Space exploration is the ultimate plan B. Here’s why.

Why did the dinosaurs go extinct? Because they didn't have a space program.

  • Space exploration is more than just the ultimate adventure, our study and investigation of space yields great scientific rewards, says astronaut Garrett Reisman.
  • Earth is wonderful, but it won't last forever, so it's important that we maintain a big picture view to ensure the survival of the human species.
  • Exploring space is our ticket to "the ultimate plan B," according to Reisman. If there were to occur a mass extinction event on Earth, the humans that inhabit another planet in our solar system will be the only hope of human survival.
