if only it was possible...

“3 launches a day” is rather reasonable if you assume SpaceX has multiple launch pads. If they have Boca, LC-39A, LC-49.1, LC-49.2, and two floating platforms, that’s just one launch every other day from each platform. Faster than today, but entirely doable in the next 10 years.

>>14615054
Starlink is finished, it's time to de-orbit and go home.

I’ve been thinking about what if rockets were girls trying to compete in a beauty pageant.

>Starship and Superheavy
They’re the adoptive Texas-born twins of the Falcon family. Both are tall and pale with striking silver hair. Starship likes to dye her bangs black. Starship has a more muscular build despite being a foot shorter than her sister, too.
Both sisters have a witty and pioneering spirit. Neither are afraid of failure, and their down-to-earth mindset makes them incredibly popular online.

>The Falcon Family
A set of siblings and cousins who made waves in the beauty contest scene 10 years ago when they shook up the competition.
Falcon 1 is petite and shy. She never had much of a career but she inspired her other siblings to continue. Falcon 9 and Falcon Heavy are almost identical, although Heavy is a bit on the chubby side. All three of them are pale with long blond hair, although 9 and Heavy are noticeably very tall and slender.
Block 5 is the newest in the family. She actually has olive skin and jet black hair. Unlike her sisters, she’s the only one that still competes, although she hopes her adoptive daughters Starship and Superheavy will one day take her crown.

>SLS
SLS is the daughter of the previous champion, Space Shuttle. While she looks an awful lot like her mother, she is certainly much taller.
SLS is beautiful but some are off-put by her orange spray tan, which some chastise as looking like an old fad from the 80’s. SLS is adamant she took the orange spray tan advice from her mother.
SLS is conniving and arrogant. Although she knows Starship and Superheavy are more beautiful than her, many of the contest organizers are familiar with SLS’ family, and are willing to take bribes to sway their judgement. SLS doesn’t care if she cheats, so long as she wins.

I worked for a place that was trying to do a mobile satellite streaming service, over ten years ago. It tried to catch streamed MP3 files from a GEOsat. If it got an entire file, it saved it in flash for later play. It seemed like it would work pretty well as long as you stayed above ground most of the time. The whole plan collapsed when the parent company spent too much on useless crap and they had to cancel it.
They made a 16-element patch antenna for a car roof, and the PhD guy had all sorts of FPGA and software magic to make it work. I'll bet he's been getting patent royalties from Starlink.

What they told me was that they had wanted to buy chips to do it, but everything was priced for government contracts, not for consumer stuff, so they had to use fucking magic instead. I'm only partly surprised that a $16K satellite antenna is still a thing.

Kino

>>14615175
True but Starship blows it out of the water. Doesn’t really matter though. It’s a damn shame NASA never at least built one operation VTVL orbital rocket in its history.

Lately bro’s, I’ve been obsessed with the original shuttle design. It was called the DC-3. Fully reusable and it wasn’t even dolphin-sex based. NASA was actually pretty conservative with the design. It only put 5 tons into LEO, and NASA expected “only” 30 flights per year. It also was expected to cost about $100 million per launch, however, if carrying a crew of 7 like our shuttle, it would actually be even cheaper per person than any other manned vehicle.

I don’t know the utility of such a vehicle other than crew and cargo transport to space stations. But how would you even build a station? Most of the ISS modules are 20 tons or so. The shuttle in our timeline could put almost 6X the payload as the DC-3 into LEO. The DC-3 was fully reusable though, so it was probably a much better (and cheaper) crew transport.

In the world of the DC-3, expendable rockets like the Titan would build space stations, while the DC-3 would bring cargo and crew on a biweekly basis.

Can you force them to give you Starlink prices with their "best price guarantee" or is it essentially meaningless? (i.e. we'll give you the best price unless we decide not to sell you service at that price)

>>14615246
Who else actually has spare capacity besides SpaceX who is their direct competitor.

It's not like they were given 1.2 billion in advance, OneWeb has nothing to lose in this instance.

>>14615304
I'm sure they wanted to give money to SpaceX too, but they probably don't have any spare capacity to sell them.

>>14615308
I’m sure SpaceX would make it work if they were paid enough. Amazon probably doesn’t want to support a competitor.

>>14615426
if they were willing to blow enough money on it then it could've been done but if it got chosen for the x-33 then it would've ended much the same, with nasa killing it when they realized just how long and expensive the development was actually going to be

>>14615435
DC-X was a suborbital and subscale vehicle. It didn’t even use the same engine or tank structure as the full-size Delta Clipper SSTO. It’s like if SpaceX made a Methalox hopper the size of Dragon using a not-Raptor, then moved on to fill size Starship.

Also here’s the Delta V data for Delta Clipper.
>36 tons Dry
>434 tons of LH2/LOX
>425 second isp
>4.5 ton payload to LEO

Also NASA considered doing an intermediate vehicle between DC-X and full size Delta Clipper. It would’ve been half-size of the final product and actually use the same carbon fiber test tank. Think of it like the X-33 was for the Venturestar. The Delta Clipper program was doomed because of the SSTO thing anyways.

>>14614580
Get help. Stay away from our children.

>>14615426
>>14615452
Delta Clipper data source
>http://www.astronautix.com/d/deltaclipper.html

Also the entire vehicle was supposed to mass 36 tons dry and hold 440 tons of propellant. How the fuck? It literally had tanks sitting inside a shell. And TPS on one half. Crazy. I still think if a Delta Clipper was stacked on top of another one it could’ve worked though.

Here’s the inside of the DC-X test vehicle.

>Also NASA considered doing an intermediate vehicle between DC-X and full size Delta Clipper. It would’ve been half-size of the final product and actually use the same carbon fiber test tank. Think of it like the X-33 was for the Venturestar.
it literally was the x-33. delta clipper was mcdonnell douglas's entry into the competition alongside venturestar and rockwell's shuttle-looking contraption. there's a bit of an internet circlejerk about how nasa conspired to kill dc-x but there was no point in continuing to fund a testbed for a rocket that was never going to get built after venturestar won.

EARTHER (derogatory)

>>14615472
I think Delta Clipper could’ve been salvaged if it was changed into a semi-reusable vehicle like Falcon 9. Or maybe a smaller starship clone.

>>14615452
That mass ratio is 1/4th of the DC-X prototype, half that of the Saturn V, about equal to the S-IVB stage, only it has to be reusable and the T/W must be higher. It simply wasn't achievable without even higher Isp engines.

>>14615476
sure, but you could have just as easily done that with venturestar. that seems to have been the direction lockheed was moving in during the program's dying days.

>>14615342
pooGODs will win

>>14615481
SSTO is such a meme goddamnit. Even the S-II stage on the Saturn V had a mass of 27 tons without engines and held 440 tons of prop. Maybe you could get down to 20 if you made it balloon style or something. But the extra skin, TPS, and landing stuff? No chance it’s under 40 tons.

>>14615483
Thank God for SpaceX. I don’t think reusable rockets would’ve ever “worked” without private spaceflight

>>14615488
Whats the design choice behind those?

How are we going to deal with the different physiology of Martians Vs everybody else?
Will Martians be able to acclimatise to 1G?
Will there be a standardised spin gravity in space (IE 0.5G, 0.3G?) or will martians get BTFO every time they go to the earther station?

>>14615503
Martians would need to Martian gravity and space gravity.

Trade between the two will happen from LEO -> LMO. Only diplomats would need to work acclimate to each other's gravity, even then, these meetings could simply take place on LEO or LMO.

EPA? More like EPGay.

>>14615503
Whatever one rev per hour is based on the size of the ring, I think that's what we were talking about last time centrifugal spin got brought up

>>14615492
even x-33 was a rough attempt at privatizing things with nasa trying to make sure the companies could secure commercial backing and taking private demand into consideration when laying out their specifications. thankfully mike griffin realized the much easier way of going about things was to just deal with launch contracts and let the companies worry about how to design their rockets themselves.

No idea where this is from exactly but NASA figured that making Saturn V reusable would let it put 50 tons into LEO.

>>14615503
>will martians get BTFO every time they go to the earther station?
yes lmao

Yes electric propulsion is 'slow' in that its thrust is low, it makes up for it by being able to run continuously for days/weeks, making it the most capable propulsion method we have for long duration missions. Newer NASA concepts include a high thrust chemical stage to push the craft out of places where gravity losses would offset the extremely high ISP.

I did fuck up the math from being too drunk but it doesn't change anything. The delta-v increase from not being able to do the injection burn in LEO isn't actually that great and the performance of pure electric propulsion could probably beat a hybrid to any outer planet, especially if the probe was first injected to just inside Earth's SOI. The issue I have is with electric propulsion is confined to manned Mars transits, like what was proposed here (>>14615699) where the acceleration is just too damn slow to be useful compared to chemical which can do a conjunction transfer as little as three months. A hybrid in that instance would combine most of the downsides of both, especially considering that the crew cannot spend much time in the Van Allen belts so the time it takes to spiral out should be discounted as they would be loaded on afterwards.

>>14616090
Shut the fuck up. I would cancel the program due to being a spaceplane.

>>14615919
>>14615994
There's also the possibly of a SEP/chemical outer planet mission which initially would have much better acceleration than NEP before dropping significantly from inverse square law. In that case the chemical propulsion would just be used to capture around the planet. It would certainly be much cheaper, the downside is that the instruments wouldn't get nearly as much power once at the destination.

>>14615503
It's hard to say because we only know the long term effects of Earth gravity and microgravity, but nowhere in between.

>>14616090
I'd put the shuttle on top of a rocket

It's funny in hindsight that the whole reason the shuttle stack was designed the way it was to reuse the RS-25s now that the SLS is just going to throw them in the ocean

>>14616090
>If you were in charge of shuttle development in 1968, what would you change?
The shuttle that was made was the only one possible given the circumstances of the time. If we can handwave all political and budgetary concerns then just do the Integrated Program Plan verbatim with the Shuttle being nothing more than crew transport for a large space station
>For All Mankind and 2001 have me kind of obsessed with Shuttlecore.

What the fuck would you need to put into space that requires this much thrust?

>>14616163
Not enough to be worth it versus just launching three regular Starships.

The only reason "heavy" launch vehicles were popular is a way to bootstrap cheap expendable launches together because there was no simple two-stage rocket big enough to put a large satellite into orbit. When you have 100t+ to throw around you have so much leeway that you can build almost anything into one launch and in the rare occasion you can't the launches are so cheap that you could easily have margins to add docking hardware and/or refueling flights to build out something truly massive.

>The core idea behind the spacecoach architecture is the use of water, and potentially waste streams, as propellant in electric engines. Water, life support and consumables are critical elements in a long duration mission, and in a conventional ship, are dead weight that must be pushed around by propellant that cannot be used for other purposes. Water in a spacecoach, on the other hand, can be used for many things before it is reclaimed and sent to the engines, and it can be treated as working mass. This, combined with the increased propellant efficiency of electric engines, leads to a virtuous cycle that results in dramatic cost reductions compared to conventional ships while increasing mission capabilities. Cost reductions of one or two orders of magnitude, which would make travel to destinations throughout the inner solar system routine, are possible with this approach.

>>14616188
Why not?

Why are proposed space suits always human sized. Doesn't it actually get easier to design if you actually increase the size? The gravity is lower on almost every other world. You could go 2x or 3x the size without losing much but gaining great capabilities.

Even out in space why limit yourself. Instead dock it, and around a module build some arms and some legs, well in space some arms would do. Those VR cunts could get pretty close with haptic feedback these days + surgery can be done remotely. Mechs for combat are gay. But a mechs for human activity seem to make dramatically more sense.

PWRs have low operating temperature (~300C) so they need a shit ton of radiators and they have lower power conversion efficiencies. They're also high pressure so the hoop stress means a thick, heavy reactor vessel. Space-bound fission reactors need to be high temperature, and for anything larger than a microreactor, that means something like liquid metal, molten salt, or gas cooled reactors.

I'm not sold on water propellent for interplanetary spacecraft over higher performing alternatives, but for operation within a gravity well it's hard to beat. Water based MET is low cost, it has more thrust than most other types of electric propulsion, twice the Isp over chemical which enables a much greater payload, and since water is basically a low pressure non-toxic storable its very easy to integrate with a launch vehicle. That last part is a bigger deal than you might think, SpaceX literally banned Spaceflight Inc. from future launches because they had a leak on a rideshare mission.

You could use it to refuel a depot at EML-2 which would be a great departing point for outgoing low thrust spacecraft or chemical spacecraft that want to save ~3 km/s over departing in LEO.

Does it matter? NTSB head backs her. She's likely not the only one, but rather one of the few thats openly anti-Musk in public.
