CSF and its members believe strongly in the exploration of space of all kinds, including commercial purposes.

I'm hopeful that commercial space exploration will takeoff. To really fuel the spaceflight revolution will require an investment of hundreds of billions of dollars a year, and I think that's only going to happen in the commercial sector - if there are large profits to be made.

We made more than just scientific discoveries... we rediscovered how much people love exploration.

New Horizons isn't just visiting Pluto; it's visiting this entire region. Whatever it finds, this will be a signal moment for planetary exploration - the capstone to our first reconnaissance of the planets of our solar system.

Luckily for writers - and unluckily for history - every scientific idea creates human conflict.

My only wish would be to have 10 more lives to live on this planet. If that were possible, I'd spend one lifetime each in embryology, genetics, physics, astronomy and geology. The other lifetimes would be as a pianist, backwoodsman, tennis player, or writer for the 'National Geographic.'

The process of science is difficult and challenging. It involves always being aware that your ideas might be right or they might be wrong. I think it's that kind of balance that makes science so interesting.

My scientific studies have afforded me great gratification; and I am convinced that it will not be long before the whole world acknowledges the results of my work.
