>>14624884
Tory should've started reusing rockets earlier. He used to say that it wasn't feasible for ULA because they don't have a high launch cadence and needed 10 flights for sensibility to be profitable. Even if that was the case, they could've taken that experience to build a better rocket. As Spacex did with block5, and starship.

On the other hand, considering that not long ago talking about SpaceX at Ariane was taboo and everything but the Tried And True Way of Our Ancestors was considered foolish, it's noteworthy how quickly they managed to change their mentality and start working on future projects compared to some companies that are still in denial about the whole thing.

>>14625496
Not engaging with the argument, classic sign you haven't got shit.

Lol I’m sure Apollo could’ve continued to Mars if they were smart, and even with post-Apollo budget cuts. The shuttle was $1 billion per launch and it flew 4 times a year for 30 years. And the ISS program was $150 billion or so. The Saturn V was about $1 billion per launch too.
I’m sure NASA could’ve built a lunar base and did a Mars flyby in the 70’s, and used the support to do a manned mars landing in the 80’s. Idk.

>>14625498
Oh yeah LBJ was totally on the level about the Gulf of Tonkin lmao

Yeah. Pure power

>>14625592
converting stuff in metric follows the power of the unit, too.

A cubic kilometer is 1 km^3. A kilometer is 1000 meters. To convert 1 km^3 to m^3, you need to multiply by 1000^3, or one billion. This is because the meter and kilometer are units of length, not volume.

>>14625615
Why are you saying that the Russians and/or their government is communist? No deflecting, just answer.

The Navy figured out a long time ago that if you want a ship or submarine built, you convince some senator to sponsor it by naming it after their state. Why hasn't Elon also figured this out? It'd probably help to get them off his back, especially if he promised to source parts from the state on the RFP.

>>14625503
It was actually the NSA fucking up the intel reports. There's a phone transcript between LBJ and McNamara where they're just as confused over the report as everyone else.

He's managed to delude himself into thinking that his carnival ride is a legitimate space endeavor, and he was never willing to do the necessary deep-dive into aerospace principles and engineering that's necessary to give BO legitimate leadership and direction.

https://www.gao.gov/assets/gao-22-105212.pdf

>Continuing a recent trend, NASA's portfolio of major projects experienced significant cost and schedule overruns and more projects were added (see figure). Of the 21 major projects in the development phase of NASA's acquisition process (which includes building and launching the system), 15 were responsible for cumulative cost overruns of about $12 billion and cumulative schedule delays of 28 years. But just three projects--the James Webb Space Telescope, Space Launch System, and Orion--are responsible for more than three-quarters of the cost growth and almost half of the delays.

Fuck yeah

>>14625895
China has four functional launch sites: Jiuquan, Taiyuan, Xichang, and Wenchang. Comparisons aren't exact, but Jiuquan could be seen as being the most Baikonur-like. It started out as a ICBM test site, it's deep inland where its hard to spy on, they made their first manned launches from there, and the fact that it's in hick inner Mongolia severely limits its future prospects. Wenchang is closer to Cape Canaveral in that its coastal, nicely modernized, and all the interesting things in the future are planned to happen there. Taiyuan and Xichang are kinda like Wallops or Kodiak in that most people outside the enthusiast community tend to forget that they exist.

Will new Armstrong ever exist?

>>14625924

>>14625947
What do you have against Firefly specifically?

I did some math and I found an idea for a posts-Apollo SSTO derived from the Saturn V S-II stage:

S-II’s dry mass without engines is 27.3 tons.
The vehicle uses 3 Space Shuttle main engines (3.2 tons each). Let’s also say we use the Space Shuttle SRB parachute system - 3.9 tons.
Our vehicle uses three Falcon 9 style landing legs - 0.6 tons each.
Lastly, the heatshield. The shuttle’s heatshield had an area of 1,100 meters squared and a mass of 8.4 tons total. The 10 meter wide cylinder of the S-II SSTO has a base area of 75 meters squared, so even rounding up to 100 meters, it means our heatshield is a tenth of the shuttle’s. But we can round it up to 1 ton.

Putting it all together, we have a vehicle with a dry mass of 43.7 tons. We can round it up to 45 tons because of mass growth. The S-II stage held 443 tons of propellant, so there is a gross mass of 498 tons here.
The three SSMEs produce 558 tons of thrust at an isp of 452 seconds in a vacuum. That gives us a TWR of about 1.1 at liftoff. Slow but whatever.

A 10 ton payload (about the size of a soyuz) would give the vehicle a total dry mass of 55 tons and wet of 498. And a Delta V of 9.75 km/s. ENOUGH TO GET TO ORBIT! The S-II SSTO can drop off the cargo in LEO then deorbit.

This started off as a thought experiment but it is surprisingly doable I guess. The shuttle SRB parachute system landed the 90 ton dry SRBs at 23 m/s. I think it can land a 45 ton stage at 10-11 m/s no problem. Even then, solid retrorockets could be used to slow the stage down a bit as it lands.

One problem is the heatshield. I assume the existing S-II engine mounts are used for the SSMEs, although 2 are plugged up (only 3 engines). How do you fire an engine through a heatshield? Maybe put holes in the heatshield where the engines are, and use regenerative cooling during entry to keep the engines from melting.

>>14626071
A lot of SSTO designs from the 60’s and onwards featured a fuckhuge aerospike at the base being used as the heatshield because…I guess it works? No idea if it works on bell nozzles but aerospikes seem doable.

>>14626027
For heating reasons you can't use a base-only heat shield, it'd have to be a side heat shield like Starship.

>>14626099
checked
the idea was to run cryogens through the thicc base to cool it during reentry

>>14626099
>A lot of SSTO designs from the 60’s and onwards featured a fuckhuge aerospike at the base being used as the heatshield because…I guess it works?
Just because it was considered by engineers in the 60's doesn't mean it made sense or was even possible. A lot of these concept vehicles relied on materials with temperature tolerances way higher than anything that ended up being developed in real life.

why? got ditched for LV0013+ or moving to rocket 4 already?

>>14626234
Rocket 4. TROPICS will not fly at all this year.

>>14626234
New upper stage is the same diameter as the first stage unless I read >>14625892 incorrectly

>>14626238
damn, that's brutal if true. So all launches on rocket 3 are just on ice until rocket 4 gets made? Not sure how far along rocket 4 is in manufacturing/testing but that sounds like at least a year of delay for launch.

>>14625810
They were perfectly fine with Lockheed Martin and Boeing merging to form ULA.

>>14626256
They're worried about a monopoly that cuts out the backdoor funding funnel that sends money into their special bank accounts

>>14626251
>So all launches on rocket 3 are just on ice until rocket 4 gets made?
Yes.
>Not sure how far along rocket 4 is in manufacturing/testing but that sounds like at least a year of delay for launch.
That is my understanding as well. The good news is that LV0013 and LV0014 were always intended to be the last Rocket 3s made so this impacts at most four launches.

>>14626269
Rip Astrabro. I don’t think you’re company is going to make it.

>>14626278
If Astra were a pure launch company you'd be right and I'd already be responding to recruiters on Linkedin. Instead we've obtained a new factory for mass producing ion drives and will be able to use that and cash on hand to survive until Rocket 4. If Rocket 4's upper stage doesn't work more reliably, THEN we're fucked.

>>14626285
QRD on rocket 4? It uses two Reavers on the first stage but what changes on the second?
And why no announcement on Rocket 3 retiring?

Anyone else find it a little weird that Relativity supposedly has a full-stack rocket at the Cape, ready to launch at the end of the month, yet we've not seen any pictures of it?

>>14626285
>mass producing ion drives
Is the mercury propellant included?

>>14626298
>QRD on rocket 4?
It's bigger. One container per stage, integrated on site.
>It uses two Reavers on the first stage
We call them something different but yeah. Reaver is a Firefly (TV show) reference. Having seen the business end of a Rocket 3 first stage with all the ITAR bits exposed, the reduction from five to two engines is going to save a LOT of dry mass.
>but what changes on the second?
Still in flux but generally positive. See >>14625892

>>14626311
Yeah that's weird as fuck.

>>14626322
Why did TROPICS fail? The stage did fine for 3 minutes then shit itself

>>14626342
The investigation is still ongoing. I will say that LV0007 and LV0009 both ran out of fuel a bit early so it may be related.

Despite the shuttles many flaws, I can't help but miss the orbiter. It was such an incredibly cool aircraft.

>>14626488
No they just that starship wasn’t done yet. This was back in 2018 when Starship was still carbon fiber and
1) no test articles had been made yet
2) A full scale Raptor had yet to hit the test stand (the 2016 one was 1/3 scale)

>>14626298
>And why no announcement on Rocket 3 retiring?
Not astranon, but Rocket 4 is at least several months away (officially Q4 2022 debut). That could anger investors that care about quarterly results, even if it leads to fewer failures.

>>14626298
>>14626507

I wonder if that will be the first practical application of what they learn at ITER

>>14626558
>As we bring the price down more and more markets for something like this are going to open up," Langtry said. "We'll start with a million dollars per kilowatt, I guess, because that's where commercial solar appears to be. Once we get down to $100,000 per kilowatt, there's probably more applications that open up there; aviation is an interesting one, drones, whatever. And then as you get down to $10,000 or $3,000 per kilowatt you start to become competitive with other forms of terrestrial energy, like fuel cells and batteries and stuff.

so I've wondered for a long time...why did gemini use Titan II instead of Atlas Centaur? It should have had the capacity, so I've been surprised that I can't find mention of it being considered at all.

>>14626681
Oh, please no. Imagine if space CEOs were to become billionaires and known to normies, hell itself
>Peter Beck should pay his taxes!
>Tom Markusic is not an engineer
>Tim Ellis just steals his workers' credit!1!
>Tory Bruno is a snake (stays the same)

>>14626720
these are sick people, very sick people

>>14626736
No idea honestly. Atlas Centaur and Titan II started flying in 1962 - same year. Maybe the cryogenic upper stage on Centaur was too risky?

>>14626696
They will if he becomes the first person executed for destroying national security payloads.

>>14626751
The early Centaur success rate was pretty horrible. They didn't manage to start getting consecutive successes until 1966, and all of the failures through 1964 were directly related to some part of the Centaur stage.

>>14626736
>>14626751
it's pretty much that. centaur had several early failures and they knew titan II was a fairly low-risk upgrade from titan I. using the air force's rocket ended up causing a lot of political headaches for nasa because USAF got access to fly their own gemini missions as part of the deal (which eventually turned into MOL). if nasa had the chance to do it over again i think there's a good chance they go with atlas-centaur instead.

>>14626767
It's actually kind of ridiculous that the RL10 and Centaur got so close to hydrolox theoretical maximum performance in the 60s.

>>14626776
I mean, isp is isp, they knew what it was the minute they picked the fuel

>>14626776
a lot of vacuum isp is just a matter of nozzle expansion ratios. they could have gone higher but there were more pressing things to optimize.

>>14625233
because it means the ship survives for more than 180 seconds

>>14626776
The RS25 on the shuttle was legitimately the best engine ever made with regards to performance and thrust. And it came out in the 70’s

>>14626676

spacex wants to produce fuel on mars but fuel ships on earth still deliver to gas producing regions. so we'll probably see giant ass space tankers soon.

>>14626805
>452s Isp
>1.86MN thrust at sea level, more in vacuum

>>14626826
Now consider the dry mass of the engine and that of the vehicles that are needed to run it.

>>14626817
Ships don't need to carry 90%+ of their mass in fuel just to cross the ocean whereas landing 100t on Mars with Starship requires approximately 50,000t of propellant, assuming ten launches are needed to refuel.

>>14626840

>>14626903
Sometime after a well-established colony on Mars. Many of the relevant techniques will be explored on Phobos and Deimos, and Mars's position in the solar system just makes it easier.
Not much of a business case for it before that, though the Lunar Industrial Federation may have some interest in capturing NEOs if the moon actually turns out to lack critical volatiles and carbon (which I doubt).

It's unironically easier to build a rocket in real life and fly it than simulating it on a computer.
https://youtu.be/vYA0f6R5KAI

>>14626945
Hell no it isn't. It's harder to accurately model the physics in rocketry rather than having nature do its thing
I'd say playing KSP is far less taxing than actually flying something even to orbit, let alone other planets

>>14626963
Winging it and building a crude rocket engine from plumbing bits and a blowtorch is easier than is to learn how to use a real fluid simulation software (and arguably cheaper, given the cost of the simulation software I've seen)
I don't think anyone could argue achieving the same things in videogame is harder than doing them in real life

>>14626811
lmao, that is devious.

Expendable Starship/Superheavy will at first launch starlinks. Then superheavy reuse once they land reliably. While soacex continues to iterate on starship until it too can land reliably. All while spamming starlinks cheaper than Falcon o launches, and putting HLS into orbit.

Meanwhile ULA and NASA will be ask Jeff for their engines and flying that fat pig that is SLS.

>>14627003
People are saying they’ll try to reuse B7, and if not, very soon after. We might not see a booster splashdown.
The retards on NSF are adamant that there are changes to STarship OFT-1’s flight plan. We might see S24 go to full orbit instead of the express-trip-to-Hawaii

>>14627009
Reusing B7 doesn't make sense. They have never flown a booster and there are too many unknown factors regarding its reliability. If it had legs then I could argue that they might want to try and land it but for now splashdown is the only way.
Meanwhile, full orbit is a very probable scenario if they want to launch Starlinks on the first flight.

Booster 7 wont even static fire, let alone fly

>>14627067
You'll eat those words in three days

>>14626863
Indeed, but all of a sudden we're really noticing that lack of fuel energy density, which makes the on paper stats of the RS-25 a hell of a lot less impressive—and that only gets worse when you remember how massive the engine is for its thrust.

>>14626903
Moon will developed first, starting in the next couple decades, then likely NEAs as well in the latter half of this century.
Main belt will be next century most likely.
IMO the Mars colony will be somewhat instrumental to developing the main belt, ships built on Mars or Deimos/Phobos can get there a lot easier than from earth or even the moon.

I think the main value of Mars is that it has resources that make it a good place to sustain human life, at least compared to asteroids or the moon. So it can be an outpost for any super complex manufacturing that requires humans in the loop, whilst also having much lower orbital costs than earth.

The fact SLS uses SSMEs while not needing their extreme complexity due to reusability (compared to Energia's similiarly performing, much much cheaper RD-0120s) is probably the most laughable thing about all "Shuttle-derived" launcher proposals and ultimately SLS
