Kuiper was full of scientific eagerness, because Mars rarely comes so close. Also, he had a brand-new supersensitive infrared spectrometer. With this gadget, he hoped to find out, at least, whether the climate on Mars can support the kind of life we have on earth.
Icecaps & Atmosphere. Mars is considerably colder than the earth. The midday temperature in the Martian tropics rises only a few degrees above freezing. At night it probably falls to - 80°F. But even easygoing earth has living organisms that can stand such extremes.
Unlike the naked moon, Mars has an atmosphere. It is very thin (probably equivalent to the earth's atmosphere 50,000 ft. above sea level), but sometimes small white clouds can be seen floating in it. Yellow dust storms rage across the Martian plains. The Martian poles show white...
Dr. Kuiper thinks that his infra-red spectrometer (a wartime development) has answered some of these questions by identifying certain gases and solids on Mars.
