>Another satellite operator, though, objected to SpaceX’s proposal. “But commercial expediency is hardly a valid reason for the Commission to bypass the requirements of the Communications Act and grant an application prematurely, in the face of significant doubts as to whether SpaceX has met the public interest standard,” countered Viasat in a Nov. 19 FCC filing.

>Viasat, which has criticized the reliability of Starlink satellites in earlier filings, again raised concerns about premature failures of Starlink satellites. It noted there was no evidence the December launch opportunity was the only one for those satellites, particularly since SpaceX controls the launches.

>“The Commission should balk at SpaceX’s request to provide it with additional authority that it does not yet need when doing so could endanger orbital safety,” it stated. The FCC has yet to act on SpaceX’s request for the polar launch.

Our politicians, in spite of all their numerous failures as leaders and wielders of power, have divined at least one cardinal truth. Human beings LOVE teams, this is true from basically the moment our senses begin to function. The only thing you need do to turn two groups of humans against one-another is give them two differently colored armbands, within mere hours they will factionate.
American poltics is the ultimate in team sport, with the whole fate of the country as the trophy for whoever wins the round. It's an act though, for the politicians very little changes in their lives, sure one team or the other may be marginalized somewhat by the opposite team who have won, but they still continue to accrue wealth and power so long as they keep their positions.
Meanwhile, the divided American people are kept in a state of fighting viciously against one another, instead of recognizing the existential threat to our Republic represented by a body politic fundamentally invested exclusively in selling the country for their own personal enrichment.

Venture Star was projected as being able to fly once a week or something like that, with a 20 ton max payload.
Starship is a TSTO designed to launch multiple times per day, with a >100 ton max payload. Even if Starship only launched once per week it'd still be able to get 5200 tons to orbit in a year, compared to Venture Star's maximum of 1040. If Starship flies at its projected flight rate, it'll be able to put ~73,000 tons into LEO.
Tell me again how SSTO is an advantage?
Oh, and if you're gonna say something about how Starship's multiple-flights-per-day are just a target and not realistic, I'd say it's more realistic that Starship launches more than once per day than Venture Star launching once per week, because the latter is a delicate eggshell hydrolox SSTO. That's assuming they even got Venture Star working, which they would not have been able to do anyway.

Some people do gardening, other people roleplay being right wing militants others roleplay being left wing ones, it changes nothing, there are no political ideas of any kind in the vast majority of the american population. This is the objective truth, if it hurts you its your personal problem.

If Venture Star existed it would have been a barrier to the clearing out of old space and you know it. A "fleet" of two Venture Stars would have flown once every three months to do crew rotation at the ISS and drop off the occasional satellite payload which would have needed to use its own propulsion capabilities to actually reach its final intended geostationary orbit.
VS would have turned out EXACTLY as bad as Shuttle, and every piece of media would hype it up as so efficient because it didn't throw away those solid boosters or the external tank, and all the nerds would jerk themselves off about how cool it was that the tanks were thinner than a dime and the engines were oh-so-close to burning themselves up during every launch and how space is SO hard but it's worth it!
FUCK Venture Star. It was a piece of shit concept and I'm glad it's dead. Old space dinosaurs tripping over their own feet for the past three decades is what has lead directly to the development of Starship, which will be the rocket to actually change everything.

I dont know why people obsess over the shuttle, its objectively clear where it went wrong, it was too ambitious.

Imagine you have a kid, so you put him in piano lessons, he plays ok, fantastic, smart capable boy, LETS FORCE HIM TO BECOME A TRAINED MARINE, SURGEON AND ATHLETE BEFORE AGE 14. You would have never guessed! he didn't do actually any of those things just failed horribly and wasted tons of time and resources, there was no way of anticipating this.

Same thing happened with the shuttle. The us were doing extremely good considering the state of general technology at that time, clearly ahead of everyone, if they had just asked from the shuttle to be a small concept proof of spaceplanes that provide a modest cost benefit over launching with saturn v to pursue incremental savings then everything would have been ok, just a small shuttle, optimized to carry people, small cargo, orbiter on top, no solid boosters, no huge commiting that makes it impossible to cancel for 50 years then it would have been fine, it would have either been a nice intermediate step between the saturn and starship which could have realistically had a less capable version to what we know today started to be constructed in the 80s-90s and everyone would be happy we would be planning permanent mars habitation after having a permanent moon base and already visited mars in an apollo style boots mission.

But no, ohhhh no, congressmen werent gonna have none of that, between them and the airforce they demanded a vehicle capable of putting a trillion tons in orbit, capable of flying like an airplane to basically everywhere, but also it had to be able to snatch satellites, oh oh and manufacture it using these and these components, in these and these states, and have it be cheap but reusable but move enough money, also carry 7 astronauts and...

almost certainly. Starship itself could go wherever it wanted on the moon for cheap. Probably Mars too, though you'd only do that over longer distances.

you fucking fucker goalpost mover left wing tranny cuck who never won anything in your life can only even attempt to pretend like you can be right at anything even in an imaginary setting like this one by using logic more flawed than communism,
you didnt say on mars, you said low gravity worlds with atmospheres.

It's technically possible to use an airplane on mars but id have to run the numbers to see how feasible it is. There are studies for helicopters and blimps, basically by using really fast propellers the low gravity and low atmosphere cancel themselves out and it kinda works.
With a plane light enough with a TWR high enough it might work, but youd probably end up with a rocket that saves a bit of fuel by lift but not more than that.

That has to be a covert way to support spacex and maybe even get ahead of space force in the coming space race (just like not only the air force has planes not only the space force will want space vehicles), but there's no way they are actually considering using it for actual cargo, let's take a look at some of the trillions of flaws this has as a military transport:

-It is completely useless for going into enemy territory, sabotaging it is as easy as driving a car under it. No one but the US can bring down an us airplane, a landing starship is so easy to bring down a kid ridding a bike might do it accidentally. So were talkinga bout peacetime transportation between well established well defended american bases in friendly territories.

-The us already has the capability to deliver nukes to anywhere in the world less than 8-20 minutes on average. Commando teams in more or less that. A strong attack force capable of taking down any single coutnry in the world in 2 hours. If for some reason the whole world bands against the us and also has helps by aliens thus justifying the us using 40% of its military capability it could probably do that in a day or two. This is achieved by a logistic and stockpile network. The only reasonable scenario is where
something that is unique has to be carried fromt he us to the other side of the world. And it has to be on the other side of the world because if its like, half way around the world its starts to become much more atractive to just send it by plane

-Liquid fueled rockets are notoriously bad for rushing, it was attempted with the early icbms by keeping a precarious launch readiness that was extremely complicated and expensive and there was a contingency for actually launching them it but it was estimated that up to 80% of rushed rockets would explode in an emergency launch, good luck justyfing 80% casualty rate before you even engage.

So basically military starship would only be useful if you have to carry something unique and important(but it cant be fragile at all, lol) from the us to EXACTLY the other side of the world (somewhere in the middle of the pacific-indian ocean) and its critical to get it there in 45 minutes instead of 2 hours BUT you have to know at least a week ahead that youre gonna be needing that.Also, only during peacetime, letting know everyone youre gonna do it to avoid political incidents and if there happens to be some land around it has to be 100% friendly territory and even friendlies have to be instructed not to ruin it by mistake.

Makes sense to me they would be. F9 is not as cost optimized as Starship but it's still more optimized than its competitors. Logistical vertical integration leading to cheaper parts overall, Merlin being around a million or less a pop, stringer rather than milled isogrid construction on the tanks as you pointed out, fairing reuse being fairly regular now.

This topic came up before and like then, I respect other disagreements but this part is VERY easy to work around: just use Starships to blast the LZ.

That's not how shit works you fucking retard. The US has to cancel overbudget and overdue R&D all the fucking time, and they definitely care about the bottom line in logistics which covers E2E. Solids are ridiculously impractical for E2E and would have never left the drawing board. If Starship can hit its current cost goals it's close enough to air cargo over long distances to justify the extra expense when you consider much faster timelines, that never would have been true with any other rocket.

On worlds like Mars you'd use rocket propulsion to reach high cruising velocities in the atmosphere, enough that wing surfaces would provide all your lift and let you glide to your destination. On arrival you'd bleed off speed until you began to stall, then you'd fire up your rockets again for propulsive landing. So yeah, basically rocket point to point transport but with some gliding between. This would only be used to reach places remote enough that driving or taking a high speed train are not attractive options.

It would make a lot of sense for SpaceX to build a major space station.
Firstly, it'd be far, far cheaper for them than anyone else. They own Starship, thus will pay only the internal cost of what will already be the cheapest vehicle in the world. Also SpaceX is great at mass production, and you could build the bulk of centrifugal gravity space station with identical parts that fit inside a Starship.
Secondly, a major space station could be kept equipped for a wide variety of servicing jobs, made perhaps easier by artificial gravity. And being a major station, if special parts are required they can be thrown onto a routine shuttle. This would be a major boon to any highly expensive satellites; as long as they can reach the station, they can be fixed up or upgraded extremely cheaply. This greatly reduces the amount of effort (and thus money) that needs to go into guaranteeing a satellite will work flawlessly.
Thirdly and perhaps most importantly, it could be a space hotel. Lots of companies want to offer space tourism to Earth orbit, but all you'd get is a short trip in a cramped space with small windows. The marketability of space tourism would be far greater if say, you got to spend a week in a comfortable hotel with plenty of space to experience space, and SpaceX would not only make more money off their own tourism launches but they'd also make money off of everyone else's tourism launches (assuming they go to the hotel).

But then they need to carry a small hotel with every launch, and limit the density of people since you can't crowd them on the Starship if that's where they'll be spending their entire trip.
Spend a dozen or so Starship flights building a small hotel, and it'll be a far better stay than you could get onboard Starship, and you get to dedicate Starship entirely to transporting lots of people and supplies. The hotel would quickly pay for itself.
Starship could carry hundreds of people and the necessary supplies if going to a hotel, they'd be limited to more like a hundred if Starship was the hotel.

Ok so the atmosphere of the Apollo CSM was 100% oxygen at 5psi(LM is listed at 4.8psi), but the ISS is ~21% oxygen at 14.7 psi.
When nasa does long term studies on human physiological changes aboard the ISS(Scott Kelly's 340 days, etc), are they taking into account that other manned missions to the moon, mars, or anything else will most likely be using an atmosphere more similar to Apollo's than that of the ISS?

The only reason that happened was because nasa was retarded and had Apollo 1 pressurized to 16psi at 100% oxygen on the launchpad while they were running those tests.

Thanks for the video, and I understand your concern, but that's almost 2.5x the pressure of what apollo used. That pressure is closer to what Apollo 1 used than it is to what the other Apollos used.

Thrust is a force, it's measured at any given moment and it's the same regardless of how full/empty the rocket is*. The thrust is somewhat cancelled out by the weight, however, so as the boosters expend fuel there is less downward weight cancelling out the thrust force and therefore you get more and more acceleration as the flight progresses.

*SRBs like those on the Shuttle had their fuel packed in such a way that the thrust would intentionally decrease during Max-Q to decrease the loads on the vehicle and then pick up again afterwards. Similarly the thrust peters out near the end of the flight like you see in >>12387994 because otherwise the acceleration at that point would be too great for the people/payload on board.

Isp is fuel efficiency, sort of like miles per gallon in a car. A tiny econobox car may be able to go a long way on its fuel but it's not going to tow a trailer. Getting to orbit is like having to tow a trailer just to get there, thrust is more important until you get to orbit.
Then once you get to space, a high Isp engine means you can go farther on a given weight of fuel, but says nothing about how fast you will get there. Ion engines are very efficient, but with very little thrust it takes a long time to change velocity.

They don't have the dirt cheap launches of SpaceX or the cheap satellites from economies of scale so how will they even be cost competitive?

Locally they got 20m from BAE and 60m from the UK itself. From the US 37m from Boing, and an undisclosed amount from DARPA for high temperature testing facilities. So it depends on what you value the DARPA contract at. Also I'm mostly 'avin a laugh, it was just a really poor argument. Musk was worth millions not billions when he started SpaceX and they made orbit on less investment than REL has gotten, that being almost entirely internal, and when it started getting significant investment thereafter almost all of it came from launch contracts. You can't ask for launch contracts when you only have a pie in the sky multibillion dollar superproject under development.

The RS-2200 and the other test powerhead were both based on unchanged plumbing from LOX/LH2 engines, I'm not convinced that all of the negatives associated with them are universal to the design. Even if you would have to take a hit to absolute TWR they're still useful as a "universal" engine that can be used in both stages of a two-stage rocket, since they stick close to the optimal efficiency curve at all pressures between 1 bar and vacuum.
If you design large diameter engines you can also use them as a transpiration cooled heatshield that can seamlessly transition into propulsive landing.
Your second stage can essentially be a gigantic capsule, except that instead of parachuting down it can perform a propulsive landing, presumably somewhat like what was proposed for Red Dragon.

I have yet to hear one single good argument for "small Starships". The last time someone tried to make a point about it they argued that it eliminates refueling, which it most certainly doesn't.
I don't know what the safety argument is but I'm not seeing it, what is the part of Starship that you have a safety issue with and how does a mini Starship do anything about it? You still need vehicles designed to do every part of the mission profile, which means you still need to solve every safety concern, just unnecessarily broken up across two vehicles.

You don't need to take a TWR hit and use a melty spike do to the job of a TSTO though. The same basic engine can be used for both stages using bells with different expansion ratios. That's Falcon 9.

Note that the attainable wet-dry mass ratio for hydrolox propellant is way shittier than the attainable wet/dry mass ratio you can achieve with methalox, propalox, kerolox, or really any bipropellant other than hydrolox. There's probably some kind of magic figure that combines specific impulse with density impulse that lets you directly compare propellant choices for certain applications but I don't know what it is.

Oh yeah, I realize that, I don't mean you get better dry mass ratios out of hydrogen. For an SSTO however since you're dragging all your staging with you, most fuels given practical dry mass ratios won't give enough ISP to compensate and push all that into orbit. Apparently you can with hydrogen. Personally I think SSTOs are a dead end and hydrogen first stages are a mistake.

It might be, if you can keep exactly the same weight in tankage then it might actually be easier, but I don't really know and my speculation wouldn't be worth anything because they haven't even built any of the rest of Skylon yet. In the end it would really, really just be much easier to make it a LOX/CH4 two stage rocket. Or even a LOX/CH4 second stage ontop of a LOX/Kerosene booster, for the added "oomph".
IF Skylon can even reach orbit I'd be extremely impressed, because not only is it dragging it's whole dry mass to orbit, but also hybrid engines in which the turbojet part of the engine will be completely useless once it gets up above the atmosphere.

>> No.12389395

>>12389346
Yeah I get that, what I'm saying is that since the performance you actually get out of a stage is a function of mass ratio AND Isp, swapping to a propellant with a 20% lower Isp but three times the density may actually improve the stage delta V that is attainable. It's like how the Falcon 9 upper stage using kerolox has a huge delta V budget, simply because it has a very small dry mass.
For an SSTO you'd need at least 9500 m/s of delta V when fully loaded, assuming you can also get a decent thrust to weight ratio off the pad. Using methalox with a flight-average Isp of 360, your vehicle needs a propellant mass ratio of 93.25%. Using hydrolox with a flight-average Isp of 440, the vehicle can get away with a mass ratio of 89%. That sounds a lot better, but consider the density difference; hydrolox takes up about 2.5 times the volume for the same propellant mass. Being 2.5 times bulkier means that the tanks have more hoop stress at the same internal pressure, and therefore need to be thicker and heavier per unit area, as well as just being much larger in general. The mass of the TPS coating also goes up, because there's more surface area to protect. Finally, hydrolox engines tend to have lower TWR due to needing larger pumps to move the same mass of propellant. These factors combine to mean that getting a 89% propellant mass fraction out of a reusable single stage vehicle which can lift off of the pad fast enough to not experience massive gravity losses and actually attain orbit is fucking HARD.

Something that can give you 25km/s or more of Delta-V. In fact, may as well make it 50km/s or more if you ever want to get back. 3.3km/s to get from LEO to any injection orbit, and to get TJI you need another 3.4, from TJI to a stable LJO costs a whopping 17.2km/s, for a total of 23.9km/s of dV from LEO to LJO.

It's all charged particles following magnetic field lines, so probably. I don't know the methods they propose to drain the VA belts. In principal you'd do it by introducing positive ions to the negative belt and introducing electrons to the positive belt. If you had some kind of long, superconducting wires that you could place into orbit around Jupiter they could act to neutralize both belts simultaneously over a period of time, by essentially bridging the gap between a large voltage potential. Don't take this as facts though, I'm making this shit up based on what I know about electricity and the radiation belts.

What do you mean expectation of energy?
No chemical fuel would be worth going into a gravity well deeper than a mid-sized asteroid to retrieve.
Nuclear fuels (ie deuterium and helium 3) can be much more easily harvested from Uranus and Neptune than Jupiter, and if we have need for fusion fuels we by extension will have fusion propulsion, which means the distance to Uranus and Neptune is no longer a problem. Given this, I'd say that Jupiter will actually be the last gas planet in the solar system that we start to exploit for resources. We may end up neutralizing the radiation belts anyway for convenience's sake, and so that we can access Io and it's large amounts of refractory resources (the largest single supply in the outer solar system).

>all that tall shit crowding the pad
I'm pretty sure they'd much rather design their infrastructure to stay low and away from the launch pad, especially because they're still kicking around the idea of getting landing accuracy good enough to reliably set the booster down back onto the launch pad during its landing burn.
Does anyone see any major issue with the idea of the launch tower/crane being capable of leaning back like the Falcon 9 Strongback during a launch? The only thing I can think of is that it would be big, but the solution to trying to build something big that doesn't need to fly is "use thicker steel" so I don't think it's impossible.

Just imagine a ~450 foot tall launch tower with a crane that stacks a Starship onto a Booster while the Booster is already in the launch mounts, leans back 30 degrees during launch, sits there for ten minutes until the Booster comes back and lands right back where it started, then hauls itself back to vertical using a bank of electric hydraulic pumps powered by tesla motors, locks itself into place with some beefy steel pins, and gets prepped to stack the next Starship waiting in line.
