Congestion in space could cause big problems on Earth

Share this story

With each new satellite that reaches orbit, the space above our heads gets a little more congested. There are about 3,000 active satellites in use today, but that number is changing quickly, especially as companies like Starlink send up 60 small satellites in a single launch. Add the 20,000 or so bits of orbital debris that authorities are actively tracking, and the image of a limitless expanse of space above the Earth starts to feel a little different.

Moriba Jah is a researcher at the University of Texas at Austin who’s on a mission to make the stakes of orbital congestion abundantly clear. He built a visualizer called AstriaGraph that displays the positions of all actively-tracked objects in the sky. He also designed a real-time graph that shows just how close objects get to one another as they whip around the planet, sometimes 15 times faster than a bullet.

The Big Bad in all of these calculations is a collision: two objects slamming into each other at terrific speeds, creating numerous bits of new debris. Any one of those new pieces of junk could go on to threaten other operational hardware. Whether such collisions could amplify exponentially and wipe out entire orbits — the so-called “Kessler syndrome” — is up for debate. Jah, for one, isn’t suggesting that an orbital apocalypse is around the corner. But some kind of satellite-industry reckoning may need to be.

The Verge spoke with Jah about his projects and efforts. Check out the video above to see AstriaGraph and more in action.

California Governor Gavin Newsom vetoes the state’s “BitLicense” law.

The bill, called the Digital Financial Assets Law, would establish a regulatory framework for companies that transact with cryptocurrency in the state, similar to New York’s BitLicense system. In a statement, Newsom says it’s “premature to lock a licensing structure” and that implementing such a program is a “costly undertaking:”

A more flexible approach is needed to ensure regulatory oversight can keep up with rapidly evolving technology and use cases, and is tailored with the proper tools to address trends and mitigate consumer harm.

Get ready for some Netflix news.

At 1PM ET today Netflix is streaming its second annual Tudum event, where you can expect to hear news about and see trailers from its biggest franchises, including The Witcher and Bridgerton. I’ll be covering the event live alongside my colleague Charles Pulliam-Moore, and you can also watch along at the link below. There will be lots of expected names during the stream, but I have my fingers crossed for a new season of Hemlock Grove.

Looking for something to do this weekend?

Why not hang out on the couch playing video games and watching TV. It’s a good time for it, with intriguing recent releases like Return to Monkey Island, Session: Skate Sim, and the Star Wars spinoff Andor. Or you could check out some of the new anime on Netflix, including Thermae Romae Novae (pictured below), which is my personal favorite time-traveling story about bathing.

If you’re using crash detection on the iPhone 14, invest in a really good phone mount.

Motorcycle owner Douglas Sonders has a cautionary tale in Jalopnik today about the iPhone 14’s new crash detection feature. He was riding his LiveWire One motorcycle down the West Side Highway at about 60 mph when he hit a bump, causing his iPhone 14 Pro Max to fly off its handlebar mount. Soon after, his girlfriend and parents received text messages that he had been in a horrible accident, causing several hours of panic. The phone even called the police, all because it fell off the handlebars. All thanks to crash detection.

Riding a motorcycle is very dangerous, and the last thing anyone needs is to think their loved one was in a horrible crash when they weren’t. This is obviously an edge case, but it makes me wonder what other sort of false positives we see as more phones adopt this technology.

Ford is running out of its own Blue Oval badges.

Running out of semiconductors is one thing, but running out of your own iconic nameplates is just downright brutal. The Wall Street Journal reports badge and nameplate shortages are impacting the automaker's popular F-series pickup lineup, delaying deliveries and causing general chaos.

Some executives are even proposing a 3D printing workaround, but they didn’t feel like the substitutes would clear the bar. All in all, it's been a dreadful summer of supply chain setbacks for Ford, leading the company to reorganize its org chart to bring some sort of relief.
