Boeing safely landed its crew capsule in the New Mexico desert Sunday after an aborted flight to the International Space Station that could hold up the company’s effort to launch astronauts for NASA next year.The Starliner descended into the Army’s White Sands Missile Range in the frigid predawn darkness, ending a two-day demo that should have lasted more than a week. A trio of red, white and blue parachutes popped open and airbags also inflated around the spacecraft to ease the impact. “We pinpoint landed it,” NASA Administrator Jim Bridenstine said at a post-landing briefing. The successful return capped a rocky start to a mission that was supposed to include a docking with the space station. Managers will review all the data before deciding whether to do another test flight or go straight to flying astronauts, said NASA’s Steve Stich. After seeing this first test flight cut short and the space station docking canceled because of an improperly set clock on the capsule, Boeing employees were relieved to get the Starliner back.Recovery teams cheered as they watched the capsule drift down through the air and make a bull’s-eye landing. The touchdown was broadcast live on NASA TV; infrared cameras painted the descending capsule in a ghostly white. As the sun rose, close-up views showed the large white and black capsule upright — with hardly any scorch marks from re-entry — next to a U.S. flag waving from a recovery vehicle. The astronauts assigned to the first Starliner crew — two from NASA and one from Boeing — were part of the welcoming committee. “A beautiful soft landing,” said NASA astronaut Mike Fincke. “Can’t wait to try it out.” It was the first American-made capsule designed for astronauts to make a ground landing after returning from orbit. NASA’s early crew capsules — Mercury, Gemini and Apollo — all had splashdowns. SpaceX’s Dragon capsule, which made its orbital debut last winter with a test dummy, also aims for the ocean at mission’s end.Minutes after touchdown, top NASA and Boeing officials poured into Mission Control in Houston to congratulate the team. The newly returned Starliner also got a personalized name: Calypso, after Jacques Cousteau’s boat.The capsule’s first trip to space began with a smooth rocket ride from Cape Canaveral on Friday. But barely a half hour into the flight, it failed to fire its thrusters to give chase to the space station and ended up in the wrong orbit. The problem was with the Starliner’s internal clock: It did not sync up with the Atlas V rocket and was off by 11 hours, according to Boeing’s Jim Chilton. The capsule burned so much fuel trying to orient itself in orbit that there wasn’t enough left for a space station rendezvous. Flight controllers tried to correct the problem, but between the spacecraft’s position and a gap in communications, their signals did not get through. They later managed to reset the clock. Boeing is still trying to figure out how the timing error occurred. The mission lasted nearly 50 hours and included 33 orbits around the Earth, about 100 orbits fewer than planned. A test dummy named Rosie the Rocketeer — after Rosie the Riveter from World War II — rode in the commander’s seat. Also returning were holiday presents, clothes and food that should have been delivered to the space station crew.Even though not all goals were met including a station docking, “in my eyes, it was a huge success,” said Boeing flight director Richard Jones.There were no parachute problems this time. Last month, only two parachutes deployed during an atmospheric test because workers failed to connect a pin in the rigging.“We didn’t do everything we wanted to do, but we don’t see anything wrong with this spaceship right now,” despite the timing error, Chilton said. He apologized to the six space station residents for not delivering their Christmas presents. Boeing had been shooting for its first astronaut launch in the first half of 2020. This capsule is supposed to be recycled for the second flight with crew; each Starliner is built to fly in space 10 times.The capsule will return to Florida’s Kennedy Space Center in two weeks for inspections and refurbishments.“We’ve got a lot of learning in front of us,” Bridenstine said. “But we have enough information and data to where we can keep moving forward in a very positive way.Despite its own setbacks, SpaceX remains in the lead in NASA’s commercial crew program.SpaceX’s Dragon crew capsule successfully completed its first orbital demo last March. While the flight to the space station went well, the capsule exploded a month later on a test stand at Cape Canaveral. If a launch abort test goes well next month, SpaceX could start launching NASA astronauts by spring and end a nearly nine-year gap in flying people from Cape Canaveral.As its space shuttle program was winding down, NASA looked to private industry to take over cargo and crew deliveries to the space station. SpaceX kicked off supply runs in 2012. Two years later, NASA hired SpaceX and Boeing to ferry astronauts to the orbiting lab. SpaceX got .6 billion under NASA’s commercial crew program, while Boeing received more than billion.The goal was to launch NASA astronauts by 2017.Because of delays, NASA is looking to buy another two seats on Russian rockets in 2020 and 2021 to guarantee a continuing U.S. presence on the space station. Even when private companies are regularly carrying up astronauts for NASA, the space agency always will reserve a seat for a Russian in exchange for a free U.S. seat on a Soyuz.Over the years, these Soyuz rides have cost NASA up to million apiece, with the tab totaling in the billions.A recent audit by NASA’s inspector general found a Starliner seat will cost slightly more than that, with a Dragon seat going for just over half the price.___The Associated Press Health and Science Department receives 5902

As flames burn through Brazil's rainforest, its inhabitants are at risk of losing their homes. The fires pose a serious threat to the Amazon's delicate balance of ecosystems, putting pressure on already endangered species of animals.Expect a significant loss of wildlife, says Roberto Troya, Vice President for Latin America and the Caribbean at the World Wildlife Fund (WWF). The Amazon contains one in 10 known species on earth, including at least 40,000 plant species and more than 400 mammal, 300 reptile, 400 amphibian and 3,000 freshwater fish species, 571

Attorney General Bill Barr will not recuse himself from overseeing special counsel Robert Mueller's investigation into Russian interference in the 2016 election, the Justice Department announced Monday."Following General Barr's confirmation, senior career ethics officials advised that General Barr should not recuse himself from the Special Counsel's investigation. Consistent with that advice, General Barr has decided not to recuse," according to Justice Department spokesperson Kerri Kupec.Prior to his confirmation, Democrats had raised concerns about a 19-page memo Barr authored in June 2018 detailing why he believed President Donald Trump's firing of FBI Director James Comey should not constitute obstruction of justice. Barr vowed to consult with ethics officials but did not make any pledge to recuse himself from the Russia probe. 855

As nearly 450 Pier 1 locations are set to close in the coming year, the company announced it is filing for Chapter 11 bankruptcy. Of the 450 locations set to close, 400 of them have either recently closed or started liquidating stock. In addition to the store closings, the company will shutter two distribution centers. The moves come during a rough time for brick and mortar retailers, as malls and shopping centers throughout the United States become more barren. Pier 1 said it is also in the process of securing a buyer for the company over the next six weeks. “In recent months, we have taken significant steps forward in our business transformation and cost-reduction initiatives," CEO Robert Riesbeck said. "We have worked to establish an appropriately sized and profitable store footprint, operating structure and merchandise assortment that will enable Pier 1 to better serve our customers across store and online channels. "Today’s actions are intended to provide Pier 1 with additional time and financial flexibility as we now work to unlock additional value for our stakeholders through a sale of the Company. We are moving ahead in this process with the support of our lenders and are pleased with the initial interest as we engage in discussions with potential buyers.” 1296
