Orbiting observatories


The Orbiting Geophysical Observatory, or OGO, was a 20th century series of artificial satellites used by NASA for studying the Earth's magnetosphere.

A black-and-white drawing of the satellite was stored in the USS Enterprise library computer. This drawing was retrieved by the Talosians when they accessed the starship's computers in 2254. (TOS: "The Cage")
