Hammered website edition? What's the cost of sending a Crew Dragon up? $50 cool millions or something? Say they pack a full complement of 7 people and 2 of them are employees for safety, that's a cool $10 millions just in cost.

It's definitely a millionaire's kind of amusement, however the cost would be driven down if it became a regular thing. Honestly because of the very fast pace SpaceX have set, and assuming all goes well, then Crew Starship will make Crew Dragon obsolete not too many years after Crew Dragons start flying. Even with Falcon Heavy you could get a craft double Crew Dragon's size to GTO with the same 6000kg payload, the small 6-8 man capsule is kinda on it's way out I think. Everybody might not be flying Starship sized vehicles in 20 years, but I doubt also that capsules with separate cargo and service/propulsion modules will remain the norm, not when the technology that allows vehicles to be more easily recovered and refurbished continues to progress.

No, you follow the fundamentals. Its just the fundamentals differ when stock is at rest and when its moving. When its static, the fundamentals are down to earth. When its moving, the fundamentals are gauging the reason for the move and understanding its limits. There's no unlimited move, but there are bumps here and there.

If you really want to fight, short the SPCE right now. You'll be left in pain. The smart thing is to gauge the public understanding of the stock and find out where the limit is,not your own understanding. Stock moves like a herd, not an individual. Your own understanding matters less than the herd's understanding.

Also if you really want to short, you have to do it with intense pressure. TSLAQ did it by controlling the narrative by passing their conspiracy theory as fact to mainstream media. Then court in union press sites and government officials who have it out for Tesla, and you get a great short run. However once the public learns they've been tricked by short, the stock will move to $5000+ and any remaining short will be burned endlessly.

There's a difference between wanting rational valuations of these companies and betting against them. Nearly all the analysts are wrong about SPCE, and they have practically zero understanding of space so they miss the key differences between them and other spaceflight companies so their arguments are framed incorrectly from the start. They don't question the key differences between SpaceShipTwo and its competitors. They don't even blink at the fact that it's incapable of reaching much beyond the Kármán line so it is barely in space or that point to point travel that is 25 times more expensive than a flight on a Concorde jet.

This is likely the biggest episode of mass delusion the market has seen in a while and there's no end in sight.

What do you think would be the type of propulsion used for the future interplanetary cargo transport vehicle, barring super advanced technology like fusion and beyond?

Nuclear thermal engines definitely have the specific impulse to be able to power transports economically, but there is a wide concern about the use of fissile materials. This concern is even greater if the concept of lots of commercial trade vessels were introduced. Electronic thrusters have the specific impulse needed too, but they're limited in power options. Atomic is out due the the above reasons, and solar limits where the transport can go. The "next best option" is a hydrolox chemical engine, but the specific impulse is just low enough to where refueling is required for both legs of the journey which can impact the economics of the transport.

I think that hydrolox would be used unless something happens that allow for most governments to feel comfortable with lots of nuclear reactors flying about in space.

On and around Earth.
When the industry exists to mine and incorporate this shit off Earth, not enough people will care close enough to the source to actually put on significant pressure. There will probably still be non-nuclear launch and descent and general proximity regs for rocks and infrastructure, but for actually burning between locales NTR or better nuclear pulse are just so overwhelmingly beneficial compared to chemical that holding them back will be a non-starter.

Don't get me wrong, hydrogen is great, but the drawback is everything involved becomes XBAWKS FUCKHUEG. That cuts into cargo capabilities too. What the fuck are you gonna do? Dump stages and pick up a new one every time you have to land some cargo and get ready for your next destination?

The engine and pressure vessels are the only real sticking point, and the pressure vessels not because their size fundamentally prohibits their function, only because nobody has had a need or reason to build a pressure vessel that large before. I think an autogenously pressurized methaLOX version could be done using a cluster of F1-like or similarly powerful boosters. Electric turbopumps using soon-to-be-realized high density batteries and already existing high torque brushless motors could give you very powerful, very compact, and comparatively simple turbomachinery, powerpacks can be dumped as they're depleted and if they were say solid electrolyte glass/sodium cells there really wouldn't be any pollution from them.

It might even be reminiscent of the N-1, since if you're using clusters of smaller engines you might have to introduce slight widening into the base to squeeze in the necessary number of bells.

Let's all take a moment to remember the Jupiter Icy Moons Orbiter. Back in the early 2000s NASA wanted to send a nuclear powered space battleship to study Jupiter's icy moons. It was going to have a small fission reactor that made electricity with turbines providing 200 KW of electric power. That's more power than the ISS generates with its solar panels. This powered some big ion engines and a full scale ice penetrating radar. In addition because they had so much power available they could transmit data back to earth faster. Because it had so much delta V it could have explored Ganymeade, Callisto, Europa, and even other moons like Io when their orbit was favorable. Oh and it was gonna drop a lander on Europa. The main thing about it was they started developing a high power fission reactor to power the damn thing. A reactor outputting more power than the ISS would have had applications outside of a Europa mission. The whole project got cancelled when Bush wanted to return to the Moon. That went nowhere and leftovers from that program became the SLS we have today.

The problem with space nuclear reactors isn't weight, it's how you make some complex moving machinery that works without maintenance for decades. But really developing nuclear power and propulsion, is something NASA SHOULD do in the age of Starship. Developing new tech that's literally too hot for private companies to touch is a job for NASA.

kilopower's not the best approach, it just the cheapest one, which is why NASA was able to do it at all.

Anybody catch the Zubrin interview a day or two ago? Elon recently gave him a tour of Boca Chica.

Some highlights:

*Musk is more concerned at this point with building a *shipyard* than with StarShip. He expects Boca Chica to expand from ~300 workers to ~3,000 within a year.
*The expected cost of Starship in mass production is... $5 million. Let that sink in for a moment, and remember that this includes 6 Raptors (Zubrin expects it to be more like $20 million, but still...).
*The dramatic drop in costs allows Musk to simply *not care* about things that Zubrin or others care about, like optimizing the mass budget. Notably, rather than wait for a Mars-capable nuclear reactor to be developed, Musk plans to use existing solar panels. When Zubrin pointed out that the energy requirements just to run the Sabatier chemical reactor to refuel a single StarsShip for a return trip by the next launch window would require 5 or 6 football fields' worth of solar panels, Musk replied, "Then that's what we'll ship".
*Likewise, it doesn't matter if the first 3-4 StarShips don't reach orbit; at those prices, SpaceX will simply eat the cost, and make the necessary improvements to the design so that the next half dozen *will*.
*They didn't really talk about the moon much, but Zubrin spent a lot of time in the interview detailing why StarShip can't land on the moon (tl;dr it's too heavy and the moon is too soft, and the thrust needed to land will dig an uneven crater into the surface as it comes down).
*Zubrin still has concerns about the execution of future steps, but he doesn't seem nearly as down on Musk's colonization plans as he used to. I think the sheer magnitude of the drop in cost/labor/materials really made a lot of his disagreements vanish. Zubrin's always focused heavily on managing the mass budget of his concepts, on the safe assumption that mass directly correlated with cost. Break that, and the impossible no longer appears to be so.

If we assume then the unit cost is around that much, let's even call it 50 mil a piece, you could build 3000 of them for the cost of the ISS, I could have sworn I also saw a unit cost hovering around 300 mil, if we assume that then it's 500 modules, since 3 B330's is roughly equivalent to the ISS in habitable volume, 500 of them would be comparable to about 166 ISS's worth of stations.

>“With $5.3 billion spent as of July 2018, NASA expects Boeing to exhaust the contract’s current value by early 2019, nearly three years before the contract is supposed to end and without delivering a single core stage or the [exploration upper stage],” said Ridge Bowman, director of the NASA OIG.

>At the current rate, the report found that Boeing will spend at least $8.9 billion through 2021 — “double the amount initially planned — while delivery of the first core stage has slipped 2 ½ years from June 2017 to December 2019 and may slip further.”

>On a call with reporters last week, Boeing’s Space Launch System vice president and program manager, John Shannon, said the project is on track to deliver the first core stage for the rocket to Kennedy Space Center by the end of the year, where it will be integrated with the other components.

>But the report disputed that estimate, saying Boeing would need an infusion of $1.2 billion through a renegotiated NASA contract for it to meet its goal of delivering to the Cape in December 2019 and then holding a test flight in June 2020.

It's oldspace politics.
Politicians from both parties get oldspace companies to set up shop in their constituencies, they get lots of money so the politicians can go back to their constituents and say "look at how many jobs I created for you since you voted for me! Vote for me again!".
Vertical integration? Cost cutting? Fuck that shit, we're talking jobs! We're talking re-election!
Who gives a fuck if you're burning tax payer money? It's their cushy positions at stake.

As long as politicians are involved, you're stuck with these parasites. It's an age old game called politics.

The solution to NASA's issue would be really simple to fix, at least insofar as the problems are not hypercomplex. NASA is a subsidiary of the Federal Government, pass legislation that prohibits NASA from preferential treatment of contractors, prohibit them from no-bid contracting, prohibit them from paying out or giving bonuses unless deadlines are met and projects are completed according to their originally projected end dates. By cracking open the established Fed-backed monopolies of the Aerospace giants like Cockheed, Boing, Northcuck, etc you would allow competition and thus innovation to actually occur. Then fix NASA's budget at 10% of GDP as it was during the Apollo era, and limit the number of dedicated projects they can work on simultaneously to say, 3. If they want to do a moon shot, or a mars shot, or a venus shot, they can't also be working on ten other smaller projects, since a lack of monopoly will not allow for as much rampant profiteering and economic leeching, a limited project number will ideally create strong incentives to accomplish only that which is maximally valuable to NASA's mission statements, and thus will return the best for the taxpayer resources dedicated to them.

>"NASA is an investment in America's future. As explores, pioneers, and innovators, we boldly expand frontiers in air and space to inspire and serve America and to benefit the quality of life on Earth. In fulfilling its mission, NASA contributes to America's goals in: -- Economic Growth and Security."

If they aren't doing this, then something is wrong and any amount of money the taxpayer is spending on them is being misused.

from the same speech:
>Even now, a rocket moves toward Mars. It reminds us that the world will not be the same for our children, or even for ourselves m a short span of years. The next man to stand here will look out on a scene different from our own, because ours is a time of change-- rapid and fantastic change bearing the secrets of nature, multiplying the nations, placing in uncertain hands new weapons for mastery and destruction, shaking old values, and uprooting old ways.

>How incredible it is that in this fragile existence, we should hate and destroy one another. There are possibilities enough for all who will abandon mastery over others to pursue mastery over nature. There is world enough for all to seek their happiness in their own way.
>Our Nation's course is abundantly clear. We aspire to nothing that belongs to others. We seek no dominion over our fellow man. but man's dominion over tyranny and misery.
>But more is required. Men want to be a part of a common enterprise--a cause greater than themselves. Each of us must find a way to advance the purpose of the Nation, thus finding new purpose for ourselves. Without this, we shall become a nation of strangers.

> I do not believe that the Great Society is the ordered, changeless, and sterile battalion of the ants. It is the excitement of becoming--always becoming, trying, probing, falling, resting, and trying again--but always trying and always gaining.
>In each generation, with toil and tears, we have had to earn our heritage again.
>If we fail now, we shall have forgotten in abundance what we learned in hardship: that democracy rests on faith, that freedom asks more than it gives, and that the judgment of God is harshest on those who are most favored.

Godamn, where has this uniquely American spirit gone to in the past few decades? When American exceptionalism and drive was talked about openly and grandly by our politicians. Neither Clinton, nor Bush nor Obama nor Trump have ever produced such a rousing speech like that, nowadays they focus on matters that speak to the business and equality and wealth and civil justice but nothing that speaks to the soul, to the role of man in the universe and the future that this nation should forge for itself.

Not to get too political, but I blame post-9/11 America. It showed that the country can be weak. The following conflicts and actions done to suppress terrorism world-wide placed in the recent public memory of how morally questionable the government can be. Both of these probably made most people feel that America isn't necessarily a good country. It made them think that it's a harmful country world-wide without integrity and thus need 'corrections'. This fueled reactionary extremes on both the left and right, but both failing to see what the true American spirit meant.

You have no external enemy anymore and your two parties are canceling whatever the other one started so as to not give the other one something to point at and tell the voters "look, we made that happen, not the other party".
Post 9/11 is a red herring. It's a post cold war thing.

Thomas Jefferson wrote of this:
>The people can not be all, and always, well informed. The part which is wrong will be discontented in proportion to the importance of the facts they misconceive. If they remain quiet under such misconceptions it is a lethargy, the forerunner of death to the public liberty. We have had 13 states independant 11 years. There has been one rebellion. That comes to one rebellion in a century and a half for each state. What country ever existed a century and a half without a rebellion? And what country can preserve it's liberties if their rulers are not warned from time to time that their people preserve the spirit of resistance? Let them take arms. The remedy is to set them right as to facts, pardon and pacify them. What signify a few lives lost in a century or two? The tree of liberty must be refreshed from time to time with the blood of patriots and tyrants. It is it's natural manure.
