NASADA

The NASADA is a space program headed by General Norquist. The space program apparently knows about the existance of extra-terrestrial inhabited planets because when Justin mentioned that the Power Rangers needed to get to Eltar in "Chase into Space", General Norquist, immediately knew there was danger. A Space Shuttle designed by NASADA, which the program allowed the Turbo Rangers to blast off into space with, when activated by a Power Decoder, Alpha 6 brought from the destroyed Power Chamber, combines with the Astro Megaship to form the Astro Megazord. Thus, the Space Shuttle must have been built by NASADA for this purpose on the request of Zordon.

Years later, NASADA is still an ally of the Power Rangers, as they allowed 10 Red Rangers in Forever Red to meet up there in order to dock on the Astro Megaship Mark 2 to fly to the moon.
