It's time to open the space frontier to citizen explorers.

I wrote 'Reaching for the Moon' because I wanted to tell kids that all of us have a moon, a dream, that we can strive for. Even if you don't attain it, you can at least reach for it.

This has been far more than three men on a mission to the Moon; more still than the efforts of a government and industry team; more, even, than the efforts of one nation. We feel this stands as a symbol of the insatiable curiosity of all mankind to explore the unknown.

The first human beings to land on Mars should not come back to Earth. They should be the beginning of a build-up of a colony/settlement, I call it a 'permanence'.

For a million dollars, the Russians would take two people, a million apiece, around the moon and back. However, stories, videos that come from the space station, and other people, are a great inspiration to young people for an exciting career field.

Human rights problems will always exist for years to come, but maybe they'll lessen somewhat.

A space program that truly goes somewhere! With his deeds, not only words, President Obama has revitalized our struggling space program.
