You’ll find similar physics research for example in nuclear power, optics, quantum computers, telecommunications, engines.. all kinds of engineering really. Chemistry is also quite relevant and there are new, stronger materials being engineered all the time based on research.
It’s definitely not all just 1900s physics driving everything, even if you say that for some reason anything researched then doesn’t fall under the 80% of science that doesn’t work (which GP didn’t).
Much of what you think of as science came from engineers.
GPS relies very little on 20th century science, beyond GR corrections.
The science behind orbital mechanics is just Newton's Laws, stuff thoroughly settled centuries ago.
