"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).

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.

"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).

"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.

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!

They use Sean's telescope to look at the night sky and learn why stars twinkle and planets don't. Curriculum: Star and planet gazing. Stars twinkle because of turbulence in the atmosphere of the Earth. Planets do not twinkle the way stars do.

"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.

Curriculum: Force is any interaction that tends to change the motion of an object. Force can also be explained as a push or pull.

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! Curriculum: Mars has deeper canyons than our own Grand Canyon on Earth. The deepest canyon in our solar system exists on Mars, called Valles Marineris.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! Curriculum: Our sun is actually a bright star out on a spiral arm of the Milky Way Galaxy, which is made of billions of other stars, and our galaxy is just one of billions of galaxies.

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? Curriculum: The next big frontier for human space flight is Mars. We have long range plans to get humans to Mars, but still have not solved some of the challenges, like what human inhabitants will do about the lack of oxygen and water, and the extreme temperatures.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. Curriculum: Sound travels in waves like light or heat, but unlike them, sound travels through vibration. So, in order for sound to travel, there must be something for sound to travel through. Sound can travel through air, water, and solid objects, but not through space.

"Mission to the Moon" - Sean tells Jet, Sydney, and Mindy about the Apollo 11 mission, and the kids decide to do a real-life reenactment of man's first mission landing on the Moon!

A Visit from Uncle Zucchini - Celery's brother, Zucchini, and his pet, Moonbeam, decide to visit the Propulsions, but get lost along the way. The kids have to figure out where on Earth he is. As it turns out, Uncle Zucchini never made it to Earth, but has landed on a place that sort of resembles Earth - Titan, Saturn's largest moon! Titan has Earth-like features such as oceans, mountains, and an atmosphere. Curriculum: Titan is Saturn's largest moon, and the second largest in the solar system. Titan has lots of conditions that make it similar to Earth, including an atmosphere with clouds and a golden haze, and liquid oceans.Mindy's Weather Report - Mindy and Sunspot, watching a weather report broadcast on FACE 9000's screen, learn of a huge storm system on Saturn. When the other kids hear about it, they mistakenly assume the storm is somewhere local. Mayhem ensues as the misinformation spreads and everyone rushes around to prepare, while Mindy meanwhile "broadcasts" her own weather report from Jet's house. Curriculum: Earth is not the only planet with storms! Although we have big hurricanes here that typically last up to a week, Saturn is home to a hexagonal group of hurricanes locked into place around Saturn's north pole, that may have been going on for hundreds of years.

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. Curriculum: Saturn has more than 12 rings that are made of mostly ice. The ice pieces range from microscopic to very large chunks. The rings appear to be revolving with Saturn at the same speed but it's thought that the individual rings revolve at different speeds.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. Curriculum: The North Star is often used for navigation due to its constant position in our sky. It isn't the brightest star, but unlike the other stars, it seems to remain at a fixed location in the sky.

"A Kid's Guide to Mars" - Celery and Carrot need to update their guidebook about Mars, and the kids join them on a trip to see how much things have changed on Mars in the last four billion years. Curriculum: Mars was once (4 billion years ago) a lot like Earth, with oceans, clouds and drinkable water. Something happened 3.7 billion years ago that turned Mars' atmosphere from warm and wet to dry and cold."Jet 2" - Jet builds a robot version of himself, so that he can be in "two places at once!" But Jet learns what jealousy is when the other kids seem to be having more fun with Jet 2 than they are with him! Curriculum: A robot is an automatic mechanical device often resembling a human or animal. Humans build robots to perform the tasks humans can't do, but people are still in control because they give instructions to the robots.

"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.
