What is their business model
It's very difficult for a component supplier to attain high growth. The only possible outcome with upside for Impulse is an acquisition

>>15028441
Impulse is a space tug company.

>>15028441
the business model is tom wants to do something fun and meaningful yet low stress

>>15028442
Space tugs always end in disaster. This general worshipped the ground beneath Masten for 2+ years before, surprise surprise, the whole thing turned out to be a scam and they went into the drink

Titan lore goes so deep. They pumped everything from RP-1 to NTO to H2 through the LR87 main engines. They also tried gelled alumizime fuel at one point but got too bothered with combustion instability to finish the R&D needed

How long before they start launching Amazon satellites too?

>>15028614
Never ever. Amazon hates SpaceX because Jeff does. He's still their biggest shareholder.

SLS but it’s a new core stage that’s just a ton of clustered apollo-tier AJ-10s

How do I become a good writer, bros?
I really want to write a story set after the collapse of the Martian government in which Deimos tries to become an independent state, but a war ensures between them and what’s left of mars. It’s supposed to be an allegory for the Chechen wars in Russia.
My issues are
1) My writing skills suck and I’ve never published anything before
2). Is it offensive? The Deimans are noble but heavily Muslim and a big theme is radicalization. Meanwhile, the Martians are devout Christians but commit atrocities such as genocide and bombarding population centers.

>Amazon's Dave Limp told @wapodavenport on @PostLive just now they certainly would consider launching Kuiper sats w/SpaceX. F9 is low end of capability they need, maybe FH, but Starship definitely possible. Need to get half of 3,236 satellite constellation up by July 2026 per FCC

>>15028617
>CNSA furiously taking notes

>>15028619
Phobos and Deimos are so small you don't land on them as much as dock with them. It would be the Martian equivalent of Sealand.

>>15028620
1600 satellites in 3.5 years is not thag bad.

>>15028610

>>15028617
Ugh nevermind it has just come to my attention that the trust of the AJ10-137 is 98 kN. For reference one Merlin has a sea level thrust of 850 kN
Damn

>>15028622
The justification will be that several rotating space stations are in the vicinity of Deimos.
The history of post-Soviet conflicts is absolutely fascinating and I am super inspired and stuff.
I had fun writing fake wikipedia articles for fake battles and stuff, but some of this could actually make a decent story. Maybe.

>>15028624
For SpaceX sure, none of the rockets that Amazon has bought launches on have even flown yet and one of the three might not even have its first launch until 2024.

>>15028634
Both A6 and New Glenn are scheduled for 2024 probably. Amazon said they ordered
>18 Ariane 6 launches with 35-40 Kuiper sats
>27 New Glenn launches
>38 Vulcan launches
>9 Atlas V launches
I think you might be right

>>15028632
Just one set of SuperDracos (i.e. 2 engines) has a thrust of 142 kN which is pretty crazy in comparison to Apollo’s giant ass AJ10, and Orion’s dinky ass 27 kN AJ10-190
Anyways you’d want to cluster something like the RD-270 as Glushko intended

>>15028643
>only build two reusable cores
>It’s okay they are certified for 100 launches apiece
>okay actually 50 a piece
>okay actually 25
What could go wrong

>>15028645
Surely they will build more cores. One loss of booster and it’s over, surely they understand this even if they are retards. Also being certified for 25 flights doesn’t even mean they will get 25 flights. It’s just a design goal. Assuming EVERYTHING goes right they will still probably only get 10 flights max out of the things before they start noticing problems and get too scared of blowing up someone’s payload. And again this is assuming everything goes right—it probably won’t. You simply have to expect loss of booster at some point, no way in hell they come out swinging with a perfectly good rocket that can attain 25 reused with zero growing pains

>>15028649
>>15028645
I’ve seen figures that a new Glenn core is like $200 million + just because it’s aluminum isogrid and gigantic

>>15028619
It can be tempting to write a history report on the conflict and drone on about details in the setting, but you gotta resist that urge and write an interesting story set in that conflict. Think about a story to tell that you think shows a point of view that gives opportunity for interesting characters and their growth. The war should be a way to knock your characters down and build them up (doesn't have to be in that order) I personally think that an interesting story follows characters that arent in control of their situations. Follow the point of view of a civilian caught in the middle of it all, or a grunt on the losing side questioning his allegiances, maybe a character that plays both sides to get a meal on his plate and fuel in his ship.
I know the parts of For All Mankind that everyone here hates are the character related stuff, but that was just bad execution. Done right, you can get people passionate about the fates of your characters.
Another tip is that your characters don't necessarily all have to know each other. Experiencing this event is what can tie them together, they don't all need to be the crew of one ship like Firefly. Although it is sometimes really satisfying when two separate characters' paths converge.
Hope this helps

PR talk. They claimed Falcon 9 couldn't launch them due to weights. Which is nonsense. But more so, its because they'd be giving SpaceX too much money.

They are hoping to get on Starship because thats way cheaper such that savings cannot be ignored, but Starship will be booked in advance.

just look at private space companies before (and after) spacex

thus, failed execution in and on itself does not mean the idea itself is bad or unworkable

Now do the FAA files, Elon.

Saw this today from a few nights ago. An occultation of a background star by Titan, as seen by SPHERE on ESO's Very Large Telescope. You can see the ariry rings around the star caused by diffraction, SPHERE uses extreme adaptive optics to reach the fundamental limits of resolution even looking through the atmosphere. Not processed so lots of bad pixels and artifact that all infrared detectors have.

>>15028881
But this image is the really cool one. The star is behind Titan, it should be blocked. But it is now visible at the top and bottom of the disk simultaneously, the light from the star is refracting through Titan's thick atmosphere.
You need perfect alignment to see this. One of the advantages of ground based telescopes is that they're much more flexible to observe something like this quickly.

>SpaceX Plans to Beat NASA in Launching the Biggest Rocket Ever
>NASA’s Space Launch System (SLS) moon rocket officially became the most powerful rocket ever flown when it lifted off in the early morning hours of Nov. 16, putting out a prodigious 4 million kg (8.8 million lbs) of thrust. That comfortably beat the old record holder—the Apollo era’s Saturn 5, with its 3.4 million kg (7.5 million lbs) of thrust.
>But the SLS won’t hold that title for long. As Space.com reports, earlier this week, SpaceX successfully test-fired 11 of the 33 engines on its Brobdingnagian Super Heavy rocket, a beast of a machine that, when all of its engines are lit, will produce more than 7.25 million kg (16 million lbs) of thrust, nearly double that of the SLS.
>Unlike the SLS, of course, Starship hasn’t yet flown, but the engine test is preparatory to a first uncrewed launch of the rocket that could happen later this month—though it is likelier to occur in the first quarter of 2023.

Yuri Borisov visit to Keldysh with full-scale prototype of the Zevs nuclear electric tug

>>15029474
the way you phrase the question itself is flawed, you can't compare them like that like they are competing or equivalent systems
Starshield is a service for integrated payloads on starlink v2 satellites, the satellites provide the bus, communication etc and the glowies can then tack on their own instruments on it
I guess they also provide whole satellites, but the point is to have a cheap system that is integrated to the starlink network and the agencies can then focus just on the payload part, probably sensing capabilities mostly at this point

Honestly it feels like NASA is pretty fucking sick of Boeing at this point and Starship is more than likely going to emerge as the obvious roadmap to Mars especially because NASA is currently getting to know all the major systems and subsystems down to the smallest minute detail and they will have so much familiarity with it

It's an X-Wing Mars shuttle powered by RL10s.

>>15030213
>powered by RL10s
When will the horror finally be allowed to end?

>>15030215
When someone funds finishing the J-2X or someone starts selling 380s Isp methalox vacuum engines to other companies.

>>15030215
RL10s aren’t the worst. They could be better of course, and the price could be dropped by 25% if not more, but they certainly aren’t shit

>>15030219
Fuck the J2X finish AR1

>>15030222
It probably has dropped by at least that much with the RD10C, but good luck ever seeing the sticker price go down.

They're not shit, but they're still underpowered for the roles they get put into. The Atlas V had to get so much performance out of the first stage because the Centaur need so much time to circularize an orbit. The Vulcan has the same problem which is why Smart is the only possible recovery option for ULA to pursue. If you want to get decent thrust out of them you need to cluster them in large numbers which drives up the complexity and the cost. There's a good reason why they dropped the six RL10s on the Saturn IV for the single J-2 on the S-IVB.

>>15030219
Blue Origin would probably be willing to sell BE-3Us once they get their game together.

>>15028619
>2). Is it offensive?

If you have to ask yourself this you will not get published. See; every single big name sci fi author now only publishing shit totally compliant with current year multiracial equality tranny political agenda. You could of course self publish but good luck with that.

Lockmart are giga nigga ultrakikes but come on you to admit it looks tight as fuck.

>>15030153
I wonder if we'll ever reach the point where spaceships can put some focus on design instead of 100% functionality.
I don't think there's any real ship that isn't absolutely fugly except maybe the Space Shuttle.

>>15030253
NTA and my understanding of orbital mechanics and the rocket equation is probably way above average but still not “I play modded KSP and understand everything” tier
Why would the J2 work better then the RL-10 in this particular instance? Isn’t isp way more important than thrust? I’m obviously missing something important

>>15030269
J-2 is ~1000 kN of thrust in vacuum
RL10 is ~100 kN

It's just much bigger.

>>15030269
The old argument against against clustering is that more engines means more points of failure. If losing one engine has a significant chance of scrubbing the mission you're better off having as few dice rolls as possible. You could use 4x RL10Cs on the EUS, or you could use 2x Vincis and get the same performance with a system that's less likely to suffer a failure. They actually talked about doing that but decided that providing Orion's service module was enough of a European contribution to an American jobs program. The S-IVB also ended up being a lot larger than the S-IV and I don't think you could fit the number of RL10s that you would have needed to get enough thrust.

You also have significantly simpler plumbing to get your propellant to the engines, which reduce cost and number of parts that could fail during a launch. No one wants to design plumbing like Superheavy's if you've got any other choice. That shit's nightmarish.

Isp is more important than thrust... to a point. Until your orbit is circularized you still need to worry about gravity losses. If you try to replace an S2 chemical engine with an ion one you're going to run into difficulties getting your payload into orbit. Atlas V and Vulcan could lift significantly larger payloads with far fewer SRBs if they had a more powerful upper stage engine, even if it was a bit less efficient.

>>15030262
It looks like a fat seal.

>>15030291

What are the P,V and O coordinate systems?

>>15030299
That's why using RL10s for what would be an SSTO engine on Mars in MADV is extremely silly.

>>15030302
What the fuck do you want it to use.

>>15030303
Position, Velocity, Orientation

>>15030291
>Isp is more important than thrust... to a point. Until your orbit is circularized you still need to worry about gravity losses.

Because of this depending on what you are trying to do low thrust / high ISP engines take up to double the delta V that traditional chemical engines do.

>>15028633
God that image gets gayer and gayer every time I look at it.
I do like how the image portrays the complete opposite; the destruction of the Martian navy and their orbital shipyard

>>15030305
So ideally an SSTO should optimize for thrust over isp when taking off from the Moon or Mars?

>>15030305
Mars gravity makes ideas that are dumb on Earth a bit less dumb overall. The RL10 could be perfectly workable as an ascent-decent engine on a MADV. The real stupid shows up when you try to keep the hydrolox cold on the Martian surface for any length of time.

>>15030314

Why does NASA keep insisting on hydrolox for upper stage/sustainers when it's rather obvious the isp is detracted significantly by the need for super large cryogenic tanks when methalox would increase their capabilities overall

>>15030487
Time magazine said "ever flown", not to reach orbit.

That's it, I'm changing the /sfg/ super heavy lift vehicle to a five core hydrogen design and there's nothing you can do to stop me.

>>15030516
Hydrolox is unironically great for upper stages (Centaur). Using it for any other application is shit.

>>15030521
Faggot

>>15030525
Solid upper stage. Shuttle srb upper stage.

>>15030516
It's the best option until you get methalox with ~380s vacuum Isp.

>>15030525
>Hydrolox is unironically great for upper stages

Not by cost metrics, which is the only relevant metric unless you have unlimited taxpayer troughs to feed from and even then it's not THAT much better than FFSC methane.

>>15030521
