SpaceX's Falcon Heavy rocket, the most powerful vehicle flying today, just passed a key milestone by launching its first-ever mission for a paying customer.The rocket took off Thursday from Kennedy Space Center in Florida just after 6 pm ET. It delivered a 269

Sen. Bernie Sanders on Thursday added progressive meat to the bones of the Green New Deal with the release of his comprehensive .3 trillion climate change program ahead of a campaign stop in Paradise, California, the city leveled by a devastating 2018 wildfire.Sanders was an early backer of the activist-inspired Green New Deal framework and introduced, with Reps. Alexandria Ocasio-Cortez and Earl Blumenauer, a resolution in July to declare climate change a national emergency."Young people, advocates, tribes, cities and states all over this country have already begun this important work," the campaign says in its new pitch, "and we will continue to follow their lead."The Sanders plan channels the rhetoric of the climate movement, calling for a World War II-style mobilization to halt and reverse the effects of global warming over a decade. In the process, the campaign claims, it would create 20 million new jobs in "steel and auto manufacturing, construction, energy efficiency retrofitting, coding and server farms, and renewable power plants." Sanders' blueprint will be compared to proposals put forward by Sen. Elizabeth Warren and Washington Gov. Jay Inslee, who released a robust suite of cross-sector plans before ending his campaign on Wednesday.In a CNN poll from late April, 96% of potential Democratic voters said "aggressive action to slow the effects of climate change" was somewhat or very important -- the closest to a unanimous finding in the survey. The Democratic National Committee has so far not hosted a climate-specific debate, but 10 of the 2020 primary candidates will take part in a September 4 CNN town hall focused exclusively on the crisis.During his time in office, President Donald Trump has rolled back dozens of environmental rules and regulations. Sanders in his plan promises to "aggressively enforce" the Clean Air Act, through the Environmental Protection Agency, to restrict dangerous emissions.But the proposals unveiled Thursday go much further.Sanders' prime targets include meeting the Intergovernmental Panel on Climate Change's goal of 100% renewable energy for electricity and transportation by 2030; cutting domestic emissions by 71% over that period; creating a 6 billion electric "smart grid;" investing 0 billion in the Green Climate Fund; and prioritizing what activists call a "just transition" for fossil fuel workers who would be dislocated during the transition.The Vermont independent would also cut off billions in subsidies to fossil fuel companies and impose bans on extractive practices, including fracking and mountaintop coal mining, while halting the import and export of coal, oil and natural gas. Additionally, he would use his Justice Department and the Securities and Exchange Commission to pursue criminal and civil cases against energy companies that hid or withheld information -- over decades -- about the damage their businesses were doing to the environment.Sanders in 2015 and 2016, during his first presidential campaign, memorably called climate change the foremost national security threat. In recent remarks on the campaign trail, he has promised to reassert US power internationally by taking a more assertive role in climate talks."Climate change cannot only be addressed by the United States. It is a global issue," Sanders said this week in Iowa. "But my promise to you is, instead of ignoring this issue as Trump does, I will help lead the world in bringing countries together to address the issue."The proposal is the most in-depth to date from Sanders, who says it will "pay for itself over 15 years" and includes new details on the potential funding sources.The most significant, at an estimated .4 trillion, would come from revenue generated by the sale of clean energy -- which will be administered by publicly owned utilities -- between 2023 and 2035. Before that, Sanders would cut military spending used to protect global energy interests by more than .2 trillion while hitting up fossil fuel companies for more than trillion in "litigation (against polluters), fees, and taxes." An additional .3 trillion, the campaign says, would be raised from the taxes paid on the 20 million new jobs it promises to create.Part of that money would go toward mitigating the damage already done by climate change -- with 2 billion set aside for coastal communities under threat and an additional billion going toward firefighters to combat a spike in dangerous wildfires like the one in Paradise.To deliver the political will for such a radical transformation, Sanders, as he has throughout his presidential campaigns, is counting on the youth-led activists and progressive movements that he has often inspired and, now, hopes to count on as a source of electoral strength.Their continued vigor and ability to successfully pressure elected officials is written into the plan."We will do this," the campaign says, "by coming together in a truly inclusive movement that prioritizes young people, workers, indigenous peoples, communities of color, and other historically marginalized groups to take on the fossil fuel industry and other polluters to push this over the finish line and lead the globe in solving the climate crisis." 5251

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

Steve Easterbrook is out as McDonald's CEO and president after the board determined that he violated company policy, the company said on Sunday.Easterbrook, who became CEO in 2015, "demonstrated poor judgment involving a recent consensual relationship with an employee," McDonald's said in a statement.He has "separated" from the company and has been replaced in both roles by Chris Kempczinski, effective immediately. Kempczinski, who joined McDonald's in 2015 and was most recently president of McDonald's USA, said in a statement that he is "energized by this challenge" and looks forward "to guiding McDonald's continued success."In an email sent to McDonald's employees, Easterbrook expressed regret over the relationship."As for my departure, I engaged in a recent consensual relationship with an employee, which violated McDonald's policy," Easterbrook wrote. "This was a mistake. Given the values of the company, I agree with the board that it is time for me to move on. Beyond this, I hope you can respect my desire to maintain my privacy."He also said that his time as CEO "have been the most fulfilling years of my working life."The board said it is confident in Kempczinski's ability to lead the company."Chris takes the reins of this great company at a time of strong, sustained performance,' said Enrique Hernandez Jr., chairman of McDonald's board of directors, in a statement. "The board has every confidence that he is the best leader to set the vision and drive the plans for the company's continued success."In his email, Easterbrook described Kempczinski as "the ideal person to take on the role of CEO."Joe Erlinger, who was most recently president of international operated markets for McDonald's and has been with the company since 2002, is replacing Kempczinski as president of McDonald's USA.Easterbrook had been leading McDonald's in an aggressive modernization plan. With Easterbrook at the helm, the company has rapidly remodeled stores to include digital menu boards, and 2013

Scientists working for a NASA-funded project at the University of Arizona said that a possible "mini moon" is currently orbiting the Earth. Kacper Wierzchos of the Catalina Sky Survey tweeted this week that an object, 2020 CD3, has been captured by Earth's gravitational pull, and is temporarily in orbit around the Earth. The object is not very large, only 6 to 11 feet, Wierzchos said, but he added it is still an extraordinary discovery. "it's a big deal as out of ~ 1 million known asteroids, this is just the second asteroid known to orbit Earth (after 2006 RH120, which was also discovered by the Catalina Sky Survey)," he tweeted. 2020 CD3 began orbiting the Earth three years ago. Elon Musk, the head of Tesla, jokingly tweeted, "It’s not mine." Tesla sent a Roadster into space in 2018. BIG NEWS (thread 1/3). Earth has a new temporarily captured object/Possible mini-moon called 2020 CD3. On the night of Feb. 15, my Catalina Sky Survey teammate Teddy Pruyne and I found a 20th magnitude object. Here are the discovery images. 1049
