Jet attempts to play the "Solar System" game with Sean, Sydney, and Mindy, but the kids don't quite understand which planets go where. Celery, Jet's mom, takes them on a tour of the solar system and introduces each of the eight planets.

Sydney, Mindy, Sunspot, and Sean help Jet cook a classic meal from Bortron 7 for his parents, Celery and Carrot. After some funny attempts, the kids find that using the Scientific Method works best to get the meal done in time.

Sean explains to the others that Earth is a "Goldilocks" planet because it's not too hot and not too cold. When Celery takes the kids to space, they observe how the other planets don't have the right attributes to support life, but Earth is "just right!"

Jet, Sean, and Sydney visit their Mars Robot Rover friend at the DSA, and discover that the rover seems tired. Through helping the solar powered robot regain its energy, they learn how energy can be captured, used from the Sun, and used anywhere - even on Mars.

Sydney, Jet, Sunspot, and Sean fix up a treehouse and make it into their own clubhouse/observatory. The kids even build their own telescope so they can all observe the awesome nighttime sky!

Mindy is shocked to learn that there is more than one moon in the solar system. Celery flies the kids out to Mars so they can see what its two moons look like compared to ours.

Sean and Sydney take Jet to meet Sean's mom, a scientist, at the Deep Space Array. She explains that they're looking for stars with their own systems of exoplanets to detect if there might be any that contain life. But will taking Jet out in public expose his secret identity?

When Jet and Sydney interrupt Sean doing some training in his backyard, it leads to a pretend mission to Mars.

Sean and Sydney take Jet to see a show at a planetarium.

Sean sets up a sno-cone stand to help raise money to send a spaceship to Mars. But it's the hottest day of the year and he quickly runs out of ice, and he can't find any nearby. Then Jet has an idea where they can go to get some ice-Saturn's ice moon, Enceladus!

Jet builds a mini-flying saucer in his garage and wants to test it, but to succeed, he has to learn what gravity is and how it works.

A major storm on Saturn is mistaken for a storm on Earth.

Mindy and Carrot want to make desserts that represent the different planets of the solar system for a cooking competition, but can't remember whether Saturn is hot or cold.

Jet builds an electric engine from scratch for the annual soapbox derby competition, but Mitchell, determined to win the derby, is suspicious that Jet is using some alien technology.

Sean's determined to beat his mystery competitor at a video game of "Astro-Tracker." He realizes that the best way to learn about asteroids is to see them for himself.

When Mindy and Sunspot are digging in the yard, they discover a unique rock that Mindy is convinced is a meteorite.

Sean, Sydney, Jet, and Carrot head out to view the Northern Lights. Mindy, upset she can't go, gets a boost - Sunspot stays back and agrees to let her be his pet-sitter.

When the kids realize that they all want to use the treehouse at the same time for different activities, arguments break out.

Mindy spots a possible new comet.

Sean sets up an asteroid watch-station in the treehouse.

When Jet realizes that it’s the anniversary of Carrot and Celery’s first date, he wants to recreate that first picnic they had on one of Bortron 7’s moons. The kids all get involved to help create the perfect date night.

The kids rely on an old Earth computer while FACE 9000 is being upgraded.

When a loud thunderstorm hits the neighborhood one evening, the Propulsions are woken up. They gather in the kitchen as the noisy storm rages on, and Jet is too excited to get back to sleep. Carrot, Celery, and Sunspot are sympathetic - they're in the same boat! During the night they all learn about Earth storms as compared to storms on other planets. And then they all try to get Jet to fall back asleep, a seemingly impossible task.

Sydney shows Jet and Sean a cool experiment - dropping different items from the same height to see which reaches the ground first. That reminds Sean of a video he watched of an astronaut on the Moon dropping a hammer and a feather from the same height. They reach the ground at the same time. And the reason is atmosphere - or lack of it - on the Moon. Jet laughs - really? Wait, what's atmosphere? Well, the kids know the best way to find out - into the wagon/saucer! Our kids and Celery fly to the edge of the Earth's atmosphere to learn what it does... and then go to the Moon. Is the atmosphere around the Moon the same as the Earth's? And what happens when our kids do the hammer-feather drop on the lunar surface?

Sydney brings Jet and Sean to the DSA to visit her mom, Dr. Amy Skelley, and check out her work. Dr. Skelley is a robotics engineer who makes outer space robotic and gadget dreams a reality.
