Saturn-Shuttle and reusing the tanks and other hardware for later flights). The Shuttle would handle space station logistics, while Saturn V would launch components. This would have allowed the International Space Station, using a Skylab or Mir configuration with both U.S. and Russian docking ports, to have been lifted with just a handful of launches. The Saturn-Shuttle concept also would have eliminated the Space Shuttle Solid Rocket Boosters that ultimately precipitated the Space Shuttle "Challenger" accident in 1986. Because the shuttle orbiter would be riding piggyback on the external tank, and the need to prevent damage to the delicate thermal protection
