Where are you located? Here in the US they're incredibly rare and except parts that were used on other bikes that were actually sold in the US, you pretty much have to order from the UK. I had to order my BT-090's from thevisorsho

Traditional aerospace is not -- ULA has shown zero incentive towards driving down launch costs, their interest is more in keeping prices up on their USG gravy launches. Falcon is not fully reusable, there's a hard cost floor from the n

Well, a focus on being able to get to Mars basically means "figure out how to launch stuff extremely cheaply". I think they've been clear that SpaceX is not going to build a Mars base, they just count on it happening once y

Yes, the key is that all circular orbits at the same altitude must cross, and if the orbits cross there is a potential collision. Satellites at the same altitude can only avoid collisions by controlling the position in the orbit. Also, mean

Swarm is a subsidiary of SpaceX. Also, the Starlink modems need a huge amount of power compared to the Swarm network, not really a similar application.

I love IKEA but I'd have to disagree with their QA being top notch. I can't keep track of how many times I've had to go back because some piece in the flat pack was damaged.

That's fair, my point was just that you made it sound like "mature aerospace companies" were some special beings that didn't make mistakes. It's good to learn from other people's mistakes, but you also can'

Are you asserting that we gain better insight into the reliability of a system by thinking about it deeply rather than by observing it perform its function? Because I don't believe that for a minute. I'm not saying you can get by

A decade ago, the word was that SpaceX would go public "when we are reliably launching F9." Then Tesla went public and Elon decided he didn't want anything more to do with public companies. If anything, I think that statement

A mature aersopace company would have processes in place to check the material for these specs before use. Would a "mature aerospace company" also know to not use O-rings outside the temperature range specified by its engineers?

There were 135 space shuttle launches, of which 2 failed. There have been 162 launches of the F9 block 5 with 0 failures. Why do you think we have more knowledge of the long-tail probability of the Shuttle than F9? True, few of those F9 mis

This is true -- there is a lot of small number statistics in estimating the reliability of launch vehicles. And there are a lot of small risks you never see until you accumulate a lot of lunches. But that question is completely incidental t

No. All aircraft are designed and built to amazingly high standards because, in such as complex high-energy environment, there is no money to be saved by building less-than-perfect machines. But this is totally false. There are entirely d

At least in that case I'm the one deciding how long to keep the data. They can't get a warrant for data I don't have. I frankly don't understand why anyone would keep weeks of security camera footage around.
