1st for laughing at Jeffy

Gentlemen, I need your best spacecraft designs. Assume Starship as the launch platform.

400 TON TO ORBIT PER QUARTER

Let that sink in

Crew Dragon

>>15205025
This space plane

What will spaceflight look like in the 2030s?

Commercial stations, space tourism more prevalent, moon bases?

I want to dream. What can we expect?

>>15205035
the future is shuttle derived

heavy
super heavy
ultra heavy
mega heavy
hyper heavy

>>15205035
Orbital warfare as Russia loses the ability to reliably strike US targets with its rusty missiles.

>>15205042
Ultra Mega Heavy

>>15205042
And where does giga go in this list?

>>15205035
the tethered ring space launcher will lead us to the space future

There is literally no shame in just asking USA for a dragon. It looks like russia is trying to fast track MS-23 with a rollout on the 21st and a launch on the 24th

>>15205062
they didn’t even put thermal blankets on it kek. It’s over

>>15205060
tethered ring!
>>15205062
yeah I wonder what the first national space agency will be that just buys the launch capability straight from spacex and that's it

>>15205068
Well saudi arabia is about to fly astronauts on dragon through axiom. And UAE through NASA, canada has done this as well. None of them have their own launch capability

>>15205076
ah I meant buying and running the rockets personally not the fake space agencies who just rent space lol

>>15205079
No one will be buying and running rockets themselves.

Stay humble anons. Don’t laugh at roscosmos just yet. Remember that starliner is returning to the station with crew

>>15205086
Imagine being the poor bastards slated to be the guinea pigs for the first ride on that death trap when you know you could be getting a comfy dragon ride.

offtopic but Ars Technica comments are like a parody of Reddit it's hilarious

Those brave astronauts are risking their lives for something bigger than themselves. Namely, Boeing's bottom line.

>>15205101
Michael Fincke is backup crew and is slated to fly on the first mission after the crewed test flight. He has faith of the heart though he was in star trek ENT lol

all those small nozzles the STOKE 2nd stage has, are they convergent-divergent nozzles or just convergent nozzles?

>>15205068
the tethered ring is cool as shit and I want it NOW

whats this im hearing about dark energy is created from black holes? so black holes are destroying the universe??

TR-1 was cute, it was a 1/4 scale sounding rocket model of the H-II tested between 1989 and 1990

Is Thinkorbitals shit ever gonna happen

Are there aliens yet?

>>15205144

>>15205191
>Is [thing in space] shit ever gonna happen
Usually no. 99% of the space stuff proposed never happens.
If it's pushed by big companies/space agencies it has a better chance but even then most proposals simply dies. And the more obscure, the less chance it has.

The Axiom station may happen, but certainly not 3 commercial space stations before ~2050

>>15205219
Northrop Axiom Nanoracksn and BO have their contracts to build them by 2030

>>15205263

The planned Hermes reentry demonstrator Maia was estimated in 1987 to cost from 250 to 400 MAU (Basically million of €) and run until 1993, it was not done due to cost.

The Japanese HOPE spaceplane reentry demonstrator program from 1987 to 1998 (excluding the last model scale demonstrator and some preliminary studies) which flew HYFLEX cost 43 billion yen, about 383 million €

Missed opportunity for cooperation for what was fundamentally the same program at the same time.

>>15205323
>3 Starships per day carrying 150 ton each to orbit

We can dream can't we?

>>15205332
2 starship launching in the same day doesn't even seem far fetched at this point kek, I could see it before 2030

>>15205337
Yep. Weekly Starship launches are scheduled for 2024

they took this from you

>>15205356
The X-37 family still needs an expendable upper stage to reach orbit. All reusable spaceplanes converge on either Shuttle or Starship.

>>15205328
The Berger ones can be ok.

>>15205359

>having to fish an expendable crew capsule out of the ocean after every mission is more efficient than a small reusable orbiter that can return directly to the launch center

>>15205366
Congratulations on missing the point of the post so hard.

Why are there so many trannies interested in spaceflight? How do i avoid them?

>>15205413
Man I was just thinking the same thing the other day. I don’t know if it’s because twitter just amplifies terminally online minorities by design, but there are SO FUCKING MANY mentally ill people with rainbow and trans flags out there following space flight.

>>15205413

its all so fucking tiring. all i ever wanted to do was talk about my hobbies without politics.

>>15205420
>>15205413
Autism is linked to transgenderism. Literally. And then you add twitter to the mix

>>15205420
Maybe a result of autism. I follow some of them busy they can make some really fucking cool shit in KSP

>>15205420
A part of it is definitely just amplification. Ive run scripts to scrape profiles through youtube comments relating to touhou, anime and spaceflight (i saw youtube as perfect due to the low barrier of entry to comment and the fact everyone has a google account as opposed to reddit or twitter) and saw very few trannies.

>>15205068
All tratass driving tech could be put to better use eg a system of tether stations to adjust delta-v for transfer to and capture at all the inner planets

>>15205434
to add to this ive lurked in autistic hobby discords and most of the people in them were normal. the type you see talking regularly are the ones who are trannies.
moral of the story: go outside and meet real people. theyre normal

ITS GONNA BE LOUD

Trannies are just what happens when you get rid of the valuable social position of eunuch.

To differ from what many anons posted, my theory is as follows. Trans is an attention seeking behavior. They seek to be the only member or part of a small group where they can be viewed as the first Trans in ...
The only reason you see them so much is because of their attention seeking. They will fight to be put on a pedestal and not acknowledging them is "violence"
Space flight and related sciences produce many small communities, into which attention seekers can assert themselves. This manifests in a seeming over abundance when you look at the sum of these communities.

>>15205714
The only way to increase the meme content of this thing would be to have it deploy a plasma magnet sail and fly to Jupiter.

We have to divide meme drives into those that need new physics and those that need engineering near-miracles tbqf

>>15205721
It's a lot of things. One of the reasons why "Trans" so slippery when people try denouncing it is because it's one label that's been stretched over everything from autogynophiles to failed athletes to political fundamentalists who are tried of being their own cult's untouchables. But a lot of the malignant patterns under the umbrella do display a lot of narcissism.

>>15205730
QI seems to actually be working in the lab though. It looks like simping for Putin hard enough consumed his bad opinion quota so he can get actual science done.

I'm still waiting for Dumitru to deliver.

>>15205743
>I bet the second orbital attempt has legs
It won't because:
1. There's no safe landing pad at Starbase
2. Every Ship/Booster currently in production follows generally the same design as previous ships. Excluding expendable S26 and S27.

Catching a Ship/Booster is just a matter of timing and precision, and while it may be very difficult, it's certainly not impossible. The first few stacks will definitely be expended over the ocean, to make sure the vehicle can safely perform a "landing" procedure.

Almost literally none of it. "SpaceX was rejected almost immediately" MIGHT be the only part that's true.

>>15205937
It's complete nonsense written by an idiot. SpaceX rockets are extremely reliable with the latest Falcon 9 block having a 100% launch success rate over hundreds of launches. They had some early failures, but that was pretty much by design because they tested much more aggressively than other organizations to which I would credit much of their success. What's the context anyway?

>>15205937
The Falcon 9 is the most reliable rocket in the history of ever
More reliable than Soyuz or any other rocket that sent human to space

>>15205984
>The Falcon 9 is the most reliable rocket in the history of ever
Atlas V has a 100% success rate, but if you treat the Falcon upgrade paths the same way as you do Atlas, the current Falcon 9 has a 100% success rate too.
>More reliable than Soyuz or any other rocket that sent human to space
True, strictly in the sense that it's the only rocket that's sent humans into space and the current iteration hasn't failed in flight. Once Starliner starts flying (lol), Atlas V will have a tied record.

Indians will have a launch vehicle, just maybe a small station.
Europe and Japan might have a launch vehicle or something, but low chance.
Russia will be fucked after wrecking it's economy.
The US will have one or two private space stations.
A few Artemis missions now and then if the program doesn't get canned. Gateway will be there but probably almost nothing on the lunar ground.
SpaceX will be maturing the Starship, lots of launches for Starlink and customer stats, some tourism launches now and then, including the Moon orbit ocasionally.
Other launchers will be doing their thing but somewhat better than now. Blue Origin will be doing LEO tourism and RL will be launching stuff from Starlink competitor constellations.
Outer Solar System probes launched during this decade will be arriving by this time, while the first Starship launched probes will be launched and arrive in the same decade.

Wasn’t able to get ISRU working for Methalox, so the Mars Ascent Vehicle will now carry all of its propellant down to the surface. I beefed it up to act as an ascent/descent vehicle for the crew, and it can support 6 Kerbals for 34 days before ascending to low Mars orbit

1/3

>>15206040
Pic of the MEV (mars excursion vehicle) cabin on ascent. 4 crew sit facing upwards, 2 sit horizontally. The lower cabin acts as an airlock. FreeIVA is an amazing mod; it lets you walk and climb around your vessels

>>15206042
We are going
Pic of the MEV separating it’s detachable propellant tanks on ascent. The vehicle’s mission has been changed from a pure ascent vehicle to the crew’s transport to and from the Martian surface. No ISRU means it’s mass doubled though

>>15206044
The fatter MEV means that the launcher had to be beefed up, too. I am currently investigating the trade between using the Pyrios/Dual F-1 boosters, versus “normal” SLS 5 segment boosters.

The launcher is a traditional shuttle derived vehicle. I had to stretch the core and upper stages a lot. The first stage is powered by dual RS-68 engines instead of the quartet of RS-25s in the SLS. They have way worse performance but are way cheaper, and for role play purposes, can support a higher flight rate (1 launch per month)

>>15206050
Oops forgot pic
The upper stage uses a trio of J-2X engines. The MEV is so big that the launcher places it into a suborbital trajectory which lands in the Pacific Ocean. The MEV completed the orbital insertion

>>15205035

Not really no? It’s a working and wealthy state by central Asian standards. Nazarbayev and his familly being sidelined over the past few years ensures it won’t fall to some dynasty, and they’ve always been good enough at balancing between Russia, China, West and Turkey, it doesn’t have significant problems with radical Islamists, ethnic Russian separatism is not a plausible problem thanks to 30 years of emigration and the war in Ukraine.

>>15206698
>ethnic Russian separatism is not a plausible problem thanks to 30 years of emigration and the war in Ukraine.
It's not a plausible problem now. After 5-10 years when Russians reconstitute their forces it can be back on the menu. With the added benefit that driving a wedge between ethnic Russians and Kazaks is way more natural than what happens over Ukraine.

It’s about pushing a narrative. News and media isn’t about telling you the facts anymore, it’s about telling you what you should think

>>15207120
It's not the birds they care about, birds are an interchangeable attack vector like beetles and ocelots. When one doesn't work they switch to another, then another, then another until they get what they want.

The “first generation” Long Marches are all derived from the LM-2A and use (almost) the same core stage with the addition of various boosters and upper stages. The LM-2 (almost always) has no upper stage, the LM-3 has a hydrogen S3, and the LM-4 has a hydrazine S3. Once you look at all the variants side by side it’s really not that confusing, and actually makes a bit more sense than the naming mess the Delta IV Med got stuck with.

The don’t really have any need that makes allocating the needed budget something they want to do. Pakistan’s launched a grand total of nine satellites, only three of which have launched in the last decade, and all of the recent ones have flown on contracted Chinese launches. Not everyone needs their own domestic launch vehicle.

That being said, these was this proposed/rumored vehicle called the “Taimoor” that’s based on Pakistani ballistic missile tech with a few extra exported Chinese stages on top. There may or may not have been a few failed test launches of this thing a few years back.

>>15207728
So much for fixing it

The Liquid propellant engine technology learned from the German rocket engine was transferred to the sustainer stage of the Funryu 4 surface-to-air missile.2'3 Earlier versions of the Funryu missile used solid-propellant rocket motors. Funryu 4, supposedly was 13.1 ft long, 2 ft in diameter, and had a loaded weight of
4190 lb. It was designed to go to 20 mile altitude and a maximum speed of
650 mph. Called Tokuro-2, its LPRE was built by MHI, used the same propel-
lants and essentially the same design concept as the engine for the Shusui air-
craft. The test flight was scheduled for 16 August 1945, but the war ended one
day earlier, and this LPRE has never flown

Make it as easy and straightforward as possible. Basically hold their legs and walk them.
Make it easy even if you have no idea of what you are doing and just want to get something in orbit. Even someone from /x/ should be able to connect a camera and send data back if they can get the money.
Make it very discoverable, explain everything on the website.

It would depend on what you want the constellation to do. SpaceBEE is using picosats to set up a low-bandwidth IOT network for remote sensor systems, so it's certainly viable. You just need a job that can make do with the capabilities you can fit into 2kg payload.

Many people in the industry are similarly obsessed with space as people on here. If anything, that can be a negative, as it's easier for employers to keep wages deflated knowing that a good portion of their engineers are working out of passion rather than a desire for wealth.

It also barely describes anything. That PDF is a big review of all sorts of projects, among which there's a 2-page summary that goes "according to our new model an e-sail may give an order of magnitude more thrust than expected" but it gives absolutely no details whatsoever.

Yes and its all describing e-sail (electric sail) its what MSFC is working on with a possible demonstration mission on a cubesat sometime this decade hopefully

None of this is related to plasma magnet sails as NASA isn't even working on those in any capacity whatsoever, individual third parties are

E-sails and plasma sails mog solar sails, plasma sail mogs e-sail in sheer throoost, but its much more speculative

Looks like JAXA investigated flying HTB on Falcon 9 too

>>15208164
E-sails have the advantage that the thrust vector can be varied in a way that current p-m sails cannot
>by inclining the sail the thrust direction can be modified by up to ∼ 30o. This makes it possible to spiral inward or outward in the solar system by tilting the sail in the appropriate direction to decrease or increase the heliocentric orbital speed, respectively. Thus, even though the radial component of the E-sail thrust vector is always positive, one can still use the system also to tack towards the sun.

>>15208187
Is it same payload as Delta 4????

>>15208200
Nah it’s payload is kind of shite. The cheapest version is $50 million for 4 tons to SSO/5-6 tons to LEO. About half the performance of Delta IV.

>>15208248
>Single core H3 is priced at $45 million
>The price of a Falcon 9 launch has gone up from $62 million to $67 million, SpaceX cites inflation

>>15208248
I don't think that's correct. H3 is $50M for 7.9T to GTO. Falcon 9 is $50M for 5.5T to GTO. I don't see a price / tonnage for F9 to SSO but I would be surprised if they weren't comparable.

>>15208260
The first generation of 21st century rockets are all ageing out. It's a bit of a coincidence that this is happening at the same time that SpaceX inspires a bunch of new players to try and break into the market.

$50 millions is for H3-30, the most basic version with 4 tons to GTO-1500 performances

>>15208257
Clear is life.

>>15208275
This is an H3-22S and it's doing 3T to SSO, the LE-9s are better than you think. H3-30 is not the most basic version. GTO 1500/1800 doesn't matter if the cost of just having more propellant is less than the cost of a more powerful launch vehicle.
