"Le projet prévoit des satellites opérant entre 500 et 2 000 kilomètres d’altitude en orbite terrestre basse. Certaines de ces orbites sont conçues pour bénéficier d’une exposition quasi permanente au soleil. Le public peut d’ailleurs actuellement soumettre des commentaires sur cette proposition."

In a few years, when enough #satellites are launched up into #Earth orbit, we won't be able to peer out into the #universe, nor will the #extraterrestrials be able to see us either. *shrug*

Interesting comparison ... the total cost to deploy a 1 GW data center in space vs. ground based. Satellite based ~ $51B, including launch and five years of operational expenses. Ground based ~ $16B over the same period.

Note: Satellite based #'s assumes leveraging multi-purpose space craft aka outfitting Starlink craft with space hardened ASICs/GPUs vs. launching dedicated data center satellites. https://spectrum.ieee.org/orbital-data-centers #Satellites #DataCenters #Space #Orbit #OrbitalDataCenter #Power #SolarPower #SpaceCraft

We’re putting more stuff into #space than ever. Here’s what’s up there.
People started putting gear up there in 1957, and now it’s a real habit. Humans live in an orbiting metal bubble. In last five years, the number of active #satellites in space has increased from barely 3,000 to about 14,000—and climbing. The biggest use case: “megaconstellations” like Elon Musk’s Starlink internet service, which by itself has nearly 10,000 satellites in #orbit.

We’re putting more stuff into space than ever. Here’s what’s up there.

There’s a thin layer of human-made stuff enrobing the planet. A data dive into the anthroposphere.

"The big fear is that future collisions will cause a domino effect where Earth’s orbit becomes cluttered with tiny, high-speed bits of metal. That could create a near-impenetrable layer of debris that would make space launches so dangerous it would essentially trap humans on Earth"

Like that's not a good thing?
Some v good graphics too.

‘This feels fragile’: how a satellite-smashing chain reaction could spiral out of control

Today, the space around Earth can no longer be considered empty. More than 30,000 objects are in orbit, and that figure is rising exponentially
