Why do something annoying once when you can do it twice for twice the outrage?

Last night, just before full darkness, I was walking through the woods around our home in rural western Washington state and quite suddenly I'm looking at a surprised black bear. It was perhaps 4 meters away and immediately stood up a

Does anyone have a sense of how practically difficult it would be to detect an active Starlink installation?

This is outstanding, thank you.

Neat, do you have a quick reference handy? Thanks!

> SpaceX has had the same exact cost overruns as Boeing.... Why do you believe this is the case?

by Diederich 2y ago
This is very technically correct but also misleading. In the last test flight, Starship reached a velocity of 7.3km/s. Orbital velocity is 7.8km/s. Why didn't they make it to 7.8km/s? Because they choose not to. Stars

Did you see the amendment at the top? "Update: on 9 September 2023, Walter Isaacson said his biography’s claim about Starlink and Crimea was based on “mistaken” information [see footnote]" Here's a more accurate summary: htt

I think we're in agreement about Tesla. I believe that Musk's bullshit has greatly harmed that company. At the same time, I don't think it's hurt SpaceX very much.

by Diederich 2y ago
Do you think Musk's antics are having a notable negative effect on SpaceX? There's no doubt that's the case with Tesla.

by Diederich 2y ago
Thanks for the clarification. I dug around for numbers but didn't look in the most obvious place! And yes, the cost difference is absolutely staggering.

Falcon Heavy, fully expendable, can send about 15,190kg to TLI (Trans Lunar Injection). The Saturn V sent about 48,600kg to TLI. The current SLS can send about 27,000kg to TLI, and block 2 is expected to send between 43,000kg and 47,000kg

Honestly most of the code I saw inside of Facebook was pretty solid, and some of it was exceptional.

I rode by their office in SF daily in 2015-2018 and even back then it was pretty rough. I've heard things have gotten only more difficult since.

From the article: "This is not meant to disparage therapists, advocates, or grief counselors. Each person must find their own way to deal with the reality that we perceive: what works for one may not work for others."

> but is Ariane actually competitive with SpaceX I think you're correct, Ariane isn't "competitive" with SpaceX, but it is "competition", which is a minor but important point. I've been following SpaceX

For all of the various challenges, structural and political, that Ariane 6 has dealt with, I truly hope this is a flawless launch. Any kind of additional competition is worthwhile.

by Diederich 2y ago
Do you think there is a reason that some distros go through all of this additional trouble?

Yeah this morning I was thinking about what the astronauts must be thinking. I would ride the Atlas/Centaur stack, it's been exceedingly reliable. Starliner itself? Not quite yet, given its checkered history. Boeing brings up no

This is obvious but I don't see it discussed or mentioned that often, so far. Massively decreasing the per mass cost of delivering any kind of cargo has huge and complex implications. Massively decreasing the per mass cost of deliverin

From what was said at the scrub conference, with additional context, it was scrubbed only because of more strict rules regarding it being a manned mission. Normally they would have just recycled a valve and moved ahead with the launch. Ap
