The strongest evidence says NASA still advances science more than private companies, because science means peer-reviewed discoveries, not just cheaper rockets. My opponent can point to lower launch costs and faster iteration, and that's fair. But those gains build on decades of NASA research and funding. Private firms keep data and methods proprietary; NASA publishes openly, funds basic physics, astronomy, and Earth science, and lets thousands of researchers build on results. If you can't replicate it or read it, it's engineering, not science. That's why NASA remains the stronger engine.
