the shuttle was supposed to be a work truck for space. i cant wait until we get a work truck version of starship.

>>15575022
I hope it's not anything like the "work truck" that the space shuttle was cause that thing objectively sucked in so many metrics and absolutely fell short of expectations lol

For mass amounts of hydro lox storage in orbit would it be easier to bring it up as water then electrolyze it when needed? Or would the infrastructure for that be worse than keeping it cryogenically cooled?

>>15575054
The problem of hydrogen storage is the fact it fucking phases through most material tanks. If you had a dense enough tank, cryogenic cooling would be kind of annoying at worst

>>15575109
Give it 7-8 years. SpaceX will build at least one more launch tower in KSC, and high turn over of launches will more or less necessitate that we are such a feat happen. Though I would be happier with four or five pads modernized for Starship standards, but what are you going to do?

Zero chance SpaceX will be doing frequent starship launches from KSC. Once every two weeks tops, still fantastic but not what they need.

>>15575289
You say that, but Spaceforce intends to change that. They've been extremely expansionistic with their mission statement and oversight. Right now they are currently absorbing the NRO. I do not doubt that they intend to enforce military control over the space and pull at least some of the launch pads under their control and out of NASA's.

The earth is flat and stationary with a dome. They are never ever leaving this enclosed plane alive, and neither are you sciencegoys.
CGI is all you get in this life and if you are vaxxed, I know many of you here are well boosted, then the Mars landings will be livestreamed straight into your vaxxed brain.
Also with the latest Neurolink brain processor you'll be able to watch multiple landings at the same time, with the same bitrate and no loss in quality experience.

Retard here : why not use an Unmanned Alpaca as a Mars retrieval sample instead of the JPL gay and complex architecture and launch a "big" multi-stage rocket from the Alpaca with the samples directly to Earth?

The only unnecessary part about JPL's plan is a dedicated sample recovery rover, but getting budget for yet another rover was probably easier than for a full sample recover mission so at least they have something going for them.

If Elon directed the creation of the shittiest, working off the shelf mars rover, and a hypergolic lander for a private MSR, with the intention of selling the returned samples, would (((they))) allow it to happen?

I can't imagine a rover should cost HUNDREDS OF MILLIONS of dollars NASA is smoking dick with their 1.5B to return 8 pounds of dust.

>>15575802
Hundreds of millions is a perfectly reasonable cost for a mars sample return. It’s not going to happen though because Elon wants a human to scoop up the mars dust.

the first starship mission to mars should have a TREE. Some sort of sturdy oak or something. An upgrade over elon's initial early 2000s plan to launch a small flower in a pot with a camera to the surface.

>>15575736

>>15575766
>bunch of fuel from Earth to Mars
Ikr, i thought they could use an inflatable thermal shield or something, but now that is mentioned it, the fuel can be made in Mars via Sabatier process and use the Alpaca to be launch again to orbit.
Also ESA were the ones that would had done the recovery samples rover.
>>15575802
Maybe if the kikes themselves buy the samples and sell them to pieces to the highest bidders.

>>15575804
Alpacatard here, It could serve as an unmanned test Starship along other hardware for the next missions.

Elon musk is a grifter who will never get us to the launch scale most people imagine. "heavy reusability" and "totally safe" are not possible unless you take accurate precautions, which Elon has shown to personally distaste in literally every business opportunity he is apart of.

We should kill him and give NASA his blood money.

The first lunar mission in the history of modern Russia: the launch date of the Luna-25 station has been confirmed.
Now the head of the Department of Nuclear Planetology of the Institute of Space Research (ICI) RAS Igor Mitrofanov confirmed to journalists a more precise date: August 11 is considered as the launch date, the reserve date is August 12, 2023.
Meanwhile, Roscosmos continues to share details on preparations for the launch at Vostochny and has published a new photo. Last week, electrical and pneumatic vacuum checks were carried out — the results are positive and without complaints.
The station will be launched into orbit by a Soyuz-2.1b carrier rocket with a Fregat upper stage. The Luna-25 automatic station should work out the soft landing technology, take and analyze the soil and conduct long-term scientific research, study the upper layer of the surface regolith near the South Pole of the Moon and the lunar exosphere.

>>15576766
>Ah yes elon, the payload door test went perfectly. The payload door won't be the failure point if the payload section has a bulkhead and stringers the final design won't have at the top.

I'm wondering if the bulkhead is apart of the starlink dispenser design and I just didn't know that.

I have a feeling the dispenser will be delightfully counterintuitive
like unironically
They must be on version 5+ of it by now, we saw payload cutouts of some test rings back in the SN1 days

>>15576759
>>15576758

>>15576808
Bros do you think spacex is going to let us vote on these like toonami

is KSP2 good yet

>>15576797
They don't contribute meaningfully to the strength of the door.
The nose and payload barrel have already been tested.
What they care about is the door opening only.
>I'm wondering if the bulkhead is apart of the starlink dispenser design
No retard that would be a waste of mass and serve no purpose.
They use a bulkhead to pressurize it like the nose at launch. With a real nose it wouldn't fit in the test cage.

>>15576805
We have never heard about a booster size increase.
It's also unlikely in the next few years because then the booster wouldnt fit the high bays any more.

Does it even need a door? Just let it be wide open to the elements, the sats can take it.

So is this upcoming Starship rocket designed to be a Mars rocket? Or a starlink delivery rocket?

>>15576821
Well the door opening is what is causing the structural concerns. You wouldn't remediate that by removing the door.
I guess it's for FOD protection and better aerodynamics.

>>15576829
Nigga you don’t want an exposed payload bay when you’re launching a super heavy lift rocket through the earth’s atmosphere

>>15576826
Starlink delivery, orbital refilling tanker, moon lander and mars lander.

>>15576832
F9 fairings are already exposed to the atmosphere at launch, there are holes so no pressure or anything builds up. this is actually sorta common if not standard for fairing designs.

Of course these holes are tiny compared to the starlink hole

>>15576820
>It's also unlikely in the next few years because then the booster wouldnt fit the high bays any more.

Why couldn't they just dismantle the roof and staac more

>>15576826
both. It's a starlink dumper that's also viable as a mars vehicle. The needs of both align because the best rocket design basically does everything. If you need something special just make a variant.

Reminder that tanker Starship will be super short and stubby.

Shuttle was meant to fetch photographic film from spy satellites in high inclination orbits and sufficient lift to access different landing sites regardless of its orbit.
It was never really meant for cheapening space access.

>>15576817
no but its getting better

When do you think they will actually test catching?

>>15576934
third flight if the booster performs during the second.

>>15576937
not a chance

>>15576934
Unpopular opinion; first catch attempt will be the Florida tower. They don’t want to risk boca

>>15576939
The chances of the booster performing well enough all the way down to the ocean aren't that high.
But if it does I fully expect them to try a catch. Now is the best time to do it.
Cadence isn't high so repairing the chopsticks doesn't have as high of an opportunity cost.

>>15576942
The booster can't destroy the OLM nor tower even in a bad crash. It's an empty soda can.
All it can do is break the chopsticks.

LMAO you don't get it do you?
what's the density of methalox?

>>15576895
Yeah because the ring on its own isn't what supports, all those slats will have stringers on both sides.

>>15576982
NIPPPOOOONNNNNN

>>15576977
Basically to spoonfeed you retard.
The tanks will be stretched by a few rings, get three more engines and then the entire payload barrel will be eliminated.
The tankers will be the majority of non LEO mission so maximizing the amount of fuel per flight is critical.

>>15576977
>being this retarded

we have liftoff

>>15576996
>it will carry methane actually. i know i know, very hard for your pee brain very hard to imagine but it's true
Holy shit you really are retarded.
What's the density of methalox faggot nigger?
200 tons of methalox adds 4 meters, 2 ring heights to the propellant tank.

>>15577001
guess what dumb fucker? it's actually more like 150 tons of methane and 50 tons of cryochill hardware and insulation. oh and we're not reengineering the payload bay just because youre mad. keep making shit up it's getting real funny

why not just chill out and wait like a month for the news details/specs to be announced instead of getting all annoyed at each other mates

>>15576997
Lift up her skirt and take a little peek am I right?

>>15577002
>oh and we're not reengineering the payload bay just because youre mad
But they are going to. The tanker payload performance is critical.
They will keep the nose and delete all 20 meters of payload barrel.

>>15576934
I wish they had built a second tower just for catching, and put it away from the launch site to avoid damaging it in a crash or interrupting testing, but they probably didnt have the man power without slowing other shit down. So I guess the plan is to land the boosters in water then try a tower catch when they are sure the control is spot on.

>>15577007
>second tower for catching
why then just add landing legs.
what the tower does is shorten reflight time.
you defeat the purpose having to move the vehicles after landing.

>>15577006
>20 meters
This is wrong. It's more like 10

what are those strands hanging off her?

>>15576948
Yeah falcon 9 couldn't sink a barge despite exploding right into it. The only thing that worries me is starship is a bigger booster and in early tests the booster might have more fuel to make landing easier when they aren't sure about the exact margin needed

>>15577017

SHUT IT DOWN

did the spacex Texas history report from the environmental review req ever get posted?

>>15577026
nah. someone should FOIA it

>>15576992
it's japan

how about deleting the payload bay and just not burning the last bit of fuel

>>15577033
Yeah

>>15577009
I meant just until catching is reliable. Then you turn your second catch tower into a launch tower.

spacex has landed like 100 boosters in a row right? and starship is mechanically simpler to land, you have better control on the booster. I don't see why they won't get it first time

>>15576846
>>15576974
I think the confusion started over tanker vs depot

The tanker is shorter because it has no cargo section. But the depot might be longer because the objective is to get as much fuel tank into orbit as possible.

>>15577046
RTLS to chopstick catch is different than leg landing.

>>15577048
There is no reason to make the tanker shorter.

What are some good space/sci fi games on Xbox?

Have been playing allot of Infinite Warfare, Mass Effect and HALO to get my fix but I need something new

>>15577063
They will carry 150-200 tons of fuel.
Are you brain damaged?

>>15577066
Why would they do that?

>>15577063
Then why is it shorter in your picture? I don't know what that mspaint shit is on the right where you can just double the volume of the fuel and oxygen tanks lol

>>15577071
Because that's the payload capacity.
>inb4 he's still talking about depots

>>15577073
Because the guy who made the render is an idiot.
>>15577074
Yeah, for regular payloads. The only thing stopping them from carrying more propellant is having a TWR above 1 so that they can still get off the launch pad. And Starship has more than enough margin to just fill the whole thing with propellant.

>>15577081
>Yeah, for regular payloads. The only thing stopping them from carrying more propellant is having a TWR above 1 so that they can still get off the launch pad. And Starship has more than enough margin to just fill the whole thing with propellant.

Let me see if I understand

Starship can deliver 150 tons of anything to LEO. The propellant mass is 1,200 tons. If we add space for 150 tons of fuel to tanks that hold 1,200 tons, it will almost double the volume of the tanks.

>>15577093
No his point is that if you add inert payload it decreases your delta-v.
If you add fuel it increases it.
The problem is that you need to burn longer and at some point you don't have enough time to circularize before falling back.
He makes a good point though.

splitting hairs about payload is silly, remember this thing is supposed to fly a billion times a year. what matters 10,000% more than some tons here and there is the flight rate and the refurb time.

>>15577105
Also I'm not sure but I think you might actually end up with the same effect of not making it to orbit because the lower your TWR the more gravity loss eats into your delta-v.
I'd be interested to see the numbers.

>>15577108
Being able to deliver 200 tons of propellant to refuel or something like 600 tons is a huge difference. If you're fully refueling a Starship in orbit, that's 4 launches saved. That's 4 launches that can be used for other things.

>>15577105
the fuel is the cargo. It's a tanker. You don't burn the 150 tons of fuel.

>>15577115
I suppose that's true

>>15577108
The more it flies the more the optimizations add up. Think about if you had a nickel for every shitpost

>>15577112
>>15577115
This is interesting. I might do a little simulation.
>>15577118
No think like if you add to much payload your delta-v decreases and you don't make it.
If you add way more fuel to the tanks well you can burn a portion of that and in zero-g it would be strictly better but given the TWR gravity loss balance its not as clear cut.

>>15576424
Yes
But it turns out this variety of ss is stronger at cryo temps than other alloys at a reasonable cost

>>15577122
>No think like if you add to much payload your delta-v decreases and you don't make it.

If the wikipedia page says starship can take 150 tons to LEO it can take 150 tons of satellites, dead cats, or fuel. Delta-v doesn't know what's its carrying.

>>15577126
Anon, adding more fuel increases your delta v.

>>15577126
well, 150 tons of feathers would be heavier than 150 tons of steel

>>15577064
Outer Wilds is a great open world puzzle game in space with a good story.

>>15577127
Yeah but 150 tons of red LEDs would be better, but even better than that would be 50 tons of red, 50 tons of blue to prevent overheating for reusability, and 50 tons of green to improve economy.

>>15576992
No niggers

>Once again following Musk’s five step process, Musk outlined that he is optimistic that HLS will not need the landing thrusters at the top of the lunar Starship. If SpaceX is able to demonstrate that landing on the moon with Raptor will not create too large of a hole in the lunar regolith, they may remove the thrusters from the lunar Starship. While the exact Raptor configuration for lunar Starship has not been decided, it is likely that it’ll be the same as the Earth variant with three sea-level Raptors and three vacuum Raptors.

I wonder if he will send a starship with those high thrusters but not use them, or send a starship without and add them later if it fucks up

>>15577189
tyranny of the rocket equation, etc. Adding more fuel means you need to burn more fuel to reach the same delta V. How much fuel you want to carry to burn is determined by how good your engines are, so that will be fixed. Starship propellant mass is potentially 1200 tons to take 150 tons of cargo/fuel to LEO. You can bring more fuel and burn more fuel, you can deliver 500 tons, but it'll be a lower orbit or not an orbit for long.

And it's been like this since forever.

>>15577200
You're wrong.
What determines delta-v is mass fraction and isp.
The payload barrel is already there therefore filling it with propellant improves the mass fraction.

>>15577205
But I did eat breakfast yesterday.

>>15577205
But I did eat breakfast and you didn’t down me in liquid methane.
