Someone already rode a bike on the moon?

Somehow, Carson, my nine year old figured this out...
the conversation went something like"...first man on the moon blahblahblah (okay, in my defense, I am brainstorming class ideas and kit projects and layouts for the store) blahblah but I don't think it was Lance Armstrong, it was the other guy, John or Jake or something..."
Neil, maybe?? I said... then googled (love it when I am right)
To which Cars replied, I didn't know someone had been on Juno (apparently, was my husband's naughty answer) and then the golden nugget of discovery...Lance Armstrong rode his bike on the moon.
Who knew?
