NBC announces that it has added a new full-color hour-long science fiction series, Gene Roddenberry’s Star Trek, to its fall 1966 schedule. Unusually, the show has produced two wildly different pilot episodes, with NBC having asked for specific changes to the series format as early as 1965, when it passed on the original pilot, The Cage. One change specifically requested between pilots by NBC, the omission of a “Satanic” alien character named Mr. Spock, doesn’t prevent the network from ordering 16 episodes from Desilu Studios.

The recently-rechristened Environmental Sciences Service Administration (previously the U.S. Weather Bureau) launches, with the help of NASA, weather satellite ESSA-2, intended to be the second in a constellation of spaceborne observers of Earth’s weather. Virtually identical to ESSA-1, ESSA-2 monitors Earth’s cloud cover for over four years; it is decommissioned in 1970, not because it stops working, but because a newer satellite utilizes the same telemetry frequency.
