ARTIFICIAL SATELLITES: Helpers in Space

In the ""Early Bird Astronomy"" series, an introduction to satellites for the K-2 crowd: what satellites are, what they look like, how far above the earth's surface they are, how they communicate with earth, what they do. An adequate introduction, but curiously short on some details: How big are they? How much do they weigh? How complex are their electronics--like a TV set? Some inadvertent anthropomorphism: Satellites don't really ""observe"" and ""watch""--they record information and transmit it to earth; people watch. Attractive, simply captioned paintings augment the text. Index.
