Ready Jet Go! is an animated educational children's television series produced by Wind Dancer Films. The series aired new episodes on PBS Kids from February 15, 2016 to May 6, 2019, although re-runs continue to this day. It was created by animator and Hey Arnold! creator Craig Bartlett,[2] and is produced in cooperation with NASA's Jet Propulsion Laboratory. The show teaches science and astronomy.[3]

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.[4]


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, [5] 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 Propulsion's 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.

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.

Collective name for Earth natives used by the Bortronians.




Space Camp


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."[5] 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.[30] 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.[31] Lenny became Jet and Nate became Sean, while both characters were aged down from 13 to 10.[32] 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 season 2 of the series "hard."[33]

Due to the national success of Ready Jet Go!, the series has been distributed to countries around the world and dubbed into over 20 different languages, enabling it to become internationally successful as well.

In September 2016, the series premiered in Canada on Knowledge Network during the Knowledge Kids block. It also has aired on BBC Kids[42] there. In November of that same year, the series premiered in South Korea on EBS1.[43] The Korean dub of the show was the first foreign-language dub to be produced and aired.

On January 25, 2017, the series premiered in Israel on Educational 23,[44] and later on Kan Educational until November 14, 2020. On February 24 of that same year, the series premiered on Yle TV2 in Finland as part of Pikku Kakkonen, under the title Jetron matkaan.[45] Latin American Spanish and Brazilian Portuguese dubs later premiered on Nat Geo Kids that same year, with the Spanish dub premiering on July 1 and the Portuguese dub on September 20.

In January 2017, the series premiered on LTV1 in Latvia. The show is broadcast in English with one man translating all the characters’ lines to Latvian in the form of a voiceover. On April 13, 2019, the second season premiered.[46]

Beginning February 17, 2021, the series began broadcasting on television in Russia.[47] That same year, the series premiered June 28 on TV Derana in Sri Lanka with a Sinhala dub, and September 27 on Aqlvoy in Uzbekistan under the title Diqqat Jet Olg’a!


Critical reception

Emily Ashby of Common Sense Media rated it a 5/5, saying "Thoroughly engaging and packed with educational content, this exceptional series is a fun way for kids to learn about science and astronomy. Jet's excitement for the human experience is matched only by Sean and Sydney's eagerness to learn all about outer space; put the three of them together, and it's a true celebration of the joy of discovery. Whether it's executing a rescue mission for a Mars rover or combining daily chores with experiments in force, Jet and his friends have a lot to teach kids through their own experiences."[48]

Gina Catanzarite of Parent's Choice said "Although the vocabulary and science explanations may be beyond the scope of the youngest viewers, the premise, characters, interesting art direction and upbeat action should hold their attention. Older kids are more likely to grasp the facts and even if they don't remember them all, Ready Jet Go! will at the very least inspire curiosity, and plenty of questions when they take the time to gaze up at the skies above them."[49]


The series has gained 34.3 million viewers, according to PBS, including 10.2 million on broadcast television. It outperformed channel average by 32% in its first three weeks. The series has also been streamed over 146 million times on the PBS Kids website and app since January 2016.[50]

Awards and nominations


In 2021, two years after the show's final episode aired, Bartlett confirmed that new songs were being recorded for the series.[59] A year later, he confirmed on The Arun Mehta Show podcast that the songs were for an 80-minute Ready Jet Go! movie in production for Universal Pictures. The film was in animation up until October 2022, and entered post-production in spring 2023.[60] The movie, entitled Ready Jet Go!: Space Camp, premiered on July 20, 2023, serving as the series finale.[61]

The plot of the movie revolves around Jet and the rest of Team Propulsion heading to Space Camp. However, Sunspot develops an allergic reaction, prompting the team to go on an intergalactic adventure to find the cure and return to Space Camp before Mitchell finds out.[62][63]
