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

Radioactivity was detected on the oven, vacuum filter and bone crusher of an Arizona crematory where a deceased man who'd received radiation therapy was incinerated, according to a new case report. Worse still, a radioactive compound unrelated to the dead man was detected in the urine of an employee there."It is plausible that the crematory operator was exposed while cremating other human remains," Dr. Nathan Yu of the Department of Radiation Oncology at the Mayo Clinic in Phoenix and his co-authors wrote in the 529

Senate Majority Leader Mitch McConnell on Wednesday introduced a short-term spending bill to fund the government through February 8, 2019 in an effort to avert a partial government shutdown this week.In remarks on the Senate floor, McConnell said that the measure, known as a continuing resolution, would "ensure continuous funding for the federal government," and would "provide the resources necessary to continue normal operations through February the 8th."If the short-term measure is approved by both chambers of Congress, it would head to President Donald Trump's desk for his signature and prevent a partial government shutdown.Congress is currently in a race against the clock to prevent a partial shutdown when funding expires for several key government agencies at midnight on Friday.Republicans and Democrats on Capitol Hill have made clear they don't want a shutdown, but had been at an impasse over the President's demand for billion in funding for his long-promised wall at the US-Mexico border.Democrats have made clear that figure is a non-starter for them and any spending bill would need at least some Democratic votes to pass in the Senate.Of course, no spending measure is final until the President signs it.But on Tuesday, the White House appeared to step away from the brink of a shutdown.White House Press Secretary Sarah Sanders said Tuesday morning during an interview with Fox News that, "We have other ways that we can get to that billion (for a border wall)."Senate Democratic Leader Chuck Schumer sounded optimistic that a shutdown could be averted in remarks on the Senate floor on Wednesday."Yesterday we made some progress," he said, adding, "Thankfully, President Trump appears to have backed down from his position for billions in direct appropriations for a border wall." 1824

ROCKFORD, Illinois — A U.S. Marshal who served a search warrant at an Illinois hotel on Thursday died from his injuries.Officials said Floyd E. Brown, 39, shot the McHenry County deputy through the door of the hotel room. He then fled in a silver vehicle. Authorities chased Brown at about 100 miles per hour on Interstate 55. Brown allegedly brandished a gun and pointed it at police during the pursuit, which ended with him spinning out in Logan County, Illinois.Brown was holed up in his vehicle on I-55, which was shut down in both directions. As of 3:20 p.m. Eastern he was still barricaded inside the car.Police said Brown has opened his car door several times but is staying in it. They are also interviewing others in connection to the incident.A SWAT team and crisis negotiators were called to the scene where Brown is barricaded. 851
