  吉林前列腺炎能治吗   

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

Canadian Prime Minister Justin Trudeau apologized Wednesday after a photo emerged of him wearing brownface during a school event in 2001."I shouldn't have done it. I should have known better, but I didn't," he told reporters on an airplane. "And I'm really sorry."It was a photo taken when he was a teacher in 2001, attending an end-of-the-year gala with an "Arabian Nights" theme, he said.The future prime minister attended the event with friends and colleagues dressed as a character from Aladdin, said Zita Astravas, speaking on behalf of Trudeau's party, the Liberal Party of Canada. He was wearing a turban.The existence of the photograph was first reported by Time.Trudeau, 47, was sworn in as prime minister in November 2015. Trudeau, son of Pierre Trudeau, is the first child of a Canadian prime minister to become prime minister himself. 858

  

Brother and sister Paul and Angelica Gallegos have spent a lot more time together this past school year. That’s because their school district, 27J outside Denver, became the first district in a major metropolitan area to switch to a four-day school week.And at first, it was a scary idea for mom Crystal.“I was a little freaked out,” Gallegos said.She had to convince her employer to let her work from home, since her kids would now be there every Monday. So far, she says the new school schedule hasn’t been that hard to get used to.“I like it, but that’s because I get to spend time with my kids,” she said.Every Monday they’ve come to a local state park where the kids volunteer.“We feed the animals we feed the birds,” said 12 year old Angelica. “On certain days we take kids on trail walks.”But asked if they prefer the new shorter weeks in class?“[I’d] go back to the old way,” says 9-year-old Paul. “I’d rather have school Mondays then stay an extra hour.”To make their weeks shorter, the four classroom days have to be longer. And then there’s homework.“This year, we did almost two hours of homework a night ,” said mom Crystal. “And then she plays softball, so that on top of practice, on top of—it was just a lot for her this year.”The Roberts family just down the block has mixed feelings. Kendra, 12, who uses the extra day to hangout with friends, grins from ear to ear when asked if she likes it.“Yea,” she says smiling.Mom Alecia Roberts sees pros and cons.“We have more family time on the weekends because then we can focus on other things during Mondays,” Roberts said. “But I still work on Mondays.”District superintendent Chris Fiedler says the biggest reason for the change was to attract more qualified teacher applicants. And so far, he says, its worked.“[For] elementary teaching positions a good pool [of applicants] would have been 40-50, and we were seeing pools of over 100,” Fiedler said.He says they’re also more experienced applicants. The district will soon head into their second year of a three-year trial, but it could be here to stay.“It’s really been a useful tool,” Fiedler said.The district has offered daycare for every Monday. 2183
