My father's an early aviator, and my first flight was with him at age two. Now, despite the fact that I got sick on the flight, I still enjoyed it, I believe.

Mars has been flown by, orbited, smacked into, radar inspected, and rocketed onto, as well as bounced upon, rolled over, shoveled, drilled into, baked, and even laser blasted.
I'm sure that there are places in the deserts in Australia that could be similar to where we might want to go on Mars.
Mars has a bit of air pressure; maybe we can build up that atmosphere to be a bit more accommodating to humans.
Mars, we know, was once wet and warm. Was it home to life? And what can living and learning to work on its rust-colored surface teach us about the future of our own planet, Earth? Answering those mysteries may hold the key to our future.
One of the major problems with long-term deep space human flight is the requirement for radiation shielding.
What's aero braking? That's a way to use the gravity and upper atmosphere of Earth to sling shot a ship out either deeper into space, or slow it down to be 'captured' by Earth's gravity.
Landing in the ocean and waiting for the Navy to come alongside and haul you out of the drink is what space capsules require. And after the capsule is recovered, it would take weeks for the ship to return to port.
When the time comes to start building deep space transports and refueling rocket tankers, it will be the commercial industry that steps up, not another government-owned, government-managed enterprise.
Save the taxpayer's money by canceling the Ares 1 and V.
