>Gwynne Shotwell told reporters last week that SpaceX sold the rigs; "they were not the right platform." Still interested in sea-based launch platforms, but the company wants to start flying Starship first and understand it before proceeding.

>>15201137
its actually over
without rigs they will never be allowed to launch and land as often as they want

>>15201158
It's not. They have done pretty much nothing with those platforms for months. You really don't need that extra performance of sea launch, close to the equator, because Starship is volume, not mass-constrained.
Also, with multiple launch sites on land, they won't need offshore ones. Today you have Starbase that is almost finished, LC-39A under construction and LC-49A with a few Starship towers in plans. Meanwhile, a sea platform is more difficult to use and wastes a lot of time sailing between the shore and the launch destination.

>>15201172
Tankers are definitely mass-constrained

>>15201172
this isnt sea launch. the platforms would stay in the same spot and be a spaceport island.

>>15201168
>canadian
lmao

>>15201172
If all of what you've just written is true, then why SpaceX even bothered with the oil rigs in the first place?? doesn't make sense

>>15201168
I didn't even know Canada had a Bloostar clone. Sucks to seem them die

>china is expected to have 80 launches this year
>60 government, 20 commercial
YOOOOOOOOOOOOOOOOOOO

>>15201182
It seemed like a good idea at the time and they probably snapped up some platforms that were being sold off at a bargain.

>>15201172
how else are you going to launch more than 5 times a year
even at the cape you can only launch so many times a year

does spacex need to get an air craft carrier

>>15201182
Those numbers are not set in stone. Falcon 9 had a license for up to 6 launches per year. Moreover, 5 launches from Starbase and 24 from LC-39A will be more than enough for a few years.

>>15201192
air launched starship

>>15201194
meant for >>15201192

>>15201186
This is why China is so desperate to get a reusable launch vehicle flying. Their payload production the last couple of years has been absurd.

Speaking of oil rigs, I found some time ago this PDF made by the FAA about the final environmental assessment for Sea Launch, you know that space company that used Zenit rockets and launched them from ocean platforms.
https://www.faa.gov/about/office_org/headquarters_offices/ast/media/final_ea_sea_launch.pdf
Turns out you still have to go through a lengthy environmental review even if launching from international waters. So, it would seem that as of right now there's no place on Earth for SpaceX to freely launch as much and as frequent as they truly want.

>>15201205
From the draft version, page 17
>Because it proposes to launch in international waters, outside the territory of the United States or any foreign country, SLLP must obtain an FAA license to launch.

>>15201209
fucking fascists

Is there any limit to the amount of fusion that can happen in a thermonuclear device compared to the amount of fission? I'm assuming orion drives would want more fusion happening, and most current estimates say ~6000 isp which isn't great for interstellarshit

>>15201137
Either the best decision or the worst decision

>>15201163
Superheavy will attempt RTLS. Starship will land in the ocean.

>>15201186
>60 government, 20 government

>>15201218
rtls on the first flight? sounds like a recipe for massive pad destruction, they should just launch it expendable and send up a big bag of water as payload

>>15201172
Not to mention, you cant quickly recyclea sea launch platform. the logistics would be a fucking nightmare. instead, buildmany coastal launch sites, and Starship can RTLS to any of them from any of them

might be one of the sexiest starships designed

>>15201224
Over a kilometer long, interstellar flybys only, and fully expendable. It looks pretty but it's hot garbage.

>>15201224
>buildmany coastal launch sites
where?

>>15201194
>Moreover, 5 launches from Starbase and 24 from LC-39A will be more than enough for a few years.
they could use all of those launches in a week

>>15201176
Well, that's true, but in the long term, they will make up the minority of launches. The simpler solution is to simply stretch the ship.
If you look at Starlink launcher, you can clearly see that it's not using the whole volume of the payload bay because V2 is too wide to fit inside the nosecone.

>>15201229
yeah, but all non-sailing starship designs might as well be fantasy so it's really choosing out of a big trash heap at this point.

>>15201168
yeah maybe RUD your "rocket test stand" at 7pm saturday night every week instead of 3am monday morning

>>15201228

>>15201234
They could probably get another four or five stuffed in there vertically.

>>15201158
Maintaining those shits was too expensive and they won't be needed for a while. When they need a rig they can buy one from rig-mart

>>15201137
>>15201140
Welp. I guess it’s good news that they haven’t really touched them and didn’t sink millions into upgrading them further, honestly

>>15201312
lol

>>15201151
>low risk
KEK

imagine running a fuel depot in the kuiper belt and stocking shitty sandwiches and nachos

>>15201137
Biggest problem with oil rigs being converted into sea launch platforms is getting the necessary MethalOx at the run rate needed to truly take advantage of SS/SH capabilities. It's probably better to literally just create a mini island out at sea 1/2 kilometer or 1km out from land, and then run a pipe.

>>15201230
all over the world, starting with close US allies (Japan)

>>15201137
>SpaceX: decides to buy oil rigs, will convert them into launch platforms
>sfg: Good idea, oil rigs are cheap, better to launch from international waters, musk = god, etc
>SpaceX: on second thought, let's scrap it all, back to square one
>sfg: oil rigs were a stupid idea, expensive and difficult to work with, only continental launch sites make sense, etc etc
come on, anons

>>15201230
Indonesia!

>>15201328
If the rigs were 90% done a la beff jezos’ carnival cruise ship it would have been dumb

>>15201317
I was being serious hahah. I know they started clearing the decks a while ago but they put it on hold. It’s not like they had towers and a full tank farm

>>15201328
> RIGGED

>>15201328
I've always argued the scalability of oil rigs was dubious. i dont think they want to build fuckhuge mechazillas at sea just yet, if ever

>>15201318
It had it's teething issues, but I'm confident they could have been fixed if McDonnell Douglas and Boeing had stayed in their own lanes. After the buyout Boeing owned both the Delta III and the Zenit-3SL through Sea Launch, and the Zenit was a more attractive rocket that they'd already invested a billion dollars into getting operational. The Delta III still had a dozen launches booked when it was canned so it's not like no one wanted to fly on it.

>>15201347
Oldspace really was a fuck, man

>>15201131
guys, GUYS. HAVE YOU SEEN THE NEWS? THEY ARE TALKING ABOUT UFOS!!!

>>15201141
russians have warplanes that had service ceiling of more than 60k ft. the russians could be selling that as a small rocket launch service.. why the fuck aren't they doing just that?

>>15201366
>russians have warplanes that had service ceiling of more than 60k ft. the russians could be selling that as a small rocket launch service.. why the fuck aren't they doing just that?
They sell space on their actual rockets. Why bother?

>>15201366
One, it wasn't designed by the Soviet Union. Two, no one is buying their launch services anymore. If their space sector was any more isolated they'd all be Chinese.

>>15201366
The Russians has mig-31 air launched rocket projects in the 2000s...
In the end it’s not worth it, they already have cheap and quick launch capability and would rather spend the money on hypersonic missiles

>>15201214
In an Orion design, Isp isn't about the speed od the fission products, it's about how fast they can fire a lump of tungsten (or something else) at the pusher plate. Designs that directly exhaust fusion fuels can have Isp over 30,000s.

>>15201366
UFOS arent real

>>15201374
cuz their rockets launch big sats, not microsats?

>>15201376
>it wasn't designed by the Soviet Union.
do you mean the concept of launching microsats from warplanes?


>Two, no one is buying their launch services anymore
sad IMO. but, isn't that because of costs more than anything else? I guess launching from already existant warplanes would be way cheaper than almost any competitor... I have no idea though.

>>15201200
It’s amazing that Chinese space sector is finally getting on pace after 25 years+ of buildup and investment.

Also scary to think that without spacex America would have been hopelessly behind.

>>15201395
LM5 and LM2F are the only rockets worth their weight putting meaningful things into orbit, and both of those barely ever launch. Everything else barely carries it’s own lifting power into LEO. It just so happens that they have like 10 different types of rockets and they launch them often. There’s a huge disparity between number of launches and actual tonnage to LEO

LEO is old hat. it's all about MEO now

>>15201383
>The Russians has mig-31 air launched rocket projects in the 2000s...
oh, did they? then the talk is useless

>would rather spend the money on hypersonic missiles
I mean, those are completely different things, and income from one could be spent on the other, so why not?

>>15201391
>UFOS arent real
They literally are lol

>>15201366
Dnepr, Proton, and Angara ended up becoming way too expensive for commercial flights. Soyuz was the only one which actually had a market, and that was already being eaten into by Falcon 9

>>15201395
They've got a lot of government encouraged investment from commercial groups and education institutions, which helps things. I think their payload numbers are also being goosed a bit by the fact that their domestic space-rated electronics are trash, or at least they were seven-ish years ago. If a lot of the spy sats they're putting up have Soviet 70s lifespans it would help to explain their launch cadence.

Will passing the Karman Line cure my depression
Probably not

>>15201406

>>15201414
>See an object in the sky

Voila. It's an unidentified flying object.

>>15201168
>Rocket company in Canada
>Tests their engines in Southern Ontario
Man they're retarded, it's not like we don't have space for this.
Anyways their rocket seemed pretty bad, Reaction Dynamics and MLS are still looking good so I'm still hopeful we get a space launch industry going soon

>>15201402
>oh, did they?
Yeah, ishim mainly, needed a pretty extensive redesign of the mig-31, didn’t happen but I think some of the work was reused on ASAT projects

Hermes was going to be comfy for 3

>>15201425
Ishim was a pretty interesting case since it was expected that between the high speed, high altitude separation, the lesser drag and gravity losses and the vacuum optimised launcher it was going to shave off 2km/s of delta v Effectively on the launcher.

>>15201427

>>15201424
isn't MLS using hohol smallsat launchers? The only thing they're building is the launch complex

>>15201435

>>15201427
Remind me again why they cancelled Hermes

>>15201435
For an orbital Laboratory it’s shit
For a crew transfer vehicle to the iss/freedom for 3 it’s luxurious

>>15201439
Too fat; too expensive

>>15201439
It became an expensive oversized spacecraft without a mission.

>>15201412
I’ve thought of this too. What happens after I pass the Karman line? I spend my whole life working towards that goal, but what happens next? Idk

If you could go back in time, how would you unJUST ESA?

>>15201451
Esa station from the 80’s

>>15201451
Declare bankruptcy and cease operations

>>15201453
Kino. It’s too bad Hermes ended up becoming too massive

>>15201456

>>15201436
They're still officially partnered with Yuzhmash but the manufacturers are in Kharkiv and Dnipro so I would be very suprised if that ever came to fruition.
Their only other partner is Reaction Dynamics, a Quebec rocket company, and they're planning their first demo flight this year
https://www.maritimelaunch.com/news/all-canadian-space-launch-solution-plans-inaugural-flight-2023

>>15201439
It would have helped a lot if they could have picked a single design and stuck with it.

>>15201451
That's hard. All of their major problems are rooted in international gridlock and an overabundance of bureaucracy, and you can't just delete those things without completely imploding the organization.

>>15201461(me)
Just checked, their test site is 40min from here. Maybe I should go watch

>>15201461
>check job postings
>they have an opening that fits me almost perfectly (don't have "french (preferred)")
wonder if I should apply... it's kind of hard to get excited over small rockets now a days t b h

>>15201137

Mars is never happening.

>>15201451
No Hermes in the 80s, focus on some recoverable unmanned capsule that can be launched in Ariane 4 that could eventually evolve into something manned , get as much work done on it before the mid 90s budget cuts

Keep the geocomsat development Europe wide instead of the whole 80s split with Olympus and SES,

avoid Lockheed commercialising the proton, get there first, don’t bring Soyuz to Kourou


Earlier and Closer cooperation with the Japanese

DO NOT TRUST THE RUSSIANS WITH ANYTHING RELATED TO MARS

Don’t develop Vulcain, keep using the Ariane 4 base, develop an indigenous Kerolox or Methalox engine with Russian/Nip help in the 90s and use it as base for Ariane 5, never do any big SRB, stick to PAP sized srb if necessary,

Make Galileo ASAP, do not listen to the American with their international earth observing collaboration in the 90s, don’t make Envisat and make smaller sats instead

Hard mode: let small european companied play with decommissioned french ICBM from the 90s onward to put the basis for private launcher entrepreneurship

More boeing! airliner problems, unless these are both really pilot error. This is scary lol

In a certain way, wanting to go to space is in the same level as wanting to get a new game. Of course it will be fun, but it's not something that will make your suddenly happy with your life.
I guess professional astronauts feel more satisfied with it since it is their careers and they dedicated so much of their lives to it, but I don't think it is more than just a fun ride to rich people going in a New Shepard ride.
I don't think my depression can be cured unless I completely change my life style in unreachable ways, or I stuff myself with pills I can't pay for.

>>15201500

>>15201136
Fuck this gay shit, bring back the sonic cruiser. I want to see propfans flying at mach .98

>>15201506
One big design issue was that after Challenger everyone suddenly decided that a next-gen shuttle needed to be able to eject the entire cockpit in the event of an emergency. Hermes was not immune to this madness.

After a few years they abandoned that as impractical and decided to go with ejection seats instead, despite NASA openly admitting those were even worse.

>>15201506
>>15201500
>>15201463
Why did they keep making Hermes bigger? NASA’s HL-20 spaceplane was “only” 13 tons and it could carry 6 crew to LEO.

>>15201524
Cockpit ejection is what high altitude military aircraft use. It was the right choice. They just pussied out because it was difficult.

>>15201527
Hermès was supposed to be a mini-shuttle, robotic arm included, capable of supporting standalone month-long missions. It wasn’t just supposed to be a crew transfer/access vehicle

>>15201328
It made a lot more sense when starship wasn’t planned to have a fuckhuge mechazilla stage 0

>>15201137
>but the company wants to start flying Starship first and understand it before proceeding.
so, two more years until they buy rigs again?

>>15201552
It’s hydrogen

The N1F (2nd from left) replaced the NK-15 engines with the more reliable NK-33s. It would fly in 1974 to support lunar landings by the mid to late 70’s.

By the late 70’s, the upper stages of the N1F would be replaced by hydrogen/oxygen ones. This new rocket would be the N1M.

The final evolution would happen in the 80’s, and see the upper stages be replaced by hydrogen/NUCLEAR stages to support mars missions

>>15201555
The horribly named "N-IFV-II-III" had hydrogen fueled second and third stages, so it wouldn't have weighed nearly as much as it looked like it would. If the very hypothetical numbers Astronautix has are accurate it could have pulled 16m/s2 of acceleration at liftoff, which is actually a bit more than the Falcon 9.

>>15201192
>does spacex need to get an air craft carrier

Los Dos reporting that SpaceX employees and NASA personnel had a meeting about passing the T-30 day mark to Starship OFT1. Static fire was good and everyone is excited.

>>15201137
Probably realized that no matter where they go, even in international waters, the FAA and ITAR will cuck them. Might as well try and force it through in Boca Chica by bribing local faggots. Fuel operations with pipelines and shit would be expensive too, cheaper than USA cocksucker red tape but it seems that it will be unavoidable to pay the zog pitso so oh well. Shame to see it go bye bye but probably not a bad move overall.

>>15202648
All Falcon 9 operations are profitable. Including Starlink.

>>15202648
Considering their customer numbers Falcon 9 runs at a profit, Starlink is probably only mildly in the red, and the Starship project is relatively cheap compared to other moon shot (heh) developments in big companies. I don't think they are in financial trouble, if they were they could just sell more Inspiration 4 style missions to rich fags who want to go.

Literally the entire Texas coast is inhabited or has some sort of state or national park. They also have islands just off the coast usually that are also inhabited but which probably would not at all suit a launch facility. Boca Chica was easily the best location imo, all the complaints are extremely exaggerated. There were less than 30 residents and despite the whining the beach was not heavily used.
All the craw about fucking wildlife is even more ridiculous, that area is genuinely pretty fucking empty. North of it is much more significant protected land and immediately south of the border you have the exact same sort of biome untrammelled for miles and miles and miles. It is a nothingburger and anon is a faggot for being yet another retard swallowing contrarian opinions to pretend to know anything about the area

>mig-31
from google:
>The MiG-31 Foxhound has made several world records. It reached an absolute maximum altitude of 37,650 meters in 1977, and set a time-to-height record of 35,000 meters in 4 minutes, 11.78 seconds, both of which were set by the famous MiG test pilot Alexander Fedotov.
holy fuck...

Starship is going to keep the Raptor's throttled down until it has successfully cleared the tower, right?

It doesn't need anywhere near its max thrust to get off the pad, and if they are still concerned over the cement exploding under the engines, then throttling down to the point where you give yourself a safe margin to clear the tower and then throttle rapidly up to 100% actually might how they do it, right?

>>15202844
The MiG-31 is an upgraded version of the MiG-25. It can reach Mach 3 with copious afterburner use and a willingness to treat its after flight maintenance like SSME rebuilds. The 25 is what scared the US enough to build the F-14 and F-15 to counter it.

>>15202857
Yeah, I was gonna say. The Foxbat and Foxhound could do some wild stuff, so long as you were willing to accept that you basically just killed the airframe's capacity to ever get off the ground again without a complete rebuild, and could stomach replacing the engines entirely since they were usually just slag.

>>15202787

true, but it will have no impact on chinese-made payloads. there will be a bifurcation of launch economies, which is kinda nice since no one else seems to be competing with SpaceX. if china eventually builds a F9 or Starship equivalent, then SpaceX doesnt need to do 100% of the work colonizing Mars. ideally there are more players, but RL and Blue Origin seem to be the only ones with a modicum of interest in trying (and barely at that)

>There are a few options. One is to not use the GA as a direct classifier, but instead use a GA to learn the parameters of another classification model like a neural network. The basic idea of a GA is that it (very roughly speaking) forms a black-box method for searching an arbitrary space for solutions that minimize or maximize some function.
would it be possible thought to write a GA that searches the space of possible computer programs, and selects those that happen to be good at classifying? (No prior knowledge of NNs)

The huge composite casing are made by Avio near Rome, the nozzles are made near Bordeaux, the composite cone (CoCo) are made in Madrid, the attachment between Kongsberg Norway and Lausanne, Switzerland, the skirt in Augsburg. It’s assembled and filled with fuel at Kourou. Kourou can support ~40 P120C production per year between A6 and Vega

How do we increase Vega’s flight rate?

>>15203469
It won't ever be a thing I don't think, but if you were determined you could say fuck the FAA and all the goverbmebt faggots and get yourself to orbit. Mercury rocket was what, like 80 foot long? I saw one at KSC and it didnt seem so big to me. Solid rockets are pretty simple, If you had a bit of rural land, machining skills, money and determination you could DIY a rocket and launch yourself to orbit 100%. Re-entry with amateur systems would be way more difficult but would be a very fucking cool funeral if you had enough of life.

Wow they unironically look cheaper than A5s

>>15203500
I think the main bottleneck right now is the P120C production rate. I heard that's capped at 25 units per year. Completing the Vega-E should help too since you can ditch the Zefiro-9 and AVUM stages for a single methane stage, which should be easier to mass produce.
