I will never not weep.

SpaceX is launching Starlink V2 on Falcon 9. I thought it was too big to fit inside.

>>15060248
I used to really like Starlink V2 because I though it would force SpaceX to work on SS. Turns out not so.

>>15060248
elon lied, who could have known?

>>15060248
Modified v2s. Nsf has images of that from few months ago.

>>15060261
Oh, right.

>>15060234
Because it's cheap, it's dev costs were paid off fifty years ago, and it's already able to handle 90% of the launches that Russia has planned. If you ditched the RD-107/108 for a RD-120K/RD-193 set up on a Soyuz-3 you wouldn't even need the Angara for anything.

Wait, I'm confused. Since Earth and Orion are lit up here, how come the moon is so dark?

>>15060288
one side of the moon is permanantly dark

>>15060218
Work on the orbital launch mount continues

>>15060288
Looking at the Earth I think Orion just about passed the terminator and is now above the night side

>starship bros, what happened?
They tried so hard not to make the OLM complicated that they just made it even more complicated than it would have otherwise been

>>15060387
why is the OLM complicated in the first place? Is it just a ton of sensors to test everything or is it intrinsically complex because it needs to be?
If it’s the latter, then “load and go ISRU refuel” on Mars seems like it’s not going to happen lol

>>15060218
The tower, it's now became too expensive to fail so they are trying to make orbit test a success.

Do you think any idea how complicated ISRU would be for a vehicle of that size? When you decide to do it, you might as well build a mini-launch site for Ships.

>>15060422
>why?
So much cheaper. OLM has the advantage that it can be "reused" and maintained easily as a permanent structure, so you can fit most of the important technologies Starship needs to function for the first stage on there, making Starships light and cheap as fuck. For example, the 20 outer booster engines can't light or relight on their own; they need the OLM.

It's also very inexpensive and convenient if you don't have to construct flame trenches and massive olympic-sized water pumps under the OLM for sound suppression like oldspace does, so they made the launch pad extremely tall to help mitigate that. Except the leaking gas in the air over time created a giant explosion and they had to add things (presumably sparklers, at least what Elon had in mind). Then the legs and piping were getting TOO toasty so they had to add giant-ass shields. Then the sound/vibrations was still too much so they tried adding FireX (firing some of the inert nitrogen under the pads and mixing it with lots of water). Then they realized the pad concrete would shatter from the force of 33 engines, which it did during 13, so they are now replacing the concrete under OLM with super-concrete

If you make the OLM extremely complex that means you can pump out thousands of incredibly simplistic steel-ring-stitched-together rockets with prefabricated engines out at blistering speeds in the future on what is essentially an assembly line, on the other hand

China mad that Artemis is stealing their space thunder

>Despite initial embarrassment as rockets kept blowing up instead of reaching space, China picked up the pace in the years that followed. American companies, looking for an inexpensive way to put satellites into space, helped China fix its rocket quality problems. In 2003, Boeing ended up agreeing to pay $32 million in fines for violations of American arms exports controls by a company that it had acquired, Hughes Space and Communications.

>...

>Despite limited direct cooperation, Chinese officials say that they have learned important lessons by watching their American counterparts. Chinese officials are glad, for example, that they did not follow an early decision by NASA in the 1970s: to build a large but costly space plane like the space shuttle.

KEK

>...

>But sending a person to the moon has been done. Sending a person to Mars is an even bigger prize for China. It has placed an emphasis on shortening the duration of such a trip, perhaps with nuclear propulsion instead of conventional rocket engines. Officials are also determined that any journey will be a round-trip from which all astronauts return alive and in good health.

>“Technically, it is feasible in theory, but it has huge challenges in engineering because the scale is very large, we have estimated at least 900 days of travel” based on current technologies, Mr. Zhou said.

>With nuclear propulsion, the trip could be trimmed to 500 days, he said, without predicting whether China would adopt that approach.

>>15060469
So china is instead following the same misguided, expensive premise that nuclear is required to send a man to mars? have at it, insects

Will Starship be big enough to have an active shielding system onboard? Most of the constant scary radiation is not bombardment from rays but from ions

>>15060469
In my opinion China should focus on a manned Moon fly by (probably not going to happen before artemis 2 though) or a Venus or Mars fly by (this would be more attainable before america)
Also I know hughes had satellites that flew on long march rockets way back in the early 2000s but I thought the US govt was okay with it? Did they help china out with some engine/rocket problems?? Kek

>>15060476
Passive methods such as a big water tank and cargo, and pointing the engine section toward the sun is enough to deal with a majority of the radiation honestly

>>15060469
Time to put more brakes on SpaceX

Fun fact: Falcon 9 Booster B1058 has flown 14 times so far, since it’s first flight in May of 2020.
Atlas V has launched 13 times since then.
A single Falcon 9 booster has flown more in 2.5 years than the entire Atlas V fleet

Starlink launch in few min

>>15060503
This launch should be 15th launch/landing. Another historic record.

If B1058 was to explode on ascent, would that ground the whole Falcon 9 fleet? It is an older booster on an envelope pushing flight

>>15060505
Yep. Falcon 9 continues to BTFO every other space agency in the world. I have 100% faith that Starship will be in a similar spot by the mid 2020’s

>>15060482
There was a big shortage of launch capacity in the 80s and 90s, mostly because we let the old Atlas and Delta production lines die off so we could feed the shuttle more business and even 1980s Arianespace couldn't keep up with demand.

There was a big push back then to get Chinese and Russian rockets into the western commercial market to help take up the slack, but those had to convert from government run projects to commercial ventures before that could happen; otherwise the Soviets could have subsidized the Proton to the point of being free and undercut all of the western commercial players. The solution was a quota system: each non-western provider would get a few launches over a number of years while they converted to commercial enterprises. Russia and Ukraine went through this process in the 1990s with few incidents, but China was the first, getting their quota allotment back in 1988. Unfortunately, in 1989 Tienanmen Square happened which torpedoed that idea.

China still got regular launches, but that was only because the payload producers have always been a larger segment of the market than the LSPs, and they have political influence to match, and they wanted as many cheap launch options as they could get. The White House had to sign off on every commercial Long March launch individually, but that was something President Clinton had no issue with. Bitch got along way too well with China.

Then in 1996 the LM-3B launching Intelsat 708 crashed into a village and exploded. During the resulting investigation Loral, Hughes, etc found some design issues with the 3B's inertial guidance system. Fixing that resulted in the LM's launch record improving significantly. When they say "Despite initial embarrassment as rockets kept blowing up instead of reaching space," that's what they're talking about.

The ITAR gods didn't approve of this sort of fraternization, so that was the end of Chinese rockets launching commercial payloads.

>>15060516
I think we honestly didn’t believe China would be our geopolitical adversary one day

>reusable rockets

Nixon knew. Mao offered the US a "gift" of ten million Chinese women, but Nixon was smart enough to turn him down. Slick Willy was just a garden variety cryptocommie Democrat.

I think it was more that the people in charge just didn't care because they were personally profiting from the arrangement.

>15th flight
You better stick that landing, son.

WELCOME BACK

It’s a shame, we might not know how many flights a f9 can actually do. We’re likely to see starship replace it well before the cores get to their end of life

Only one more launch until SpaceX hits 60 flights in 2022. Also, with 136 launches , Falcon 9 block 5 has surpassed the total number of Space Shuttle flights (135)

>>15060629
The difference is, every Shuttle flight was manned.

Another soulless and boring launch from SpaceX, very sad.

>>15060640
Apart from orbital attempts of new rockets, the rest is extremely boring.

>>15060635
True but 2 flights failed out of 135 for the shuttle. 0 out of 136 failed for F9BV

>>15060601
Nahhh it’s probably impossible for a F9 core to beat ~20-25 flights with the way they currently do things. Over the years SeX has been autistically minmaxxing stuff they give a shit to inspect/replace. The last booster that failed to land was caused by some engine plumbing problem stemming from this on it’s 14th flight, if I remember correctly. I guess yeah they could always push it further, see what fails, begin inspecting that after 15 flights. And theoretically they could probably get a core to 50 flights with major inspections. There wouldn’t be a point though
Also if it makes you feel better Falcon will likely still be flying into the 2030s and assuming New Glenn comes on line I wouldn’t be surprised if it takes BO a long time to beat whatever record F9 ends up setting (but by that time Super Heavy will likely have the new record)

>>15060640
this better be bait you retard

Apparently the next Starlink launch will be of V2 sats on a Falcon 9

>>15060658
IMO it seems like SpaceX realizes they are very good with their current model of launches and reuse. They can optimize it, but the risk of losing a rocket and payload (or even just a landing failure) far outweighs the gain a slightly faster reuse brings

>>15060218
Still trying to make proper legs maybe.

>>15060658
Falcon will have launch contracts with the Space Force through 2027 and if NSSL-3 is another five year block buy Falcon's all but guaranteed to have a part of that. That'd take it up to at least 2032. NASA's going to want to keep it around for post-ISS crew launches to the new commercial stations as well.

>>15060463
That's the intent, but the practical reality is that offloading so many systems onto the OLM retains all the original system complexity and adds more in the form of moving parts that have to be protected from the launch environment itself. Then they got the ridiculous idea that they could catch the thing instead of putting it on legs, which means it's even more important that nothing goes tits-up in flight. They should never have put so much onto the OLM, because it's breeding system complexity and dramatically increasing the cost of failure.

>>15060534
What was the real point of the gift?

>>15060720
China is really fond of ethnic colonization

Ten million votes is a pretty strong bloc in a democratic election too

>>15060735
Yeah I guessed that it’s just it seemed strange that he would be so willing to give 10 million slant women to presumably marry foreign men when modern day Chinese men hate their women going with foreign men.

I guess at the time he had no shortage of them and the birth rate was so high they literally had to cap it at one but still a weird strategy.

>Falcon rocket familly will unambiguously surpass Atlas familly as the longest succesful launch streak in history if they launch the upcoming planned launch this year

>>15060700
Exactly. On a side note do you think DXL will ever be built? Or will SpaceX want to just offer Starship Cargo? At some point (2035s-2040s) it might actually cost SpaceX MORE to keep falcon and dragon shit online than just doing a SS launch, even if it’s just a dinky 5T of cargo. It will take a while for SS costs to go down and reliability to hit the mark where everyone is comfortable using it, but that day will come

just some news I found.

Russia is developing a new heavy-duty rocket engine that will ensure the flights of spacecraft into deep space. This was announced by the director of the Kaliningrad enterprise OKB "Fakel" (part of Roscosmos) Gennady Abramenkov.

OKB Fakel, under the scientific leadership of the Kurchatov Institute Research Center, is developing a very high-power electric rocket engine, the so-called BPRD [Electrodeless Plasma Rocket Engine]. It will need a nuclear power source. Its tasks will include interplanetary flights, and in the future - flights to the edge of the solar system, "said Abramenkov.

«The entire central channel [of the engine], if it is not protected in any way, will either burn out quickly or the whole will be "eaten up". The walls must be effectively cooled and inside the central channel create such a magnetic field density that the plasma goes without touching the walls, "he added.

When there will be at least a demonstrator of such an engine, it is not reported. But, as Gennady Abramenkov noted, this will take a lot of time, since the engine will use physical principles with which the company's engineers did not work before.

>>15060458
>Advent has taken over our satellite capabilities
I've played enough X-COM to know how that turns out...

>>15060766
They must have seen

https://spaceref.com/newspace-and-tech/improving-the-performance-of-electrodeless-plasma-thrusters-for-space-propulsion/

and decided they wanted to give it a shot. I'm actually pretty blind when it comes to Russian high-energy physics expertise (do they even do electric propulsion at all?) but I've got to respect them for wanting to try something new.

>>15060776
they the nuklon project with MPD thrusters, although i have no idea how fast these engines are.

>>15060765
I'd normally say that NASA wouldn't want to dock something that big to Gateway. The current docking adapter design can only take so much rotational stress before something gives, and getting the shuttle docked back in the day was apparently pushing the limits of what they could deal with. On the other hand, HLS is going to be docking to Gateway eventually and if it can do that there's no reason that a more cargo eccentric version couldn't be used to deliver supplies.

I think SpaceX will at least consider DXL, if only because they're being paid good money to do so. It might not be the most cost effective, but NASA and the DoD have a habit of choosing proven and reliable over newer and cheaper.

>>15060720
Demographic change. Within one generation America could be 10% Chinese.

>>15060766
lol, Russia will never be technologically relevant in spaceflight again

>>15060796
true.

>>15060784
>but NASA and the DoD have a habit of choosing proven and reliable over newer and cheaper.
Yeah but, as you said, they’ve already gone with HLS Starship so they would be very comfortable using it in theory because by default it would be a proven and reliable system (they are helping SeX with the design process, and are putting their own astronauts on it for moon landings after all)
It’ll be interesting to see how it all plays out. I remember anons talking about SX wanting to renegotiate the lunar cargo contract with cargo starships but idk if they were making that up or not. At this point in time that would probably cost SX more of their own money to send up all the tankers to the depot vs just using a single Falcon Heavy and calling it a day

>>15060801
Would be neat if that ever flies

MPD thrusters, scramjet, ramjet, detonation engines, solid and liquid fuel engines, turbojet engines, aerospike engines, Man how many propulsion methods exist out there?

Logically? No since the probability of there being another sentient species with equal or greater intelligence than our own is estimated to be in the 1 in billions. But incase that 1 in billions does somehow happen it's best to have some organization ready to communicate, funding does not have to be massive though just enough to keep the lights on and legislation in place to pump money into them if a first contact situation occurs.

Elon is being turned into the big bad. People are turning against him. I can't talk about how great Starship is without the "rich man bad" thing coming up. I never wanted this to happen, I just wanted him to disrupt the spaceflight industry (and big auto) to drive humanity forward.

The biggest hurdle is the first step to orbit. Once they get the first starship to orbit, the second one will come shortly. Once the 4th one comes, it will be very rapid transition.

>>15061483
Even under conservative assumptions, 10 years from now, Starship should at least be flying at the same cadence Falcon 9 is now

>>15061500
60 Starship launches per year. I would be extremely happy if that were to happen by 2030.

If they were launching 600 per year, I'd worship Musk and pray to his picture on an alter.

>>15061453

Yes all of them at the same time during a transfer window. Good morning sir we are optimistic today sir.

>>15061584
Calm down

>>15061584
Cladding on the mechazilla is literally the progress bar until orbital launch. That is the best indicator right now along with the veeeeery slow creep towards 33 engine long duration test.
No fucking way itll happen 2022 because it takes a week at least between static fire tests, and s24 is currently being re tested after structural reinforcement.

>>15061584
You forgot about launch in summer of 2021.

An interesting result from the DART impact: if you're on an asteroid and you have a mass driver, shooting stuff *towards* the asteroid will get you more delta-V than simply shooting towards space

>>15061619
depends on the specific impulse of your mass driver meaning what kinda mass you're driving

>>15061643
basically if your exhaust is made of DART spacecraft it's better to eat the losses and exhaust roggs instead.
if it were hydrogen plasma it absolutely wouldn't be.

>>15061643
Yeah, obviously your global isp will be garbage if you're shooting the asteroid
And yes, it depends on the asteroid, impactor, impactor speed, etc. but still, it feels quite counter-intuitive

They had too many. In traditional Chinese culture a family needs sons or the family will die out (because daughters get married and leave the family). Not having enough sons was considered the biggest moral failing, because it leaves no one to honor your ancestors. Daughters were traditionally not as well cared for because they were being raised for someone else ("I cannot imagine anything more cucked...").

As a result couples "re-rolled" every time they had a daughter and stopped once they had a son. That strategy results in twice as many girls as boys. Having too many women further devalues them and makes people want sons even more...

>>15061733

This would have given 20 million nice hapa kids while China would have an even worse demographic problem, seems win-win

>>15061764
No you fucking mong, even disregarding basic game theory that tells you to fuckoff, let us put this into spaceflight terms:
Hapas are mentally unstable (bad for long term spaceflight transit as this makes it even harder to select space transit resilient women), retarded (bad for making rockets), have identity crises that fracture existing stable societies (existing stable societies are necessary for supply chains leading to high technology), and have a spirituality that is less compatible with spaceflight.

>>15061831
>>15061812
They're not doing anything of the sort. They could have bid on a nuclear thermal engine contract if they wanted to or partnered with one of the companies who won. A cursory glance at the Mars mission architectures will tell you that chemical is better. Inb4 I summon that one autistic retard who thinks that a 2039 nuclear thermal mission once proposed by NASA will beat SpaceX.

>>15061831
Spacex didnt even bid to design one in a recent contracting round.

>>15061843
we probably have many more generations yet of chemical engines. hydrogen or something exotic would be fine for in-space propulsion. take a look at impulse space

Nuclear is a meme honestly

>>15061875
>>15061843
Retard. Just because they didn't bid doesn't mean theyre not interested.

>>15061885
What else do you propose for long distance space travel, just to travel to Mars Starship needs million refuels.

>>15061891
Clearly they don't even want to put their foot in the door. Cope and seethe, ma'am, cope and seethe.
>>15061896
Nuclear thermal requires as many tanker flights, only they're to a higher orbit because NASA doesn't want to start up a reactor in LEO.

>>15061891
They're 100% not interested

>>15061905
>Nuclear thermal requires as many tanker flights
>tanker flights

Anybody else have a hard time translating MuskRat retard-speak into English?

>>15061896
it needs one refuel, the depot will already be full

>>15061905
They have the foot in the door. They don't want to work on it right now because of work overload.

>>15061912
Ah yes, fuel at the depot will arrive magically.

>>15061917
Yes. Isru in orbit, gathering CO2 from earth atmosphere.

I got 99 problems but a fuel ain't one. Also fuel cost would be 1/1000th of rocket so irrelevant

>>15061917
think harder

>>15061812
Yes, but he wasn't talking about space flight.

>>15061911
That is already translated into English, retard. You could say refueling flights/launches but they would be bringing up tanks full of liquid hydrogen and then assembling them in orbit, unlike the Starship architecture which just needs the fuel.
>>15061915
>They have the foot in the door.
In what sense? Their competitors are already working on nuclear thermal engines because it's the new cash cow for old space and supported by idiots who don't know any better.

Say that again when they actually test all engines.

>>15061896
nuclear has barely better isp than hydromeme

I mean they can still hypothetically land the booster on a pad?

>>15061971
They already do with f9.

It's easier with starship booster cause it can hover.

It's like he doesn't even care

>>15061961
they'll need to invent better concrete before they can do that

>>15061983
What about Alabama concrete?

Why shouldn't this happen?

>>15061963
and at least hydrogen is abumdant. i shover to think how much nuclear engines would cost per kg per delta v

>>15061972
but the legs could be a problem or so I've heard

>>15061999
No legs

>>15061988
nah I'm thinking Ohio

>>15062002
what about fireborn Hawaiian concrete?

>>15061896
>What else do you propose for long distance space travel, just to travel to Mars Starship needs million refuels.
You have this backwards, Mars would be an ideal case for NTP because of the short distances involved but it's still not very useful there because the mass penalty eats much of the gain from higher Isp and without aerobraking and direct entry the mission needs at least 5 km/s more delta-v, as well as it's own lander, so it's already at a disadvantage compared to Starship.

For virtually all other bodies in our solar system lower thrust but higher delta-v spacecraft would straight up embarrass NTP. The exception is pulsed nuclear thermal but that's so far out there it's not a serious alternative, much like the fission fragment rocket.

why not build a space station strap some meme electric propulsion engines on it and take a nice luxurious trip to mars to then keep living on said space station since groundside is for suckers

>>15062070

The Artemis Accords list is basically a pre-approved international client list for SpaceX, and as long as Ariane keeps dragging its feet, ULA has Blue Origin dragging it down, and India, Japan, Korea and Israel all have low cadence and low payload weight, that makes him the only game in town.

>>15062070

Check how much energy is Germany producing out of 60 GW of their capacity.

>>15062651
Germany is one of the worst places in the world for solar. Using solar there is just as dumb as using it for a gas giant orbiter, but solar does have its places.

Digging through old public NSF posts, apparently the Stoke rocket is another fucking smallsat launcher.

>>15062655
I would honestly rather have SSTO spaceplane companies than VTOL smallsat launchers at this point. At least spaceplanes can scale up enough for passengers.

>>15062660
I can't believe this big cutie already exists and is flying and NO ONE is building a launch vehicle for it.

>>15062663
They're building hypersonic spaceplanes for it.

War criminal reports Russians have starlink terminal detecting machine now.

>>15062663
Two stage to orbit.

>>15062663
Because it doesn't deal with the biggest problem of air launch - having to deal with the horizontal velocity.
We need a way to air launch straight up.

They should try zoom climbing, go full nose up with the plane.

>>15062672
Or just do hypersonic air launch with the orbital spaceplane on the back like this.

>The Russian Sestroretsk arms factory claims that it has developed a Starlink terminal detection radar called Borshchevik which 'is designed to detect and determine the location of Starlink terminals in a 180-degree sector at a distance of up to 10 km.'
maybe a lie but it would be interesting if they actually did have something

>>15062663
because it costs more
