With that combo, you’ll likely get to orbit sooner than SLS ...

The F-1B was for the strap on boosters. NASA went with the stupid solid fuel boosters instead, just like the ones that blew up Challenger

Naahhh!

It does not self ignite, but smells great.

Hydrogen is extremely useful as a rocket fuel. It’s readily available, clean, lightweight, and, when combined with liquid oxygen, burns with extreme intensity.

Yes, and notoriously hard to contain.

I’m running on pure memory, here, so bear with me ...

They should have built the F-1B regardless of whether it was to power the core stage or the side boosters.

I’ve never liked the idea of solid rockets for manned spaceflight, even before Challenger.

Smells great?

Before: yes. I love the scent of roasting chiles, and anything cooked with them. Delicious.

After: We’ll not talk about that ...

I don’t notice the after affect.

Have got to the point I don’t care for Jalapenos. The taste of Habaneros is much better, but it must be handled carefully, smile.

NASA is sure that the application of great gobs of taxpayer dollars will solve problems as they arise.

LH2 is a fine fuel, widely used for decades without any real trouble.

It needs to be used where it's appropriate. You can't store it long term and it's thrust is lousy. Works great for a second stage where you need all the specific impulse to build speed but not so much thrust.

One thing the space shuttle should have taught is that parallel staging is downright dangerous. But using hydrogen to get off the ground forces you to do it, and use solids to make up for the inadequate thrust.

Uhhhh...
Because it was built by the low bidder

Hydrogen is not even a molecule, it’s an atom. It would have to be dihydrogen (H2) to be a molecule.

I think its funny that our most sophisticated manned space vehicle (the space shuttle) was (excluding the boosters) essentially steam powered.

Yes, the same thing has occurred to me. It's essentially a steam reaction engine, like that built by Hero of Alexandria. Except of course that it doesn't vaporize water by means of an external heat source, it actually makes the water with a strongly exothermic reaction, the heat of which serves to compress the steam that is the reaction product.

When I watch people mowing their lawn or using small gas engines for leaf blowers or string trimmers, I amuse myself by thinking that the fuel tank is actually a very efficient container for a compressed gas.

I try to picture the size a compressed air reservoir would have to be in order to run a leaf blower for an hour or so without a compressor to kick on and replenish it. This seems reasonable because a string trimmer engine has about the same power capacity as the compressed air motor in a hand-held grinder or impact wrench.

When I think of it that way, I realize that the tiny fuel tank in a string trimmer holds thousands of cubic feet of high pressure gas, but is itself tiny and is made of light, inexpensive plastic.

It makes me appreciate the value of the internal combustion engine.

built by lowest bidder contracts?


No that old school .. now it’s

built by contractors with the highest Diversity and ESG score

Hydrogen is racist. LOL.

Monomethylhydrazine (not simple hydrogen) and nitrogen tetroxide (powerful oxidizer) are the normal rocket fuels.

MMH/NTO are not used for main rocket engine propulsion but only for maneuvering and attitude control thrusters once on orbit. Occasionally also for upper stages and for small attitude control steering thrusters on some launch vehicles. Extremely nasty, poisonous, corrosive and hypergolic chemicals, meaning the two of them explode on contact.

What is normally understood as "Hydrogen" is H2, just as what is normally understood as "Oxygen" is O2.
