Ready Jet Go!

"More than One Moon"- 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. "Visit to Mom's Office"- 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?

"How We Found Your Sun"- Jet explains how his family, the Propulsions, found Earth by way of the Sun, a star in the Milky Way galaxy. Celery takes the kids out into space and shows them how the Sun looks huge, or small like other stars, depending on your perspective."Treehouse Observatory"- 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!

"Beep Has the Blues"- Beep is sad because her sister rover on Mars, Boop, is sick and can't move. Celery flies the kids out to Mars to try to help and discover the problem - that Boop's solar panels have been covered in dust. "Chore Day"- Jet learns what chores are, and he and Sean help Sydney turn her chores into science games!

"Mission to Mars"- When Jet and Sydney interrupt Sean doing some training in his backyard to eventually lead a mission to Mars, Jet suggests they just have his mom fly them out to Mars. Is Sean's concern about Martian dust devils legitimate? "Sounds Abound"- Sean is trying to work on a science project for Space Troops, but is interrupted by his friends' constant noise. His search for a quiet place to conduct his experiment leads him to the realization that sound is exactly what his experiments needed all along.

"What's Up with Saturn's Rings?"- Celery takes Jet, Sydney, and Sean on a trip to explore Saturn's rings to learn what they're made of. "Sunspot's Night Out"- When Sunspot goes missing in the neighborhood, Sydney, Sean, and Jet use the North Star to navigate their way to where he is.

"The Grandest Canyon"- When the Propulsions are forced to watch a slide show of the Petersen's vacation to the Grand Canyon, they're inspired to take their own trip to Mars to explore Valles Marineris-the largest canyon in the Solar System! "A Visit to the Planetarium"- Sean and Sydney take Jet to the DSA to see a show at the Planetarium. But things take a fun turn when Jet decides to upgrade the show with some Bortronian technology and sings a song explaining how to find Earth in the Milky Way galaxy!

"Ice Moon Enceladus"- 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! "What Goes Up..."- 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.

"Comet Fever"- The neighborhood is having a star gazing party when Mindy discovers what may be a new comet. While Celery takes Jet, Sean, and Sydney out to space to get a close-up look at the comet, Carrot and Mindy decide to surprise the others and make their very own comet in the backyard using ingredients from home!/"Asteroid Patrol"- When Sean learns that asteroids are floating around the solar system (potentially), he decides to set up a homemade asteroid watch-station in the treehouse, and gets all the other kids involved. Eventually, Sean's mother and her colleague at the DSA help Sean and the others understand how scientists monitor the skies for asteroids, a job that Sean doesn't need to do all by himself.
