Articles in NASA's weekly published "Space News"  Roundup in the 1960's which was distributed to all employees of the Manned Spacecraft Center (now renamed Johnson Space Center) in Houston, Texas, chronicle the story of how a location for the Apollo lunar landing was determined by the evaluation of possible sites. This was largely accomplished by the unmanned spacecrafts Surveyor and Lunar Orbiter, and by photography taken on Apollo 8. This lesson tracks these articles.
