I wanna use a Cybertruck as a chassis for a superior robotic rover that drives stupid fast and collects way more science just to dab on NASA.

>>12471331
Your attitude would turn right around if you bought some Boeing stock.

>>12471316
I checked Astra's Twitter, and they actually deleted the "orbital space" tweet kek >>12470280
the article it was quoting is still up though https://techcrunch.com/2020/12/15/launch-startup-astras-rocket-reaches-space-for-the-first-time/

>>12471343
Just think, a cybertruck based moon buggy with an M2HB in the back is technically a mobile anti orbital weapons platform in lunar gravity.

>>12471348
No eta on when that could happen. Wonder if Elon will wait until he can put up 400 Starlinks a launch with Starship.

What's your take on the best bang for buck low tech terraforming method for Mars? Here is mine

>Use big mirrors/lenses to heat ice caps and bring the whole planet up to a reasonable temperature
>Forget trying to electrolyse water for oxygen/Hydrogen, not enough of it and a waste of water anyway
>Use giant fucking lense to btfo molten rock/regolith canals to release enough stored CO2 to bring it up to a passable atmospheric density

Yeah its not breathable but you can walk around without a suit, just an O2 bottle for minimal effort. I guess the next step would be seeing if there is enough ice asteroids that could be put on Mars intercept with minimal dV to give you a water cycle.

>>12471342

????????? what do you think shrimp are

>>12471647
You mean it's supposed to bounce off of the atmosphere a bunch of times?
Yeah ok I should have figured that. The cheaper grid fins in ksp always melted off on my ships as well.

>>12471649
crustaceans, not insects. they are both arthropods though

>>12471652
grid fins are more for steering
the starship has fat fully solid fins because it wants as much drag and surface area as possible going into the atmosphere to slow down

>>12471630
Sea bug good, land bug bad. Simple as.

>>12471638
lol his virgin galactic video made hoes mad. fucking hilarious considering virgin galactic has no business case. sure as shit doesnt close. it's not like theyre gonna carry cargo like a c17 or some shit. plus richard branson is a known bungler at best, at worst a fraudster.

Funny you should mention that, but when the stock market dropped back in march from the shutdown, I started buying up stock from lots of places.
Boeing stock went from $300+ to about $100 a share at the end of March. Its over $200 a share now.

SN10 nosecone getting flaps

>>12471638
I like it. But at the same time it's missing a kind of "x-factor" that really good channels have. Something to set it apart. But I'm sure he'll find it in due time. That's the kind of thing that you develop through experience, incremental improvement, and non-trivial expenditure.

With Trump gone, fears of Russia and white supremacy are the only things uniting the "bribed by China" and "remain independent" factions of our elite.

>>12471482
Fuck Ceres, still too big, too many potential colonists. We need a proper scattering. There will be no tyrannical government on a 2 Km wide rock where everybody knows everybody and everybody is more or less required for communal survival. And if one pop up, you just take your friends and family to the next one...

>>12472054
Why does that flap look so bumpy when SN9 flaps were so smooth?

>>12472127
for her pleasure

https://youtu.be/9BdDEVFrz3k

This is cool. Simulated telemetry for SN8. According to this the Raptors were indeed heavily throttled. In addition, SN8's terminal velocity was something around 70m/s, whereas Falcon 9's is around 260m/s before the landing burn. Some have put SN8's terminal velocity at a lower bound: https://imgur.com/a/a4n5H7v

version with commentary: https://youtu.be/XJZ7VWzqtJM


>>12472127
I think it's just the light. From what I remember flaps have always looked a bit bumpy.

>>12472144
>SN8's terminal velocity was something around 70m/s
Seems legit. Pic related was from Elon's 2019 Starship update. The numbers for the flip are also pretty close.

>>12472191
>pic
WTF? Texas let them do that to the ground?

>>12472144
good lord the F9 is a skinny beast.

>>12472195
derealityation is based

I'm still impressed at how huge the usable space is in Starship. Literally everything else is tiny in comparison or has all its space taken up by hydrolox tanks.

>>12472201
like this. Cramped as fuck.

>>12471368
>rotating annular aerospike
what

What does /sfg/ think about Maxar?

I'm not too interested in the imagery side of their business, although I see it growing as imagery constellations enable near constant surveillance of the earth's surface and it creates a lot of useful data to analyze and sell. I'm more interested on if they can take advantage of Starship greatly lowing launch prices and become a dominate smallsat manufacturer. I understand their GEO satellite business is struggling but that's a very competitive sector.

Retail investors in this space don't have a lot of options besides the old space companies. Maxar is more of a pure play but still pretty much old space. Beyond that as far as I know there's just Momentus Space, a bunch of communication satellite companies which I'm not interested in, and LMAO Virgin Galactic.

This is the only further info given. So Russia may have performed an unannounced space launch?

>>12472035
What a retarded thing to say without any more info.
That's some dramatic shit if it's LEO. There's been what 3 livefire tests in the entire history of ASAT?

>>12472221
Did anyone see the expanse earlier? One of the signs was advertising "cricket protein".

>>12472228
So they tested a missile but didn't actually shoot down anything? So the fuck what? Everyone has done this a bunch of times.

Looks like it was a Nudol missile test. It's used for both ASAT and missile defense roles.

>>12472220
only going by what i read on your post, i will assume that they make sats and are specializing in imagery which i usually connect with observation and telescopes

if they're smart they should develop astronomy sats or something to that direction

>>12472243

>how DARE anyone try and weaponize space to threaten our weaponization of space

>>12472201
Idiot here, why is there a fuel (or oxidiser, specifically) tank at the top of the fairing? Is that normal?

I always thought fuel tanks were at the bottom of the rocket

>>12472249
> Cone of shame
We've all been there

>>12472280
Header tank. Because when landing, the fuel in the main tanks is sloshing around and not where it can be drained down into the engine by piping. Header tanks are reserved for landing only.

>>12472256
I thinks she's cute but then again I'm barely civilised.

>>12472280
>>12472287
also they need it to keep the center of gravity higher during the flip
so it's not just fuel, it's also a counterweight

Thanks bros, I just started experimenting with going off script on the virgin galactic video. Hopefully with that I can start showing more personality. I'd honestly love to also start talking more about international affairs in space, stuff like the artemis accords and ASAT tests.

On my latest video, Some people are just delusional about virgin galactic. One guy in the comments is talking about investing in Virgin for ten plus years. I might actually do a series on "space" stocks like BA, LMT, and some more obscure ones like LHX and BWXT. Because the stock trading world is fucking retarded when it comes to space, it's why you see private investors funding shit like ARCA with it's green rocket lol.

>>12472374
SPCE is bullshit. Entire premise rests upon the idea that it sounds similar to SpaceX. I'm not even kidding. They must have heard about point to point transport from somewhere (spacex starship) and thought this is what SPCE is. Never mind the fact SpaceX is the only one talking about point2point and virgin is only talking about 4min joy ride to space.

People there are delusional.

>>12472144
> Simulated
Is the official telemetry encrypted? Would be easy enough to pick up with an sdr.

>>12472392
I'm certain that Virgin has brought up point2point before, except they wanted to be the luxury/business jet version instead of the economy class version that Starship would be.

>>12472392
Every NewSpace companies riding on the SpaceX's hype.

>>12472392
SPCE is Branson's tax dodge.

Suppose in the not so distant future space does get cheaper and there's sufficient commercial viability and interest for a burgeoning market, as is the hope. Suppose at least one starship launch a day, and growing.

What would be the limiting factor for growth? LOX production methods? surely it wouldn't be methane. Enough skilled people to maintain and manage so many rockets?

>>12472392
Yeah, it is, I took a pretty mild take and the like to dislike ratio is 60%. It's like a cult

I've been dealing with delusional SPCE bulls since it existed. If you're looking to get eyes on your channel, maybe do a video on AST as news just broke that it is going public and it has an approach to mobile satellite internet that is very different than the other companies getting into this sector. Maxar is another option because it's more of a pure-play than the other old space companies.

Noise complaints are also a factor. Rockets are loud, louder than passenger planes. Having a rocket launch every once a couple of weeks is bearable but every day? Every 12 hours?

If you want to launch rockets as frequent as passenger planes, the rockets would have to be launched from a place relatively far from peoples homes.

>>12472374
>>12472441
Also, Momentus Space is another topic that isn't well covered. Ticker is SRAC. This is my favorite space stock.

>>12472441
SPCE is the same as Nikola.
People thought it might be similar to an Elon Musk company and didn't want to miss out on the run on the, in their minds, predestined success.

>>12472441
Maybe you could talk about some of the parent company conglomerates or investment groups like Spacefund

>>12472474
when will people understand that there wont be another Tesla or SpaceX, another Musk. He's a once in alifetime character. We desperately need to secure his dna for cloning in the future

>>12472478
he has like 7 sons

>>12472474
Not quite as Nikola but close. Virgin has a vehicle they've been working hard genuinely for years. The whole SPCE is prob a clever choice from business point and probably wasn't any foul play from Brandon/virgin. It's just the investors are retard in this case. Nikola was a pure cash grab trying to pull string from Tesla's fame. Both investors and the company are fraudulently exploiting each other.

>>12472441
Yup, just saw it. Don't fully understand AST yet but I'll do some research.

>>12472455
Got it

>>12472483
>Virgin has a vehicle they've been working hard genuinely for years
with the sole ambition of sub-orbital space tourism

>>12472453
>Noise complaints are also a factor. Rockets are loud, louder than passenger planes. Having a rocket launch every once a couple of weeks is bearable but every day? Every 12 hours?

This is why point-to-point Starship will almost certainly never happen outside of select transoceanic routes. It's going to make Concorde sound as quiet as a Cessna by comparison.

What are the chances of MacKenzie Scott starting a spaceflight company to try and screw over her ex?

>>12472492

what's your point? do they have any ambitions? never heard of musks kids accomplishing anything. also it seems most of the women musk knocks up are dumb as rocks, maybe the kids got their mother's personalities. he's also a bit of an absent father, to put it lightly. doubt his kids give a shit about their dad's projects.

>>12472521
2021? Why do you want the rocket to launch in 2022? Don't you know that's too dangerous? Our highly skilled engineers need to carefully inspect every bolt before we even consider the 2024 launch. You should be proud that America is working on this most spectacular rocket that will launch in 2028.

Latest GAO report on sls out. Crew sls won't launch atleast until 2026 done by nasa's own study assessment. Cargo may launch in 2024.

Just to put some things into perspective, if Apollo was managed like how SLS is, then Apollo 4 would happen in 1971, Apollo 8 on 1980, and Apollo 11 on 1981 (most likely 1983).

Oldspace is a CIA conspiracy designed to make spaceflight look *hard* so that the next big milestone is always just a few years off and each generation is raised to wait 'just a little longer' before the great age of Space will begin.

This is just a part of the Plan to keeps us locked inside this terrible atmosphere (remove it) forever. Musk's soul is not tethered by gravity, so he's attempting to boldly escape this prison himself and take a few others with him before the bars are finished and the key thrown away.

>>12471674
>>12471693
Actually the issue back then was that the natural gas industry wasn't as developed as it is today. The only reason they went with kerosene was because it's basically the same stuff as aviation jet fuel, they simply put it through more purification steps to remove more sulfur.
Any other reason for using kerosene (muh density, muh easy to handle room temp liquid) is backwards justification. Kerosene rockets use cryogenic liquid oxygen oxidizer anyways, so using cryogenic methane as well is not actually a challenge. Cryogenic methalox gets less bulk density than kerolox, but is more efficient, meaning the overall performance of a methalox rocket is greater than a kerolox rocket even before you consider other technological pathways to improvement like better combustion cycles.

>>12473245
Fugg maybe Starship can SSTO with minimal cargo.
Definitely can go Suborbital by itself.

did they really believe that this thing would just roll out without any examinations and apparent flap replacement in one day

>>12471696
>they could have done winged boosters tho right?
Yup.
Using nothing but gas-generator engines similar to the ones already developed in the 60's, it's possible to design a fully reusable TSTO vehicle which uses gliding reentry to recover both the Booster vehicle and the Orbiter vehicle. In fact it's not really that difficult at all, as long as you don't get trapped making dicey material selection choices in order to increase payload mass.

Torch ignition is already a no brainer for a future reusable engine. Steel body, spark plugs, large cargo capacity... it's a space truck.

>>12473399
why don't more engines use torch ignition? Sounds like a no-brainer to me

>>12473421
It's a much more complicated system than using a hypergolic starting fluid.

>>12473421
>>12473426
Nobody else is building seriously reusable engines yet.

>>12473345
>we already know it can without headers, flaps, cargo, heat shielding. but then what's the point
taking out an enemy space station with a single launch?

>>12473421
Why bother when you use them once? Do firecrackers have reusable torch ignition built into them?

>>12473097
>...Or does this method of launching offer little advantage over traditional launches?
The advantage (singular) is that you can fly your launch pad to whatever latitude works best for your launch inclination. There's no significant delta V advantage.
The drawbacks are many, but the biggest is obviously that you can't design a bigger rocket than your air launch platform's maximum carrying mass. Even a Falcon 9 2nd stage masses close to 100 tons, so you can imagine that you're not gonna be able to get much payload per launch with a system like this.

>>12473450
Anon you can do that with an SM-3 off an Aegis cruiser if it's in LEO.

>>12473205
Correct, but our space agencies should react as if it is real anyway, just so that we end up stomping chine even harder.

>>12473382
we need to start thinking big

>>12473461
That's how the Cold War worked.

>>12473278
And production Starship will have twice the number of engines, with the addition of the three Raptor Vacs, which are also capable of firing in atmosphere.

>>12473458
You also don't have to scrub for weather, which is nice.

>>12473477
more fuel + more engines + heat shield + 150 tons cargo = heavier = slower

>>12473426
>It's a much more complicated system than using a hypergolic starting fluid
I dunno if it is. I think it's just that using pyrophoric fluid to start the engine guarantees that there's gonna be fire in the combustion chamber as long as the valves open correctly. Oldspace is terrified of taking any risks.

>>12473458
It also allows you to have launch facilities in places without a free east facing corridor. Places with west facing coastline can use it to hit prograde orbits.

>>12473452
>Soyuz rockets are still using big match sticks stuck up inside the engine for launch ignition
lmao
>>12473481
You do if there's weather at the runway, or at the launch zone. You can't just fly around until you find a place with clear skies and hit the launch button.

>>12473487
Yeah, obviously, except also no.
Adding engines and heat shield is more dry mass, which reduces delta V. BUT, being able to fill the tanks all the way massively increases delta V, because of the much bigger wet-dry mass ratio. Three Raptors can't lift off with full tanks; in fact even 6 Raptors probably won't make enough thrust to push a fully loaded Starship at >1g.
I'm not an advocate for Starship SSTO, but it's definitely within the realm of possibility for SpaceX if they wanted to build a no-TPS no-flaps no-headers one off version of Starship to perform an SSTO flight just to steal the milestone and prove once and for all that SSTO bows to TSTO in all aspects.

>>12473487

>Microsoft's dominance of the x86-based personal computer operating systems market constituted a monopoly, and that Microsoft had taken actions to crush threats to that monopoly

This article is retard
>Sending stuff to space is ridiculously expensive. It costs about $10,000 to launch a single pound of cargo into orbit around Earth. That’s why heavy traditional building materials, such as concrete or steel, are impractical for off-Earth construction sites.
First of all, they are using old space launch costs. They claim it costs roughly 10000 dollars per pound to reach LEO, but its closer to 1500 dollars per pound to LEO with Falcon 9 external launch costs. So off the bat they're already wrong.
Second, for the entire article they assume that these launch costs will remain static. This is a fatal flaw because Mars colonization is NEVER going to happen with high launch costs to LEO. They conveniently ignore that Starship will drastically lower launch costs.

are you telling me this article was bought and paid for by Big Krill shills?

>>12473605
Its a pop sci article so its more likely the author is just retarded

That atomic rockets article makes me wonder if a truly universal airlock is possible. Like that hose-like apparatus used to make an airlock on a downed submarine.

How is this a success?

>You do if there's weather at the runway, or at the launch zone
At the runway, an aircraft has a much more tolerant envelope than a rocket, and the rocket will be well above any inclement weather when it launches.

Oof, bad look for SpaceX. Blue Origin can take their place, they have no failed landings

>>12473623
>Full scale prototype tested an first time altitudes
>10+ minutes of combined raptor burn time
>Stable belly flop
>Demonstrated control with flaps
>Stable tail flip
>Crashed exactly on the landing pad
But you knew all this already right?

Nobody's going to use spacex so they can get taken down for monopoly.

>beezy will be forced to launch with SpaceX
Soon to join Israel and Zuckerberg in the freak anomaly club

So what killed BO? I read there were some serious issues they had with fuel tanks and in particular making the honey comb structure. Small scale tests - works. Fullscale build - fails. That kind of stuff. True?

NS-1 would like a word with you.

I see, thanks

More likely BO forces Congress to push through a law screwing over SpaceX

>>12473635
Don't forget Elon said today the Raptors weren't even NEAR full thrust.

>>12473051
sounds cheap

>>12473636
i don't think the system works like that

>>12473452
What does the RS-25 use? It was reusable at one point

>>12473677
Money.

Anyway

>>12473679
Fucking kek. Must be the same for BE-4

>>12473677
Special startup system on the pad and wonky pressures and shit. It never restarts.

Correct, they'd probably put nine of them on, a ring of six surrounding the central 3.

Side note, did anyone else realize that SN8 was capable of outputting more thrust power than the Delta IV Heavy? The latter only develops 6280 kN of thrust, whereas three Raptors at 100% throttle could do 6600 kN.

Most people in america don't hate elon, most people just think of him as funny space tesla guy. The 0.1% of the population that know more about elon is like 60% supporters and 40% people who hate him.

Jesus. Three Raptor Falcon when?
