Curriculum: There are different kinds of stars, which emit different kinds of light.

"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.

How Come the Moon Changes Shape? - When Jet, Sydney, and Sean have a hard time trying to explain the phases of the Moon to Mindy, Jet's parents, Celery and Carrot, offer to fly them out to space so they can see how the Moon changes shape depending on perspective. Curriculum: The Moon changes shape depending on its position relative to the Earth and Sun.Night of a Bazillion Stars - Jet, Sydney, and Sean decide to have a sleepover in Jet's backyard. 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.

"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!

"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).

"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.

"Which Moon is Best?" - Sean wants to be the first to walk on a moon, like his hero Neil Armstrong. When Sydney points out that 12 astronauts have already walked on our Moon, Sean thinks that rather than be the 13th to walk on OUR moon, why not be the first to walk on ANOTHER moon in our solar system? Sure, but which moon? The kids decide to compare the frozen moons Europa, which orbits Jupiter, and Enceladus, which orbits Saturn. They get help from Carrot and Celery, who fly them to each one, and Sean gets to walk on them. Curriculum: The gas giants Jupiter and Saturn each have around 60 moons - each of them unique. Interestingly, each gas giant has a frozen ice moon that contains a warmer liquid ocean under the surface: Jupiter's moon Europa, and Saturn's moon Enceladus. Each moon has its own similarities and differences."Detective Mindy" - When Mitchell's mother declares the kitchen counter a "black hole" because she can't find her sunglasses and she's sure she left them there, Mitchell takes up the case of the black hole kitchen counter. As he's investigating, one by one, all the other kids get involved in his process. As they learn about what a black hole really is, Mitchell discovers that science holds enough mysteries to keep him busy for many years. Curriculum: Black holes are strange little holes in space that are like vacuum cleaners that use gravity (instead of suction) to suck things in. A black hole is what remains when a massive star dies. They send out no light and have very strong gravity. Once a planet or star has been sucked into the black hole, it cannot escape, and compresses to a very small size.

"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.

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.

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 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.

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.

Jet takes the kids on a saucer tour all around the Earth to discover all the ways that water can be found. They visit Antarctica to look at the ice, and then compare that extreme to the icy surface of Jupiter's moon Europa. / Sydney wants to enter a Commander Cressida story contest, but can't think up a good enough story. The other kids help, and they come up with a story about lassoing a comet to bring water to Venus, and then Mars.

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! Curriculum: Enceladus is a small moon of Saturn that contains a liquid ocean underneath an outer layer of ice. It has "ice volcanoes" that shoot geyser-like jets of water vapor into space. Some of the water vapor falls back as "snow" and the rest escapes, which supplies most of the material making up Saturn's E ring. 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. Curriculum: Gravity is an invisible pulling power that every object has-planets, moons, stars, and YOU. Gravity pulls all objects in the universe toward one another. The bigger and heavier an object is (the more mass it has), the more gravity it has.

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.

Mindy has finally turned five and is super excited that she is now old enough to go to space. But she's planned a tea party in the back yard.
