    The rocket motor of the future “breathes” air like a jet engine.

    At last it mentions the SABRE.

    So what happens when there isn't any air to breathe?

    I think you are looking at a weapon, not a vehicle for space exploration. The weapon can stay in the atmosphere while it rushes supersonically to its target half the globe away. But if you point your air-breathing rocket straight up, it's gonna sphixiate pretty quick.

    I expect if it works it would carry oxygen tanks as well.

    Wut? You go to all that trouble so the rocket doesn't have to lift its own oxidiser and then you stick it on anyway? It's like putting water tanks on a fish.

    It still helps as you know liquid oxygen is a lot heavier than liquid hydrogen for the same volume if you can reduce that by 20% you can put more payload into orbit.

    Like the article, I posted above states it is unproven so far.

    It could make a cheap weapon or supersonic plane if it works.

    It's nothing to do with me. It's that Noah and his newfangled "Ark".

    It was a frog-choking gully-washer for certain.

    Noah was a weird one. God told him to build a boat because it was going to rain. We all laughed. He tried building it out of stainless steel but it kept blowing up. Then his kid Japheth told him to build it out of gopher wood and that seemed to work OK. I never saw any gopher trees around here, but who knows?

    It actually did rain for forty days and nights, go figure, and it was a real frog-choker as al says. Damn near broke the levee. Anyway, off drifts Noah and family, and a shitload of pets - I told you he was weird. Giraffes and boa constrictors and rheas and platypuses. The feed bill must have been enormous. Eventually he drifts back to civilisation and the Egyptians capture the family and enslave them until Moses appears, but that's another story.

    But that kid Japheth was a bad seed. He started Europe, and then America, and Capitalism and Atomic Bombs and who knows what all. Even the interwebs. We sorta wish they had stuck with the stainless steel.

    Mars's history is uncannily similar to Earth's.
