The photo above of Nafzger holding the memorex spool is a primary source. It is original evidence of the moment pictured. The memorex spool is also a primary source. It held a recording of the Apollo television broadcast. NASA erased the original recordings of the moon landing to reuse them for other projects (Fox, 2009). While this memorex spool is historically significant, it no longer holds the broadcast recording.
