RD-172 (what was planned for Vulkan, and what RD-191 was derived from): 784 tons SL thrust in a 3.56m diameter circle = 78.76t/m2 (base RD-171 = 5% lower), that's between F9 (72t/m2) and Superheavy (99t/m2, considering nozzles stick out slightly from the 9m diameter)
For the time, it was good,
I agree the calculation change when you aim for reuse, but from the soviet's point of view, RD-171 was a clear improvement compared to the NK-15 and NK-33

I feel like birds would be kino pets for low/0 g environments. They're already capable of 3d movement so they might adapt well. And seeing them hover with like half the wing flaprate they have on earth would be super trippy.
That's also why cats are objectively better space pets than dogs, they're way more vertical.

> On January 5th, NASA announced that the agency will increase its investment in next generation space stations by $99.5 million, in another step towards Low Earth Orbit (LEO) commercialization. Blue Origin and Voyager Space, along with Axiom Space are NASA’s primary partners in developing commercially owned and operated space stations that will succeed the International Space Station (ISS) as early as 2030.
>Blue Origin will receive an additional $42 million, bringing the total award for Orbital Reef space station development to $172 million, while Voyager Space will receive an additional $57.5 million, bringing the total award for Starlab development to $217.5 million. With the adjustments to these contracts, NASA has introduced new technical milestones aimed at expediting development, mitigating risks, and enhancing NASA's understanding of station design and progress.

> NASA’s other funded commercial station partner is Axiom Space. Notably, Axiom’s architecture involves attaching their first modules to the ISS. In addition to the increase for Blue Origin and Voyager Space, NASA is negotiating additional content for Axiom’s contract.
>How does Gravitics fit into NASA’s Commercial LEO Development program? Gravitics is positioned to provide NASA’s partners and the rest of the industry with the most valuable next-generation space station modules. Gravitics is wholly focused on establishing the vital capability to manufacture, integrate, test, qualify, and deliver large space structures and components at a rapid pace.
>NASA has additional agreements that support commercial space destination efforts, including Sierra Space, Vast Space, Northrop Grumman and others. NASA's strategy aims to have commercial stations operational in the late 2020s and the agency’s continued investment in commercial space stations is a progressive advancement toward a thriving future of commercial destinations in Low Earth Orbit. #SpaceStationSaturday

I can play this game with Artemis II too
A. First launch of Orion and SLS with crew
B. First flight test of Orion ECLSS with crew
C. First human spaceflight launch from LC-39B since STS-116
D. First potential use of LC-39B Emergency Pad Abort baskets
E. First in space approach and maneuvers of Orion in proximity with another space vehicle (ICPS)
F. First operational use of the Orion Crew Survival System (OCSS) IVA suit.
G. First NASA crewed TLI burn in 50+ years
H. First woman sent to deep space
I. First use of Orion communications and O2O system between NASA and crew
J. First crewed flyby of the Moon in 50 years
K. First reentry of Orion with crew onboard
L. First test of newly revised heat shield
M. First test of Orion parachute deploy with crew
N. First test of Orion/NASA/US Navy recovery efforts and procedures
As you can see Artemis II includes a lot of "firsts" that the panel is concerned about, many of which must be demonstrated sequentially and prior to lift-off and many of which must be demonstrated upon reentry and will be first demonstrated on the first crewed mission of the first deep space capsule since the first one (Apollo CSM) 50 years ago which landed the first men on the Moon.

> SpaceX, though, did have to make changes to accommodate Cygnus, specifically its ability for “late load” of cargo within 24 hours of launch. The Antares has a “pop top” opening at the top of the rocket’s payload fairing, allowing access to the Cygnus inside for cargo loading after the spacecraft has been encapsulated.
>To provide a similar late load capability for Falcon 9 launches of Cygnus, SpaceX created what Bill Gerstenmaier, vice president of build and flight reliability at SpaceX, called a “gigadoor” in the fairing of the Falcon 9. That is a door 1.5 by 1.2 meters in the side of the fairing that can be opened to provide environmentally controlled access to the Cygnus inside.

also a common mistake people seem to make is that technology just somehow appears out of thin air
it doesn't, people need to develop it and it doesn't get developed if there is no incentive to do so
going to space is going to incentivize developing better propulsion methods which will ultimately make propulsion better in space
you have to ride the technology cost curve down
without batteries in laptops, there would be no batteries in electric cars because it would be too expensive of a leap to go directly to electric cars

You don't need FTL to settle anything within, say, a radius of 50 light years of Earth if you have tech that allows a significant fraction of light speed.
Not even talking about cryo tech and generation ships (not like dozens of generations, but imagine like two generations) here.
Within a sphere of 100ly there are hundreds to thousands of star systems.

>justify this
there really is no justifying it. a full stack holds 1200 tons of fuel. starship carries 150 tons to orbit, so the actual number of launches should be 8. Future starships are going to aim for 200 tons to orbit, which will make it 6 launches. If they stretch starship that could take the cargo to orbit up to 250-300 tons, which would reduce the number of flights needed to 5 or 4 respectively
for it to require 16 starship flights to fuel a starship, it would have to be pulling half of it's payload capacity, 75 tons. there's no reason that they should put such little transfer fuel on board

So what’s the final call? Why didn't NASA go with even a partially reusable SLS rocket? Why did they choose to go the “oldspace” route?
Because expendable is not out of date. It completely depends on what the objective in the program is.
For SLS, its accessing high energy orbital planes and beyond with only one launch. It accomplishes that by eliminating the need for heavy heat shields, spare fuel, or guidance computers that would just be dead weight required for it to survive reentry. Every spare ounce of weight was put into getting as much payload as possible in one launch.

Pyrios booster cancellation was basically an admission that they couldn't do RP-1 engines like the Soviets.
Remember the F-1A and F-1B are not exactly the same as the Rocketdyne F-1, they're actually closer to a clean sheet design - and they weren't very good despite solving the combustion instability problem...
This basically meant that they had to stick with the Space Shuttle solids.
The other candidate they had in mind was... a Delta IV Heavy with 7 cores.
So yeah, out of a clusterfuck of choices SLS was indeed the best option.

The most important thing other then technology is a consistent plan.

No. Also, most of the problem isn't in the fact that the fuel is absurdly explosive; it's the toxic chemical residue it'll leave all over everything after ii gets done exploding. This is still a problem if it explodes normally to produce thrust.

1. Mass produce it. Cost goes down with economies of scale (Deep Space Transport LLC)
2. ICPS needs to go. J-2X EUS with ACES tech or nothing. Centaur/ICPS could be the third stage.
3. RS-25s need to go. Rocketdyne still has those RD-0120s (aka expendable SSMEs) in storage?
4. Replace SRBs w/ Castor 1200s.
SLS fills a niche in the launch market no other rocket can.
SLS has a clear advantage in the high energy orbital plane due to its insane efficiency using hydrolox, coupled with safety and precision.
We must keep flying SLS if we are to earn back what we invested.
Starship, frankly, does not compete with SLS for the applications they are built for.
Does Starship get higher to LEO? Yes, but they're not built to go to LEO.
SLS wins out by having an incredible efficiency, 366 sec at launch, 452 in space, and 468 in S2.
Starship? 330 at launch and (a goal of) 380 in space.
For an idea of how badly this affects a rocket, have a look at this graph provided by NASA LSP comparing Delta IV Heavy to Falcon Heavy.
Remember that FH launches significantly more to LEO than DIVH.
12 is the energy to get to Mars, 80 is to Jupiter. Saturn and Uranus need ~147 direct, and Parker Solar Probe needed 108.
Even Atlas V 551 beats Falcon Heavy to Mars.
While Expendable FH beats Delta IVH most of the way - based on extrapolation, DIVH wins for outer solar system.
SLS can do 10 Parker Solar Probes.

A good thought, but SLS isn't designed for that, probably intentionally
>ICPS/EUS
DCSS-5 is fine if you use it as a third stage, and not just because it'd be easy to replace with a Centaur V as an upgrade. The real issue is how heavy and poorly designed the SLS core is. It should be two stages instead of one.
>RD-0120s
The RS-25E is fine for everything except price. Instead of handing some no competition contract to AJR there should have been a main engine competition and Blue Origin should have submitted a SSME equivilant bid. They probably wouldn't have won, but it would have been good leverage to keep aerojet honest. Suggesting using Russia engines that haven't been produced since the late eighties is dumb and you should feel dumb.
>We must keep flying SLS if we are to earn back what we invested.
Sunk cost fallacy. "We must keep providing Boeing with corporate welfare to justify all of the previous corporate welfare" is not a good argument.
>SLS wins out by having an incredible efficiency
One launch per year for $4.5 billion is not efficient. Focus on building the rocket factory as much as the rocket.
>Falcon Heavy/Delta IV Heavy
Delta IV was so cost inefficient not even ULA wanted to keep it around. Falcon Heavy has become the de facto launcher for all NASA outer planets missions.

>Broadly accepted physics says that you can produce thrust without ejecting propellant, using a “photon” drive. For instance a flashlight produces a bit of thrust. The reason NASA/SpaceX/etc. have never created a photon drive is that it takes an enormous amount of energy to produce a small amount of thrust. IVO claims their drive can produce 52 millinewtons with one watt. Standard physics says that a 52 millinewton photon drive would require – 15 megawatts.

I hate horizontal takeoff orbital vehicles so much.
The whole idea of horizontal flight in a vehicle with enough propellant to achieve orbital velocity is so stupid.
NASP had to achieve Mach 25 on scramjets in order to make any kind of sense (no this wasn't feasible).
And it would still probably be the most complex and expensive aircraft in history and deliver like 5 tons to orbit.
Just incredible what people will look over to have a cool space plane or 'airport operations', this shit makes the X-33 look extremely reasonable.

Vthl is fine although honestly if a vertical landing is possible you might as well, little benefit anymore to horizontal landing; even if you want an orbiter with high cross range it's still better to land vertically to ease re-integration and to simplify landing legs, only downside is requiring a restartable/throttle able engine.

VTHL is a lot like hydrogen first stages. It's not the most attractive overall, but if you've already got a lot of investment into the prerequisites it can be more economical than pursuing something like VTVL from scratch.

If SLS is a jobs program its one of the most successful jobs programs ever. Congress is more than happy to fund programs like SLS. The reason being is that those programs generate an insane amount of economic return for their constituents (>3x return on investment).
But all of that is irrelevant.
The USG is likely to keep SLS even when Starship is up and running because it wants to retain a critical national capability.

Also i want to add the NRO is being very coy about its desire to use SLS...
while their spokeswoman said they have 'no interest' in the rocket because its 'solid motors will damage the sensitive instruments on our satellites', it seems they actually are interested in using it.
They've been in talks about it with NASA for a while.
The MSFC center director even mentioned it at an all hands meeting after Artemis I.
My best guess is they are working on some kind of spacecraft that uses a very eccentric beyond-geostationary orbit beyond the reach of Chinese surface to GEO and GEO to GEO ASAT.
They would ideally like to launch this thing before the 2030s.

then you also need the facilities to prepare the food; knives, pans, pots, salt, yeast etc.

does your car need to match the speed of the airplane mid-air while you board it? dumbass

would you rather get a small capsule up to mars transfer speed, or a space station big enough for several people to spend months in it?
obviously you save resources not launching your transfer vehicle every time. fuck you

At this point large nuclear power sources are the only remaining potential payloads for a Cargo SLS.

Starship makes this argument moot. Capsules will not be involved in any interplanetary crew missions. We will go inside huge spacecraft with comfy habitats and large excess mass budgets, and it will be based.

You dont save shit, you waste loads of delta-v to get your monkey ass to the cycler. Your gay architecture requires high energy transport to and from the cycler. You could do it with expendable rockets, I'm sure that would be affordable. Thanks, Buzz

Based on what? Physics?

Correct.
The minimum sized cycler that makes any sense at all is a literal full scale Bernal Sphere or equivalent orbital. Anything less than totally self sufficient means the cycler will require more launched mass per cycle to maintain than you'd need to simply launch Starships to Mars.
Remember the original concept of a cycler was born out of trying to figure out a Mars mission campaign of ~5 to 10 missions total using Apollo era tech, such as the literal Apollo capsule and Saturn V rockets. It's a solution to a problem that no longer exists using hardware that hasn't flown for over half a century.

Based on the fact that the paradigm under which cyclers were conceived as potentially useful no longer exists. It's over, unironically, for the cycler concept. We do not need it, for the same reason we do not need the pony express.

We will build the Aldrin Starship cycler, we will build several, and you WILL use them

The beauty of the Starship cycler is that it doubles as a habitat on Mars, it can be used more often than a traditional cycler because it doesn't swing out into the asteroid belt on a long trajectory, and it even gets inspected for reuse on the ground on Earth!
>disclaimer, starship cycler is just starship going to land on Mars and coming back

makes sense if you have a vehicle that doesn't need to conserve mass, momentum or energy
they should have visited other galaxies or gone back in time to kill Hitler
