April 29, 2021 at 09:37PM Nobody ever believed the pandemic would go easy on children. The virus might target them less directly than it targets older people, but other challenges—the loss of school, the loss of play, the loss of time with friends—would exact their own emotional toll. A study published April 29 in JAMA Network Open sheds light on how serious that harm has been. The work, led by psychologist Tali Raviv at Northwestern University, involved a survey of more than 32,000 caregivers looking after children from kindergarten to grade 12 in the Chicago public school system. The definition of “caregiver” was broad, including parents and grandparents as well as anyone 18 or older with principal responsibility of caring for children in a household. The sample group of the families was ethnically and racially diverse—39.3% white, 30.2% Latinx; 22.4% Black; and 8.1% mixed. The pivot point of the research was March 21, 2020: the day that in-person instruction ended in

April 29, 2021 at 12:26AM Few people think about the time Michael Collins didn’t go to the moon. Collins, who died of cancer on April 28 at age 90, is best remembered as Apollo 11’s command module pilot—in some ways the unluckiest man on the luckiest mission of all time. It was Apollo 11 that, in the summer of 1969, stuck the first crewed lunar landing, taking Neil Armstrong and Buzz Aldrin down to the surface, while Collins, bless him, stayed aloft in the command module orbiting 60 miles above, keeping his uniform clean and white while his crewmates got dirty on the endless gray beach that is the moon. All three men got the credit, all three got the parades and the medals and the world tour and the TV appearances. But Armstrong and Aldrin were the two truly limned in the light of history. Collins? Well, said many, his was a yeoman’s job. It wasn’t, of course, but never mind. History had other plans for Collins, and in some ways he had already made his mark—a much subtle

April 27, 2021 at 02:59PM Jeff Bezos’s Blue Origin filed a protest against NASA’s decision to award Elon Musk’s SpaceX a $2.9 billion award to develop a human-lander system to return astronauts to the moon. Blue Origin called on the U.S. Government Accountability Office to stay NASA’s deal with SpaceX and correct “errors” in the procurement process, according to the protest. Absent those problems, Blue Origin claimed that NASA would also have selected its proposal, which was submitted by a team that included Lockheed Martin Corp., Northrop Grumman Corp. and Draper, an engineering and avionics firm. “NASA has executed a flawed acquisition for the Human Landing System program and moved the goalposts at the last minute,” Blue Origin said Monday in a statement accompanying the challenge to NASA’s decision. “Their decision eliminates opportunities for competition, significantly narrows the supply base, and not only delays, but also endangers America’s return to the moon.” Th

April 24, 2021 at 12:14AM The United States convened 40 heads of state in a virtual climate summit this week, with the goal of eliciting commitments from attendees for radical reductions in carbon emissions. The U.S. pledged 50% reduction below 2005 levels by 2030, and others announced their own new targets — with the overall goal of putting the planet on track to carbon neutrality by 2050, the minimum needed to avert catastrophic climate change. But before patting themselves on the back for a job well done, the leaders of those 40 nations, many of them advanced economies , might want to take a look at some of the countries that didn’t make the guest list. Several developing and less stable nations are going in the opposite direction, building fossil-fuel energy infrastructure at this moment that will increase emissions for decades to come. Without their buy-in, the world going net-zero by 2050 is an unattainable goal. And environmentalists and climate finance experts

April 23, 2021 at 05:36PM Sian Proctor may owe her life to Apollo 11—literally. Born in Guam—the daughter of an engineer who worked at the local tracking station that helped NASA maintain communications with its lunar crews—she was the fourth child of a couple that she suspects did not plan for so many kids, and came into the world just nine months after Apollo 11 stuck its historic first moon landing. “I think I was a celebration baby,” she says with a laugh. “I wouldn’t be here if it wasn’t for human space flight.” Proctor herself has a lot to celebrate this year. Come September, if all goes to plan, the 51-year-old professor of geoscience at South Mountain University in Phoenix will climb aboard a SpaceX Crew Dragon spacecraft and rocket into low-Earth orbit, spending up to three days aloft before splashing down in the Atlantic Ocean. The mission, dubbed Inspiration4, won’t be the first aboard a SpaceX ship to carry crew; it won’t even be the second or the third. What it

April 23, 2021 at 12:28AM Rockets are built slowly—slowly and exceedingly carefully—which is in keeping with giant machines on which humans stake their lives and nations stake their prestige. In NASA’s cavernous Vehicle Assembly Building at Cape Canaveral, America’s next great moon rocket—the Space Launch System (SLS)—is being constructed with all that in mind. It is here too that TIME set up half a dozen cameras over the course of two months, capturing 3 million images for a time-lapse video that makes it possible to compress those months of work into just a few kinetic minutes. Under the eyes of the cameras, the rocket’s twin solid-fuel boosters came together—each of them 177 feet tall, weighing 1.6 million pounds and generating 3.6 million pounds (1.6 million kg) of thrust. Twenty-five percent taller than the solid boosters on the space shuttle, the twin engines are made of five separate segments, compared to the shuttle’s four. When they are completed, they will be attach

April 22, 2021 at 04:30PM When he was a child, James Owuor loved hearing the elders talk about the way life used to be. So it comes as something of a surprise that at 38, he is now the one tasked with the job of describing the Before Times in Kenya’s Rift Valley. Before Lake Baringo started to rise, before it flooded and stole everything he knew. “At the beginning, we just thought it was a bad rainy season, that the water would recede when the dry season came. It didn’t,” he says ruefully, peering over the edge of his motorized canoe at what used to be houses below the milky brown waters. Over the past decade, an unprecedented increase in annual rainfall—widely attributed to climate change —has raised the lake by 40 ft. (12 m), inundating nearly 22,000 acres and destroying homes, businesses and Roberts Camp, the lakeside resort where Owuor has worked for most of his adult life. In 2014, he watched the waters overtake the two-story-tall shorefront lodge. The restaurant went next
