The military propaganda at 9:30 was interesting. Showing Chinese people while saying "our adversaries". Has it ever been done so overtly before ?
Good. Call China what it is.

#133I'm kind of surprised a random SpaceX launch is #1 on HN, when on the same day, China just completed their modular space station: https://news.ycombinator.com/item?id=33422779
This is a launch of falcon heavy, there's only been a handful (unlike single falcon 9, which are more common and might be the "random SpaceX launch" you had in mind). It's also a live stream instead of a news article.
But other space news events are interesting too of course

Falcon9 launched Starlink, without which the course of the Ukraine war might have been significantly different. There's also the plan to pull CO2 from the atmosphere to create rocket fuel. https://labusinessjournal.com/manufacturing/aerospace/big-pl... There's the Dragon 2, the only US human space vehicle in operation, as the Space Shuttle has been retired in 2011 due to expenses and safety issues. https://en.wikiped…

I will bite. Why won't the laws of physics and chemistry allow it?
Re: Falcon Heavy Launch [video]
#135Possibly the most expensive thing in the world with a publicly listed price ($97M) and sales contact (sales@spacex.com)? https://www.spacex.com/media/Capabilities&Services.pdf Just find that amusingly 'accessible'.
Yes but I think it’s due to competition even ISRO has their price list on the net
Re: Falcon Heavy Launch [video]
#136Now that Falcon 9 landings have become so routine, it feels surprisingly wasteful to see that mission profile with the center booster burning up without even trying. I wanted to write something about that lack of center booster reuse on falcon heavy feeling irrationally worse than a single F9 launch in the non-reusable profile (for a slightly higher payload iirc), but then I discovered that the non-reusable F9 profil…
When you are watching SpaceX launch videos, pay attention to the velocities at which the various engine burns begin and end. Reaching higher velocities (for comparable payloads, etc.) requires burning more fuel - so there is less fuel left in the tank to perform boost-back burns, entry burns, and landing burns. Not enough fuel for a boost-back burn (the typical situation) means "barge landing". Not enough fuel for an…
And this customer asked for no filming later in the launch. So they are rich and secretive - I wonder who that could be?

It's indeed kinda refreshing to see a company actually put such a high pricetag out there... and all the more frustrating that so many companies demand contact info for a "quote" when I don't need to do that to launch something into outer fucking space .
Of course nobody actually pays that.
>Of course nobody actually pays that
That's not the point.
Re: Falcon Heavy Launch [video]
#138Seeing those boosters land will never get old. I drive by one on my way to work every day and it's just amazing how large they are.
And for some reason seeing 2 land at the same time is a 100 times cooler. Seems like coolness is non-linear.
I don't think you can extrapolate whether it's linear from two datapoints.

Or ... "max waste" ... no harm being honest about it and keeing peoples eyes on the prize!
"Max waste" would be all three boosters not surviving. One booster being expended is more like "min waste" (besides losing none, obviously)
"max waste" would be all 3 boosters exploding on the pad with the engineering team swarming around them. Nedelin style.

I think, to some degree, this is because we got used to seeing one landing.
It's hard to measure objectively but I feel I was dramatically more impressed seeing first Falcon Heavy come down than I was seeing the first successful (non-heavy) landing. I've shown a lot of people (who aren't otherwise into space) the original Falcon Heavy landing video: https://www.youtube.com/watch?v=wbSwFU6tY1c
The most common response, by far, is: "Is that real?"
It really is just that amazing. Even look at the YouTube comments. It's enough to make even the internet become a place of shared awe, wonder, and inspiration. Makes one wonder what the world would be like if we had media that focused more on things like this and less on things that divide and agitate people.
