The first stage of the Falcon 9 does not go to Orbit. These test flights might be low altitude but the flip and landing is realistic.

I do not believe the $2 million for Merlin. That number was der At peak production rate Merlin was less then $2 million, I think $1 million or maybe less be now. Or maybe a little more again since production rates have likely declined a bit

So a single failure of a prototype means its never ever ever gone work? What kind of logic is that? Also you are wrong. SN9 actually used 2 engines for the flip, not 3. They only swapped to 3 for SN10 and the flipped worked perfectly there.

Let me do some guesses. Well, they are shooting at a per Raptor cost of 100k long term 250k short term. Even assuming it is 4x as much now, that is about 3m for the engines. The stainless steel only cost a couple 100k$ at most. Add in some

The flip starts with 3 engines and should work even if 1 of them doesn't start.

In theory yes, and if worse comes to worse that is an option. But its not what any rocket designer would want to do. Having a mechanical system inside of a deep cryo liquid methane is hugely complex and very heavy. Even if you put it outsid

I think its a bit early to say its not viable. Header tanks are there precisely to solve this. The sloshing in the header tanks should manageable in a tank sized correctly, specially if you are willing add some extra baffling to the header

The US was certainty concerned about Soviet reaction and a potential nuclear reaction had the US attempted to invade Northern Vietnam.

There are so many issues with simply saying 'workers should own 51% of the company'. That statement and causes so many issues in every aspect of how companies are now run an financed, its hard to even imagine what such a regulatio

> Nuclear energy without subsidies is not sustainable at all. This is nonsense. We are basically using 60s technology that has some of these problems. A modern reactor facility could be 10-50x smaller for the same output and that makes t

Yes, this. I am a huge fan of thorium breeders and there are few other minor advantages but people have gone of the deep end. If you are not doing a breeder, uranium is just fine.

I still don't understand why nuclear waste needs long terms storage. With Burner reactors you can produce waste that only needs storage for 100s of years, not 1000s. Its easy to store and manage, basically it can just stand in a field,

There are many ways to do recycling and we have 100s of years to figure it out. What we do now is doable, but its the worst possible thing. Other forms of recycling are very viable and have much less problems and much less side streams. The

Sure, if you engage in strategically idiotic wars in places where there is tacit agreement with the other super power that it is ok, that might happen. But it was not actually relevant. The reason the US never invaded the North was because

And the major reason for it is that no program as expensive as the F-35 has been done to attempt to develop such a thing. Or rather multiple different drones depending on what thing you actually wanted to do.

Yeah all those evil dictators who constantly want to attack super-powerful much bigger countries. Just incredible how often that happens. I mean super-powers with nuclear weapons just constantly have to fight of these dictators. What an odd

Unfortunately the military is the most trusted institution in the US. Why I don't understand? People will scream about reducing military spending but scream about increase in other things. Its funny however since most people in the US

Another service update, nuclear weapons exist. Any situation that involves high tech piloted planes fighting each other in the sky is almost impossible to happen. Dropping insane amounts of resources into piloted figher plane is bordering o

Secret launches are not really possible in the sense that you mean. There are 'secret' launches for the DoD but those usually get announced just a very short time before launch. So it might be a week or so before SpaceX will be li
