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.

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.

"Total Eclipse of the Sunspot" - While Mindy, Jet, Sean, and Sydney are trying to use a solar panel to improve their energy efficiency, they notice that Sunspot is acting strange. It turns out that Sunspot was aware of an impending eclipse and was trying to alert the kids to the fact that the Sun would be darkened for a while. Curriculum: A solar eclipse is a type of eclipse that occurs when the Moon passes between the Sun and Earth, and the Moon fully or partially blocks the Sun. In a total eclipse, the disk of the Sun is fully obscured by the Moon. It's important not to look directly at the Sun during an eclipse, but you can watch it through the use of a box viewer. "Sean's Year in Space" - Sean is excited by NASA's "Year in Space" program on the ISS, and decides to try to live for a year in the tree house without ever coming down. The kids keep interrupting him, and finally, after only a short afternoon of trying, he comes down for dinner. Curriculum: The International Space Station, or ISS, is home to several astronauts at a time, who come and go in small capsules like the Soyuz. At this point, astronauts are even staying for a year at a time to study what happens to humans who live in micro-gravity for extended periods, so we can learn what will happen to us on long space voyages, like a trip to Mars.

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!

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.

"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.

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.

"Beep and Boop's Game" - The kids help Dr. Rafferty and Bergs get Mars Rover BOOP over a ravine on the red planet by simulating actions in the DSA "Mars Yard" using BEEP (Boop's sister)! Trial and error leads to success. Along the way, the kids learn just how scientists communicate with far away rovers - through satellites above Mars. The kids then solve a new mystery set up by Bergs, figuring out that Beep and Boop are communicating about... a game of Mars/Mars Yard tic-tac-toe they're playing! Curriculum: A good amount of communication between Mars and Earth goes through satellites. Rovers send images, along with instrument and status data, back to Earth. Extrapolating from the data, the scientists send commands to the rover, which can take 4-24 minutes to be received due to the distance. Rovers are often on their own, carrying out commands and sending image data to overhead satellites. The rover's commanders may tell it to move toward a new rock, grind a rock, analyze a rock, take photos, or gather other data with other instruments. "Constellation Prize" - When Mindy thinks she's found her own star, the other kids explain how stars are labeled and identified by constellations. Mindy eventually learns that she hasn't found a new star, but that she CAN create her own version of a constellation by connecting patterns in the sky. Curriculum: A constellation is a group of stars that make an imaginary shape in the night sky. In different parts of the world, people have made up different shapes out of the same groups of bright stars, like a game of connect-the-dots. In the past, constellations were useful for navigating at night and for keeping track of the seasons. They are now useful for identifying parts of the sky astronomers are studying. Because all the stars are at different distances, the constellations would look totally different to inhabitants of another planet orbiting another star.

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.

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.

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!

Mindy's mom has gradually been giving Mindy permission to go a little bit farther in the neighborhood on her own, and Mindy is trying to map out exactly what her boundaries are. Sean compares her "Mindyspere" to the helisophere-the boundaries of the Sun's influence. The kids get Celery to fly them out past the heliosphere into true interstellar space. Back on Earth, they make their own Voyager 1 (out of a wagon) and take Mindy to the outermost edges of the Mindysphere! / Sydney knows a lot about Boxwood Terrace's early history, and she tells Jet stories about a local pioneer who went by the nickname "Lone Star." He got that name because he was an early astronomer who liked the hills of Boxwood Terrace for their excellent views of the night sky, and built the first Observatory on the hill that now sits at the center of the Deep Space Array. As Jet imagines Sydney's story of Lone Star, the kids turn the story into a Western-flavored musical.

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!

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.

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.

Jet, Sydney, Sean, and Sunspot join Celery as she competes against her brother, Uncle Zucchini, in an "Earthie-style race with a winner"! The race is tight until Celery uses the kids' proposed secret "strategy" - a "gravity assist" off of Jupiter, to increase their saucer speed, and win! / Jet uses his Bortronian skills to test his first experimental Time Machine so he and his Earthie friends can go back to an exact time - 3 minutes earlier - in order to see a spectacular moment in a meteor shower that they missed. A mistake happens the first time, so he keeps trying to go back in time to fix the first mistake, but more mistakes keep happening and snowball into hilarity.

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!

Mindy's mom has gradually been giving Mindy permission to go a little bit farther in the neighborhood on her own, and Mindy is trying to map out exactly what her boundaries are. Sean compares her "Mindyspere" to the helisophere-the boundaries of the Sun's influence. The kids get Celery to fly them out past the heliosphere into true interstellar space. Back on Earth, they make their own Voyager 1 (out of a wagon) and take Mindy to the outermost edges of the Mindysphere! / Sydney knows a lot about Boxwood Terrace's early history, and she tells Jet stories about a local pioneer who went by the nickname "Lone Star." He got that name because he was an early astronomer who liked the hills of Boxwood Terrace for their excellent views of the night sky, and built the first Observatory on the hill that now sits at the center of the Deep Space Array. As Jet imagines Sydney's story of Lone Star, the kids turn the story into a Western-flavored musical.

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.

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.

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.

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.

"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!
