Cute....but is it Mars or the Moon?
Reviewed in the United States on January 14, 2019
My child loves this book and I have read it almost every night. As such for pure entertainment value for budding toddler astronauts it's a winner. One thing that does stand out to me thought is that the artwork suggests that the book was originally about Life on the Moon and then perhaps some editoral/publisher influence pushed to make it about Mars at the last minute since Mars is gets more media time - especially in recent years. In the beginning the ship is travelling to a clearly moon-like orb. You can clearly see Earthrise in the background of the title page art. Mars does not have a crater-pocked landscape like the one depicted nor is it the sky necessarily black.
I think it would've been fine to leave it as a Moon based sci-fantasy story for children - especially if your child is inquisitive like mine and you are now having to try to explain how you can see Earthrise from Mars!
