NASADA is a space program headed by General Norquist.
History[]
The space program apparently knows about the existence of extra-terrestrial inhabited planets because when Justin Stewart mentioned that the Power Rangers needed to get to Eltar, 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 that 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.
Occasionally, NASADA has requested the help of the Rangers, such as when a satellite containing discs with important information was brought down, or when NASADA astronauts had crashed on a desert world (though that turned out to be a ruse by Darkonda.)
Couple years later, NASADA is still an ally of the Power Rangers, as they allowed 8 Red Rangers in "Forever Red" to meet up there in order to dock on the Astro Megaship Mark II to fly to the moon.
Later still, the organization is mentioned by Ravi Shaw, indicating that it is still active.
During Halloween, Ollie Akana is wearing a space man costume that has the NASADA symbol.
