The Space Shuttle was "America's Ride To Space" for 3 decades, it launched over 100 times, and yet over that long career it only launched 3 interplanetary missions - Magellan, Galileo and Ulysses. And all of those were launched in 2 years, after that everything the Shuttle carried remained in Earth orbit.
Multiple factors came together to limit this:
- The Shuttle was late and expensive
- The Reagan administration cancelled most interplanetary missions
- Challenger's destruction changed NASA's policy requiring all launches on shuttle.
