This Is Why We Need AstronautsS

When I was at the Kennedy Space Center two weeks ago, I asked one of the Mars Rovers' software engineers if she was sad about the—temporary—end of the US manned space program. Her answer: "Very sad."

But I'm not going to repeat again what Neil Armstrong and 26 other NASA legends already said. And I'm not going to rehash why we need to reach the stars physically, not only virtually. Or describe why Carl Sagan said in The Pale Blue Dot that our destiny is to become wanderers of the cosmos.

I think the image above is a perfect summary of it all. [Original image by Stuart AtkinsonThanks David!]
