When astronaut Scott Kelly was preparing to head to space for a year-long mission on the International Space Station in 2015, he immediately thought about his brother.“This was going to be unique for NASA,” Scott Kelly says in an interview from Space Center Houston. “The first U.S. crew member spending a year in space… maybe there was some value in taking advantage of the fact that…I had an identical twin brother.”His identical twin happens to be former astronaut Mark Kelly, who would be on earth during the same period of time. Scott saw potential to learn something.“I think as an astronaut we have an obligation to promote science, perform the science, to be engaged in science,” he says.The journal publication Science was very interested in the idea. All they needed now was a team of researchers for what would be known as the 850

Two California police officers who killed Stephon Clark, an unarmed black man who was fatally shot in his grandmother's backyard last year, will not face criminal charges, Sacramento County District Attorney Anne Marie Schubert said Saturday.Schubert described a young man going through a tumultuous time in his life, facing jail time after being accused of assaulting his girlfriend and mother of his children days earlier. She said toxicology reports showed Clark had Xanax and alcohol in his system and that he had researched ways to commit suicide before his encounter with the officers."Was a crime committed?" Schubert told reporters. "There is no question a human being died. ... The answer to that question is no and, as a result, there was no criminal liability."Schubert would not characterize what happened as a "suicide by cop" but said "many things were weighing heavily" on Clark's mind at the time of the shooting.Clark was unarmed when he was shot seven times, including three times in the back, according to an autopsy released by the Sacramento County Coroner's office. An independent autopsy found that Clark was shot eight times, with six of those wounds in his back, according a forensic pathologist retained by Clark's family.The case became a symbol of strained relations between the police and the community as well as racial tensions in the state capital.Jamilia Land, a friend of Clark's family and member of CA Families United for Justice, in a statement said no prosecutor's "ruling can change the most important fact -- Stephon should be alive.""Stephon was unarmed and in no way a threat. Instead, they shot 20 times and hit Stephon at least 8 times. Even then, they did not call for medical care even though he was bleeding profusely. Now the Sacramento District Attorney says it's unjust to charge these officers with Stephon's murder—where is Stephon's justice?"Authorities said the two Sacramento officers who shot Clark were responding to a report that a man had broken car windows and was hiding in a backyard. Police chased the man -- later identified as Clark -- who hopped a fence into his grandmother's property. He was shot in her backyard on the night of March 18, 2018.Schubert, who opened her news conference with an apology to the Clark family, said she met with his mother Saturday morning.The prosecutor went through a lengthy presentation involving body worn cameras, helicopter surveillance video and photos. Clark vandalized three cars, moved to a backyard and broke a sliding glass door to a room where an 89-year-old man was watching television, and then jumped to another yard.Directed to Clark's location by the sheriff's helicopter, the officers chased Clark to a backyard."Hey, show me your hands," the lead officer said. "Stop. Stop."Schubert said, "Both (officers) describe that Mr. Clark was sanding with his arms extended in a shooing stance. Both officers believed he was pointing a gun at them."One officer saw a spark that he thought was a muzzle flash from a gun, she said. The other thought the flash was light reflecting off a gun."Show me your hands," one officers said, breathing heavily. "Gun. Gun."Clark was about 30 feet away behind a picnic table when the officers opened fire, the prosecutor said.After the shooting, protests erupted for several days in Sacramento as tempers flared. Frustrated residents and Black Lives Matter activists urged accountability for the shooting. At one point, protesters blocked the entrance to the Golden 1 Center, where the Sacramento Kings play, forcing them to play a game against the Atlanta Hawks in a nearly empty arena.Police said the officers who fired at Clark believed he was pointing a gun at them. But investigators determined Clark was actually carrying a cell phone.Clark's family last month filed a wrongful death lawsuit against the officers involved and the city of Sacramento.The federal lawsuit alleges the young man was racially profiled, and the officers used excessive force in the shooting incident. The two officers failed to identify themselves or issue a verbal warning before firing approximately 20 shots, the suit said. The lawsuit also alleges the officers did not get him medical attention immediately after the shooting.Mayor Darrell Steinberg devoted much of his 2019 "State of the City" speech to the shooting and apologized to Clark's family and the community, CNN 4416

US Secretary of Education Betsy DeVos met with lawmakers on Tuesday, and defended the Trump Administration for proposing nearly million in cuts to Special Olympics. Devos was questioned on the subject by Rep. Mark Pocan, D-Wis., who took issue with DeVos not knowing the number of participants in Special Olympics. “It’s 272,000 kids,” Pocan said,“Let me just say that I think Special Olympics is an awesome organization, one that is well supported by the philanthropic sector as well,” DeVos said.According to 2017 figures from Special Olympics, the organization had nearly 0 million in annual revenue. The majority of its budget comes from donations from individuals and corporations, which totals million a year.DeVos defended the move as one to save the government money. “We had to make some difficult decisions," she said. A number of prominent celebrities decried DeVos' testimony later on Tuesday. "Terrible. We should support athletes with disabilities, not rip away their opportunities," Chelsea Clinton tweeted. "The benefits of Special Olympics, which I have seen first hand as volunteer are IMMEASURABLE," actress Marlee Matlin tweeted. "DeVos proposal to cut their funding will adversely affect thousands with developmental disabilities. Don't let this happen!"According to Special Olympics, its mission is "to provide year-round sports training and athletic competition in a variety of Olympic-type sports for children and adults with intellectual disabilities, giving them continuing opportunities to develop physical fitness, demonstrate courage, experience joy and participate in a sharing of gifts, skills and friendship with their families, other Special Olympics athletes and the community." 1735

Weeks shy of his 95th birthday, former President Jimmy Carter said Tuesday he doesn't believe he could have managed the most powerful office in the world at 80 years old.Carter, who earlier this year became the longest-lived chief executive in American history, didn't tie his comments to any of his fellow Democrats running for president, but two leading 2020 candidates, Joe Biden and Bernie Sanders, would turn 80 during their terms if elected.Biden is 76. Sanders is 78."I hope there's an age limit," Carter said with a laugh as he answered audience questions during his annual report at the Carter Center in Atlanta. "If I were just 80 years old, if I was 15 years younger, I don't believe I could undertake the duties I experienced when I was president."Carter's observation came in response to a jovial inquiry about whether he had considered running in 2020 since he's still constitutionally allowed another term. The 39th president left office in 1981 at the age of 56 after losing his reelection bid to Ronald Reagan, who served two terms and left office as the oldest sitting president in history, at 77.Carter, who turns 95 on Oct. 1, said the Oval Office requires a president "to be very flexible with your mind," particularly on foreign affairs.Carter also commented on the Israeli election, lamenting that returning hard-line Prime Minister Benjamin Netanyahu to power could "end the peace process" altogether. Exit polls show that Netanyahu's party fell short of securing a parliamentary majority, potentially threatening his position. 1563
