The Armstrong Center was a settlement on Earth's moon of Luna and was built on reference stardate -1/9904 during a period when more lunar stations were opened by various nations as well as several private corporations. This center was the largest of the new colonies and became a small city populated by scientists, technicians and support personnel.
