It's funny to hear all the youngsters (my assumption) whining about leaving the cameras on the moon. Every aspect down to the last ounce was calculated. A the lunar Hasselblads had a mass of about 2 pounds.. that is a lot of rock samples.
THe cameras that were in the command module made it home, what an impressive accomplishment. Every time I see Mr (Comander) Amrstron (and Cernan) I am in awe that they got on top of that rocket and figured just a 40% chance of making it back home (Armstrong at least, Cernan had confidence as it had been done.) PS Cernan piloted the lunar lander TWICE two different trips to the moon. He joked that he would have landed it on Apollo 10 (lunar decent test mission) if he had enough fuel to get back.
