Nerd out with Elon Musk, you nerds. I found it fascinating.
Anyone interested in SpaceX ought to check out this book. Started a couple of nights ago, fascinating.

Pretty sure there's a ton of "explainer" math already done on this.
One metric worth noting is nothing living could survive the spin-up
The Russians just blew up one of their satellites with an antisatellite missile. Several thousand pieces of debris now in LEO, posing a possible risk to the ISS.
Where's Sandra Bullock when you need her?
Ok space fans, I saw something last night that I'll ask you about:
Clear starry night, roughly 7 PM eastern a nice meteoroid catches my eye so I'm looking up, and few seconds later I see a double strip of lights with a single brighter light on each end. It was making it's way across the sky at speed I would guess was analogous to near earth orbit, or maybe faster and lower. In perspective, it was longer than anything I'm aware of up there, but I'm no satellite expert. It kind of looked like a zipper, sort of. Lights white or maybe slightly tinged like LED blue.
I watched it for about 10 seconds and it disappeared before crossing to horizon. I guess this could just mean sunlight shining on it was blocked by Earth or someone shut the lights off. Maybe not a UPO, but unidentifiable by me. Also of course no way to determine actual altitude, so size hard to determine. But it seemed very big & long or very low, as If a sky banner plane was towing a very long banner w LED lights.
Anyone have an idea what I might have seen?
The Webb may be the biggest collection of single-points-of-failure to ever be launched into space.
There's gonna be a lot of tight sphincters waiting to see if it actually unfurls properly
So far so good.
