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

TAOS COUNTY, N.M. — Texas country music artist Kylie Rae Harris, 30, died in a car crash on Wednesday night. According to 134

Prosecutors who dropped felony charges against actor Jussie Smollett over his report of a hate crime attack "have fundamentally misled the public on the law and circumstances surrounding the dismissal," an Illinois lawyers group said.The way Cook County State's Attorney Kim Foxx and her office resolved the case also was "abnormal and unfamiliar to those who practice law," wrote the Illinois Prosecutors Bar Association.The scathing statement, issued Thursday, follows claims by Foxx and her top deputy, Joe Magats, that "alternative prosecution," like the resolution brokered in Smollett's case, is not uncommon and is available to all defendants, celebrity or not. Smollet, 36, agreed to forfeit ,000 bail and complete community service in exchange for the dismissal of 16 charges alleging he'd orchestrated a fake racist, anti-gay attack on himself.Further, Foxx and her office "falsely informed the public" that sealing the criminal case was "mandatory," the prosecutors' organization said. And a special prosecutor should have been appointed when Foxx, citing familiarity with a potential witness, recused herself from the case, the group insisted.Meantime, Chicago's corporation counsel on Thursday asked Smollett to pay 0,106.15 to cover the cost of the investigation into his claims of an attack.Calls for an investigation growSmollett, who is black and gay, told police two men attacked him on January 29, yelling racist and homophobic slurs while striking him, police said. Smollett said the incident ended with a noose placed around his neck and bleach poured on him, police said.Chicago police investigated the case as a possible hate crime, then later said they believed the attack was staged by Smollett to bolster his profile and career. A grand jury indicted Smollett in March on 16 counts of disorderly conduct.Following the charges' sudden dismissal this week, officials from the statehouse to the White House have demanded investigations and additional consequences for Smollett.A state lawmaker said he'll introduce legislation to 2071

Several soon-to-be-married Valley couples say they're worried they've lost the thousands of dollars they invested on their wedding venue.NOAH's Event Center in Chandler, Arizona, sent an email to couples who booked the venue off Cooper and the Loop 202 saying they were canceling their highly anticipated events. “I had to re-read it again honestly. I was like, 'What? Is this real?'" said Melanie Stephenson, whose wedding was set for March of 2020. “I just mailed out my invites in November, so I had to re-message everyone like, 'Sorry wedding is postponed until I don’t even know when.'"Stephenson says she paid off the cost of the venue last December forking over ,000 to rent the entire building for the night and for NOAH to provide bartenders for her big day.“It just really sucks," she added. "This is like a hit in the face pretty much for all of us." Stephenson says NOAH's story doesn't add up. “I made sure to choose a company that I thought was solid because they have 30 other buildings throughout the United States," she said. Court records show NOAH 1082
