Only an artist with a lifelong fixation with space exploration would spend thousands of hours sculpting the forward bulkhead of an Apollo lunar module. That work is part of Tom Sachs’ latest gallery show. 

Sachs took Slate’s Jacob Weisberg on a tour and then sat down for a lengthy discussion about what inspires him and how he and his team create their labor-intensive art.

Here’s the third and final installment from the interview, the latest in our series "Conversations With Slate." 

Also watch Part 1 of the interview, and here’s Part 2. An audio podcast of the entire conversation is coming soon.
