"Starlink is beginning a significant reconfiguration of its satellite constellation focused on increasing space safety," announced Michael Nicolls, Starlink's vice president of engineering: "We are lowering all Starlink satellites orbiting at ~550 km to ~480 km (~4400 satellites) over the course of 2026. The shell lowering is being tightly coordinated with other operators, regulators, and USSPACECOM. Lowering the satellites results in condensing Starlink orbits, and will increase space safety in several ways... Starlink satellites have extremely high reliability, with only 2 dead satellites in its fleet of over 9000 operational satellites. Nevertheless, if a satellite does fail on orbit, we want it to deorbit as quickly as possible. These actions will further improve the safety of the constellation, particularly with difficult to control risks such as uncoordinated maneuvers and launches by other satellite operators. But orbits are being lowered for another reason (besides quick de-orbiting), notes Space.com. Within the next four years the period of least solar activity is expected, a period which coincides with decreased atmospheric density, Nicolls added, "which means the ballistic decay time at any given altitude increases." [Bringing the satellites lower] will mean a >80% reduction in ballistic decay time in solar minimum, or 4+ years reduced to a few months," Nicolls wrote in his X post. "Correspondingly, the number of debris objects and planned satellite constellations is significantly lower below 500 km, reducing the aggregate likelihood of collision...." The downward migration in 2026 involves roughly half of SpaceX's Starlink megaconstellation, which currently consists of nearly 9,400 operational spacecraft (though that number is always growing).

"While a growing number of U.S. employers are mandating workers return to the office five days a week," reports the Washington Post, "some companies say AI is saving them enough time to launch or sustain a four-day workweek. "More companies may move toward a shortened workweek, several executives and researchers predict, as workers, especially those in younger generations, continue to push for better work-life balance." And "several companies — especially those with a largely remote workforce — have adjusted their work rhythm after delegating many tasks to AI..." AI "has such a potential to have so much labor savings, you'll see firms shift to a four-day week in an evolutionary way," said Juliet Schor, an economist and sociologist at Boston College who has studied the subject. "There's enough social consensus that people are exhausted and stressed...." Small and medium businesses often adopt shortened workweeks to compete with big salaries for new hires and retention, Schor said. That's how Peak PEO, a London-based service that helps companies expand globally with teams in different locations, thought about its strategy... CEO Alex Voakes said that job openings that used to get two applications jumped to 350 after the change. "Some of the world's most influential business leaders have publicly suggested the shift may be inevitable," adds Fortune: Jamie Dimon, the CEO of JPMorgan Chase, has said advancing technology could eventually push the workweek down to just three-and-a-half days. Microsoft cofounder Bill Gates has gone further, openly questioning whether a two-day workweek could be the future. Elon Musk has taken the idea to its logical extreme, positing that the need to work altogether could cease... Tech innovation could "probably" lead to a transition toward four-day workweeks, [Nvidia CEO Jensen] Huang said on Fox Business in August...
