Ready Jet Go!

Ready Jet Go! is a CGI animated television series produced by Wind Dancer Films which premiered in the United States as part of the PBS Kids block on February 15, 2016. The series is produced in cooperation with NASA's Jet Propulsion Laboratory. The show is aimed at kids ages 3 to 8. On August 17, 2016, PBS Kids announced that Ready Jet Go! has been renewed for a second season, which premiered on April 2, 2018. The final episode aired on June 17, 2019.

Plot
Ready Jet Go takes viewers on a journey into outer space, building on children’s curiosity about science, technology and astronomy. The series follows two neighborhood kids: Sean, who has an all-consuming drive for science facts, and Sydney, who has a passion for science fiction and imagination. They both befriend the new kid on their street, Jet Propulsion, whose family members happen to be aliens from the planet Bortron 7. Together, they explore the solar system and the effects it has on the science of our planet, while learning about friendship and teamwork along the way.

Why It Rocks

 * 1) It is very educational about science, so much that even adults can learn something new from the show. One adult reviewer from Finland said that this show was the only one which entertained them during Pikku Kakkonen, the block where it aired in the aforementioned country, and it taught them that the sun could hold 1,300,000 Earths and the sun is 109 Earths in diameter.
 * 2) It has beautiful songs composed by Jim Lang, such as You're Never Too Big For a Lullaby, Tiny Blue Dot, and There's No Planet Like My Planet.
 * 3) It has clever comedy and pop culture references, including Cap'n Crunch, Star Trek, The Brady Bunch, Sunset Boulevard, My Fair Lady, From Russia With Love, Led Zeppelin, and more.
 * 4) It breaks stereotypes. It doesn't portray scientists as people who wear lab coats and work in dark rooms, but as regular people in regular offices.
 * 5) The animation improves over the course of the episodes. In fact, some of the new episodes have animations that look like they belong in a Pixar movie.
 * 6) It has important and powerful messages for kids such as "You can't change the past, you can only learn from it", and "Knowing there's a problem should make you want to help solve it".
 * 7) It has some mystery, suspense, and drama in a few episodes, such as the episode My Fair Jet, where Sean almost gets killed. We're not joking. Watch it for yourself!
 * 8) The characters are likable, realistic, and charming, and get development over the episodes.
 * 9) Jet Propulsion is the leader of his group. He never gives up, shows boundless enthusiasm and curiosity when placed into new situations, is very creative and friendly, and displays an optimistic attitude. He's also a goofy kid who likes to burst into song and often has wacky ideas, bringing humor into situations.
 * 10) Sean Rafferty is a neurotic science nerd who likes to be scientific. He was originally a huge coward about going to outer space, but as the episodes go on, he gets over it. In fact, he even starts to like it.
 * 11) Sydney Skelley is a smart, imaginative girl with big dreams, and an ambitious go-getter with admirable qualities.
 * 12) Mindy Melendez is a little girl who likes to ask big questions. She can't go to outer space with the big kids until her fifth birthday in season 2 though, but she's mostly fine with that. Younger viewers can find Mindy rather relatable.
 * 13) Jet's pet, Sunspot, is the energetic, playful Bortronian bunny-like animal who likes to entertain the kids. He is cute, fun to watch, and is funny at times.
 * 14) The recurring characters, including Mitchell Peterson (a loner detective that acts like a jerk to hide it), Lillian (a ditzy but sweet girl) and Dr. Bergs (a coffee-loving scientist) are all excellent as well.
 * 15) It has incredibly hammy and over the top voice acting, executed in a humorous and entertaining way, with Canadian voice talents such as Ashleigh Ball, Brian Drummond, and Ian James Corlett.
 * 16) Many of the children are voiced by actual children.
 * 17) The Amy Mainzer live-action segments in the show are as educational as the series itself: they are understandable; have excellent, detailed explanations, and you always learn something new.
 * 18) The show got two movies with plots that balance humor, education and drama: Back to Bortron 7 and One Small Step.
 * 19) The plots are simple, but are executed greatly.
 * 20) The show is like Alf, Invader Zim, Marvin Marvin, and Mork & Mindy in that there is an alien living on Earth, but the show does its own unique take on the trope.

Bad Qualities

 * 1) The voice acting was grating in the first few episodes. This could be attributed to the the child voice actors not being used to their roles.
 * 2) In the earlier episodes, the animation was somewhat stiff and poor.

Trivia

 * Craig Bartlett also created the shows Hey Arnold! and Dinosaur Train.
 * On that note, several people who work on this show (e.g. Joe Purdy and Jim Lang) have also worked on those two shows as well.
 * Jet's voice actress, Ashleigh Ball, also voiced Rainbow Dash and Applejack from My Little Pony: Friendship is Magic, Blythe Baxter from Littlest Pet Shop, Gilbert Troodon from Dinosaur Train, and Mary Test in Seasons 2-4, and 6 in Johnny Test.
