From School Library Journal
Gr 2–5—Leo Geo is back in another science-based adventure, joined by his brother, Matt Data, in a nifty flip-over format. Leo learns that a large comet is on a collision course with Matt's orbital science facility and blasts off to save his astronomer brother. When Fizzcom, his supercomputer, malfunctions, Leo must survive a black hole, space pirates, and a crash landing before he can stop the comet and be reunited with his sibling. On the flip-side of the book, Matt finds out that Leo's computer has a bug and sets off with his genius dog, Maff, to reboot it. Matt and Maff share information about satellites, comets, and other astronomical bodies they pass on their way to the remote broadcast station. When Maff is kidnapped by space pirates, Matt uses his scientific knowledge to get her back and to finally find Leo. Science, adventure, and comics are perfectly blended in this kid-friendly story. The bright, detailed, full-page panels are covered with strange creatures and planetary objects that will catch and hold young readers' attention, and the scientific information is simply presented and well-integrated into the dialogue. The varied layout of the pages, vertical and horizontal, and the "search engine," a hunt for specific objects throughout the book, encourage engagement with the story. This is a great offering for graphic-novel enthusiasts or kids looking for a fun read.—Marian McLeod, Convent of the Sacred Heart, Greenwich, CT
Leo Geo is happily puttering around the Fizzmont Institute for Rad Science when he gets some alarming news from his trusty computer, Fizzcom: a comet is headed right to the Fizzmont Orbital Science facility, where Leo’s brother, Matt Data, lives! Determined to rescue him, Leo hops in his spaceship and sets out to help his bro. Meanwhile, at the other end of the book, Matt Data has detected a fatal error in Fizzcom’s programming: soon he will malfunction and start performing bad experiments instead of rad experiments. So Matt sets off in his spaceship to save Leo from his renegade computer. Where do they meet? Right in the middle, naturally. But not before explaining propulsion engines, supernovas, and a handful of other science concepts, all while battling space pirates (of course). Chad’s frenetic and lushly colored illustrations depict Matt’s and Leo’s riotous romps through space as a universe of tiny details swirls around in their wake. Another rollicking, playful science adventure, following Leo Geo and His Miraculous Journey through the Center of the Earth (2012). Grades 3-6. --Sarah Hunter

Here are some examples:
- astronaut centrifuge: the simulated gravity is toward the outside, not down to the ground. Rotate the car 90 degrees and it's right.
- the Space Shuttle used liquid HYDROGEN as fuel, not nitrogen.
- rocket stages have traditionally been thrown away, disintegrating from atmospheric forces on re-entry into the atmosphere and falling as mangled debris into the ocean. Shuttle solid boosters were recovered, but they were an extreme exception and were very hard to refurbish. SpaceX is working on landing a booster, but on a dry surface. Salt water does enormous damage to rockets and spacecraft.
- ISS orbits at 400km/250miles altitude
- several key components of ISS were constructed by Russia and delivered by their rockets, not by Shuttle
- at the most distant point in its orbit, the Moon is 251,351 miles from Earth, not 235,000
- the side of the Moon that points away from Earth is the FAR side, not the "dark" side. There is nothing darker about that side that the one that faces Earth. Perpetuating this misnomer does a disservice to children.
- the gravitational force at the event horizon of a black hole is a function of its size. It can be comparatively low.
- gravitational compression in a black hole makes things occupy less space, it does not magically turn them into "a couple of molecules"
- The Moon's gravity is 1/6 that of Earth, not 1/11, so you could jump six times farther on the Moon, assuming you were not wearing a space suit.
- freezing a comet would make it cold, not cause it to stop moving. Its momentum would be unaltered by its change in temperature.
Well, that's half the book. I'll leave you to sort out the other half!
