NASA art, circa 1975, depicting the Space Transportation System. Apart from the paint job, this is pretty much as-flown, except for the fairing over the nose of the ET.  This probably depicts the “de-orbit” solid rocket motor that early ET concepts showed, meant to make sure that the ET was properly dumped into the Indian Ocean.

A NASA painting of a 1969-vintage Space Shuttle concept. This was known as the “DC-3” configuration, and was designed – or at least heavily pushed – by Maxime Faget, and was adopted by several McDonnell-Douglas designs. It featured two manned and reusable rocket powered stages, both burning hydrogen & oxygen, both with straight wings. The smaller orbiter would basically “belly flop” into the atmosphere when re-entering. The straight wings would not provide a whole lot of lift, but they would also not be very massive. Thus the vehicles were relatively lightweight, but with restricted crossrange. Both stages also had turbofan engines mounted in the nose for cruise and landing assist.

A closeup of part of the “wheel” of the early-60’s Lockheed space station concept. Via NASA history office.

A number of early rotating space stations used “wheels” like this, with straight cylindrical segments forming a torus. While this would be relatively easy to build, it would have the result that the flat floors would be “curved” from the standpoint of “gravity.” Things would roll “downhill” towards the joints between segments.
