To mark the 40th anniversary of Apollo 11's arrival on the moon, Lo Que Pasa is asking readers to submit memories, stories or snapshots that capture what it felt like on that day.

What were you doing on July 20, 1969? Where did you watch the landing? Who were you with? How did you feel as Neil Armstrong and Buzz Aldrin hopped across the lunar terrain?

Please send your memories and snapshots, along with your name and the unit you work in, to lqp@email.arizona.edu. A selection of the submissions will be featured in the July 15 issue of Lo Que Pasa.
