor fatality in 2018, the park service said. 797
