Meantime, in OTHER news, in this case of an older bent, the absolutely brilliant debut album by , one of my favorite acts then and now, is now out in a hyperexpanded edition available for only 20 euros digitally. Well, well worth it. https://orbitalofficial.bandcamp.com/album/orbital-the-green-album-expanded

- – Optical Delusion (Label: Orbital). Considering they’ve been raving for more than 30 years, brothers Phil and Paul Hartnoll still sound energized on this year’s set of electronic thrill rides. From the pop inflections of “Are You Alive?” to the aggressive shakedown of “You Dirty Rat,” collaborators Penelope Isles, Sleaford Mods and others help vary the mood and tempos on an album showing no signs of flagging since 90s classics like Snivilization.

While we are talking about Musk and Starlink, let's discuss the Kessler Syndrome.

Some evening not too long from now you may look up, and instead of the stars and a few Starlink satellite trains marching along, you might see a night sky filled with brilliant sparkles. You check the news and learn the International Space Station has been destroyed as well humanity's weather and other Earth observation satellites. What's happened?

@mastodonmigration space debris has been a problem everyone watched coming

"The problem of space junk adds up to around 200 tons of our trash. The clutter in Earth's orbit includes defunct spacecraft, spent rocket boosters and items discarded by astronauts such as gloves, wrenches and toothbrushes."

Reaching means accelerating up to around 28,000kph (22 times the speed of sound). A five-gram 🔩 hitting at packs as much 💥 as a 200kg weight dropped from the top of an 18-storey building.

None of the dozen or so 🇪🇺 companies have actually attempted an attempt yet, it can be difficult to tell who is making real and who is not. Many, if not most, will probably never reach orbit. When a company raises $250 million 💰 or more, it is on a viable path toward building a vehicle that will one day reach orbit. https://arstechnica.com/science/2023/03/a-front-runner-emerges-in-the-european-small-launcher-race
