Did /sfg/ go away there for a little bit?

>>15070874
I think so. Nothing is happening.

>>15070888
What books would you recommend, /sfg/? I want to learn about rockets and spaceflight physics.

>>15070858
Despite being as fat as Delta IV and using hydrogen too, H3 somehow costs $50 million, or less than a new Falcon 9. Wild.

TIL the Japanese fishermen lobby had managed to put a seasonal ban on rocket launchers from the 70s until 2010

Until the late 90s orbital launches from tanegashima were limited to 98 days, expensed to 190 days in the 2000s before being lifted 12 years ago

>>15070996
Don't know too many interesting or universal books on physics and spaceflight, but some shelf-fillers would be:
>Golden book of Astronomy - Rose Wyler
>Soviet Sputniks - (Soviet news booklet 25)
>Invasion of the Moon - Peter Ryan
>The Origins and International Economics of Space Exploration - Sir Bernard Lovell
>Roberth Heinlein's books

>>15070996
I've read 4 space books, enjoyed them all.
>Liftoff!
>Escaping Gravity
>Ignition
>Carrying the fire
Ignition is probably the best for learning about rockets, more specifically chemical ones.

Why didn’t spacex develop a tripropellant LCH4/LH2 raptor? Seems like a better choice for the starship

Did we get an update on the Soyuz MS 22 situation?

Well, I tired food engineering and failed miserably before switching to math. But I never had the chance of getting into spaceflight since the day I was born in the third world anyway.

>>15071173
>food engineering
isn't that just cooking?

>>15071149
Not much, the Russians are apparently certain it’s not a micrometeorid, which still leaves out space debris for mmod strikes

>>15071181
Don't confuse it with gastronomy. This course is about factories, so the lessons where things like chemistry physics and biology. I also considered chemical engineering at first but I failed so fucking hard at the basic chemistry lessons I gave up on that too.

Anons have pointed out that the panels could be cleaned with electrical pulses, and that JPL put no resources into developing this technology.

>>15071279
Would you SHUT THE FUCK UP

>>15071298
Even if wiping technology cost like 10 millions it still would be worth it.

>>15071558
It’s supposed to scare western nations by showing Iran and Russia allying in space

This is gonna sound retarded but I’ve always wondered if some movies and TV that take place with interstellar travel COULD have worked if they were interplanetary (in our solar system) instead.

Like, could Mass effect have worked if it was set in a colonized sol system, with the different races just being people? Could Star Wars work if it was set in our solar system and didn’t have FTL? Could Dune?

Idk.

Never thought I’d see Taylor Marshall on /sfg/ holy shit. The man is based but also very cringe. It’s a very long story
Dr. Marshall is to Catholicism as Mike McCulloch is to physics, you could say

>>15071573
No, the Solar System is just too boring. Look at the major moons of Uranus for example, the biggest 4 are just copy-paste ice-rock balls, the most interesting is Miranda just because of the cliffs.
How would you do Star Wars in the Solar System? I guess Tatooine could be replaced by Mars, Bespin by Venus and Hoth by Europa, but what about the two Forest moons and Dagobah? They would all need to be Earth or some absurd terraformed Moons that would be as much of a stretch as FTL travel.

Because it is mostly about dick waving. Germany, Japan, UK or France could definitely afford their own independent manned space programs on their own if it was a heavy priority. Or they can spend less and send some fuck up there with the Yanks.

>>15071308

>>15071707
ESA doesn't really have a reason to develop their own capsule at the moment, since ESA has been launching on either side's vehicles since the 80's. Despite that they've never really had a problem achieving the same scientific research that both the US and Russia have achieved.

Falcon 9's $50M list price was seen as a standard they had to meet or surpass if they wanted to meet their own price goals. F9 could go a lot cheaper but there's no real point given the options everyone else is bringing to the market right now.

>>15071995
Cost effective rockets are a great stimulatior for jobs, just in the payload segment of the market instead of the launch provider one. Rockets have always been the lesser player to payloads, and I think a lot of the aerospace industry still has their psychology pretty fucked up by the post-cold war consolidations of the 1990s. That, and the ghosts of the McDonnell Douglas management that still refuses to leave.

one of the crazy things you learn from Ignition!, they tried every damn combination of chemicals you can imagine for rocket fuel... EXCEPT methane! For some reason, it was never seriously considered until the present day, and now everyone is trying it out.

>>15072010

>>15072031
I'm pretty sure methane is mentioned at least twice in Ignition. In at least one case it's about germans seeing it's not worth the hassle to deal with it, but technology had improved a lot since then. (and some arguments could be made about hydromeme being an unnecessary stepping stone for first stages after the 70s)

>>15072039

>national geographic

>>15072031
Methane burns cleaner than RP-1, but that's not really a selling point unless you're looking at reusing your engines. For the longest time the only people who were attempting that were chasing the SSTO dream, which meant all of the serious work was centered on hydrogen and MaXiMuM PeRfOrMaNcE. The other differences between methane and RP-1 aren't all that considerable, which meant that the preexisting hydrocarbon infrastructure pushed CH4 out of consideration on cost convenience alone.

>>15072043
Your reply is completely irrelevant to what I posted.

>>15072031
Methane-Chlorine Trifluoride rockets when?

>>15072066
I thought it was going to launch and it just kinda farted and sat there. Very disappointed.

I’ve been kind of obsessed with JAXA’s history and it’s neat that the first Japanese rockets literally used licensed copies of older Delta variants. It wasn’t until the H-II that Japan used a fully domestic engine.

For that matter, ISRO is also interesting. Their liquid fueled Vikrams engine are also licensed copies of a western engine, but this time, ESA’s Viking with powered Ariane 1-4

>>15072111
rocket engine nationality vs the launcher is crazy in general. yes there's a political reason for atlas and antares to use russian engines but it's still weird, intuitively speaking. Especially because that kind of makes antares a little N-1.

>>15072111
I guess think JAXA is the most impressive of the lesser space agencies. They accomplished some very cool things given their size.

>>15072111
ISRO and JAXA are fun to research. Also don’t sleep on Chink rockets. Just because they all have the same livery and don’t really broadcast launches doesn’t mean they aren’t still interesting. LVM 3 (I still call it GSLV Mk III), H3, and Long March 5 are all super interesting

>>15072128

Not only do we get cool launch footage, there's also an exciting chance of cool reentry footage as well!

>>15072128

>>15071952

>>15072125
In the early 90’s, McDonnel was looking for a replacement for the even brand new Delta II. They decided to investigate using a hydrogen oxygen upper stage on a Delta II core to boost payload. There was a moment where they considered importing the cryogenic upper stage of a JAXA H-I rocket (which used the same diameter as the Delta tank already) and using it for their Delta II replacement

In our world, this never happened; Douglas built the gigantic hydrogen oxygen Delta III upper stage, which was adapted for the Delta IV after Boeing bought them. But there is an alternate world out there where “Delta III” as we know it never happened, and instead America used Japanese cryogenic engines instead of RL10s

>>15072128
Chinese rockets are indeed interesting. The basic naming scheme is:
>Long March 1
Dead end, ICBM derived design
>Long March 2, 3, and 4
All use the same hypergolic ICBM as a core, but surrounded with 0,2,or 4 boosters. 2 has no third stage, 3 has a hydrogen third stage, and 4 has a hypergolic third stag

>Long March 5-8
All use the closed cycle kerosene YF-100 engine

>Long March 5
Uses 4 dual YF-100 boosters around a 5 meter hydrogen oxygen core.

>Long March 6
Uses a single YF-100 to power a core stage. Smallsat launcher

>Long March 7 and 8
Both use a YF-100 powered core surrounded by boosters with the same engine

>>15072179
>>15072182
Are they planning on making a closer inspection of the MS-22 leak

ISRO is actually having trouble building GSLV MK3 nowadays. They can build 3 every 2 years, which led to issues because ISRO chose to use them to fly OneWeb instead of Chandrayaan 3. This is what pushed back the launch date.
ISRO’s leader has bragged about generating a profit with the OneWeb launches, and this did indeed piss off a lot of people

>>15072141
There's a lot less official coverage, in the classic soviet style, but there's a lot more unofficial coverage by locals with cell phones. This means analys requires a bit more detective work than usual.

As far as the general state of the industry, it's all still run under the aegis of the PLA. There are a lot of "independent spaceflight companies" but almost all of them are just trying to develop commercialized versions of China's new solid-fuel ICBMs, so there's not much real independence there. There are a lot of different groups designing rockets for severely overlapping bands of capability. The best guess is that China is letting lots of teams try so they can go with whoever gets it working well first.

Most (80% ish) of China's launches are still using the 1st gen Long March 2/3/4 which use their old hypergolic engines, but their production of hydrocarbon and hydrogen engines is picking up speed and should be able to accommodate their lunar ambitions by the time we get to the early 2030s. One of their semicommerical groups recently tried launching the first methane fueled orbital rocket, which would have been a big deal if it had made orbit. The Long March 4D/3B are still workhorses and are launching A LOT of satellites. Whether this is because China is actually building out huge working constellations or is having soviet-style issues with short hardware lifespans is anyone's guess.

There's a lot of talk about chasing reuseability, but China's always had a serious case of follow the leader syndrome; their original design for the Long March 9 was a way to not get shown up by the Ares V promotional materiel that NASA was putting out at the time. They're more serious about reuse than Europe is and are currently testing their own grasshopper equivalents, but they're still a ways off from getting a reusable launch vehicle that works.

>>15072192
>>15072186
SpaceX is in a weird spot where Starlink makes money, but not enough to pay for Mars. If Starlink made a bit more, SpaceX could easily survive without Elon. Elon kind of is fucking retarded because he dropped $40 billion on Twitter when the entire Starship and Starlink program are estimated to be $10 billion, but that’s another story.

In a worst case scenario, SpaceX would effectively become ULA 2.0 or Arianespace 2.0. Starship could fly as much as Falcon 9 does now and cost the same but still dominate the industry. We may not have martian colonies but there is a good chance private flights to LEO on Starship are readily available

Anyways; the genie is out of the bottle with regards to rocket reuse. If SpaceX imploded, someone else would build reusable rockets and take up their mantle.

>>15072194
Do we have any idea what the bottleneck is supposed to be?

>>15072196
Thanks bro. You'd think they'd hop onto their own version of starlink rolled up into that belts and roads stuff. Guess even for them that many launches is out of reach.
>>15072204
afaik there were other investors (think that saudi prince was one of them) and he already owned part of twitter beforehand?
https://www.reuters.com/markets/us/how-will-elon-musk-pay-twitter-2022-10-07/
this is saying he spent $20 billion on it but the specifics don't really matter I guess. We wouldn't have spacex as it is if Elon was a normal person so dumb shit like the twitter buyout or him calling that one diver during the thai cave flooding a pedophile out of nowhere is just also part of the deal lol

anyone think they can find tom mueller's alternate twitter? ;)

>>15072039
Are those boats in the water?

>>15072223
As much trouble as Elon causes, as long as his companies continue to excel, Uncle Sam will tolerate him

No info mate. I wish I knew. Here’s the article for source. ISRO is hoping to build 2 per year eventually

>>15072223
They're going to give it their best try. They're also planning on using the Long March 5 as their rocket of choice for constellation building work, which is going to be pretty fun to watch.

Their constellation is probably going to end up looking a lot more like OneWeb, since the LM-5 can only lift about 50% more than the Falcon 9 to LEO. They'd need a huge increase in YF-100 production to power enough launches to loft a constellation the size of Starlink. Getting a reusable launcher changes that somewhat, but their most reasonable plans are adding recovery to something in the 8 ton/LEO weight class like the Long March 8, so they'd still need a huge number of launches.

>>15072204
>Elon kind of is fucking retarded because he dropped $40 billion on Twitter when the entire Starship and Starlink program are estimated to be $10 billion
AHHHHHHH I'm still seething so much lmao

>>15072291
The entirety of SLS and Orion could singlehandedly be funded with the Twitter purchase

>>15072291
you're basically saying he should take out a 40 billion dollar loan and blow it on starship. except they already did that in the form of selling stock (diluting it). too much andmusk loses control of spacex

>/sfg/ thinks money is what's slowing us down
spacex is the most valuable private company in history at $140 billion

>>15072302
>too much andmusk loses control of spacex
True, but if he really wanted to scratch that itch of spending 40 billion worth of tesla stock so much, he might as well spend it on something space related.

>>15072245
>“We have a good indication that, in two to three years’ timeframe, industry will be able to produce at least four to five vehicles per year.”

Sounds like at least some of the problem has been lack of demand. It was designed as a geostationary launcher that came to market at a time when GTO launches were falling out of style and the Falcon 9 v1.1 was starting to hit its stride at a lower cost.

lol they're just going to copy-paste the F9 production line and flip the bird at California

>>15072711
F9 production wont be copy pasted, thats legacy program. If anything, once Starship achieves orbit/landing/capture, F9 production line @ California is dead.

>>15072718
Not so fast. Retirement will happen gradually. First Starship will take over Starlink launches, then commercial payloads. To fully retire Falcon 9 SpaceX has to do all contracts for NASA and Space Force and they havea lot of them for the next few years.

>>15072155
Wait, wasn’t Mitsubishi partly involved in the D3 upper stage anyway?

>>15071910
I think they're likely selling it at a loss. Hydrolox is a whore.

>>15072272
No.

>>15072741
Retirement w ill happen with older boosters. Maybe F9 line will be kept for few more years, but once Starship proves their thing and if they're cheaper than F9, new F9 line is dead. It will all be flight proven F9s only and then transition to Starship will be forced.

I love how normies due to their elon derangement syndrome had to look up SpaceX on Wikipedia and see who was the next in command after Musk so that they can say this person is actually the one running the company and who deserves all the credit. Nobody even knew who Shotwell was apart from us space autists. Zero nuance, you know, because Elon bad. Similar thing happened with Tom Mueller, till he got angry and deboonked them (https://twitter.com/lrocket/status/1512919230689148929).). The day Gwynne says something controversial or politically incorrect, like defending Elon in that horse sexual scandal?, then it'll turn out that she's a fraud, and steals the credit, and blah blah, and now they'll have to move on onto the next one in the corporate ladder and attribute all the credit to that person. Rinse and repeat.

>>15072994
Dunning-Kruger effect. Armchair specialists push their shitty opinions and gullible idiots believe them and feel like they have uncovered a great mystery.
Did you notice how it's always some literally who that is desperate to debunk Musk? Meanwhile, people in the industry usually respect Musk. It's not always a positive opinion but no one is dumb enough to call Musk a grifter.
