Wow. Really amazing when I stop to take it in: NASA got people to the moon and back, not once but several times. And that was way back then. Forty years ago to be exact. Recent photos show shadows of the lunar landers that were left on the moon. More information on NASA's celebration of the 40th anniversary are found on their website. Somewhere there was a list of fun facts but I can't find it now. One of the facts was that the moon was so hard that they were barely able to get flag but a few inches into the surface and then had to be careful not to knock it over. Also the lander legs didn't compress as much as it should and Neil had to take a jump to get onto the moon surface. It's pretty amazing that they were able to get live video from the spacecraft and from the moon back to earth. And all those buttons and switches! In any case the complexities of the whole affair is mind-boggling.
