Today's 40th anniversary of the lift-off of Apollo 11 on its voyage officially kicks off what are surely going to be many days of memories and reports about the first time men stepped on the moon (that anniversary comes Monday).

If you were around in 1969, were you watching and what do you remember most about the mission to the moon? Add your thoughts in the comments thread or over at Twitter (tag it Apollo11memories; we'll spotlight some of the best).

My memory is probably like many others': Being glued to our black-and-white TV -- Walter Cronkite on CBS -- throughout the mission. And thinking that it wouldn't be much longer before astronauts went beyond the moon. Oh, the optimism of youth.

Today on Morning Edition, by the way, NPR's Nell Greenfieldboyce reported that "an exhaustive, three-year search for some tapes that contained the original footage of the Apollo 11 moonwalk has concluded that they were probably destroyed during a period when NASA was erasing old magnetic tapes and reusing them to record satellite data."

Here's her report:

There's video of Neil Armstrong stepping on to the lunar surface here.

Update at 9:10 a.m. ET: For a very interactive way of seeing how the Apollo 11 mission unfolded, go to We Choose the Moon, a website from the John F. Kennedy Presidential Library & Museum. It's counting down to "the launch" right now.

It's also tweeting the mission, as if it were happening today.
