I was wondering how long did The Jetsons air in the 1980's

Forty new episodes were syndicated during the 1984-1985 season. Surprisingly, all the original actors (George O'Hanlon as George, Penny Singleton as Jane, Janet Waldo as Judy, Daws Butler as Elroy, Don Messick
as Astro, and Jean Vander Pyl as Rosie) were reunited to record the voices
of the characters from the 1962-'63 ABC prime-time series. In addition, Don
Messick was the voice of the new character, Orbitty. Ten more new episodes
were syndicated duiring the 1987-1988 season. So, altogether, there were 50 episodes made in the 1980s. (Only 24 episodes were made for the show's
original run in the 1960s.)

I wish I could remember the 1980's edition of The Jetsons

Forty new episodes were syndicated during the 1984-1985 season.
The 1980s show first appeared on September 17, 1985 and two years later, 1987 a third series was involved.

Frank Welker was the voice, not Messick.

The 80's Jetsons had a new character...Orbity who was an Alien....
