Ready Jet Go! is an American-Canadian CGI animated television series produced by Wind Dancer Films. The series aired on PBS Kids from February 15, 2016 to May 6, 2019. It was created by animator and Hey Arnold! creator Craig Bartlett, and is produced in cooperation with NASA's Jet Propulsion Laboratory. The show teaches science and astronomy.

The show is aimed at kids ages 3 to 8. On August 17, 2016, PBS Kids announced the renewal of the series for a second season, which premiered on April 2, 2018.


Jet Propulsion and his family are from the fictional planet Bortron 7 which orbits around a red dwarf called Bortron. They live at Boxwood Terrace in Washington,

where they study human customs and Earth environments for a travel guide. Jet has made friends with neighborhood kids, including Sydney, Mindy, and Sean, whose parents work at the nearby Deep Space Array. The Propulsions' car turns into a flying saucer, which they frequently use to take the older kids into space. Their alien identities are known to Sean, Mindy, and Sydney, but they otherwise make some effort to conceal their origin. As of early June 2016, it's unclear whether anyone else knows who they really are.

At the end of each episode, scientist Amy Mainzer (also called Astronomer Amy) hosts educational interstitial segments: the segments are not included in the export version.


List of Ready Jet Go! episodes


  • Jet Propulsion (voiced by Ashleigh Ball) is the title character of the show and is a humanoid alien. He has red hair and can stretch his body, as his parents can. He is excitable, energetic, and goofy. He is tall for his age. Jet is 63 years old in Bortronian years, as revealed in "Earthday Birthday". He was instantly popular with the other children the moment he arrived on Earth. He sees the mundane world as a vast and exciting place, and even thinks that words are exciting, such as "surprise", claiming it to be a funny Earth word. He is named after the Jet Propulsion Laboratory. He is shown to be extremely kind, even to people who are mean to him, such as Mitchell. He possibly likes Sydney, because he danced with her in "How Come the Moon Changes Shape?", and is shown to possibly like Sean in "Back to Bortron 7".
  • Sunspot Propulsion is the Propulsion family pet. He is described as a dog or cat to "Earthies" not in the know. Sunspot has the ears of a rabbit, the body of a kangaroo, and the tail of a raccoon or a fox. He plays concertina, electric guitar, bugle, pan pipes, and drums. Sunspot is silly and likes to play. His status as a mere "pet" may be somewhat of a put-on: He knows how to read, can talk and sing, and can follow conversations, but often seems confused about what behaviors are expected from a pet. He often functions as a deus ex machina, figuring out what is going on and what needs to be done and then conveying that information to one or more of the children. Carrot and Jet both realize there's more to Sunspot than the obvious, as evidenced by a conversation in "The Greatest Canyon": Carrot: "You ever get the idea there's something he's not telling us?" Jet: "All the time, Dad. All the time."
  • Carrot Propulsion (voiced by Kyle Rideout) is Jet's father. His name from his home planet includes the sound of an elephant trumpeting and a parrot squawking. He tends to be goofy, like Jet. He often stays home while Celery takes the kids on adventures into outer space, as he doesn't really like going in the flying saucer. Carrot often cooks wacky dishes such as deep-fried lollipops.
  • Celery Propulsion (voiced by Meg Roe) is Jet's mother. Celery is smart and often takes the kids to space. Her name from her home planet includes the sounds of banging, buzzing, and clanging. She normally drives the family vehicle, as Carrot's driving makes her nervous. She likes racing against her brother, Zucchini.
  • Face 9000 (voiced by Brian Drummond) is a computer. He is a cyan face with blue facial features projected from a small, round ball. He has a younger brother, Face 9001. Face 9000 knows everything about science, and often pops up to answer the kids' science questions. In "Face on the Fritz", he gets an upgrade. He has a tendency to get jealous easily.
