SpaceX launched 60 more mini internet satellites late Monday, this time testing a dark coating to appease stargazers.It’s a “first step” compromise between SpaceX and astronomers fearful of having dark skies spoiled by hundreds and, eventually, thousands of bright satellites circling overhead.The Falcon 9 rocket blasted into a cold, clear night sky, recycled by SpaceX for its fourth flight. As the first-stage booster flew to a vertical landing on an ocean platform, the Starlink satellites continued hurtling toward orbit to join 120 similar spacecraft launched last year. Flight controllers applauded, and the launch commentator described the booster’s fourth touchdown as “awesome.” An hour later, all 60 satellites were free of their upper stage and making their own way in orbit. “It’s a beautiful sight,” the commentator observed.His Starlink fleet now numbering 180, SpaceX founder and chief executive Elon Musk plans to ultimately launch thousands of these compact flat-panel satellites to provide global internet service. Each spacecraft is just 575 pounds (260 kilograms).After the first Starlink batch of 60 was launched in May and the second in November, astronomers complained how the bright satellite chain was hampering their observations. In response, SpaceX came up with a darkening treatment to lessen reflectivity. The coating is being tested on one of the newly launched satellites.Jeff Hall, director of the Lowell Observatory in Flagstaff, Arizona, said the Starlinks have been just an occasional problem — so far — but noted the risk to stargazing will grow as the constellation expands and other companies launch their own fleets. He heads the American Astronomical Society’s committee on light pollution, space debris, and radio interference, and is working with SpaceX on the issue. The matter is on the agenda, in fact, at the society’s conference in Hawaii this week.“Anything that darkens the satellites is a step in the right direction,” Hall said in an email Monday. He said it’s too soon to know whether the dark coating will work, “but it definitely is just a first step and not enough to mitigate the issues astronomy will experience with the Starlinks.”The Starlinks are initially placed in a relatively low orbit of 180 miles (290 kilometeters), easily visible as a long, strung-out cluster parading through the night sky. Over a few months, krypton-powered thrusters raise the satellites to a 340-mile (550-kilometer) orbit. The higher the orbit, the less visible the satellites are from the ground, according to SpaceX. Even so, SpaceX said it’s supplying astronomy groups with the satellite coordinates in advance, so they can avoid the bright flyover times.Already established in launching satellites for others and making space station deliveries for NASA, SpaceX is among several companies looking to provide high-speed, reliable internet service around the world, especially in places where it’s hard to get or too expensive. Others include Jeff Bezos’ Amazon and OneWeb. SpaceX may start service later this year in the northern U.S. and Canada, then expand to the world’s most populated areas after 24 launches. 3170

Puff. Puff. Cash.That is what some in the marijuana tourism industry are betting on. “We’ve grabbed a larger section of the mainstream, so now we’ve grabbed the canna-curious,” said CEO of Colorado Cannibs Tours Michael Eymer.Now that recreational marijuana Is legal in 10 states and the District of Columbia, businesses like Eymer’s are sprouting up like weeds.Eymer’s company takes customers on tours of dispensaries and grow houses in the Denver area.“Where we’re at with this whole thing, my company and models like this, I really, firmly feel, it’s simply just the tip of the iceberg in how big this industry can be. You know, I feel that this industry can be as as the public, or social consumption of alcohol.”But these businesses are operating in a bit of a gray area, and it’s not always a smooth ride. "There was a misunderstanding a little over a year ago with the city of Denver, where we had some of our guests and our guides, ticketed, by the city for what they considered to be public consumption,” said Eymer.While pot is legal to possess, sell and consume across the state of Colorado, you still can’t smoke it in public.That became an issue last year, when a Colorado cannabis tours bus got pulled over by Denver police."We do have rules though, where you can legally consume marijuana and where you legally cannot consume marijuana," said Eric Escudero, a spokesperson for the Denver Department of Excise and Licenses.That’s just one of the hurdles different states are facing with the legalization of medical pot.“When the first slate of licenses were granted, it did not include social consumption or delivery,” said Shanel Lindsay who founded Ardent Cannabis.Lindsay is trying to make sure they don’t have the same kind of hiccups in Massachusetts.“I think it’s really important for states, when they’re, when they’re making these laws to make sure there’s a clear pathway for social consumption and delivery, when they’re writing the law," said Lindsay.Massachusetts voted to legalize recreational pot in 2016.The first stores to sell it didn’t open until last year, and the state is still working on the rules for cannabis consumption businesses.“We’ve always had private or underground social consumption events and you definitely still see people running social consumption events in a private way. But really what people want is the ability to legitimately run public events.”Like in California.The popular music festival “Outside Lands” in San Francisco includes an entire area called “grasslands,” where people can buy and smoke weed in an open-air setting.“I came last year and we weren’t able to buy weed, so I was super happy I was able to get a pre-roll," said one concert-goer.Back in Colorado, Eymer worked on passing a state law that will allow for licensing of all kinds of marijuana businesses. He says giving users and sellers that stress free feeling is why he does what he does. 2932

Several years ago, Oliver came to the U.S. to escape genocide in Central Africa.“I’m from the southwestern part of Cameroon. Just almost the border with Nigeria,” Oliver said. “Number one reason why we’re coming here is for safety.”He says he didn’t have very many rights in his country of origin and he feared for his life.“If I didn’t come here, I don’t think I’d be alive. Either I’d be dead, or I’d be in jail.”So he came to the U.S. to seek asylum. He was held in an ICE detention facility during the immigration process. Eventually, Oliver won his asylum case, and he was released, but with no money or family to help him transition into U.S. society.“I didn’t even know what is Colorado,” Oliver said.He says a security guard told him about 760

Several people are dead after a gunman opened fire near a downtown Dayton, Ohio entertainment district early Sunday morning.A few hours later, a crowd gathered around the scene of the mass shooting, looking at the bullet holes left behind.Anthony Hickson heard the gun shots and describes what happened next.“Everybody started bomb rushing and you knew something bad was going on,” he said. “People running over top of each other, because you could really only get out of one doorway.”Holding back his tears, Dayton local Christian Stargell said this shooting has shaken this community to its core.“The past couple of months have been real tough for Dayton, and I think we’ve seen how we can come together and handle it,” he said.Coming together in this time of need.“I’m doing this because I love Dayton and I want to do what's best for Dayton,” said Nicole Cornett of BIllie Gold Bubble Tea. On Sunday afternoon, Cornett parked her food truck a few blocks away from the shooting, saying she’s donating all the money she’s making to victims impacted by this shooting.“Dayton does nothing but lift you up and support you, and they do that to every business here in town,” she said. “It’s just really upsetting because people now are going to be afraid and they’re going to be afraid to come out.”This community, however, did not hide in fear. Rather, it filled the streets where this shooting happened.Hundreds of people came out Sunday night showing support during a candle light vigil saying Dayton can remember those who lost their lives and eventually survive this tragedy. 1589
