#742Earlier quoted context omitted.
Seems like it adds a lot of risk I'm actually wondering about that. If I understand correctly, the arms can move up and down, and pivot around the tower. This allows them to correct for some error in the rocket trajectory and also (presumably) "soften" the final contact. Between the nozzles and the arms, it gives SpaceX a lot of degrees of freedom in the final seconds (you can see how the booster kind of "hovered" ri…
It helps enormously that unlike Falcon-9 this rocket can dial down the thrust of its engines low enough to be able to actually hover or to move arbitrarily slowly in the final meters before touchdown. It can arrive to the designated intermediate point with some already good accuracy, and then take some time to trim the remaining errors to the noise level more slowly, possibly with feedback from the ground sensors. Th…
The main takeaway from Scott's commentary is that the chopsticks allow the ommission of landing legs and all their subsequent systems and saves a ton of weight. The added risk to dial this technique in is likely worth it in the long run from a sustainability stand point.

>The heatshield held out for a much longer time, the asymmetric heating on the flaps was interesting. I had guessed that all four flaps would have equivalent heating based on an approach that was basically that side of the rocket perpendicular to the flow but it seems like that isn't the case. Still it seems like they are close to having something workable here. Heat shielding didn't look relevant at this section of…
They're talking here about Starship, not the booster.
How does this logically make sense? They said "it looks like the heat shield held out".
Where was a heat shield holding out?

#744Amazing days ahead of us - if we can avoid blowing ourselves up over pathetic patches of land, we could have the entire solar system under our feet...
> pathetic patches of land
It's always funny seeing people pretend they live in a world where small issues like land or food don't affect them, even though they only have that privilege because a larger military says they should.

#745I don’t understand, the starship has to stand on something, and what ever that is in contact with ( arm or barge or land or whatever ) , needs to be as heavy, how they are saving weight ?
Re: Starship Flight 5: Launch and booster catch [video]
#746Pretty impressive. The engineering team at SpaceX is really something. Some thoughts; The 'chopsticks catch' was amazing to watch. Seems like it adds a lot of risk and clearly the booster needs additional fire suppression systems :-) perhaps the tower could mount something that sprays the booster like the barges have for the F9 boosters. The heatshield held out for a much longer time, the asymmetric heating on the fl…

There's no reason to reinvent the airport firetruck.

#747Nothing could have prepared me for how that catch looked. I was sure the rocket was careening into the tower at the last second before it straightened out. The control algorithms must be incredible for the landing system to work within those small tolerances.
That was one of the greatest things I've ever seen.
Can you explain why? I don't understand why this is so important

#748Unbelievable. Amazing.
Re: Starship Flight 5: Launch and booster catch [video]
#749Strategically this is huge for the US and NATO. Being able to put orders of magnitude more payload in orbit at a fraction of the cost of the competition is a huge advantage in controlling space. Starlink and starshield are already years ahead of what china and russia has, starship is going to widen that gap even further.
The most expensive part is to support the risk and cost of research & development. Sure, that renders you the first place for a while, but expect others to move easier (and thus faster) after you marked the trail.

If elon can do everything he’s done with an increasingly hostile govt, imagine what he’ll be able to so with a supportive one
It's a joke to think trump cares about taking care of his own after all the evidence to the contrary. He throws everyone under the bus the first chance the gets.
> When Elon Musk came to the White House asking me for help on all of his many subsidized projects, whether it's electric cars that don't drive long enough, driverless cars that crash, or rocketships to nowhere, without which subsidies he'd be worthless and tell me how he was a big Trump fan and Republican, I could have said, "drop to your knees and beg," and he would have done it,"
