but yeah anyway wouldn't this kind of technology be the next step to like.. deep space exploration or has that already been discussed?
There is no way that scramjet technology can work properly outside of an Earth like atmosphere.
A shuttle rocket works because it carries large quantities of the one thing fire needs to exist... Oxygen.
A shuttle uses oxygen as a fuel source along with hydrogen, meaning that if you wanted to adapt the scramjet, you'd have to pump large quantities of oxygen into it mechanically, rather than just scooping it into the engines because you're going at stupidly high speeds.
Scramjet technology may be usable for getting off the ground, but there's much more viable technologies for providing thrust once you're in space.
