The biggest benefit of Apollo was the inspiration it gave to a growing generation to get into science and aerospace.

I remember it was hard to believe that I was taking a step onto the lunar surface.

There should be an international lunar base. That is certainly doable.

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.

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.

At 10,000 feet, the 3 parachutes would come out, a little lower the pressure of the atmosphere outside was greater than inside, and we could smell the salt air and it was very encouraging to return to earth.

To send humans back to the moon would not be advancing. It would be more than 50 years after the first moon landing when we got there, and we'd probably be welcomed by the Chinese. But we should return to the moon without astronauts and build, with robots, an international lunar base, so that we know how to build a base on Mars robotically.
