Star charts for sea and space look similar, but only this chart includes the planet Earth.
Apollo 11 astronauts used this star chart while training for their 1969 lunar landing mission. It shows the locations, names, and code numbers for a select group of stars. The astronauts would key those numbers into their Apollo Guidance Computer while taking readings with a sextant.
This Star Chart was used to train Apollo astronauts.
