They talk about how satellite constellations can connect and observe the whole world, they'll have many applications, like world wide internet or tracking whale migrations, and some things we can't even think of yet. So they're building a rocket that is convenient and can launch anywhere. They achieved great reliability with their small rocket and now they're ready to go bigger. At the end he says Japan has to be ready by 2030 if it wants a place in the market, after that it's too late.

That's not an unreasonable position. Even Europe's come around to the idea that they need some kind of reusable launch vehicle (although Arianespace is insisting that they be the ones to build it and operate it as a monopoly). Starship, etc, aren't going to kill off the old expendable launchers but they are going to make the groups that rely on expendable launchers hopelessly second class when it comes to space infrastructure.

simp for the cetaceans all you like, the whales are going extinct anyway if nothing is done about global warming. eating a few whales saves the rest of them from dying of starvation due to overpopulation, whales are like lemmings, they'll eat all the food in their environment and then starve to death if left unmanaged, only difference is whales have nowhere to run away to once it happens.

That's geographic return for you.

If you remove the Side boosters you remove a good part of Italy's 15% budget contribution (which is mandated by law to have a return on local industrial investment equivalent to its contribution) to A5 and a smaller part of France's 45% contribution, let alone the smaller belgian, austrian, german contribution to the EAP the whole industrial process just collapses like a house of card and you can be sure there won't be any Ariane 6! .

And it goes deeper on the subnational level, because now you hurt Lazio's and Brussel's aerospace industry a lot, the Europropulsion joint-venture between Safran and Fiat collapses, the Safran Herakles factory in Aquitaine is now underused which vastly increases the cost of France's M51 ICBMs, the French guyana Propellant Factory is now useless and you've removed a significant part of the Guyana Space Center's employment which is the economic center of the whole region of French Guyana (which sends 2 Member of Parliament and 2 senators to the French Parliament)...

>During his second day on the witness stand, Musk claimed that another reason he said he had “funding secured” for a deal back in 2018 was that he could have sold shares of SpaceX, a U.S. defense contractor and satellite internet company that he also runs, in order to finance the transaction.
>Musk said under oath, “SpaceX stock alone meant ‘funding secured’ by itself. It’s not that I want to sell SpaceX stock but I could have, and if you look at the Twitter transaction — that is what I did. I sold Tesla stock to complete the Twitter transaction. And I would have done the same here.”

So far China has yet to do achieve heavy lift and their solution to get that done is changing the design from 11m to 10.6 and back every year to allow for as little to get done as possible.

I'm not saying the Chinese can't do it, because at least to me it seems that they're trying, but this is a rocket far more complicated than the 5b and they're trying to hit a very difficult moving target.

Technically its bullshit. But the matter ultimately is of intent and delivery, and given how he actually went through with the Tesla sale to fund Twitter, and given that he owns 48% of all outstanding SpaceX shares that exist, there's enough wiggle room to influence the jury to his side. Had he not done what he did with Tesla shares to acquire Twitter, the way this case would play out would be much different.

Not on this launch. They do it relatively (too) rarely which, imo, slows the reuse program.

They should aggressively pursue the reuse of Electron to lower the cost of launch and attract investor money. All lessons learned from reusing Electron will also help with Neutron as they can pinpoint which elements tend to break first, practice post-flight inspections and develop best-practices. That's my biggest complain about Beck as I think that otherwise he is doing a fantastic job.

It's a lot harder to take chances testing a reuse system when each test requires you to put human crew in harms way. SpaceX would have taken a lot longer to nail droneship recovery if the droneships all had crew on board.

There's also the problem that Electron can't get enough customers to fill out its current flight rate, let alone a faster reusable one.

Reasons to make your own Starship clone:

1. Builds a large population of home grown aerospace talent
2. Creates an industry ripe for disruption or creates an industry that otherwise did not exist
3. Aerospace tech has an inverse square positive feedback on the rest of the market in which it excels in
4. Because having your own launch capability is good
5. Because having your own engines and reusable orbital class capabilities is good
6. Because having a strong aerospace sector is the path towards all kinds of technological, material science, computing, and biotech breakthroughs that otherwise would not be pursued
7. Because having a strong aerospace sector also forces transition of economies and cultural towards a more sustainable direction

Serious question - but vague. It deserves a serious followup question -
- Are you talking about a moon like in one of Neil Comins' books around an alien starsystem's planet, in the HZ? or are you talking about Earth colonies on Callisto and Titan?
Comins' model seems difficult to work in practice. A habitable moon might form around a superJovian at 1 AU from a G dwarf (like ours). But I'd worry that superJovian would irradiate that moon.
For us here around Sol, the Jovians are a tough call. Jupiter's radiation starts getting ugly around Ganymede although Ganymede might be able to resist it once we've landed.

It sounds good, and it doesn't work. However that's not why they're a scam. Helion is a scam because they are lying in a very obvious way to any expert.
The fusion cross section of He3-D is far smaller than the D-D fusion cross section. Even a 95% He3 5% D gas mixture is going to preferentially fuse deuterium and make plenty of nice little neutrons. They lie about this in their video. They also talk about He3 producing more power because each reaction releases more energy than a D-T fusion reaction, which is a lie by omission of the fact that He-3 fusion occurs far slower than D-D fusion at any given triple product condition.

>Same as last response about the rise of prices
As prices rise due to scarcity, less-rich lithium deposits become economical to exploit. Since the frequency of lithium deposits increases greatly the lower the concentration you look at, this effectively means we will "never" run out of lithium, because at some point the cost of pulling lithium out of sea water will become lower than the market value of that lithium. Of course, with modern energy prices that lithium would be very expensive vs modern lithium, but then again, as improvements in technology continue to drop the price of energy, this will also bring down the cost of lithium extraction from any source.

Also, as lithium prices rise, there will be greater and greater incentive to develop sodium ion batteries as a replacement for non-mobile energy storage (ie, grid battery banks). Sodium is hyperabundant, so assuming we have an easily mass-manufacturable rechargeable design with good cycle life, sodium ion batteries would out compete lithium batteries in those huge multi-megawatt storage arrays that grids will be buying.

Did you really think they never considered a chute?
Chutes have very poor accuracy, did you notice they stopped trying to use chutes for fairing recovery? You really don't want your rocket engines in the ocean because salt water, and there's no way you're going to land it upright on a pad with a chute.
Also the engines are already there, so no extra weight needed, and there needs to be some fuel margin for a successful launch anyhow. The amount of fuel needed for a powered landing of an empty rocket is a fraction of what it needed going up.

$10 mil is becoming pretty standard for any engine made these days (SSME bullshit aside), although I hope that one day soon even this will be considered way too expensive. If raptor can be made for like, what, $2-4 mil or even lower, then there’s no reason why a BE-4 or an AR1 or an RL-10 or any other engine shouldn’t have a production cost of $1 million USD or less.

Pretty crazy how much you save by making your own engine. Imagine if SX had to buy RL-10s for its upper stage.

>Actually, ISRO had an early start when V.R. Gowariker proposed the Cryogenic Technique Project in 1970. By mid-1971, a team had been formed to define a road map and to undertake the development. Starting with a pressure-fed semi-cryogenic engine of 5 kN thrust, the programme envisaged the development of a 680 kN pump fed LOX-LH2 engine for booster applications. Against all odds, a semi-cryogenic pressure-fed engine was tested for a few seconds before the end of 1971. The preliminary design for a 75 kN LOX-LH2 engine was completed. The shower head injector elements of a 30 kN LOX-kerosene engine was also tested at the then National Aeronautical Laboratory. The programme was however aborted with the demise of Sarabhai.

Not really no. The thing about diffuse sources like nebulae is that being closer doesn't actually help. As you get closer the light collected by the eye increases, but it also becomes bigger in angle ans so the light is spread over more of the retina. The surface brightness of the nebula is constant. It would become easier to see because it's easier to notice big faint objects than little ones, but it would never look like these pictures.

The vent might have been a "nominal" safety feature, although that can be debatable too, but was not a "per-the-nominal-timeline" event. Likewise, there is information now trickling that there are certain items to iron out, and another post-static-firing WDR is very much foreseen, provided the firing happens without a hitch, which is a very big 'if' by itself. Apart from that, people are pointing out how large gushes of liquid were seen pouring out, whose visibility has little to do with local humidity conditions.

Also, the WDR can be qualified as successful based on public info, but we know for a fact several issues which were not so visibly obvious will need to be adressed before launch (details in L1+1), leading to the foreseeable WDR#2 - so certainly the WDR was not "nominal" in the true sense of the word: not any more than SLS' "leaky" WDRs, obviously for different reasons. As usual in this project, any noting of inadequacies is quickly brushed aside as doomerism
