  • show Description
  • Three young humans were taken from Earth thousands of years ago. On an advanced alien planet, they were imbued with special powers and trained to defend and protect the Earth and its surrounding space. Returned to Earth in modern times, they act as superheroes, based in a spacecraft which is normally hidden inside the caldera of a dormant volcano. The trio includes Astraea, an African woman who has the power to assume the form of any animal. Hercules is a cave man (originally barechested in a loin cloth) who has super-strength. Mercury is a Chinese man given super-speed. All three were given rocket belts for flight and they're supervised, advised and dispatched by a sentient supercomputer on their ship, Sentinel One, who appears in the form of a floating disembodied head (similar to but pre-dating the Mighty Morphin' Power Rangers). Completing the list of characters was a small robot, Maintenance Operator, usually called "MO" (pronounced Moe). Able to hover and fly and equipped with four arms and two legs, MO was responsible for the repair and maintenance of the ship and is infatuated with Astraea. The show's producers say his resemblance to the robots in the movie Silent Running was intentional. The show's main cast reflected the various races of the main characters. African-American Dee Timberlake and Korean-American Evan Kim joined George DiCenzo as the voices behind the cels. The show concept has been compared to the Green Lantern Corps from the Green Lantern comic books published by DC comics. The show was originally called The Young Sentinels, but NBC thought the name was too generic, leading to a title change late in the season that emphasized their space background. However, because all episodes had already been produced, dialog throughout the series refers to them as Young Sentinels. For the 2006 DVD release, all of the episodes were given the revised Space Sentinels opening title sequence rather than the original that the earlier episodes had.moreless

    • MO: I don't like this at all. Earthquakes give me the shakes.

    • MO: Think, S-1! Use that big, wall-to-wall brain of yours!

    • Mercury: Now I know why they call camels the "ships of the desert." I'm getting seasick.

    • MO: Gee, thanks, S-1! You're all heart. Sentinel One: Negative, Maintenance Operator. I am all ... head.

    Notes (6)

    • This episode displays yet more similarities to DC Comics' Green Lantern comics. Morpheus is equivalent to the comic series' Sinestro character. Both characters were recruited for the Corps and given powers equal to the heroes but later turned evil.

    • When discussing the robots' footprints, the Sentinels use meters as a unit. In the 1970s, the United States was widely expected to convert to the metric system. Congress passed the Metric Conversion Act of 1975 toward that end, but public resistance was too strong. The act was rescinded six years later and the US remains the sole industrial nation holding out against metrification.

    • This story is similar to the Star Trek: The Animated Series episode "One of Our Planets is Missing," aired three years previous and also produced by Filmation. In both episodes, an unbeatable foe is eventually contacted telepathically, is told that it is consuming intelligent life and is convinced to stop feeding.

    • First episode to be broadcast with the revised series name The Space Sentinels instead of the original title, The Young Sentinels.

    • Plot bears a striking resemblance to The Andromeda Strain (1971), about an Earth probe returning with an alien virus.

    • Resembles the Star Trek episodes "For The World Is Hollow And I Have Touched The Sky" and "The Paradise Syndrome", with it's themes of a civilization on a doomed planet about to collide with another.

    Trivia (4)

    • Goof: When the Sentinels complete their mission, Astrea reassures MO that they're back, but MO's eyes are flashing during those words as if he was speaking them.

    • Goof: Inside the mountain base, there are four robots operating, while only three took part in the heist and later exit the base.

    • This is the first episode to mention that the Sentinels have rocket belts rather than the power of flight. This bears a strong resemblance to DC Comics' Legion Of Superheroes series at that time in which all non-flying members were issued a ring worn on finger that gave them power of flight.

    • Goof: In the first scene inside the Sentinels' ship after Astraea is abducted, Sentinel One is seen mouthing the words while Hercules' voice says "Then it was magnetic energy that pulled Astraea into that ship."
