>In solids and hybrids, the tank IS the chamber
yah i get that
>solids and pressure-fed liquids MUST have tanks above the chamber pressure.
yah i get that too

>STAR-48 remarkable mass ratio
still has shit isp

>Challenger's SRB didn't explode until the RSO hit the self-destruct button.
If you believe this you really need to have your head examined.

>And liquids DO explode, contrary to your assertion.
An engine failure on a modern liquid rocket does not cause the thing to explode. Firstly the fuel and oxygen are not in the same place, they cant burn when they are separated. Secondly if an engine fails in a non explosive manor you can turn it off. If an engine explodes there is usually shielding to protect the rest of the rocket. Properly designed liquids inherently fail safe, solids unavoidably fail catastrophically. As for Soyuz T-10a another key component was the remarkable amount of time they had before before aborting, where a solid failing there may be no warning. Yes liquids do explode, when they hit the ground, when an rso presses the button, or when tanks structurally fail, or when monopropellents are used.

>Composite materials performance at cryogenic temps is sketchy territory.
Not like I'm proposing hydrogen slush, I think LNG would make a fine fuel but if cryos are an issue kerosene(or another liquid hydrocarbon) and N2O4 could always be used instead.

>Your ISP will suffer
I know, I still think it would be superior to solids. You can always feed it but I wanted to keep things simple. A smaller feed tank of liquid helium, a (decomposition) gas generator or if you're using mild cryos you can use a heat exchanger and boil some of it.

Scientific journals were a godsend back in 1666.
Before them discoveries would be made, hidden encrypted and repeatedly lost.

The model is old and decayed it's corrupted by biases, fraud, laziness and elitism. It needs to go the way of the dodo bird. All publicly funded science should be 'published' in a model more like open source software.

Nice get, in pony thread too.

Why do I always get banned from all boards? That's just inane.

Hey I'm on there (^_^) I was the one about the zygote question. We had a good thread going too bad the mod had to fuck it all up.

But does anyone know if an egg that comes out during the period is still viable?
