> Boeing’s Starliner program has been in development for over ten years. In 2010, the aerospace company announced it was manufacturing the Boeing CST-100 under NASA’s Commercial Crew Development Space Act Agreement. At the time, Boeing said the spacecraft would be operational by 2015. Then in September 2014, NASA selected Boeing and SpaceX for the CCtCap contracts. Under the contract, Boeing received $4.2 billion, and SpaceX received $2.6 billion.

Such a beautiful machine, lost to time

What is the lightest you could theoretically make a space capsule and rocket capable of getting 1 person into orbit, docked with a station and able to transfer crew, then back again?
Mercury was only about 3,000 pounds but could not dock. could you go lighter with modern materials and construction techniques? would docking and crew transfer add that much overhead?

I’m going to be in Orlando in mid September. Should I try and see if I can watch a launch? Is this something people do?

>>15660950
>SLS Block 2 Cargo

>>15660984
Something like Mercury could be viable if you replace "docking" with "berthing." Just have the capsule get grabbed by a manipulator arm like it's a Dragon 1 or a Cygnus and then have the pilot transfer over via EVA. If actual docking is a requirement then you could use something like a cut down Soyuz. Ditching the orbital module saves you at least a ton of mass, and designing a single-seat capsule gets you a spacecraft that's closer to the Vostok's weight range.

>>15660988
https://www.launchphotography.com/Launch_Viewing_Guide.html

>>15661005
I was thinking about that and how you could cheat by having all the hardware on the station side. then you could just using mercury with no changes and have an arm drag it into a large airlock where the crew is unloaded as they would have been on the ground.

>>15661005
There doesn't need to be a difference between a docking and berthing capsule.
He askes about the theoretically lightest thing.
NASA doesn't want you to know you can just dock to a CBM with rcs thrusters.

Reminder that space isn't actually hard and the rocket equation isn't actually tyrannical when they can waste this much mass on retarded standardized payload dispensers on a smallsoi rocket with purportedly paper thin margins when a latch and tiny spring would do in zero gravity.

>>15661047
reminder that satellites should be made of COTS hardware and electronics and cost $20,000 or less

>>15661047
you need to hold the satelite down as it's accelerating at 5+Gs

>>15661047
The mechanism that opens the door, which doesn't even serve a purpose due to the existence of the fairing, of that faggy ass looking box would be enough to deploy any satellite electron could carry in zero g.

>>15661057
Yes it's easy and doesn't require you encase it in one kg of name branded carbon fiber cuckbox.
You have a hard point and then a tiny latch to unlock it and a tiny spring to push it away.

>>15661065
ok dude, you be the guy who has to explain his 2 milion satellite got smashed because you wanted to min max
most launches have a considerable mass margins anyway

nah

>>15661080
>>15661092
Well and LM7 will actually deliver Chinese to moon and Mars. Will help to built Moon base and so on. And American shit will never fly

>>15661093
Why?

>>15661075
Ok faggot. Start by deleting both ends of the carbon fiber tube.
They're obviously unnecessary.
I don't min max I just want to minimize. They minmax look at the intricate machining and construction. All of it stupid shit you don't need.
This shit is the reason everything costs a bajillion dollars. Use your mass budget for reducing costs not for adding a bunch geeky gizmos that don't do anything.

>>15661084
Yup redditspaced huge reading comprehension fail

>>15661093
What would they gain? They gave up on reusable second stages and Falcon XX because they figured they’d just make BFR/ITS instead.

>>15661093
it doesnt make sense, making f9 upper stage reusable leaves no margin for payload

>>15661104
You’re right by technicality but your reasoning is wrong

>>15661106
what?

>>15661113
Nevermind you’re completely wrong

>>15661114
I'm pretty sure they looked into this
you think a F9 upper stage being reusable would leave significant margin, so much so that it would make sense to design and run them?
what do you base this on?

>>15661116
small rocket same as big rocket just smaller

>>15661116
what if they relaxed the definition of reusable to "the mvac can probably be refurbished and stuck to another tank"
then tried to get it back from orbit with no heat shielding or propulsive landing, just a parachute and fishing it out of the water like a fairing

>>15661116
I base it on speculative renderfag drawings of reusable second stages that make it look like it could work

>>15661118
not how it works retard

>>15661124
grug no believe

>>15661096
>>15661092
Russia's Moon rocket is Angara and China's is LM10.

Both are using two launches for a separate crew and lander.

>>15661133
I'm not sure if the Angara A5V has enough lift to pull off the same mission design as the LM-10. You could divide the mission four ways (one launch each for the capsule and the lander and then two more for lunar transfer stages) but then again you could do that mission with the standard Angara A5 or LM-5.

>>15661093
Starship IS the fully reusable evolution of the Falcon architecture. If you took a Dragon capsule, replaced the trunk with more pressurized space, merged it with the upper stage, and added TPS for reentry you'd get something that looks a lot like a tiny Starship. Making the diameter larger and switching from kerolox/Merlin/Al-Li to subcooled methalox/Raptor/stainless steel was about increasing the delta-V and mass margin enough to do Mars.

>>15661155
Russia plans are less ambitious and their lander will be smaller.

>Yenisei died in late 2021. Angara 5V is Russia's Moon rocket. It's Angara-5 with an URM as an upper stage and a Blok-D/Briz-M as the TLI stage. It's launch pad at Vostochny is close to being completed. It's kinda small, 35-40t to LEO. Needs 2 rockets per Moon landing, 1 for the Orel (reduced mass Orlyonok version) and 1 for a Luna-28 derived 2-person lander. Russian industry were pissed, Rogozin was pissed but that's the best thing they can afford with their abysmal budget. First flight is NET 2028.

>>15661161
I doubt they even end up with a native lander to be dësù

>>15661167
i love the starship. nothing comes close in both soul and capability

>>15661172
my favorite part is how you can't really tell how big it is until you zoom out and get perspective

>>15661161
Well, if the A5V can get the Orel to the moon that means it can handle about 17,000 kg to TLI. That's not quite as much as the LM-10 but it's enough for a mission to be viable. That Luna-28 derived lander is going to have to put on a lot of weight to fit two people onboard. Right now it weighs a ton less than the one man LK lander the first N1 missions were going to use.

>>15661161
Yeah. Roscosmos budget for 2023 is 251 billion rubles per year or 2.5 billion dollars with current exchange rate. And like half of it is for military purposes.

I hate virgin galactic so much

>Starliner in Orbit - edition
Sir, this is the science board. Not fiction.

And here is official Russian moon program. So yeah. Half of it is based on non existing rocket which is not even in development.
But it's from Rogozin time. Since new guy came they only talked about luna-26,27,28

dude, like if you like built a saturn or n1 in orbit with full tanks how far could you go with it

>>15661234
So yeah. US will fucking drill to water reservoir by 2030 and will built fountains with fresh water by 2030. And Russia will launch lander that will search for water in the same year

>>15661238

Saturn V had 18.3km/s DV, assuming you use the CSM engine, & the LM descent & ascent engine. Bet you could get more DV by ditching the LM & just making the CSM bigger. Also, DV could be increased by replacing the F1 engines with vacuum variants (if you want to stick true to the Saturn V form)

Replace the F-1 with vac nozzle F-1Bs, the J-2s with J-2X's and update the electronics and the whole stack gets like 90% cheaper.

>>15661427
Cheaper would be running all RL10s instead of pumping dev money to finish J-2X

>>15661448
That depends. The J-2 had about 1MN of thrust in a vacuum. You'd need 9-10 RL-10s to match that and those clusters are going to add up. There's more than a few good reasons they switched from RL-10s to J-2s when they were designing the S-IVB.

Nah china’s architecture will also be shitty.

>>15661644
you mean titan?
where is the orange haze in that pic

>>15661644
None. Mars might have oil and/or natural gas deposits. Same with venus although I assume the intense thermal nature of the subsurface would have volatilization any deposits long ago. Both were water worlds at some point and if there was ever a biosphere on either planet then there could very well be remnants of that ancient life. Granted this is all very unlikely. But still a nonzero possibility

>flags and boots mission
They could do this type of Moon mission now with Soyuz and by upscaling the Luna-25 lander to hold one cosmonaut and an ascent module. Would probably take several Soyuz and Proton flights to assemble in orbit but doesn't require much expensive new development.

>>15661717
Running an entire manned lunar base off of soyuz alone is so fucking retarded that it almost sounds like something Russia would actually attempt lol

>>15661725
I’m convinced the R-7 family of rockets will simply never die. It will be continuously launched until the heat death of the universe.

>>15661725
Retarded only for a manned moonbase. For a two-man flags and boots mission it would work. Gotta use up all those Soyuz rockets left over from OneWeb.

>>15661717
Soyuz is way too small to have 2+ crew spend a week or more in it.

>>15661717
Soyuz TLI payload is far too small to do a manned mission, Angara 5 is already cutting it close.

>>15661656
I mean, they loose their mind over NASA rovers leaving some scrap behind so you're right

>>15661759
>I drive

>>15661762
With a few Soyuz and Angara flights you could easily assemble something in orbit capable of going to the Moon and landing a cosmonaut

>>15661672

>>15661803
Angara is a more powerful rocket and its launch site is in Russia instead of Kazakhstan.

Soyuz-5 could be turned into a super heavy launch vehicle but Yenisei's development stopped years ago.

>>15661803
The Soyuz-5 is the second coming of the Zenit, which was always a solid workhorse for geostationary launches. Beyond that, there's not really much to it unless Russia really wants to commit to a big deep space program using a Zenit Heavy design, and there's always the issue of just where you plan to launch the damn thing from.

The Angara A1/3/5 has the potential to replace every launcher currently in the Russian fleet and serves as the basis of their more credible deep space plans. If you can get the first stage modules in mass production there's a decent chance it could even give the Soyuz a run for its money on cost. You might even be able to work out a booster reuse plan if you adapt the Block-A recovery systems from the Energia, although I'm not sure if Russia actually has enough payloads to make a reusable launcher a good economic choice.

They're both decent rockets but the Angara has a lot more possibilities to it. I just wish they'd try painting it up in the Soyuz's olive-and-orange because stark white isn't a good look for a Slavic rocket.

>>15661825
>>15661827
Thanks bros. I’ve always heard Angara is shit but I’ve also heard Soyuz-5 is just a shittier zenit. Also the wikipedia page is kind of confusing. It basically says Soyuz-5 is a purely khazakstan thing because of rail transportation limitations, but then toward the end of the article it vaguely says “yenisei could be launched from vostochny” and the contradiction confuses me

https://youtu.be/UqVLP3DKOk4
this is bad

>>15661832
Nah
Only the most over-socialized conformists put any stock in big cities.

>>15661837
Here’s a pic. Now that I think about it, this reads more like “it’s possible to launch Soyuz-5 from vostochny but it won’t be cheap”
At least I think that’s how this is supposed to read

>>15661832
Just going by Google Maps a lot of the nearby Siberian cities look extremely comfy and well-maintained

>>15661837
Soyuz-5 is a Zenit built on slightly wider Proton tooling (4.1m instead of 3.9m). That means that it can't fit through the rail tunnels to get to Vostochny from the factory in Samara since those have a max width of about 3.8m. You could ship it to Plesetsk, but that's is a polar inclinations only space center which doesn't make the most sense for a GEO optimized rocket and you'd still need to build a pad.

If you really want to launch the Soyuz-5 you're either stuck paying the Kazakhs 100 million a year to keep Baikonur open or spending an even worse amount of money to get the old SeaLaunch platform ship working after it spent a decade rusting out in port in Vladivostok. Kazakhstan is the only remotely viable option and Moscow has made it pretty clear over the years they're not interested, no matter how RKK Energia tries to lean on them.

I'm sure there's been some talk of launching a Zenit/S5 based superheavy from Vostochny, but I really doubt there was a lot of serious consideration into solving the problems that would come up before that could happen.

>>15661837
"Angara is shit" comes from the fact that its first flight was in 2014 and its first payload launch was in 2022.

>>15661855
This is a true autism question but does anyone know of any sort of russian rail map? I’m wondering if it would be worth it to just expand all the tunnel diameters but I’d like to see how many mileage this would entail.
Granted, even if it was just one mile that needed expanded a few feet in diameter it would never be finished because of corruption kek

I would unironically live in russia. Both russia and japan have, at one point, expressed a similar idea of setting up dedicated “American” towns for people to immigrate to. I love America but fuck me it’s getting way too depressing with miles of concrete jungles and gridlock traffic to and from my work commute
The extreme of this is wanting to just fuck off to the Moon or Mars but I don’t know if that option will be realistic in our lifetimes or not

>>15661832
So the only operational launch sites actually in Russia are Vostochny and Plesetsk?

>>15661865
Probably a lot at first, but less and less over time. By the end of the Shuttle program NASA was actually refurbing SSMEs at lighting speed

Russia is Nigeria with snow. you're giving in to Kitchen Debate-esque thinking

>>15661847

What's bad about what?

>>15661849
You could get stages from Samra by rail to St. Petersburg, then ship them around the horn to Vladivostok, then get them back on a train again for the final leg up to Vostochny. It's awkward but every Soyuz that Arianespace launched made a similar boat trip so it's not like it's an unsolved problem. I think the real expense would be in building the launch complex. That'd take least a decade and cost God only knows how much.

>>15661857

>>15661879
How is Boca Chica not on here already if they have launched rockets multiple times. Even if they didn’t succeed that’s still obviously an active launch site.

>>15661884
Because then we would have to accept Bozos’ ranch as an active launch site which I will never ever be okay with

>>15661889
They aren’t.

>>15661884
Boca Chica still hasn't officially put anything to orbit yet. The map's also missing Wenchang which is where all of China's bigger launches are happening these days. Heck, the map has Palmachim listed and that's on the same tier as Korea's space launch center which isn't.

Wenchang is a pretty big launch site to be missing from a map.

>>15661951
Trillion dollar company right there

>>15661958
Given that Tesla, Spacex, spinoff Starlink, and eventually Neuralink are all probable future trillion-dollar companies in their own right, I think the theoretical X Corp in 50 years might hit the first quadrillion.
Assuming of course that Elon can properly prepare Young X to take the throne.

>>15662023
Shipping fuel and supplies would be too annoying

>>15662024
why is ITAR cool with this?

>>15662028
Because they aren’t chinks. ITAR isn’t exactly “you can’t share this with anyone”

>>15662015
the us has the exact same murder rate as russia

>>15662016
How many payloads launched from Australia into Earth orbit last year? Now compare that to New Zealand.

>>15662023
It has a great inclination potential but is a tiny island with little infrastructure outside of an airbase.

>>15662028
Because NZ is a close ally and their rockets are built in California.

>>15662032
That were indigenous to New Zealand? None.

>>15662028
ITAR only applies for US jobs.

Mass to LEO includes the mass of the vehicle and remaining fuel at the moment when orbital velocity is reached. This is the standard by which all vehicles are measured. Mass of the Apollo CM, LM, and S-IVB and its remaining fuel at orbital velocity was 143 tons.

Therefore the Space Shuttle was a super heavy-lift launch vehicle. Fight me

>>15662052
I'm not going to. Shuttle haters like to point to its middling payload capacity but they ignore that not counted in that number is 7 crew and facilities to keep them in space for 10 days

This shit makes me mad why can't we have anything good about space? The biggest thing we have is a fucking children's museum. And we can't shut the fuck up about that one astronaut who flew on the shuttle that one time.

>>15662057

>>15662056
We'll need a new name for over 200. Ultra- or mega-?

>>15662052
It was, but most of its payload was used on the Orbiter. Energia was superior here because Buran was an optional payload.

This is why Shuttle-C was proposed, but it was quietly swept under the rug because fewer launches to do things like assemble the ISS meant less money for the companies involved (who were big lobbyists) and it also meant fewer people would get to be astronauts.

>>15662049
Rocket Lab was founded in New Zealand by a New Zealand citizen and still conducts the majority of its space operations there. That's close enough to be considered indigenous.

Credit where credit is due, Rocket Lab was founded in NZ and did sounding rockets before moving to America in order to create an orbital vehicle.

This is the first year they have started launching from Virginia, which will be the only place their upcoming medium lift rocket will launch from.

Didn't know that. You'd think Mahia would be advantageous for polar launches once Neutron is operational.

>>15662103
F9 can do polar launches from KSC by having the barge further south. The same principle applies to Wallops.

>>15662103
NZ's not a bad site for high-inclination launches but Neutron is going to be built in Virginia and shipping it out to Mahia would probably be harder than getting up the road to Kodiak.

>>15662028
ITAR might be cool with it but everyone involved is on a list, since a bunch of people would love to have their own medium lift launch vehicle

Iran is reportedly working on its own rockets, and once they have their own vehicle things get real interesting in the Middle East (and Korea, because Iran's rocket program is derived from North Korean designs).

>>15662103
According to this Rocket Lab user guide their NZ launch site inclination limits are 38 to 120 degrees and their VA launch site inclination limits are 38 to 60 degrees. They do not appear to be planning on doing polar launches with Neutron.
https://www.rocketlabusa.com/assets/Uploads/Electron-Payload-User-Guide-7.0.pdf

We need to harness the power of autism and get someone to make a map of launch sites that includes their inclination limits.

>>15662144
Mossad will probably find a way to sabotage it and set them back at least 15 years
China will cull the norks, most likely. I’m surprised china hasn’t already nipped their little suborbital tests in the bud though. Kim is sending rockets up pretty damn high and they land dangerously close to Japan each time. If they have just one accident (wind blows the wrong way, engine fires just a little bit longer or shorter, slight guidance oversight) and hit mainland Japan I don’t know what the response would be

>>15662103
What will happen to Mahia after Neutron starts flying?

>>15662155
It is still their primary launch site for Electron.

>>15662155
It’ll probably shut down, or be the home of some new NZ startup. I do wonder, once electron is done with RL just slowly become more and more “american” or will they keep a new zealand employee pipeline open? Right now it’s sort of half and half but pretty soon the company is going to have absolutely nothing to do with kiwiland

>>15662154
Japan cannot retaliate. An epsilon sent to pyongyang would probably mean chinese retaliation in return.

>>15662171
Why do you think Japan would launch an Epsilon on such a terrible inclination just to drop a first stage on North Korea?

>>15662183
I meant they would use it as a ballistic missile. I used it loosely because I’m not quite sure what japan actually uses as their dedicated missile, but there’s got to be a reason they are so keen on keeping solids alive

>>15662149
I dunno if this is correct, but they totally could do polar

>>15662194
60 degrees isn't really a polar orbit and the east coast is really too populated to do anything higher.

So if after all these shitshow delays Starliner pulls a 737 Max would that finally sink Boing or are they just a government office at this point.

>>15662399
Even if it’s unsafe and expensive and awful, it’s still good to have an alternative method of getting humans into orbit from US soil

>>15662403
even if dragon started to have issues which would bring up the discussion of switching to boeings system, dragon would still have less issues than starliner. I'm all for competition, but boeing hasn't exactly been competitive. Dream chaser should've gotten the contract.

>>15662328
I actually lived 20min away from their first engine test site (huge abandoned asbestos mine) but sadly I only realized after they left.

>>15662412
It's hard for anyone to compete with SpaceX, they are 10 years ahead of the nearest competitor, have the most valuable asset (real launch data) in spades and all the best talent. Other companies didn't copy their rapid testing style and now the space race is already over.

>>15662403
It is not an alternative until it is deemed safe as it will not fly humans until NASA is satisfied. That is why it got delayed (again) almost a year from when it was supposed to finally do a manned flight.

>>15662412
At the rate things are going it isn't impossible that Dreamchaser will end up flying humans before Starliner.

Why USA can't just ask Russia to use Vostocnhy for a launch if they can't launch in certain direction with existing cosmodromes in US.
Russia just built airport and today first plane landed on Vostochny. So Americans can deliver what they want with planes.

Of course there is no guarantee they will be allowed. But they never asked

>>15662775
>Of course there is no guarantee they will be allowed. But they never asked

International dependencies for critical national capabilities aren't things we want to deal with. Russia has a habit of saying "no" or backing out of agreements whenever it wants something, and that is probably never going to change.

>>15663036
Damn, I've never tried putting two motors together before, I'm still at the amateur level of model rocketry though I've made half a dozen single-use rockets from scratch so far. I had a bunch of C6-5 and C6-3 motors lying around from some old kits, I still do in fact.

>>15663047
At the end of the burn, Estes motors pause a few seconds then fire an ejection charge to force the nosecone/parachute out. I presume anon used that to ignite the upper stage?

>>15663030
>not a lot of people launch them
Probably too many rules against it now, I remember building and launching a model rocket in science class and seeing a bunch in model shops when I was a kid but nothing nowadays.

>>15663036
>E16-0
>Hotstaged
If I'm understanding correctly this makes sense, the number at the end of an engine designation is the number of seconds between meco and the ejection charge, for a C6-3 motor it waits three seconds between cutoff and popping the chute. If your motor is E16-0 it shouldn't have any delay at the end, I'd presume. I've never used that kind before though, so idk.

>>15663047
You're supposed to be able to light an upper stage using a booster stage with a zero second ejection charge (see page 11-12). but for me it fired at about -1.1 seconds. actually looking at fig 1b and 1c maybe this is supposed to happen, but estes lists this engine as burning for 2.1 seconds, so that's what I expected

Anything to have an actual conversation about something that's not completely off-topic or retarded doomerposting.

>new methods of transportation
>it's still just trains
Still, it does look pretty tidy to be able to load all the parts for a vehicle onto one train like that

Sorry, the Apollo 11 LEM descent stage is already a holy site. I suppose the ascent stage is too if it's still wobbling around LLO.

Russia should just rebuild a domestic An-225 and expand the runway at Vostochny.
Or build a giant cargo airship vgh

Kek nice. Hobby lobby carries engines, but like the other anon said: I’m not too sure of the legality within a big city these days. This is very inspiring though; I really need to get into model rocketry and find a place I can drive out to and safely launch from. My old high school had a rocketry team and they would go to JSC and compete with absolutely huge rockets. I really wish I took the time to join them but alas I did newspaper instead to cull my graphic design autism

I don't think the economics for the An-225 really worked out even back when the Soviet Union was still standing. Trains are just too strong. It's like expecting something to compete with the interstate highway system in the US after we invested as much in it as we have.

I've been hearing proposals for cargo airships in the west for at least thirty years, but I still have yet to see one progress past the VC scam phase.

Man, none of this launch complex shit with the concrete and flame diverter and other shit would matter if they'd just launch from the sea.

He’s with cost plus continent anon, drunk OmegA anon, and angry anon who lost 14 members of his family to V2. They’re all in the ether now and are only remembered by the lore masters
