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 Caroline County, Maryland man was arrested after an investigation led to criminal charges of possession and distribution of child pornography.The suspect, Jeffrey Litteral, 52, of Denton, Maryland, has been charged with possession of child pornography, distribution of child pornography, possession of obscene material and distribution of obscene material. Litteral was arrested near his home at around 7:30 p.m. Tuesday night and, from there, he was taken before a court commissioner for an initial appearance and was held without bond.This investigation began in 2017 when a Maryland State Police Criminal Enforcement Division investigator received information about possible child pornography being uploaded to the internet. This led to Litteral and the development of evidence that enabled investigators to obtain an arrest warrant.During the investigation, detectives also learned that Litteral was employed by the United States Secret Service. Officials there assisted during his investigation and arrest.The investigation is continuing, so additional charges are possible. 1114

  

A federal judge halted construction of the controversial Keystone XL oil pipeline on Thursday, in a blow to the Trump administration and a win for environmental groups.US District Judge Brian Morris found that the US government's use of a 2014 environmental review to justify issuing a presidential permit for construction of the cross-border pipeline violated the National Environmental Policy Act, the Endangered Species Act and the Administrative Procedure Act, according to the court order issued Thursday."The Court enjoins Federal Defendants and TransCanada from engaging in any activity in furtherance of the construction or operation of Keystone and associated facilities," the court document reads, "until the Department has completed a supplement to the 2014 SEIS (Supplemental Environmental Impact Statement) that complies with the requirements of NEPA and the APA."Environmental groups involved in bringing the 2017 lawsuit celebrated the decision."Keystone XL would be a disaster for the climate and for the people and wildlife of this country," said Jackie Prange, senior attorney at the Natural Resources Defense Council, one of the plaintiffs. "As the court has made clear yet again, the Trump administration's flawed and dangerous proposal should be shelved forever."In March 2017, President Donald Trump's administration issued a permit approving construction of the pipeline, reversing the Obama administration's decision to block the controversial project.The White House has not responded to CNN's request for comment on the judge's order.The permit approval followed years of intense debate over the pipeline amid steadfast opposition from environmental groups.They argued that the pipeline would support the extraction of crude oil from oil sands, a process that pumps more greenhouse gases into the atmosphere than standard crude oil extraction. They also opposed the pipeline because it would run across one of the world's largest underground deposits of fresh water.Native American groups argued the pipeline would cut across their sovereign lands.The-CNN-Wire 2099
