Space exploration allows us to prove or disprove scientific theories developed on Earth. Studying the solar system, for example, has brought us insights into such phenomena as gravity, the magnetosphere, the atmosphere, fluid dynamics and the geological evolution of other planets.

Why space exploration is not important?

Space exploration gives us no direct benefit. The Earth itself is not fully explored yet. A commercial space industry is taking over. the new crisis on planet earth: finish your priorities before starting new ones.

Is space exploration really worth?

Manned space exploration is absolutely worth the investment. It's not just about what we learn out there in space, or about ourselves, or how to be a better steward of precious Earth. It's about how we live here on Earth together and what type of future we want for ourselves and children.
