Grade 4-6-Actually a physical portrait of two planets, this survey draws illuminating parallels and contrasts between the history, structure, and current state of both Earth and Mars. Imparting a vivid sense of how inhospitable the red planet is, at least to life as we know it, Ride and O'Shaughnessy supply a lively mix of sweeping claims ("Mars has the largest volcanoes and the longest, deepest canyons in the entire solar system"), specific observations, and logical extrapolations. The authors' comments are enhanced by a generous array of computer graphics, precisely detailed paintings, and recent photographs from both space and ground level. The material includes information gathered from the 1997 Pathfinder mission and a mention of the Mars Climate Orbiter, though not of the latter's failure. The book is capped by a time line of Mars missions through 2001 and a well-chosen list of Web sites, making it a good, if already dated, replacement for any book on this subject more than two years old.

Although the fate of the latest mission is still unknown, contemporary fascination with Mars remains unabated. In this third collaboration for children, Ride and O'Shaughnessy offer an excellent introduction to the red planet. "Earth and Mars share a common beginning. But the two planets evolved very differently," they write. "Why did Mars follow one path while Earth followed another?" Jumping off from this central question, the authors offer factual comparisons between the two planets, interspersed with information on the exploration of Mars, and historical background on those who believe the planet has supported life. The book's visuals are stunning: photographs taken from space pop off the black pages, and there are charts and sophisticated artist renderings throughout. A concluding "Mars Mission Time Line," with a listing of Web resources, rounds out a fine resource for young ones with Martian fever.
