Starlink accounts for roughly two-thirds of all active satellites in orbit.

The news comes as a Falcon 9 rocket, which launched from California last night, added 25 new satellites to the growing low Earth orbit constellation. [Spaceflight Now]It's a remarkable technical achievement, especially considering the tens of thousands of avoidance maneuvers satellites in the array need to complete to avoid crashing into each other. But it also comes at a great cost to radio astronomy and potentially to nearby spacecraft, while also raising the odds of an uncontrolled orbital chain reaction.Three to readU.K. officials race to contain the spread of a bacterial strain of meningitis behind a fatal outbreak in Kent, England.

The Etosha Pan is a roughly 1,800-square-mile (4,700 square kilometers) salt flat north of Namibia's capital, Windhoek. And it looks absolutely stunning from space.Quote of the day: "Think of your brain like a city: while the whole city is awake and active, a few specific 'neighborhoods' (brain regions) decide to turn off their lights for a second. If those neighborhoods are responsible for attention, you experience a lapse."Elaine Pinggal, a neuroscientist at Monash University, Melbourne, on how sleep-like brain activity can make our attentions lapse, and how adults with ADHD experience them much more often.Fun and gamesThis crossword by Senior Staff Writer Harry Baker took our Editor-in-Chief Alexander McNamara one minute and 55 seconds to complete.
