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

Bomb squad officers have deemed two suspicious packages found Friday morning around a downtown New York subway station safe, the New York Police Department said."They are NOT explosive devices," the NYPD chief of counterterrorism's account tweeted.The items were pressure cookers, according to two law enforcement sources. They do not appear to be modified in any way, one of the sources said. Authorities are looking into whether the items were left behind.One package was found at Fulton and William streets, and the other was found on the nearby subway platform that serves the 2 and 3 trains, another law enforcement official said.Subway trains are bypassing the area for now.A New York Police Department emergency services unit also responded around 7:15 a.m. ET to the scene, the official said. Three New York Fire Department units were sent to the scene of the Fulton Street subway complex, as well, a department spokesperson said. 950

California Rep. Eric Swalwell is expected to announce Monday that he's dropping out of the 2020 race for president, according to a source familiar with his plans.Swalwell is expected to make the announcement at a 4 p.m. ET news conference at his campaign headquarters in California, concluding a short-lived bid for the Democratic nomination that failed to gain any traction.A spokesperson for Swalwell's campaign declined to comment.Swalwell announced his long shot presidential bid in April, pledging to mount a campaign that focused on the need for generational change in the Democratic Party and his commitment to confronting gun violence in the United States.Swalwell, though, failed to gain traction in a crowded Democratic field and only qualified for the first set of Democratic debates because of the Democratic National Committee's 1% poll standard, not because of grassroots support.Swalwell recently canceled a two-day trip to New Hampshire on July 3 and 4, in the first signal that his campaign might be coming to an end.The high point of his campaign was likely his direct and blunt challenge to former Vice President Joe Biden, the race's frontrunner, during the late June debates, where the California Democrat noted that he was six years old when "a presidential candidate came to the California Democratic convention and said it's time to pass the torch to a new generation of Americans.""That candidate was then-Sen. Joe Biden," Swalwell added as the crowd gasped. "He was right when he said that 32 years ago. He is still right today."Biden shot back: "I'm holding onto that torch. I want to make it clear."But that was not enough to sustain Swalwell's campaign, which struggled to gain attention in the Democratic field despite the candidate's availability to media.Swalwell, throughout his campaign, urged Democrats to "go big and be bold." He proposed a gun buyback program to get certain weapons off America streets and said he would fund a study on gun violence.Standing outside the National Rifle Association headquarters in Virginia in June, Swalwell said, "We're not just here to stand up to the NRA ... we're here to beat the NRA."But Swalwell's campaign, at times, was often defined by awkward moments, like when he looked to deliver a clever line at the June Iowa Democratic Party's Hall of Fame celebration."I will be bold without the bull," the congressman said to a quiet audience. 2427

  

BBC radio broadcaster Danny Baker has been fired after posting a racist tweet about the Duke and Duchess of Sussex's new baby.On Wednesday, the BBC Radio 5 Live presenter tweeted a black and white photo of a man and woman holding hands with a chimpanzee in a suit and a top hat, with the caption, "Royal baby leaves hospital."Amid widespread accusations of racism, Baker deleted the tweet and said he was sorry the "gag" had "whipped some up." He claimed the connotations had not occurred to him because his "mind (is) not diseased."In a second message, Baker said that the tweet was "supposed to be a joke about Royals vs circus animals in posh clothes but interpreted as about monkeys & race, so rightly deleted. Royal watching not my forte." On Thursday, the broadcaster said he made an "enormous mistake."A BBC spokesperson said: "This was a serious error of judgment and goes against the values we as a station aim to embody. Danny's a brilliant broadcaster but will no longer be presenting a weekly show with us."Baker responded defiantly to the decision, saying on Twitter that the calls for his dismissal were a "masterclass in pompous faux-gravity" and that the BBC "literally threw me under the bus."Prince Harry and Meghan's newborn son, 1265
