“The precocious narration...coupled with Astro’s arch speaking style...is great fun to read aloud, and fellow newcomer Woodard’s Jetsons-esque style and bright palette bring just the right Space Age atmosphere to the story.”

– Publishers Weekly

"Informative, dynamic, rich in vocabulary, and quite funny."

– Kirkus Reviews

"On the first read-through, some of the physics involved may be a bit complex for younger readers, although a spread of “Space Facts” at the end will help clear up lingering questions and perhaps pique the interest of would-be scientists. But this won’t keep even the most science-averse young readers from enjoying the unamused Astro’s voyage through the galaxy, or from demanding another read."

– Booklist

"A fun story for adventure seekers and space fans."

– School Library Connection
