Fun fact, the LR-87 on the Titan first stage does have derivatives that are fueled by kerolox, hydrolox, and hypergols. The hydrolox version (LR-87 LH2), went into competition against the J-2 for the Apollo program.

I'd imagine that for even a lot of nerds the sci fi aspects of space are more compelling than the real world history.

It wasn't until Falcon Heavy and getting way deeper into KSP that I actually started to really dive deep on how to design proper rockets, which led to Hullo and the like and eventually learning more about how things got to where they are.

If you aren't from the US keep in mind that American public school sucks dick, the history programs are generally wildly lacking and at least in my experience most history classes end either at the 20th century or after WWII.

New Glenn's real advantage is that it's going to be able to one-shot an Orion/Starliner-sized capsule into lunar orbit. I'd bet money on that capsule being the part of the setup that BO ISN'T talking about.

I'd also bet that it's going to be like Crew Dragon in that the fuel tanks and the crew areas will be in a single vehicle that re-enters as a single unit and lands propulsively, and that New Shepherd is low-key a testbed for using cryogenic hydrolox in re-startable engines on a spacecraft that lands propulsively. If they pull that off, then they have something that can pull off an Apollo 8/Zond-style mission while only expending the 2nd stage.

Starship is designed to fly big shit to LEO as Space Shuttle 2.0 that flies as a TSTO instead of a 1.5 stage booster-sustainer. Unlike the Space Shuttle, Starship can be refuelled on-orbit and once fully fueled, has enough delta-V to fly a trans-martian injection, Martian orbital capture, and re-entry/propulsive landing. Once on Mars, Starship has enough delta-V to fly as an SSTO in Martian gravity and fly a return injection to Earth.

Starship actually sucks as a lunar launch vehicle or a GEO/Lagrange access vehicle. New Glenn, OTOH is overpowered AF for manned access to LEO but its 3-stage design is perfect for manned access to GEO, the Moon, and the Lagrange points.

Raptor is the rocket engine equivalent of a BMW 3.0 liter inline 6 that uses direct injection, variable valve timing, and twin turbochargers to make 335hp.

It's the 6000 m/s per stage delta V rule. Two stages are perfect for LEO, but lunar orbit takes more delta V than than you can realistically get from a 2-stage design. That's why Starship can't get to the moon without refueling in LEO.

Now, the cost of multiple refueling flights make sense when you're talking about sending a payload to Mars, but the extra fuel needed to get to the moon is such that the cost of a F9 style expendable 2nd stage is honestly less than the cost of all those refueling flights needed to make a Starship-style TSTO go to the moon and back.

If you factor in cost/ton of payload, I'm pretty sure that a refueled Starship will still be considerably cheaper than anything with an expendable upper stage. Last I heard a Falcon upper stage alone was estimated to be somewhere in the $10 million range, so something destined for the moon would likely be at least 2-3x that. If Starship can hit its target of $2M per launch, that means that you can put up a Starship with 100 tons of cargo and refuel it for less than half the cost. Even if you go another series of flights to refuel it in lunar orbit, you'd still be looking at somewhere around the same price.

The cost savings of reusing the upper stage stack up absurdly quick, even more so when that upper stage can carry a shit ton of payload.

>> No.12064083

>>12064072
To clarify I mean that you can launch the payload starship, and then do the 5 or 6 refueling flights and it'll still be about half the cost of the expendable upper stage.

Also that upper stage cost is using SpaceX tier costs, who knows how much BO is spending to build their rockets considering how incestuous they are with old space. I wouldn't be all that shocked if their moon transfer vehicle cost $50M+.

>> No.12064106

NASA was unused to lengthy delays in its programs, and was under great pressure from the government and military to launch soon."
>"In March 1979 it moved the incomplete Columbia, with 7,800 of the 31,000 tiles missing, from the Rockwell International plant in Palmdale, California to Kennedy Space Center in Florida. Beyond creating the appearance of progress in the program, NASA hoped that the tiling could be finished while the rest of the orbiter was prepared."
>"This was a mistake; some of the Rockwell tilers disliked Florida and soon returned to California, and the Orbiter Processing Facility was not designed for manufacturing and was too small for its 400 workers."
>"Each tile used cement that required 16 hours to cure. After the tile was affixed to the cement, a jack held it in place for another 16 hours. In March 1979 it took each worker 40 hours to install one tile; by using young, efficient college students during the summer the pace sped up to 1.8 tiles per worker per week."

Fancy adhesives doesn't change the time required, and the tolerances needed shouldn't take 40 hours by any stretch of imagination. I could lay down any tile with any achievable tolerances you want in easily less than an hour and I suspect all these tiles were precut, preplanned and a grid already laid out on the hull for you to follow, so there was no real thought involved to their application.

I don't think so. A touch screen with a GUI doesn't really add to the cost of the flight computer.
I would be like controlling it from your phone, you can do it if you want but it is not needed.

Thinking about it more carefully, you probably would prefer to be in front of the control panel at all times, and have the control panel locked in a separate room, like in a air plane.
Someone could steal the phone or hijack one of the pilots. There would likely be a time interval between the hijacking and when the other pilot notices it and shuts off the wireless interface.
Having any kind of ship control communication through wireless sounds like asking for trouble. Now I think phone and neuralink are bad ideas.

No, Venture Star wouldn't have ever worked.
The original design called for a very optimistic wet-dry mass ratio which would require either aluminum balloon tanks or CFC nearly-balloon-tanks, as well as VERY optimistic engine performance metrics.
While working on the X-33, the subscale sub-orbital Venture Star technology pathfinder vehicle, it was discovered that CFC structures using technology and techniques of the time would actually turn out heavier than aluminum tanks, meaning that for Venture Star to work their only option would be aluminum balloon tanks (ie, it was not a feasible design).
Worse, the engines they developed for the X-33 weren't even close to the performance metrics necessary to make Venture Star work, not just in terms of thrust (since X-33 used a smaller engine than Venture Star needed), but in terms of Isp and TWR.
The fact that Venture Star required a wet-dry mass ratio beyond the capabilities of technology at the time, AND required propulsion far in advance of what could actually be built, meant that it would NEVER have worked.
The metallic TPS was the best thing to come out of the program. It would have helped Shuttle, but more importantly it would have been useful on a reusable TSTO launch vehicle based off of the DC-X design (vertical takeoff, vertical landing, sideways reentry).

Do y’all think Scott Manley learned 99% of his rocket knowledge recently? Or has he known most of this stuff since his college days or something. Yeah he can be intolerable on twitter, but the man has a knowledge of rockets and space programs that exceeds the typical “I just google stuff and make videos about elon musks tweets”. I think i’ve learned 99% of what I know just from him

Astronomy, specifically astrophysics. He either minored in programming or its a big time hobby for him because IIRC for his thesis he programmed a map of all the known asteroids in the solar system and it was so good even NASA uses it all the time. And now he does programming for Apple (explains why he’s a califag)
