Slice of History: Ranger 7 Spacecraft Model
Each month in “Slice of History” we feature a historical photo from the JPL Archives. See more historical photos and explore the JPL Archives at https://beacon.jpl.nasa.gov/.
Several different full-size and scale models were made of the Ranger spacecraft (Block I, II, and III configurations). Scale models were used by the projects at NASA’s Jet Propulsion Laboratory at a time when there was no computer animation. Engineers and scientists used them to visualize the spacecraft and its orientation as it reached the moon or a planet.

Kuiper was the director of the Lunar and Planetary Laboratory (LPL) at the University of Arizona. Whitaker was a research associate at LPL. Heacock was the Lunar and Planetary Instruments section chief at JPL.
