I was highly optimistic at the time, but then the lack of updates and the article about how much of a dumpster fire Amazon Games was and it all made sense that the incredibly rigid structure of Amazon doesn't adapt well to fast-moving industries like vidya and space, where Euraka moments are critical to breakthroughs and success and not every engineer wants to wait around for weeks for middle management to approve of a new test procedure.

Blorg will never improve because Jeff Who is stupifyingly rich. If they don't earn enough this year, then he'll just bail them out. If the government denies a contract, then he'll just bribe someone until he gets what he wants. He's at the point where he is too rich to fail and it's making everyone connected to him dumber for it.

The four booster Ariane 5 WAS considered (in the European sense of the word) as a SLS/Ares V style moon rocket; two launches would get a European lander and capsule to LLO. You would have needed to update the GSE, but since they were going to use it for launching crew they'd probably have built a whole new crew-rated pad anyway. Beyond that you'd need a better cryogenic upper stage than what the A5 had at the time, but that was actually developed and is currently sitting on the top of the Ariane 6. It wasn't the worst proposal Europe's ever floated and it's biggest weakness was the fact that the Euros would need to nut up and actually design a spacecraft they intended to put people in.

The larger versions are pure Kerbal and politics, and would have only ever been proposed as a means to milk some funds for a project that had no chance of ever seeing the light of day.

>>15049478
would 4chan even still exist when we reach that point?

>>15049420
>>15049420
>>15049420
Well there first was twin Vulcain A5 which was a recurrent proposal since the mid 80s (and still had échos today, see the recent twin Prometheus proposal for A6), was supposed to boost the payload by 4 tons or whatever in tbe early versions

Then there was tbe Ariane 5 ECB project with Vinci engines, shelved when ECA failed in 2003 but reappeared in 2009 as Midlife-Evolution, before being cancelled in 2017, the initial target was 12 tons GTO/10.2 TLI/23.2 LEO with evolution possibilities to 15 tons GTO, so they might have squeezed a 30 tons to LEO and 13 tons to TLI Through an iterative evolution of A5

Then there were various flyback liquid booster proposals, can’t find much hard data on it.

There was this SNECMA/SEP proposal of a lunar Ariane 5 from 1995 lol, 35 tons to TLI with a third (proto-Vinci) upper stage

>>15049520
>Then there were various flyback liquid booster proposals, can’t find much hard data on it.
Would winged boosters have worked as an early form of reuse?

>>15049455
I thought they were just less public with any progress, and they would finish that rocket within a few years and have started the next one by now.

>>15049521
There’s no reason they couldn’t, although they have a gnarly mass penalty and there may be issues with tank integrity and heavy lateral heating and loads (unlike the up-down loads on a vertically landing booster)

>>15049524
New Glenn was supposed to fly in 2020 and now it’s NET Q4 2023. It’s even worse than starship with regards to delays lol

>>15049529
Q4 2023? I thought it was Q1 2023

>>15049531
Nope it’s Q4 2023. Sucks

>>15049521
A lot of the problems that make spaceplanes so unattractive in practice aren't nearly as bad when you're only dealing with boost-phase conditions. It's like the difference between Falcon 9 reusing the first stage and trying to reuse the second stage. You would get a bit more effort out of flyback boosters since you wouldn't need to save any fuel for landing or boost-back burns, but you'd lose some performance carrying the weight of the wings all the way to stage separation. Maintenance between flights could be a bigger issue, but that'd depend on how well you designed it.

It was a pretty compelling idea for reusing stages before SpaceX went all in on propulsive landing, but the design costs were always higher than what any of the industry players were willing to contribute.

I kinda wish Starship was an actual winged spaceplane that can achieve flight. I would gladly accept a reduction in payload if it meant Starship could land horizontally on a runway. It would still mog the Shuttle in terms of upmass even if you added wings and beefed it up. You have like a hundred tons of margin to cut into.

We are coming up in 7 years since the first Falcon 9 landing and no one else is even close

>>15049555
I said when it landed that it put them 10 years ahead of the rest of the industry, but I might have undershot on that number.
It's really amazing how nobody else is even close, in the entire world.

>>15049561
They would have been just 10 years ahead if the rest of the world had decided that catching up was something they actually needed to do. ULA and friends spent years pretending that reuse was never economical, Europe insisted that the market that would need to support it would never emerge, India was never in a position to try given their anemic funding, and while China took them reasonably seriously all aerospace dev times are longer when you're working inside of the great wall. 10 years to develop partial reuse isn't a bad timeline when you're actually trying.

>>15049568
>>15049561
At this point SpaceX still has a huge lead over everyone because it took them 2-3 years to really get Falcon 9 reuse perfected. Hell, it took until last year for them to reach 10 flights on a core

>>15049561
Linkspace is still planning a 100km VTVL flight is mid-2023, Deep Blue Aerospace is still trying to do a 10km hop

the thought of a foil tank gliding back is hilarious

>>15049548

>>15049424
They looked great in the early 2000s idk how many anons followed space back then but I did and they were doing autonomous landing testing and it was cool
Idk what happened (cough installing a honeywell guy as CEO) but they went ice cold and thought new shepard was a good idea. And not only that but they STILL THINK NS IS A GOOD IDEA WHICH IS FUCKING RETARDED

I remember when NSF members pieced together the first 'landing' video from the corrupted datastream. Wayyy back in the day

>>15049496
Today is the 10th anniversary of their first orbital insert. I had a long ass post about it but gookmoot’s new website is gay and has popup ads on mobile and fucks up your posts and as soon as I posted it just sent it to the shadow realm
It was just a funny recap on every nation’s response to the launch. Iran’s was the funniest. Columbia was extremely angry for some reason. China’s and Russia’s reactions were interesting

I crudely extended the chamber and switched to autogenously pressurized propane. Tested a few days ago with somewhat disappointing results. The flowrate of propane is way lower that I was expecting. I think either my new fuel solenoid (I fried one yet again, so I had a new one for this test, this time from a cheaper brand) is really restrictive, or there's a clog in by old propane lines I re-used. It made several very loud pops, but did not sustain itself.

I'm going to troubleshoot the lines and solenoid and try again at some point. Also going to make a new throat and nozzle while I'm at it. This one isn't quite optimized for the lower chamber pressure.

>>15049623
post updates please, I can't provide any help but homemade rockets are fucking COOL

>>15049596
Once they return to flight NS is actually well positioned to control all of the suborbital tourism market. It's just that this market is too small to pay back the accrued development costs and doesn't show any real capacity for further growth.

It wouldn't have been that bad of an idea if Blue had won a place on commercial crew. They had plans to develop an intermediate semi-reusable rocket powered by a BE-3 cluster and a crew capsule that would have had some heritage from NS. But they didn't win anything and now they're pushing ahead to their post-intermediate heavy lifter despite it being awkward as hell. Their unwillingness to go with a hardware rich development process didn't help things either.

>>15049518
Probably not, but the idea of an anonymous martian sledding board will live on.

Hey /SFG/, given a recent trailer for Avatar 2, how plausible would this be to actually do? From what can be determined, they're using the ISV antimatter plumes to scorch and cauterize the ground below.

Perhaps it's just film schlock, but cameron has a record of at least being plausible in much of his work.

>>15049735
It's so thin

why are you visiting a museum like some child?

>>15049733
It's unlikely that thin spindly thing would survive reentry. Plus the plumes probably have some crazy radiation emissions so everyone in the ship is fucking dead. Why not just drop bombs? This is fucking retarded.

Honestly why does JAXA even bother having their own rockets, it seems so weird to me
Not that it’s based to have independent launch capability. But… it seems way more cost effective to just buy commercial launches from NASA, ESA, or Pockocmoc

>>15049747
From what I understand the US DoD just gave them all of their hydrogen R&D. So they basically got to skip a bunch of skill trees and go straight to making ze hydromeme. But yeah it still doesn’t make sense. H3 is so strange it never even crosses my mind when I think of ‘upcoming rockets’. Plus expander cycle first stage engines is beyond bizarre. I love JAXA but H3 might be even more retarded than New Glenn

>>15049746
Supplementary material says the rockets are angled just enough so passengers aren't cooked. /TV/ says the aim is to properly colonize in this film. They are not allowed proper bombs, only repurposed mining equipment. Given the engines are designed to operate continuously for 6 months, I guess they are gonna pull themselves back into orbit.

>>15049759
>It's gonna be a space colony = bad film
It's not like there's gonna be sentient catgirls on Mars. Bring on the Starships.

>>15049759
>Supplementary material says the rockets are angled just enough so passengers aren't cooked.
It's not just the hot exhaust gases, it's all the gama rays which when going through an atmosphere will be creating cascades of radiation emissions in all direction.
> They are not allowed proper bombs, only repurposed mining equipment.
so basically they're allowed to do anything they want but they're restricted in how they get to do it. fair enough
that thing is still not going to survive in an atmosphere. much shorter antennas (which are of course static) still need wires to prevent them from bending and getting all fucked up just because of winds.

>>15049776
I'm aware of the gamma rays, but not of the cascading effect. Perhaps it's to cauterize a region from the influences of moon-wide biological AI, burning away all traces of Eywa. I can't help but think of allusions to Mordor, but I doubt Cameron could craft a story like Tolkein, given his holier-than-thou native american alegories.

World building is alright though; I'd like to see what the other planets/moons are like in the system.

>>15049733
These look like stubbier versions of the Venture Star, basically just the drive section with a big payload at the front, lacking all the little spindly bits.
I think that with the ridiculous sustained thrust those engines are capable of, you could just ignore all the usual considerations of reentry and simply hover down all the way through the atmosphere from space at a leisurely pace. The payload might be a drop pod that gets left on the surface while the drive section goes back to space to collect another. The spine of the ship is already designed to deal with what I assume is appreciable constant acceleration during the journey, so if you've got minimal lateral forces during descent/ascent it should be fine.

>>15049755
>H3
It's a pretty linear evolution of Japan's domestic LVs. The H-II was a classic late 80s rocket: two stage hydromeme core with big segmented solids on the sides. It came straight from the thought process that birthed the Ariane 5 and all of the shuttle-derived vehicles that we never got around to building. Unfortunately, it cost $190 million per flight in 1990's money which made it DOA as a commercial offering. The main goal of the H-IIA was to cut that cost in half to $90 million, which it did, and the H-IIA had twenty successful years as a domestic launcher, even if it didn't have any commercial success abroad. The plan for the H3 was to halve the price again down to $45 million, which would be a good place for a commercial rocket if we were living in a world where SpaceX didn't exist.

Hydrogen is awkward as fuck, but if you can make it work, you can make it work. H3's biggest problem is that no one was planning on having a huge paradigm shift as their competition.

Bros, NASA faked the Orion landing, there's no way that piece of shit made it back.

The venture star is based on Dr. Pellegrino's "valkyrie" design, which implicitly assumes beam core designs with very high accelerations and radiators which aren't five hundred kilometers long. The antimatter plume isn't so much a flame as a giant particle beam; if there really were unburnt antimatter in the plume it would mean wasted energy that the starship couldn't use.
I encourage anyone who's interested in starflight to look up some details on the valkyrie. interesting stuff, though pellegrino is somewhat suspect

>>15049904
Has the CCCP/Russia ever landed anything on Mars that didn’t break in 10 seconds? I’m not even joking i’ve just never looked this up before but I can’t name a single mission that successfully landed and transmitted data

>>15049921
lol
lmao

>>15049921
No. They were technically the first to put hardware on mars’ surface by virtue of Mars 2 slamming into the ground after failing. Mars 3 successfully landed but didn’t transmit anything before dying an hero after 2 minutes. Mars 6 was on its way down but didn’t have any commands stored in the computer to actually fire the retrorockets.
They brought china along for phobos-grunt but after that failed the chinks said fuck this and did it themselves with Tianwen-1

The 57 ton version would have needed a lot of extra work to reinforce the center core. This is the bit that SpaceX badly underestimated when they were putting the Falcon Heavy together.

they did it, the laserbeams struck the inner wall, really fast, xrays impinged on the spherical capsule, and fused, but this time it stayed hot for long enough that 1.5X more energy out than was put in. 2 megajoules in, 3 megajoules. they fucking did it. WE DID IT

>>15050929
I bet it's one of those scams where they technically got 2 megajoules to the target to get 3 megajoules out of the reacton but it actually cost 20 megajoules to fire the lasers and 18 just went into heat

>inertial confinement fusion finally gets its proof of concept done
>this is somehow a huge breakthrough
>when it will take countless decades to actually hammer this wacky mechanism into a usable power plant
Not to mention the whole "net energy gain" didn't actually start measuring at the power plug, but instead only looked at the lasers going in and the heat coming out of the pellet. Lasers took dozens of times the energy to create, turning this into another net loss.
Got excited for a second when I first heard about it, but the more I thought and read about it, the less excited I am. Magnetic confinement still seems like the straightest path to fusion power. Which sucks because that it's still le 20 years away.

Very infuriating how few people actually understand what Q-plasma is.
Science media very predictably milking it for all it's worth.
Even ITER which is meant to get a Q of 10, won't actually be able to make electricity, it's still just a test reactor.

No you’re right but this is the first time the booster and ship are actually “almost done.” Ship 24 has one more static fire and then it’s ready to go. Same with Booster 7 unless plans change.

You now remember Angara exists…

Anyone else notice that Russian rockets always use a special boost stage to get to higher orbits, instead of just making a bigger upper stage? Angara, Proton, Soyuz all use either the Block-D/Persei/Briz/ or Fregat for moving payloads to higher orbits

>>15051911

>>15051925
are you with the mole people?

https://youtu.be/X1AKeZMa0pU
Pucker your ASS up my space fiends

>>15051928
Soviet/Russian designs love reusing parts of other less successful projects. The Proton didn't quite have the performance they wanted so they stole the Blok-D off of the N1 and stuck it on top. The Fregat was a originally a modification of the Phobos-1/2 propulsion bus. Adding on a modification of something they're already producing is almost always cheaper in Russia than ditching something that works to design something new.

Also, more "larger" upper stages almost always means playing with hydrogen and the Slavs have less practical experience with than than any other major spaceflight power. Even India has more hydrogen flight time than Russia does.

>>15051969
Yep. Hydrogen has a negative reception nowadays but it has always been the number one in-space upper stage propellant choice.
Take the N1. It only needed to boost 25 tons to TLI (almost only half of Saturn V) but because the USSR didn’t know how to make hydrogen engines, they used kerosene, and N1 ended up being fatter than the Saturn V and needed 30 insanely complex engines

>>15052058
That’s why the base is so fat. But it was also super heavy. More than this, the initial design called for 70 tons to LEO. When it was decided that the N1 would need to carry 95 tons to LEO, they added the inner set of 6 engines which increased the plumbing complexity
