Let’s remember that public money spent on space exploration has been a consistently excellent investment for humans everywhere.
First aid blankets. Firefighters’ radios. Practical freeze-drying. Countless solar power breakthroughs.
Techniques for high-reliability software development. Lifetime component tracking. Error-correcting radios like cell phones use.
But tech spinoffs are only part of it. Exploration itself is valuable because it gets us thinking in new ways.
Looking at Mars or Titan isn’t only about Mars and Titan. It’s about us. Planetary science is a way to understand ourselves.
