Jim Garvin Quotes on Astronomy & Cosmology (2 Quotes)

Earth is the laboratory for future discoveries on Mars. Without examining Earth's extreme environments, we wouldn't understand how processes worked to shape the landscape, chemistry and life at the limits. Without that understanding, we couldn't draw conclusions about how life can develop on other planets. By examining these windows to Mars, scientists step out of the vicarious and into real features on Earth that function similarly to those on Mars.

We haven't conquered the moon. It's a planet the size of Africa and we've been to six spots the size of a large backyard or farm or ranch. That's not exploring. That's touching.
