The incomparable creator of this pioneering series, who will be sadly missed by all young scientists, extends an invitation and sparks the imagination as he authors another outstanding title in the Lets-Read-and-Find-Out Science series. He begins: “In this century, you may become the first person to walk on Mars.” What would the journey be like? How would you get there? What would you take with you? How would you survive on the planet? He explains with brief, simple text, using what scientists know about the planet and extrapolating from previous space explorations. He uses photos from NASA to explain surface conditions, give facts about gravity, and proof that there was once water and could be still. Kelley (Three More Stories You Can Read to Your Cat, p. 341, etc.) provides meticulous pen-and-watercolor drawings that show men and women aboard the space ship, setting up the Mars station, and moving along the rocky terrain of the planet. Double-page spreads of the red-orange landscape and rocky surface are especially captivating. The author concludes with more facts about the planet and a Pathfinder photograph of Mars on which various rocks are named. A book to give young explorers goosebumps. (Nonfiction. 6-10)
