I think I need to continue to think and plan and marry all of the different things that we could do that make transportation in space from the earth to the space station, from the earth to the moon to space stations around the moon to visiting an asteroid.

Space is not just going up and coming back down again. Space is getting into orbit and being there, living there, establishing a presence, a permanence.

Returning to the Moon with NASA astronauts is not the best usage of our resources. Because OUR resources should be directed to outward, beyond-the-moon, to establishing habitation and laboratories on the surface of Mars that can be built, assembled, from the close-by moons of Mars.

I inherited depression from my mother's side of the family.

Drive over to the nearest airport, and enroll in flight classes. You will experience the joy of freedom in the air above, as you study the mechanics of how this is made possible by understanding the construction, the laws of motion, the air that can provide lift when it is moved by propulsion through the air, and stay above the gravity pulling the airplane back down to earth.

I am excited to think that the development of commercial capabilities to send humans into low Earth orbit will likely result in so many more Earthlings being able to experience the transformative power of space flight.

As someone who flew two space capsules and twice landed in the ocean, I can attest from personal experience how much logistics work is needed to get you home.
