It looks nice. Yes, old STSs were good for repair satellite, etc. STSs are almost same idea like semi-truck with trailer for heavy load but very expensive for fuel, carry, etc. Next Generation Space Shuttle is much cheaper and probably more travel to spaces.
I just hope to see this that NASA scientist designs faster-than-light spacecraft.
It's actually been around for awhile, it has flown one mission that lasted 675 days in space. So far it has flown unmanned. Two get a feel for it's size, you could fit two of them into a space shuttle cargo bay.
