Ready Jet Go!

Mindy has finally turned five and is super excited that she is now old enough to go to space. But she's planned a tea party in the backyard. The kids convince Mindy to move her tea party to the Moon! In her first trip to space ever, Mindy gets to board the Propulsion family saucer and experience space travel, rounding out their Moon tea party with a quick trip out to Pluto and back.

Jet is amazed to find out that the entire Earth doesn't have the same season at the same time. So he flies with Sydney and Sean from the northern hemisphere to the southern hemisphere to compare and experience holidays in winter and summer...all in one day!

Mindy feels bad that she's the smallest kid in the group, so sympathetic Jet and friends use a shrink-ray and become her size. The plan goes awry, and Jet, Sean, Sydney, and Sunspot become the size of mice. Mindy has to follow intricate diagrams to reverse the shrink-ray!

Mindy is impatient for winter, because she wants to ice skate. So Jet, Sean, Sydney, and Celery fly to Saturn's icy rings to gather ice from them and return to build a Saturn-ringed skating rink around Jet's house.

Jet, Sydney, Sean, Mindy, and Sunspot decide to make a scaled replica of the solar system using found items in their own neighborhood and in doing so learn that an Astronomical Unit is the distance from the Earth to the Sun.

Celery takes the kids on a saucer tour all around the Earth to discover all the ways that water can be found. They visit Antarctica to look at the ice, and then compare that extreme to the icy surface of Jupiter's moon Europa.

While making a cake, Carrot and Mindy find they are one are short one ingredient, so they head to the store. But Carrot accidentally pushes a wrong button on the wagon's newly-updated control panel, and they take off into outer space! Using a diagram, methodical experimentation, and record keeping, Mindy and Carrot figure out how to properly fly the saucer back home, where they finally finish the cake.

Mindy has a problem: now that she's been to space with the bigger kids, she realizes how much there is out there to see! How can she decide where to explore next? Sydney asks her mom, Dr. Skelley, who presents them with the very first edition of Commander Cressida comics! In reading the comic book, Mindy comes to appreciate that she, like Commander Cressida, can explore space "one adventure at a time."

Mindy has to go to bed when the Sun goes down, but she's having such a fun day with her friends. She asks Jet and the others to help her keep the Sun from going down. The older kids humor Mindy and try to help "slow down the Sun." All their efforts make Mindy so sleepy that she decides to go home and sleep.

Sydney and Jet are having a hard time explaining to Mindy that the Sun doesn't move - the Earth is moving around the Sun, so the Sun seems to move. Then Sean comes over dressed as his science hero Galileo, getting ready to do a school report. Mindy asks "Galileo" to explain why the Sun seems to move, and Sean practices for his report by explaining how the planets move, in character as Galileo!

Sean is planning his first sleepout under the stars with his Space Scouts troop, but the weather is threatening and it looks like his sleepout will be rained out. The kids get help from Mitchell, building a weather observation station to make a weather prediction, and visit the DSA for further help by tracking the weather with satellites.

A total eclipse of the Sun is coming to Boxwood Terrace! The kids prepare a Total Eclipse song and dance to perform at the DSA, where the whole town is gathered for the event. Meanwhile, Sunspot attempts to explain the eclipse to all the local animals so they won't think it's night and sleep through it.

Celery has souped-up the family saucer, adding new features for the kids to use, including a robot arm. They test drive it with a trip to the Moon.

Jet takes care of Mitchell's dog Cody for the weekend, and attempts to teach him some new tricks.

When the kids experience an earthquake in Boxwood Terrace, Celery takes them up into space to study the Earth's plates and fault lines from above.

Jet's overactive cousin Zerk comes to Earth for a visit, and the kids show him around the neighborhood.

The kids join Celery in a space race with Uncle Zucchini, Auntie Eggplant and Zerk.

Sydney designs and builds a robot companion for Jet 2.

Sydney wants to enter a Commander Cressida story contest, but can't think up a good enough story. The other kids help, and they come up with a story about lassoing a comet to bring water to Venus, and then Mars.

Jet is fascinated by the effects of wind on his saucer. He and the kids study how wind works, ending with Sean going on a wild saucer ride.

Jet is fascinated by Earthie golf, and Sean and Sydney try to teach him the rules. When the DSA builds a new mini-golf course, the kids team up against the grownups, and Jet gets to apply his new knowledge of force.

Jet's robot Jet 2 needs new wheels if he's going to be able to rove over the surface of Mars. Jet and the kids try a bunch of different wheels, without success. In the end, they borrow the wheels from Mitchell's scooter, so Jet 2 can successfully navigate on Mars.

The kids enter their karts in the big kid-kart derby, but this year they all have to design solar powered karts. Jet learns how solar panels work, and how batteries save up the energy so you can race even when clouds cover the Sun.

It's evening at the cul-de-sac, and the kids are looking at two asteroids through Sean's telescope - one is light-colored and one is dark. Meanwhile, Mitchell's dog Cody seems to have run away because he doesn't like the black sweater Mitchell put on him. The kids learn about how, just like asteroids, some things are easier to see in the dark than others, like a white card is easier to see than Cody's black sweater. This amount of brightness is called 'albedo'.

The kids go to their local beach to surf, but notice that the beach looks completely different from the last time they stood there. There's way more sand, and the ocean is far away! They decide to be detectives and study what has happened, and learn that the larger and smaller beach is caused by the tides - the rising and falling of the ocean.

The kids are attempting to grow prize-winning pumpkins in the back yard. Jet gets carried away and uses his Bortronian Grow-Lamp to grow a huge pumpkin. Now they just have to get his enormous pumpkin downtown to win the contest!

Sydney tells the class the story of the first astronaut, Lone Star.

The kids start a hands-and-eyes investigation when a large, unusual bird shows up in Jet's back yard.

Sean accidentally drops his beloved Neil Armstrong action figure into a large crack in the ground, so the kids all work together to engineer a robotic arm to reach down into the crack and rescue Neil!

When Astronaut Ellen Ochoa comes to visit the DSA and review an engineering project, she runs into the kids, who are running Sean's lemonade stand to raise money for a rocket to Mars. They end up hanging out with her before her DSA meeting.

Astronaut Ellen Ochoa and the kids solve an engineering problem together, which inspires Ellen to use the same solution with the engineering project at the DSA.

Jet is fascinated by the Earthie potatoes that the kids have grown in the backyard garden. Now he wants to try to grow potatoes on Mars! They take several plants to Mars and try, but learn that potatoes need the right air, temperature, water, and even the right soil.

Jet is fascinated by his first Earthie rainbow. He wants to know all about them! Sydney tells Jet about the mythical Leprechauns that keep a pot of gold at the end of the rainbow, and even though they explain that it's only a story, Jet insists on following the rainbow to its end and meeting a magical leprechaun.

The kids do a bunch of projects in the treehouse, but they leave a lot of trash and no one wants to take responsibility for it. They learn to share the responsibility for keeping the treehouse clean.

Mindy tells Jet that clouds are made out of cotton balls. Jet, of course, believes this, but Sean and Sydney don't. Mindy says she learned this from Lillian. The kids go to Dr. Rafferty and Dr. Skelley, who teach them what clouds are really made of and how to find correct information.

It is Carrot's 250th birthday, so the kids make a circus to celebrate. The kids can't do their stunts on Earth because of the high gravity so they move the circus to the moon, where everyone can do their circus tricks due to the low gravity.

On Earth Day, the kids decide to make posters to celebrate. The kids travel around the Earth to find out what makes Earth so special.

The kids play shadow tag but clouds cover the sun, ending their game. The kids learn about a planet with three suns, Proxima B, and travel there see how having three suns affects their shadows.

Sean presents a magic show for the kids (and Carrot). After impressing them with a string of paperclips seemingly held end-to-end by an unseen force, he explains that the trick was done with a magnet he held in his hand. The kids decide to investigate how and when magnets work, and then use their knowledge to put on another magic show for Carrot.

Sunspot is sick and acts weird. This is because of a big Sunspot on the sun. He gets cured when he gets closer to the Sunspot.

Lillian has a sleepover with Mindy planned, but it's too cold to have a sleepover outside.
