After an afternoon on the Moon, Celery, Jet, and Sunspot discover, as they fly to Earth, that they have mistakenly left Carrot on the Moon! Then the saucer malfunctions and they receive news of a possible solar storm headed their way. In a nail-biter, Jet and Sunspot do a mid-outer space repair job - as per Celery's instructions -with Carrot comically adapting to the Moon environment. In the end, the saucer is fixed, Carrot is rescued, and the solar storm heads in the opposite direction of the Moon. / 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. They use more and more absurd methods, until Celery has a conventional Earthie solution: sing a lullaby.

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!

"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. Curriculum: There is more than one moon in the Universe; in fact, there are hundreds of moons in our own Solar System. Mars has 2 moons, Phobos and Deimos, which are unusual in that they are not round like our moon, but oddly shaped, like battered potatoes. "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? Curriculum: An exoplanet is a planet that doesn't orbit the Earth's sun, but instead orbits a different star in the Universe.

The kids and Sunspot attempt to build the tallest tower ever on the Moon, hoping to beat Jet's cousin's record. While building, the Moon's surface shakes. Huh? The Earth kids are amazed to learn that the Moon has quakes, and Jet is just as amazed to learn that Earthquakes exist. After learning about the causes of moonquakes, the kids attempt to build a Moonquake-proof structure. / Sean and Sydney are planning to take Jet to the DSA Open House the upcoming weekend. The Earth kids are nervous that he will get in front of a crowd of strangers and forget to keep the secret that he's an alien from Bortron 7. After a hilarious outburst from Jet, the kids are motivated to try to "train" him to behave less like an alien from outer space, and more like a "regular Earthie kid." Jet's doing well until he ends up using his Bortronian jet-pack to fly up to rescue the DSA weather balloon when it's about to get away in some bad weather.

Sydney, Sean, and Mindy help Jet experience his first Halloween. They come up with a list of classic Halloween to-dos, including carving Jack-o-lanterns, dressing up in costumes, and collecting candy.

"What's a Satellite?" - An Earth-orbiting "telecom" communications satellite breaks down, and satellite TV service in Boxwood Terrace stops working. Three people can't watch their favorite shows and consequently get very upset. Jet decides to fly up to space and see what the problem is with the satellite, and hilarity ensues. Curriculum: A satellite is an artificial object that has been intentionally placed into orbit. Satellites are used for a large number of purposes. Communications satellites receive signals from Earth and bounce them back to other locations, for everything from GPS to cell phone service to TV shows. Satellites are usually semi-independent computer-controlled systems. "Satellite Selfie" - The kids learn that they can use links to different websites to see a satellite view of their house. Mindy notices that Jet's house is not in the image. That's because these images are from sometime over the past 2 years, and not live images from space. With Dr. Rafferty's help, the kids identify the next time a satellite will pass over their neighborhood, and try to gather for a "space selfie" next to Jet's house. Curriculum: Satellites are objects that humans have placed into orbit around the Earth. Many have cameras in them. Some of these satellite cameras look "up" at the outer areas of space, and some look "down" at the Earth - they can even see our houses and cars!

Carrot is about to turn 250 Bortronian years old, and the kids have set up a backyard circus to help him celebrate. They all notice that Earth's gravity makes it hard to perform their circus stunts, so they take the whole circus to the Moon, where its 1/6th gravity makes all their stunts much easier! It's Earth Day, and the kids are preparing posters for the big community celebration at the DSA. They decide to research their posters by traveling all around the Earth in Jet's family saucer and observing all the things that make Earth so special.

Date Night - 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. Curriculum: It's hard to have a picnic anywhere in the Solar System besides Earth - here we're not too near or too far from the Sun, so the temperature is just right, plus we have liquid oceans and a breathable atmosphre. Anywhere else, you'd definitely have a hard time enjoying a picnic outdoors. Face on the Fritz - When the kids are trying to build a new pet house for Sunspot and FACE 9000 gives them mixed-up directions, they learn that it is time for FACE 9000 to get upgraded. In the meantime FACE 9000's "substitute," the "DATA-BOX," is an old Earth computer from the early 1980s. The kids need to learn how to give instructions in the way computers understand, putting them in charge of using technology in an active way. When FACE 9000 comes back, they have learned to appreciate him, as well as to be more independent thinkers. Curriculum: Technology has advanced greatly since the days of the giant computers that guided man to the moon in 1969. However, even though technology is very useful, it is still a tool, not an end in itself, and people still need to know how to monitor and program it.

They end up hanging out with her before her DSA meeting. They solve an engineering problem together, which inspires Ellen to use the same solution with the engineering project at the DSA.

"Just the Right Distance From the Sun" - 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"! Curriculum: All life on Earth comes from the energy of the Sun. The Earth happens to be located just the right distance from the Sun: not too far away, and not too close. This makes the Earth what we call a "Goldilocks planet": not too hot, not too cold. "Solar Power Rover" - 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. Curriculum: The Sun creates solar power that is used for energy. Solar power is the conversion of sunlight into electricity, either directly or indirectly.

Sunspot begins acting strangely, and Jet fears that he is sick. Carrot and Celery examine him, and decide that he's acting strange because of a large sunspot on the Sun. The only way to cure him is to bring him to the Sun, and get him close to the huge sunspot. Mindy wants to have a sleepover outside with her friend Lillian, but it's winter and too cold to sleep outside under the stars. Sean points out that they are under the light of a star all the time - our Sun! Mindy learns that our Sun is a star, just like the tiny ones we see at night.

"Tour of the Solar System" - 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. Curriculum: The sun is at the center of our solar system, and everything else revolves around it. The sun, planets, dwarf planets, moons, and different kinds of space rocks like asteroids and comets are all part of our solar system. "Jet Cooks Dinner" - 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. Curriculum: "Failure is not the opposite of success; failure is a stepping stone to success." This attitude can be applied to cooking as well as scientific discoveries!
