I am, and ever will be, a white-socks, pocket-protector, nerdy engineer.

History will remember the twentieth century for two technological developments: atomic energy and space flight.

Ever since I was a little boy, I dreamed I would do something important in aviation.

I am, and ever will be, a white-socks, pocket-protector, nerdy engineer - born under the second law of thermodynamics, steeped in steam tables, in love with free-body diagrams, transformed by Laplace, and propelled by compressible flow.

Hey, we missed the whole thing.

The [Moon] surface is fine and powdery. I can kick it up loosely with my toe. It does adhere in fine layers like powdered charcoal to the sole and sides of my boots. I only go in a small fraction of an inch, maybe an eighth of an inch, but I can see the footprints of my boots and the treads in the fine sandy particles.

The view of the moon that we've been having recently is really spectacular. It fills about three-quarters of the hatch window, and of course we can see the entire circumference even though part of it is in complete shadow and part of it is in earthshine. It's a view worth the price of the trip.
