I read that SpaceX's engines deliver a bit more thrust at a bit less mass than NASA engines. But the kicker was SpaceX's were 1/200th the cost. From the cost angle it's very interesting observing space activities going from mostly public to mostly private.

Ok, I will. You're alluding to two separate problems which are both pet peeves of mine. The less controversial one is that product marketing/communication is becoming all marketing and little communication. Why do landing pages, press releases and ads created by teams of highly paid professionals fail to clearly convey what something actually is (and is not) and why I should care?
The second problem is it's getting damn near impossible to discuss any aspect of a high profile company, product or even technology without the politics, personalities, or social impacts related to it swallowing everything. At minimum it's now normal, if not expected, to preface any discussion by signaling a position on {adjacent controversy}. Before the last decade, people would think always doing that was weird.
I'll give an example avoiding current 'triggers', in a discussion on foreign policy you could observe ex-president Richard Nixon's China foreign policy was new, bold and successful - some might agree and others disagree - but no one would feel the urgent need to signal their views on Watergate or the fact Nixon was universally considered by far the worst U.S. president ever (as well as a reprehensible morally toxic personality). Enlightened people could handle discussing different aspects of things without fearing that NOT diverting onto the 'obviously problematic' adjacent aspect might somehow be taken as personally endorsing it.
My granddad was in the military in WWII and would always mention how strange it felt to have a Toyota now and that it and VW were very frowned on by people in the war for a long time. Probably same would be felt about Tesla the nazi salute and otherwise support even back in the 80s.
That's not an example which disproves my point, in fact, it makes the point perfectly. Which is: it isn't appropriate or normal when people hyper-overreact to something as inconsequential as an erratically eccentric Tech Bro's juvenile trolling (or thoughtlessly stupid unplanned gaffe, depending on who you believe) in a way similar to, as you've insightfully pointed out, the reaction of a traumatized survivor of the biggest, most consequential and horrible single event in all of human history - people who watched their friends and families die violent brutal deaths, and in many cases witnessed systematic genocide against their entire race at scales beyond imagining. That's how some people now react to stupid, wrong, offensive words and gestures by fucking morons and trolls on Twitter and TikTok. Thank you. That's actually a much better example of my point.
I think Elon is a complete nutjob but, seriously, these are NOT remotely the same level or scope. Your granddad was a literal, fucking hero - and obviously made of much sterner stuff than (some) people today. Your grandad said seeing Enemy Vehicles around town was "strange." He didn't hold candlelight vigils in front of Volkswagen and Toyota dealers, he didn't harangue VW owners in the supermarket parking lot, or need to signal about it in every, single, conversation where those countries, companies or cars were mentioned.
If he had protested and harangued, I'd understand that level of reaction and constant obsession. War zone PTSD is terrible and never goes away. Oh, and tens of millions died in, arguably, the biggest, worst thing... ever? Yeah, I'm okay if Gramps over-reacts a little. But apparently you granddad didn't think over-reacting was called for or appropriate.
To make your implications explicit:
Do you agree with the anti defamation league position you're claiming that that wasnt a nazi salute?
Do you think it was anything like one? Was it enough to be in bad taste and worth assuring people it was not afterward? If it was you would you have tried to clear up the misunderstanding after?
Do you think the person you posted this in reply to should change their mind about musk and his actions here because they are genuinely misunderstanding a good faith situation?
I don't know what you think is supposed to happen after Citizens United v FEC. Corporate money is protected speech. Therefore doing business with a given corporation is inherently a political act. If you don't like it, campaign to overturn that decision, but bitching at the people who are correctly reacting to changes in the political system is not going to accomplish anything, ever.
We do education outreach to K-16 learning institutions around the world. There are many things that can be studied in the near absence of gravity. Fluids are a huge area of research (surface tension, sedimentation, etc). We germinate seeds and look for genetic changes, people study brain organoids, artificial retinas, crystals, et al
