Andrew Luck, a quarterback for the Indianapolis Colts, announced over the weekend that he was retiring from professional football at 29 years old, drawing reactions from just about every corner of the internet."This is not an easy decision," Luck said. "For the last four years or so I've been in this cycle of injury, pain, rehab, injury, pain, rehab. And it's been unceasing and unrelenting ... and the only way I see out is to no longer play football."Injuries had kept Luck from playing in the preseason. Luck said the pain has taken away his joy for the game and he hasn't been able to live the life he wants to live. He played the 2016 season in pain, he said, and made a vow he wouldn't go down that road again. According to 744

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

Bob and Shirley Hansen were on a fishing trip when they woke up at 3 a.m. Monday to the sound of someone beating on the side of their boat.Bob looked over the side and saw five people in their underwear, he told CNN affiliate KEYT-TV. Then he saw another boat in the distance, fully engulfed in flames."Flames probably 30 feet high. It was totally gone," he said. The first thing he did was call the Coast Guard, he said.The 75-foot commercial diving boat, called the Conception, caught fire Labor Day off the coast of Santa Cruz Island in Southern California.The Hansens were able to rescue the five crew members who made their way to their boat. Eight people have been found dead so far, and 26 are missing.Shirley said some of the rescued crew members told them about the moments on the boat before the fire. One said that a 17-year-old girl on the Conception was celebrating her birthday with her parents, she said."It was such a hopeless, helpless feeling to watch that boat burn and know there were only five people at our boat and there was nothing we could do," she said.She also said the five people didn't have any form of communication on them -- no keys or phones -- and she hopes they get plenty of help.Bob told KEYT he doesn't feel he deserves to be called a hero."I was just a guy there in that place. I would hope that anybody would do the same thing," Bob said, adding that he wishes he could have saved everyone on board the Conception. 1467

  

California Gov. Gavin Newsom passed SB 206, also known as the Fair Pay to Play Act, into law Monday. The law allows college athletes to profit from their name, image and likeness.The bill will go into effect in 2023, and if the bill survives the expected court challenges, it could reshape the NCAA's business model.The formal signing of the bill was done on LeBron James' show on HBO called "The Shop.""I'm so incredibly proud to share this moment with all of you," James wrote on Twitter. "@gavinnewsom came to The Shop to do something that will change the lives for countless athletes who deserve it! @uninterrupted hosted the formal signing for SB 206 allowing college athletes to responsibly get paid."The Fair Pay to Play Act allows college athletes in California to sign endorsement deals; earn compensation based on the usage of their name, image and likeness; and sign all types of licensing contracts that would allow them to earn money.These college athletes would also be able to hire an agent licensed by the state to represent them in any deals."Currently, student athletes are prohibited from being compensated even though their respective college or university makes millions from their athletic performance. That participation often comes at great risk to their health, academic success, and professional prospects," the Governor's office said in a statement."SB 206 makes California the first state in the nation to allow college athletes to receive compensation from the use of their name, image and likeness." 1541
