Meteor, the star of Mousetronaut (2012), is excited to accompany other astronauts on a six-month mission to Mars. He has exercised, studied, and eavesdropped until he feels more than ready to take on this new challenge. So when the names of the multiethnic and multigender crew are announced, he is shocked and disappointed to learn he is not among the chosen. Undeterred, he manages to slip onboard and hides away for the duration of the flight to the Red Planet. When a problem arises that can potentially end the mission, Meteor comes up with the solution and, of course, saves the day. Large, delightful mixed-media illustrations combine realism (Mission Control) and cartoon (Meteor lifting weights, packing his suitcase, and floating through the cabin). A four-page afterword by the author tells the history of and the potential for the exploration of Mars. Children will enjoy the tale of how the smallest member of the crew becomes a national hero in the yearlong journey.

Kirkus Reviews

When NASA announces the crew of the upcoming Mars mission, Meteor the Mousetronaut is, shockingly, not on the list. No matter; the little mouse isn't about to let his training go to waste. He packs his spacesuit and stows away on the Galaxy, floating out to scavenge crumbs while the human crew sleeps. After six months, the Galaxy reaches Mars orbit--but one of the landing craft's engines fails, and the remaining one isn't strong enough to transport even one human. Meteor volunteers for duty and, equipped with a tiny American flag, descends to the Red Planet to gather rock samples. Six months later, he returns to Earth to be welcomed as a hero with the other astronauts. While this story inevitably lacks the freshness of Meteor's debut (Mousetronaut, 2012), Kelly's prose and storytelling have matured, and Meteor's enthusiasm is as infectious as ever. Payne's delightfully regular-looking, multiethnic and gender-inclusive crew displays the same winning combination of heroism and lumpiness (the mission commander has an endearingly potatolike face) that distinguished the first adventure. Perhaps what's most striking about this book, though, is the four-page afterword, in which Kelly summarizes the history of Mars exploration and discusses the potential for a real manned mission. His eloquence in advocating for a vigorous space program bespeaks both passion and experience. Rodent or no, Meteor sure is one heck of a space ambassador. (Picture book. 4-8)

K-Gr 3 Introduced in Mousetronaut (S &; S, 2012), pint-size ace Meteor is back, secretly training for America's first human mission to Mars. When he doesn't make the crew list, he stows away and carefully stays hidden as he observes onboard life during the six-month journey to the red planet. Once in orbit, a failed engine means the landing will be scrubbed-the one remaining engine isn't strong enough to carry a human. That's when Meteor offers his small self as mission savior and becomes the first mouse on Mars. Payne's signature mixed-media artwork is realistic yet playful and gives readers a glimpse into space flight with excellent use of spreads. The themes of persistence and how immaterial one's size is are strongly present and will resonate with children. The four-page afterword discusses the history of Mars and mankind, what a flight to Mars would entail, and the benefits of space exploration, and offers details about the planet. While preschoolers will enjoy the tale, the afterword also makes this title perfect to share with primary-grade students in units on planets and space exploration.
