Winter had glowing words for Hubbard when he wrote, "Ron's technical insight of the recording process was outstanding."

Winter also described Hubbard's delineation of counter-rhythm in rock as something "which was nothing short of phenomenal, particularly inasmuch as it had then been entirely unexplored and only later heard in the African-based rhythms of Paul Simon's work, some five years after Ron’s analysis.

"[3] The science fiction cover artwork for the album and cassette tape feature a blond man, resembling Winter, floating in the clouds behind an iron fist that appears to be holding a representation of the Earth.

Some versions of the album were sold with a gold foil sticker that said, "Words and Music by L. Ron Hubbard".

The album was predicted to sell 800,000 copies by Rhino Entertainment[citation needed]; however, it probably sold poorly due to the lack of any public interest in Mission Earth as well as Hubbard's infamous status likely swaying away anyone who wanted to buy the album.
