This weekend marks the 50th anniversary of the Apollo 11 landing, the first time humankind stepped foot on the moon.

Even 50 years later the historic feat stands as a monument to American perseverance and technological ingenuity, but while those brave astronauts were up there, they were doing more than just planting flags: they were also getting some important science done as well.

On this edition of KCBS In Depth, we mark the moon landing anniversary by holding a conversation on lunar science to find out what we've learned so far and what future missions to the moons still could teach us. 

Host: KCBS Radio Reporter Keith Menconi 

Guest: Andrew Fraknoi, emeritus chair of Foothill College’s Astronomy Department, who currently teaches at the Fromm Institute at the University of San Francisco
