HAWTHORNE (CNS) - A planned launch Saturday by Hawthorne-based SpaceX to deploy 57 internet satellites into orbit has been postponed for a third time to "allow more time for checkouts," the company tweeted.No new launch date was announced, but SpaceX officials said their launch team was working to identify the next earliest launch opportunity.The 10th Starlink mission, part of an effort to provide low-cost internet access, was originally scheduled for June 26 from Cape Canaveral in Florida but was scrubbed at the last minute to allow for more pre-flight equipment checks. SpaceX tried again Wednesday morning, but that launch had to be canceled due to bad weather.Saturday's launch had been set for 7:54 a.m. California time.When it eventually lifts off, the Falcon 9 rocket will carry 57 Starlink internet satellites as part of SpaceX's planned array to provide worldwide low-cost internet access, particularly in underserved areas.This 10th launch will increase the Starlink array to nearly 600 satellites in orbit. It's unclear exactly how many satellites will ultimately be included in the constellation. SpaceX founder Elon Musk has said previously that the service could begin operating when it reaches 1,000 satellites, and the company has already begun soliciting people to be "beta" testers. But the more satellites that are deployed will mean more comprehensive internet coverage.In addition to the 57 Starlink satellites, the SpaceX rocket will also carry a pair of satellites for Spaceflight Industries on behalf of Earth- observation company BlackSky.BlackSky is in the process of building its satellite array, with four already in orbit. The launch will increase the array to six, and the company has an initial goal of launching 16 by early next year. The array could ultimately have as many as 60 satellites, but timing on that expansion hasn't been determined.When the launch occurs, SpaceX will again attempt to recover the first stage of the Falcon 9 rocket by landing it on the company's "Of Course I Still Love You" barge in the Atlantic Ocean. The recovery process is an effort to slash the costs of launches by allowing rockets to be reused.The first stage of the rocket being used for the Starlink mission was used in four previous SpaceX launches, including two Starlink satellite missions. 2329

General Electric is cutting its stock dividend for only the second time since the Great Depression.The company announced Monday that it will cut the dividend from 24 cents to 12 cents per share.GE is one of America's most widely held stocks, and countless shareholders, including retirees, rely on the dividend payments. But the company is under enormous pressure to restore investor confidence. The stock has lost a third of its value this year.The company also cut its dividend in 2009, during the Great Recession. But dividend cuts are rare these days. Many companies are increasing them because the U.S. economy is healthy and the stock market is booming.GE plans an update for investors Monday morning and is expected to detail a strategy to stabilize the company by slashing costs and selling more businesses.It has already gotten rid of its real estate portfolio, its dishwasher and appliance business, and media properties NBC and Universal Studios. More recently, it unloaded its water business and a unit that makes electrical equipment for utilities.Even the light bulb division is up for sale as part of GE's mission to focus on being a modern industrial company that sells things like jet engines, power plants and MRI machines.GE confirmed on Friday that job cuts, some of which have begun, are part of a previously announced plan to cut costs by billion.  1386

Gregory Minott came to the U.S. from his native Jamaica more than two decades ago on a student visa and was able to carve out a career in architecture thanks to temporary work visas.Now a U.S. citizen and co-founder of a real estate development firm in Boston, the 43-year-old worries that new restrictions on student and work visas expected to be announced as early as this week will prevent others from following a similar path to the American dream.“Innovation thrives when there is cultural, economic and racial diversity,” Minott said. “To not have peers from other countries collaborating side by side with Americans is going to be a setback for the country. We learned from Americans, but Americans also learn from us.”Minott is among the business leaders and academic institutions large and small pleading with President Donald Trump to move cautiously as he eyes expanding the temporary visa restrictions he imposed in April.They argue that cutting off access to talented foreign workers will only further disrupt the economy and stifle innovation at a time when it’s needed most. But influential immigration hard-liners normally aligned with Trump have been calling for stronger action after his prior visa restrictions didn’t go far enough for them.Trump, who has used the coronavirus crisis to push through many of his stalled efforts to curb both legal and illegal immigration, imposed a 60-day pause on visas for foreigners seeking permanent residency on April 22. But the order included a long list of exemptions and didn’t address the hundreds of thousands of temporary work and student visas issued each year.Republican senators, including Tom Cotton of Arkansas and Ted Cruz of Texas, argue that all new guest worker visas should be suspended for at least 60 days or until unemployment has returned to normal levels.“Given the extreme lack of available jobs,” the senators wrote in a letter to Trump last month, “it defies common sense to admit additional foreign guest workers to compete for such limited employment.”Trump administration officials have been debating how long the forthcoming order should remain in place and which industries should be exempted, including those working in health care and food production.But the White House has made it clear it’s considering suspending H-1B visas for high-skilled workers; H-2B visas for seasonal workers and L-1 visas for employees transferring within a company to the U.S.In recent weeks, businesses and academic groups have also been voicing concern about possible changes to Optional Practical Training, a relatively obscure program that allows some 200,000 foreign students — mostly from China and India — to work in the country each year.Created in the 1940s, OPT authorizes international students to work for up to one year during college or after graduation. Over the last decade, the program has been extended for those studying science, technology, engineering and mathematics so that they can now work for up to three years.While congressional Republicans have been some of the strongest supporters of eliminating the program, 21 GOP House lawmakers argued in a letter to the Trump administration this month that OPT is necessary for the country to remain a destination for international students. They said foreign students and their families pump more than billion annually into the economy even though the students represent just 5.5.% of U.S. college enrollments.Companies and academic institutions also warn of a “reverse brain drain,” in which foreign students simply take their American education to benefit another nation’s economy.Some critics say OPT gives companies a financial incentive to hire foreigners over Americans because they don’t have to pay certain federal payroll taxes.The program also lacks oversight and has become a popular path for foreigners seeking to gain permanent legal status, said Jessica Vaughan, policy director at the Center for Immigration Studies, a Washington group advocating for strict immigration limits.“The government does not require that there be actual training, and no one checks on the employer or terms of employment,” she said. “Some of the participants are career ‘students,’ going back and forth between brief graduate degree programs and employment, just so they can stay here.”Xujiao Wang, a Chinese national who has been part of the program for the past year, said she doesn’t see any fault in trying to build her family’s future in the U.S.The 32-year-old, who earned her doctorate in geographic information science from Texas State University, is working as a data analyst for a software company in Milford, Massachusetts.She’s two months pregnant and living in Rhode Island with her husband, a Chinese national also working on OPT, and their 2-year-old American-born daughter. The couple hopes to eventually earn permanent residency, but any change to OPT could send them back to China and an uncertain future, Wang said.“China is developing fast, but it’s still not what our generation has come to expect in terms of freedom and choice,” she said. “So it makes us anxious. We’ve been step-by-step working towards our future in America.”In Massachusetts, dismantling OPT would jeopardize a fundamental part of the state’s economy, which has been among the hardest hit by the pandemic, said Andrew Tarsy, co-founder of the Massachusetts Business Immigration Coalition.The advocacy group sent a letter to Trump last week pleading for preservation of the program. It was signed by roughly 50 businesses and colleges, including TripAdvisor and the University of Massachusetts, as well as trade associations representing the state’s thriving life sciences industry centered around Harvard, MIT and other Boston-area institutions.“We attract the brightest people in the world to study here, and this helps transition them into our workforce,” Tarsy said. “It’s led to the founding of many, many companies and the creation of new products and services. It’s the bridge for international students.”Minott, the Boston architect, argues that the time and resources required to invest in legal foreign workers, including lawyers’ costs and visa processing fees, exceeds any tax savings firms might enjoy.DREAM Collaborative, his 22-person firm, employs three people originally hired on OPT permits who are now on H-1B visas — the same path that Minott took early in his career.“These programs enabled me to stay in this country, start a business and create a better future for my family,” said the father of two young American-born sons. “My kids are the next generation to benefit from that, and hopefully they’ll be great citizens of this country.”___Associated Press reporters Collin Binkley in Boston and Jill Colvin in Washington contributed to this story. 6805

Her name was Jakelin Caal Maquin. She had traveled with her father from a rural indigenous community in Guatemala's impoverished Alta Verapaz region.They were among a group of 163 migrants detained by Border Patrol agents the night of December 6 -- three days after her birthday -- in a remote area of the New Mexico desert, officials said.Two days later, 7-year-old Jakelin was dead, Customs and Border Protection's officials said Friday. She had vomited and stopped breathing while in Border Patrol custody. Jakelin later went into cardiac arrest and suffered brain swelling at a Texas hospital."Without the lifesaving measures undertaken by Border Patrol, this child would have likely died in the desert alone without any medical care whatsoever," a Department of Homeland Security official said Friday. "The entire department is heartbroken by this loss of life."The department's Inspector General's office is investigating the death and said its findings will be released publicly. The US government officials spoke on a conference call with reporters and insisted they not be identified by name. 1109

HAWAII — There was a close call at a preschool in Hawaii.The Hawaii State Department of Health says a classroom assistant mistook Pine-Sol for apple juice while serving snacks.The assistant at Kilohana United Methodist Church in East Oahu was preparing a snack for the children and grabbed a bottle of the cleaning liquid from a clean-up cart in the kitchen on November 27.The assistant apparently mistook it for apple juice because of its similar color, the school's director told the health department inspector.A classroom teacher smelled the cleaning product and stopped students from drinking it.EMS evaluated three students who took small sips of the cleaning liquid, but none of them needed treatment.One parent whose child was in the class says she was shocked a mistake like that could happen.The State Health Department says each year about a dozen people accidentally ingest Pine-Sol, and half of them are kids.CNN contributed to this report. 966
