Many a scientist's fond hope that there was life on Mars was dashed in 1963 when spectrographic studies revealed that the Martian atmosphere is as much as 50 times thinner than the earth's. It seemed almost certain that a relatively weak Martian gravity had allowed most...
In a paper presented to an American Chemical Society meeting in San Francisco, Jet Propulsion Laboratory Astrophysicist Lewis Kaplan disclosed that spectrograms of the Martian atmosphere, made when the planet was 70 million miles from the earth last year, suggest that Mars has a concentration of hydrogen compounds in its...
Strenuous Climate. Kaplan's discovery was made possible by French Astronomers Pierre and Janine Connes, who developed new equipment at the Observatoire de Haute-Provence that enabled them to produce the most detailed spectrograms of Mars ever made. Originally intended to reveal data about atmospheric pressure at the Martian...
The discovery of methanelike compounds on Mars, Kaplan believes, leaves only one important obstacle to life on the red planet: the apparent lack of water in liquid form. What little Martian water there is exists as polar-cap frost or vapor in the atmosphere; there are no oceans or even...
Convincing Picture. Scientists may soon be able to talk about Mars with more certainty. Astronomers Pierre and Janine Connes have now improved their instruments. They hope to make new and better spectrograms next year when Mars passes within 60 million miles of the earth. When these are available, says Kaplan...
