1969, First edition! "Elementary Research Problems in Space Science". Cover space biology,: build simple astronomical instruments to observe and measure the movements of the moon, planets, etc. Not just for kids - easy science for adults, too. Basic theories, how to build models, instruments, etc. Great for any science class. Too bad Amazon lost all the cool vintage covers again. This is cool. Rare, highly recommended.
