...early astronomers, it seemed obvious that there was water on Mars. What else could form the white polar caps that shrank so noticeably every spring and began to grow again in the fall? And what could possibly produce the springtime darkening of the Martian surface other than rapid vegetation growth stimulated by water released from the melting caps...
...atmosphere of Mars. Some have suggested that the color changes are due to unknown chemical reactions, or to seasonal winds that alternately deposit sand from bright lowlands onto the dark highland surfaces and then blow it away. Their views have not been contradicted by spectrographic studies of the Martian atmosphere. Although some of these studies have detected traces of water vapor, the evidence has not been distinct enough to be completely convincing to many scientists. Now all doubts have apparently been erased. A team of astronomers working at the McDonald Observatory in Texas announced last week that they had obtained...
Better Focus. To obtain their proof, Stephen Little of the University of Texas and Astronomer Ronald Schorn of the Jet Propulsion Laboratory turned to the same kind of tools that they and other scientists had previously used in attempts to detect Martian water: the telescope and the spectrograph, which breaks light into its rainbow (spectrum) of colors and records it on a photographic plate. With the aid of a $100,000 NASA grant, mirrors had just been refinished on the 82-in. McDonald telescope, bettering its focusing by a factor of three. The optics of the spectrograph had also been...
...student knows. But neither is there any point to it, unless the benefits outweigh the costs. And to give proper scientific credits: mind-boggling rearrangements of the solar system have been discussed before; e.g., by Fritz Zwicky at Caltech and Freeman Dyson at Princeton. Regardless, the examination of the Martian moonlets in situ should become a scientific objective of the highest priority; it could be the key to understanding the origin of the solar system and especially of the inner planets...
...soft landings on the surface of the planet. In a search for any obvious evidence of life, TV cameras aboard the landers will take pictures of the immediate surroundings. Delicate instruments will sniff and analyze the atmosphere at ground level. Mechanical devices will gulp up, digest and chemically analyze Martian soil for clues to life. In their findings, relayed back to Earth by radio, man may find the exciting evidence that life exists elsewhere in the universe...
