Space Explorer 3: Exploring Mars and the Inner Planets

They're all made of rock and they're all relatively close to the Sun, like the Earth –but Mars, Venus and Mercury couldn't be more different worlds. On tiny Mercury, you just as easily freeze as get fried, on Venus, the atmospheric pressure would crush you long before you reached the searingly hot surface, and on Mars you might just have a chance – so long as you protected yourself from long-term exposure to deadly cosmic rays. Book 3 in the Space Explorer series surveys each planet in detail and looks at what we've learned from our extensive exploration of Mars.
