The planetary science division of the space program accomplishes extraordinary things, because it is extraordinary. We want to look for signs of life on other worlds, places like Jupiter’s moon Europa and Saturn’s moon Enceladus. That work is done by our planetary explorers, scientists and engineers, who really are seeking signs of life on another world. Such a discovery would be astounding. It would, as so many astronomical discoveries have, change the course of human history.
Planetary exploration not only brings us astonishing discoveries from other worlds, it inherently leads to innovation, because we invest in solving problems which have never been solved before. That in turn creates new businesses and economic growth. But more importantly, supporting a robust space program raises everyone’s expectation of what’s possible. With a space program, everyone in our society comes to believe and expect that any problem we face can be solved. It’s inherently optimistic.”
