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 federal judge in Seattle granted a motion for a preliminary injunction on Monday that blocks a Texas man from releasing downloadable blueprints for 3D-printed guns until the litigation is resolved, according to court documents obtained by CNN.Judge Robert S. Lasnik of the US District Court for Western Washington extended an earlier temporary restraining order, which will now remain in place until the case is resolved, the court documents state."The Court finds that the irreparable burdens on the private defendants' First Amendment rights are dwarfed by the irreparable harms the States are likely to suffer if the existing restrictions are withdrawn and that, overall, the public interest strongly supports maintaining the status quo through the pendency of this litigation," Lasnik wrote in the ruling.The ruling comes as part of a years-long battle between the federal government and Defense Distributed, an organization that in 2013 posted designs for a 3D-printed handgun called the Liberator. The pistol was made out of ABS plastic, the same material used in Lego blocks, and could be made on a 3D printer.The US government ordered him to take the blueprints down that year, and the company's founder Cody Wilson sued the government in 2015. The Trump administration settled the case in June, and the 3D weapon blueprints were scheduled to be posted online August 1.However, Washington state and other states sued to block the release of the blueprints that day. Judge Lasnik sided with the states and temporarily blocked the settlement, although more than 1,000 people downloaded the designs before the judge's decision.Defense Distributed took down the plans after the temporary restraining order, and a note on the website DEFCAD explained the reasoning."This site, after legally committing its files to the public domain through a license from the US Department of State, has been ordered shut down by a federal judge in the Western District of Washington," the website DEFCAD.com says. 2011

A federal judge ordered the Trump administration to fully restore the Deferred Action for Childhood Arrivals program Friday and accept new applicants for the first time since 2017, according to media reports.A judge with the U.S. District Court in Brooklyn told the Department of Homeland Security to post a public notice by Monday that states they will accept DACA petitions from immigrants who qualify and are not currently enrolled.The judge also instructed DHS officials to grant approved applicants work permits that last two years, and not the one year limit the Trump administration had proposed, according to CBS News."DHS is DIRECTED to post a public notice, within 3 calendar days of this Order, to be displayed prominently on its website and on the websites of all other relevant agencies, that it is accepting first-time requests for consideration of deferred action under DACA, renewal requests, and advance parole requests, based on the terms of the DACA program prior to September 5, 2017, and in accordance with this court's Memorandum & Order of November 14, 2020," the judge wrote.The Trump administration tried to end DACA in 2017, but the U.S. Supreme Court ruled against him in June 2020. Wolf issued a memo in July saying that new applications for DACA would not be accepted and renewals would be limited to one year. The memo essentially suspended the program.Friday’s order follows a ruling in November from the same judge that found acting DHS secretary Chad Wolf did not have the legal authority to close DACA to new applicants, shorten the period for work permits or change protections from deportations.The judge ruled at the time Wolf’s appointment to his position violated the Homeland Security Act of 2002. In his ruling, the judge wrote DHS failed to follow an order of succession established when then-Secretary Kirstjen Nielsen resigned in April 2019.The nonpartisan Government Accountability Office determined in August that Wolf’s appointment was invalid. 2003

  

A draft of the much-anticipated report from the Justice Department's internal watchdog, addressing a wide-ranging set of allegations that department protocols were flouted when the FBI investigated Hillary Clinton's handling of classified information, has been completed, according to sources with knowledge of the matter.Inspector General Michael Horowitz informed lawmakers on Capitol Hill Wednesday that his office has provided leadership at the Justice Department and FBI with a copy of the draft report and has requested that they review it for classified information."We will update you on the specific timing for the report's release, and I will be prepared to provide a briefing and testify publicly about our findings and conclusions as soon as the report is released," Horowitz wrote in a letter to members of various committees. 847
