Here is another question a little less technical.

When Charlie Duke left to go to the Moon on Appollo 16, he took with
him a family picture and took a shot of it on the Descartes hills:

I found out about it when I bought the book of Michael Light's "full
moon".

The story does not say if that photo was taken back or if it was left
on the moon ?
How do I figure that out besides talking to Charlie ?

Thanks in advance for any insight.
