Mostly the heavy steel booster cases were reused, iirc. I don’t believe the reuse process was ever cost-effective. As for the Shuttles themselves, so much inspection and refurb was required that it made reuse look unattractive. SpaceX is ge

As a kid, I acquired a few of these from my grandparents' farm. At some level it struck me as odd that they shared so many common features and details. It was many years before finally hearing about the "All American 5" and t

Those are some pretty serious coax lines. I had no idea anything like that existed. The parts and labor to run lines like that must be… substantial. Imagine trying to screw one of those into your cable modem!

Any thoughts on the least intrusive yet modern simple graphics library for Python? I've been wanting to play with some of these things but never quite find the time/motivation to deal with the "getting started" overhead.

It varies. I’ve been a SpaceX (and thus Elon) fan since they were unsuccessfully launching Falcon 1’s. EM’s willingness to share information with the space fan community won him a lot of admirers. I was certainly willing to overlook many of

Yes, exactly. Even before this issue, ATX 3.0 felt like a missed opportunity to start phasing in 48v DC power. Very disappointing.

Is this really better than producing something like synthetic methane (ie, natural gas?) We have vast experience using this as a fuel already. It does contain carbon (methane is CH4) so you’d need to produce it using carbon from the atmosph

I'm with you, Sam. I loved going to my office, loved my commute (by bicycle or by train and walking), loved separating home from work life. And now I recognize that is probably gone forever. My guess is that we are giving up more than

I can’t help but feel like some responders here have confused “progress” with “change”. The former always implies the latter, but the reverse is not necessarily true: not all change is progress.

I’m a big fan of SpaceX and (when he can keep his mouth shut about US politics and a dozen other things) Elon Musk, but they’re hardly the first ones to launch without regular scrubs. ULA does it all the time. So does arianespace. The Russi

It’s wrong because hydrogen in the first stage optimized for things you don’t care about, namely propellant mass. In exchange, you get heavier tanks, physically larger engines, and (obviously) more complex operations. Yes, it has the highes

Consequences of choosing the wrong first stage fuel (hydrogen) are many. Those tiny molecules want nothing more from life than to sneak through the smallest of openings. Well, possibly second to mating violently with oxygen.

For now, at least, Apple doesn't serve the upper end of the market with anything remotely affordable. I bought an M1 Mini early on and it's been an absolutely wonderful machine. But it's got 16 GiB RAM and a few ports on the

Fairly sure AMD has already indicated that an "extra cache" model(s?) of Zen 4 consumer chips will appear down the road.

This stuff is hard. I'm obviously not an SLS fan, but first launch of a new rocket? So many things have to go right. Granted, they're playing on hard mode by choosing a poor first stage fuel (hydrogen), but it's a tough probl

To be fair, it's pretty common for "mature" organizations to reach orbit on the first try. SpaceX had three Falcon 1 failures before their first success, and a few other startups have shown similar numbers. On the other hand,

Solid rockets will never be effectively reusable. They may have made sense early on, but in 2022 they're clearly an evolutionary dead end.

This! About ten years ago, I had to make a late visit to a rental property in a rougher part of Atlanta. Walking back to my 1995 Accord Ex Coupe w/ manual gears (they probably made about a dozen of these…) some kids appeared out of the

I'd forgotten about the 80376 but it hits at a question I've occasionally had over the last few years. Why have we not seen a "modernized" x86 CPU that strips out everything pre-AMD64? The answer seems likely to be one o

Data may have said it in TNG, but pretty sure this originated with the 1983 film “WarGames” ( https://en.m.wikipedia.org/wiki/WarGames ).
