As the kids get ready for Valentines Day by making their own valentines out of paper, Mindy continues to feel sad that little, frozen Pluto is so far out at the edge of the solar system. When Sydney shows Mindy a newly-downloaded, full-color image of Pluto as seen by the New Horizons spacecraft, Mindy is intrigued by Pluto's "heart" of ice. Mindy once again feels that Pluto deserves our love, since it's no longer considered a planet, but is orbiting out there at the edge of our solar system, like a big frozen Valentine. She asks Sydney to bring her own little hand-made Valentine to Pluto on her behalf. Sydney leads an expedition of the kids to Pluto to bring Mindy's Valentine, experience the frozen dwarf planet themselves, and bring back their report to Mindy. / Sydney is directing the kids in a backyard movie, making her version of a Commander Cressida story about the formation of a star. The other kids all have parts, but Sunspot has the lead - as the star! The kids' movie coincides with the celebration of a star being born near (a.k.a. 10 light years away from) Bortron 7!

"Sunday Drive" Parts 1 & 2 - After the Propulsions download their new version of their saucer dashboard operating system, things are out of whack. Their test drive to Mars - usually a simple trip - is complicated by the new dashboard. They zip to Venus and Saturn instead... and then finally land on Mars, so they think. They're actually in an Earth desert, Mars-like at first (hot, red soil, lack of water), but soon they realize where they are. A desert vs. Mars comparison is made. Before heading home, the family decides that the old, dependable saucer operating system works just fine for them. Curriculum: An Earth desert and a Mars desert have some similarities, but are also very different. A comparison is made between the two, including life or lack thereof, temperature, water, and soil.

"Space Junk" - After learning about space junk, the kids are determined to help do their part to clean up their "space neighborhood." They meet up with Uncle Zucchini, a long-time galaxy garbage man! Using Bortronian technology, they start a cleanup. During the course of the day, our kids learn that recycling is necessary both on Earth and in space! Curriculum: The outer space region around Earth swarms with millions of pieces of man-made space junk that create potential hazards. Objects as small as 4 inches can be seen by radar or optical telescopes on Earth. Cleaning the debris is a challenge. Trips to larger objects could remove them from orbit, but that's expensive. Another proposal is using lasers to provide a path-changing push that wouldn't damage the object. "Scientific Sean" - Jet is fascinated by Earth paper airplanes when he watches Sean casually fold one. Jet suggests that the kids challenge each other to build the plane that will fly the farthest, and still carry the payload of a message. Sean wants to use the Scientific Method to solve the distance/size issues. CURRICULUM: The Scientific Method is a simple set of rules that scientists use the world over, to make sure that they are doing their experiments correctly and in a way that they can repeat. But great science comes from both the application of this simple set of rules AND from imagination and inspiration.

"Tiny Blue Dot" - A rollicking, song-filled recap of the Propulsion family's mission to Earth - as intergalactic travel writers, they really know their way around the Milky Way, and know the difference between a lovely, livable "Goldilocks Planet" like Earth, and the other, way less-livable planets! Curriculum: The Earth is a very rare and wonderful planet in the vastness of space, with its ideal size, its distance from its sun, its breathable atmosphere, liquid oceans, and ability to sustain life. "Earth Camping" - Mr. Petersen and Mitchell go camping with Carrot and Jet. The two dads have opposite approaches to setting up tents and preparing food, but when the dads get off track during a hike, the boys help them all find their way back using the compass, and the skills they've learned from their dads (turns out the kids were paying attention all along!). Curriculum: We can find our place outdoors by understanding how to find direction - north, south, east, and west. The Sun rises in the east and sets in the west. A compass uses the Earth's magnetic field to find which way is north (the small magnet inside the compass is drawn by the Earth's magnetism to point to the north pole).

The kids get information from Dr. Rafferty and then travel to outer space to confirm the amazing fact that there is no sound in outer space... even though Jet is convinced he's heard sounds all over the solar system. / After Mindy laments the fact that she's still only 4 and still can't go to space with the other kids, Sydney, Jet, Sean, and Sunspot plan a full makeshift, cobbled together "Day in Space" right there in Jet's yard. Mindy's day ends on a nearby hilltop where they all watch a real, amazing, actual space event - the Leonid Meteor Showers shooting across the sky!

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.

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.

How Come the Moon Has Craters - The kids take a trip to the Moon and learn that falling asteroids probably created all the craters on the Moon's surface! Curriculum: Craters on the Moon were probably caused by asteroids hitting the surface. Backyard Moon Base - Led by Sydney, the kids build a moon base in Jet's backyard and use their imaginations to figure out what challenges they would need to overcome in order to live on the Moon. Curriculum: A moon habitat is a structure on the Moon that would provide the right conditions to allow humans to live on the Moon's surface.

Sean's nervousness about flying out to visit the remote Neptune is soothed by Jet's suggestion - an improvised, fun "Neptune tune." It works as our kids, Sunspot, and Celery fly to the faraway eighth planet! / When the kids discover that they've missed all 63 of Jet's Bortronian birthdays, they decide to celebrate the one-year anniversary of him landing on Earth instead... with an "Earthday birthday" surprise party!

It's Mothers Day, and Jet wants to do something special for Celery, who just wants to finish her book. She suggests a day where Jet finds his own missing things. Jet agrees it would be the perfect gift, but first he needs her to fly them to Mars, so he can find his missing robot, Jet 2, that he left there! It's the first windy day of spring at Boxwood Terrace, and the kids are all trying out their new kites - all but Sean, who's stuck in his room with a cold. Sunspot joins Sean and helps him work out engineering problems so he can entertain himself - and even fly a kit from his room!

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!

"Round and Round" -The kids learn how all the planets both orbit around the Sun and rotate on their own axes at the same time. Curriculum: The planets both revolve around the sun and rotate on their axis. "The Plant From Bortron 7" - Jet attempts to grow a seed from his home planet, but the light from our Sun is stronger than the light from Bortron 7, and has a surprising effect on the plant! Curriculum: There are different kinds of stars, which emit different kinds of light.

Jet pitches an idea for the annual Boxwood Terrace Christmas Pageant, and not only is it accepted, he gets to direct it! He casts Sean, Sydney, Mindy, and Sunspot as characters in the play, and hires Mitchell Petersen to help him find this elusive thing called "Christmas Spirit." / Jet is looking for the Spirit of Christmas, something intangible that Sean and Sydney can't quite define. Mitchell wants to belong to the group, but doesn't know how to do it. Both kids get their answer in a heartfelt conclusion.

"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 needs to climb one more mountain to join an elite space climbing club - and the mountain happens to be Mt. Sharp, on Mars! Jet convinces the kids to fly to Mars with Sunspot and join the mountain climbing expedition. With all the Earthie kids away for the day, Jet and Sunspot are left to their own devices. They notice neighbor Mitchell digging for buried treasure in his yard, and decide to make and bury their own treasure, then make a map that Mitchell can find and follow to their homemade treasure!

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. Celery takes the kids on a quick trip to space to see what causes a lunar eclipse. Meanwhile, Mitchell Petersen is on the case to figure out what exactly is going on with that strange Propulsion family... / Sydney, Sean, and Mindy take Jet trick-or-treating, and along the way, they learn about the Red Moon effect from some of the neighborhood scientists. Carrot and Celery turn their garage into a haunted house, which is an unexpected hit with the neighborhood. Jet and Sunspot even make Mindy's Halloween wish come true by flying across the Red Moon as a witch and her cat on a broom.

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.

"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. Curriculum: The sun is a star. Our sun is a star in the Milky Way galaxy, a yellow dwarf. The Propulsion family comes from another star in our galaxy: Bortron, a smaller, cooler red dwarf star. "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! Curriculum: An observatory is a location used for observing terrestrial or celestial events. A telescope is an instrument that aids in the observation of remote objects by collecting electromagnetic radiation (such as visible light).

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!

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.

"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!

The kids observe the full Moon at night and wonder why it seems to have a "face." They research why the light and dark splotches seem to make a face, and ultimately decide to fly to the Moon's surface so they can see for themselves what the light and dark splotches are made of. The kids are digging again down by the Lake, and dig up a part of an old rocket. This leads Sydney to tell another "Lone Star" story, this one about how long ago, when Boxwood Terrace was called "Boxwood Territory," early astronomer Lone Star engineered and built the first rockets. This inspires the kids to engineer and build their own "foot rocket."

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. Celery takes the kids on a quick trip to space to see what causes a lunar eclipse. Meanwhile, Mitchell Petersen is on the case to figure out what exactly is going on with that strange Propulsion family... / Sydney, Sean, and Mindy take Jet trick-or-treating, and along the way, they learn about the Red Moon effect from some of the neighborhood scientists. Carrot and Celery turn their garage into a haunted house, which is an unexpected hit with the neighborhood. Jet and Sunspot even make Mindy's Halloween wish come true by flying across the Red Moon as a witch and her cat on a broom.
