Before moon landings, scientists thought dust or crust might disrupt touchdown
Moon dust didn’t swallow spacecraft as was suggested in the 1960s. Successful exploration since that has changed our view of the moon.

The moon is about as old as we thought it was
Meteorite heat signatures pinpoint the age of the collision that created the moon — confirming many previous lunar age estimates.
