Interestingly, from what I could find, those WERE supposed to be methalox after some iterations. The boosters' engines would be a modified RD-170 (known as the RD-17X), and the boosters would be recovered and flyback after every launch.

I have some more art. Pic related.

More like it's been almost 50 years since the last push to the moon and NASA is pulling all the stops to get as much political support behind it as possible so that when (not if, when) the next Democrat president comes along he won't trash the whole thing simply because a Republican started the whole mission.

It also has an abort system. Not sure how effective it is compared to a capsule on top of a stack, but at least it's something. Also the SRB o-rings work fine if their operating conditions are respected. Challenger wasn't due to the o-rings failing, it was due to management knowing that the o-rings were compromised and decided to launch anyways. Like I said before, shit management can kill any project.

Because muh ICBMs, can't spend money to keep the SRB engineers employed working on ICBMs because of treaties, so find a way to use them in the manned spaceflight budget to keep them employed.

>>10648313
And the abort system is integral, unlike all the oldspace rocket-on-top designs. Only now that reusability is a thing is it getting into non-paper spacecraft.

But look at the drawing, there seems to be literally no space outside of the 10 seats. Shuttle was cramped enough with 7 crew and two decks. Good luck doing experiments without loading up a space lab module. I'm not even sure where they planned to put the EVA airlock. And I'm going to assume that they figured out a way to have crew access to a space lab module that works with the abort system.

That's a very complicated issue of NASA, but it's not due to NASA not wanting to do anything. It's mostly due to Congress not wanting to do anything, and every president since Kennedy wanting their own pet project while canceling their predecessor's. I know that the spaceflight scene seems depressing with nothing happening in the 50 years since Apollo, but things are appearing to get better with the rise of China and private space companies, and NASA finally getting some hardware to go beyond Earth orbit.

The memo argued that the legislation would endanger the national airspace by helping to increase the frequency of launches. DeFazio also made his animosity toward commercial human spaceflight known in later interviews. “I’m not going to inconvenience hundreds of thousands of people so some rich person who can pay $250,000 to be weightless for six minutes can have a fun day,” DeFazio told Politico. “They can go at 3 o’clock in the morning from a remote area.”

No, you are wrong.
An SSTO loses efficiency precisely because it does not stage which means it has to drag all of it's mass to orbit all the way using one propulsion system. A staged rocket can also equip an aerospike engine and benefit from the same propulsion efficiency increases while also losing all of the weight of it's expended tanks.

Hydrazine is irrelevant for high performance stages, it is used for things like thrusters and such.

As for RP-1, it has its own disadvantages, namely rather low specific impulse, not burning very cleanly which leads to coking in the engine and is bad for reusability, and being much harder to make from in situ resources in space.

Methane is really the sweet spot.
