Ready Jet Go! is an American animated educational children's television series created by Craig Bartlett and produced by Wind Dancer Films that aired on PBS Kids from February 15, 2016, to May 6, 2019. Produced in cooperation with NASA's Jet Propulsion Laboratory, the show teaches science and astronomy.

The show is aimed at children 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.

Plot Jet Propulsion and his family are aliens from the planet Bortron 7, which orbits around a red dwarf called Bortron. The Bortronians largely resemble humans, but have elastic bodies. The Propulsion family lives at Boxwood Terrace in Washington state, where they study human customs and Earth environments for a travel guide. Jet has made friends with neighborhood children, 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 children into space. Their alien identities are known to Sean, Mindy and Sydney, but they otherwise make some effort to conceal their origin. However, a boy named Mitchell Peterson who lives next door is in on Jet's alien behavior and wants to expose his identity.

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.

Episodes

Characters

Main Bortronians Jet Propulsion (voiced by Ashleigh Ball) is the title character of the series. 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. Sunspot Propulsion is the Propulsion family's pet. He has a kangaroo-like body, rabbit-like ears, and a raccoon-like tail. Sunspot knows how to read, can talk and sing, and can follow conversations, but often seems confused about what behaviors are expected from a pet. Carrot Propulsion (voiced by Kyle Rideout) is Celery's husband and Jet's father. He often stays home while Celery takes the kids on adventures into outer space, as he does not like traveling in the flying saucer. Carrot often cooks wacky dishes such as deep-fried lollipops. Celery Propulsion (voiced by Meg Roe) is Carrot's wife and Jet's mother. Celery is smart and often takes the kids to space. She normally drives the family vehicle, as Carrot's driving makes her nervous. Face 9000 (voiced by Brian Drummond) is a computer who helps answer the kids' science questions. In "Face on the Fritz", he gets an upgrade. He has a tendency to get jealous easily.

Earthies Collective name for Earth natives used by the Bortronians. Sydney Skelley (voiced by Dalila Bela in season 1, Vienna Leacock in Back to Bortron 7-season 2) is a girl with black hair and green eyes. She idolizes a character named Commander Cressida, named after the moon of Uranus, who has a dog named Sirius, named after the brightest star in Earth's night sky. Sydney is imaginative and very friendly, often acting as the voice of reason for the kids. Sean Rafferty (voiced by William Ainscough (seasons 1-Our Sun is a Star!), Grady Ainscough (in You Can Call Me Albedo-Moon Face), Glen Gordon (in Lone Star 2 - Rocket Kids!-One Small Step), Anthony Bolognese (Space Camp) is a boy who is smart and wants to be an astronaut when he grows up, but he has slight claustrophobia. Sean idolizes Neil Armstrong and has an action figure of Armstrong, which he takes along on space trips. Mindy Melendez (voiced by Jaeda Lily Miller) is a girl who is friends with the Propulsion family, but was initially not allowed to travel to space with them. In the second season, Mindy turns five years old and is allowed to travel into space.

Supporting Bortronians Zucchini (voiced by Ian James Corlett) is Jet's maternal uncle, Zerk's father, Eggplant's husband and Celery's brother. He is a garbage collector on Bortron and works for the East Galaxy Garbage Company, Bortron 7 Division, using the Big Bortronian Junk Sucker (BBJS). Moonbeam is Zucchini's pet. She looks similar to Sunspot, but Moonbeam is blue and plays electric guitar (left-handed). Eggplant (voiced by Tabitha St. Germain) is Jet's aunt, Zucchini's wife and Zerk's mother. She is an intergalactic travel writer just like Carrot and Celery. Zerk (voiced by Meg Roe) is Zucchini and Eggplant's son and Jet's cousin. Spinach is Celery's cousin. Celery calls him when the van/flying saucer is not working and she needs advice.

Earthies Mitchell Peterson (voiced by Spencer Drever in season 1, David Raynolds in season 2, Dylan Schombing in One Small Step, Gordon Cormier in Space Camp) is suspicious of the Propulsions' behavior and always wants to expose Jet's alien identity, but inevitably fails. In "Holidays in Boxwood Terrace", it is revealed that he only pretends to be mean, is really shy and wants to be friends with Jet, Sean, Sydney, and Mindy, but did not know how to go about doing so. In the end, the kids welcome him into their group. Mr. Peterson (voiced by Ian James Corlett) is Mitchell's father and the self-appointed safety officer for the neighborhood. He, like his son, can be a bit full of himself. He is an expert at playing mini-golf. Dr. Rafferty (voiced by Keegan Connor Tracy) is a scientist and Sean's mother. Dr. Bergs (voiced by Brian Drummond) is Dr. Rafferty's coworker. Dr. Melendez (voiced by Meg Roe) is Mindy's mother. Lillian (voiced by Amelia Shoichet Stoll) is a friend of Mindy's. The two girls dig a small "Grand Canyon" in a sandbox while the Propulsions and the other children visit Valles Marineris on Mars. Beep is a robot who lives at the Deep Space Array (DSA). She has a twin sister, Boop, who is a Rover on Mars. Dr. Skelley (voiced by Brenda Crichlow) is Sydney's mom, who also works at the DSA. Like her daughter, she is also a fan of Commander Cressida. She is a robotics engineer.

Space Camp The Great Galacto (voiced by Mark Oliver) is Jet's idol. He's a TV and web personality who goes on daring space adventures. Like Sunspot, he is allergic to comet dust, which causes him to shrink. Stella Singularity (voiced by Viva Lee) was the Great Galacto's number-one fan until Jet took her place. Stella got jealous, and went to planet Earth to confront Jet, but winded up going to space camp, and was placed on Mitchell's team. Stella is sarcastic and narcissistic; she always wants to be the best at everything, does not understand teamwork, and is frequently seen primping herself. When she got stuck in a web in the caverns of Mascarpone, she realized the value of teamwork. From that point on, she apologizes to Jet for how she acted and is nicer to him and the others from that point on. Dr. Chandra (voiced by Ana Sani) is an astronomer and "expert on alien life", who visited Boxwood Terrace to judge the spaceship design contest at space camp. Mitchell tried to tell her that Jet is an alien, but to no avail. Aurora (voiced by Diana Tsoy) and Houston (voiced by Gabriel Jacob-Cross) are two kids who invite Mitchell and Stella to join their team. They love space, and emphasize the importance of teamwork.

Development The idea for the show dates back to the late 1990s when Linda Simensky complained to Bartlett about how "nobody makes shows about two friends anymore". From that idea, Bartlett came up with Lenny and Nate, a buddy comedy starring two eighth-graders, one of whom believes he is an alien. It was pitched to Cartoon Network. Years later, while working on Dinosaur Train, Bartlett revamped the idea to be educationally appropriate for PBS, with a specific focus on space and earth science, after he worked on a project for NASA called the Shuttle Launch Experience. Lenny became Jet and Nate became Sean, while both characters were aged down from 13 to 10. The character of Sydney was added, and after testing the initial pilot of children, Mindy was added to appeal to a younger audience. The pilot was titled Jet Propulsion.

During production of the first season, PBS approved of everything that Bartlett and his team came up with, leaving no notes. However, during the second season, the team was approached by the Ready-to-Learn Act, thus bringing a new layer of oversight and executive meddling that made the second season "hard".
