Indeed, after only a week on the surface of Mars, Pathfinder had conducted dozens of worthy science experiments, had begun to challenge at least one long-held perception about the red planet and had transmitted more than 1,700 photos of the landscape, many of which were incorporated into a "monster pan," a spectacular 360[degrees], three-dimensional, horizon-to-horizon mosaic image that, when viewed through 3-D glasses, is almost as good as being there. The mission had also achieved a historic first on Mars: a motor-vehicle accident...
...dirt with helium nuclei and analyzing the resulting patterns of radiation, the spectrometer revealed that the soil was rich in iron and virtually identical to that examined at other sites 21 years earlier by the Viking landers. This suggested to scientists that Martian topsoil is widely distributed by the planet's frequent global dust storms. Why the reddish hue? "The surface of Mars is rusting," explains Jim Bell, a Cornell University scientist...
...explosive volcanism. Andesites are typically formed by the repeated melting, solidifying and remelting that occurs during the tectonic-plate processes that shape and reshape terrestrial continents. Yet Mars seems to have very few volcanoes and shows no signs of tectonic plates, which suggested to some scientists that the planet wasn't internally active long enough to form andesites. Then what process could have created Barnacle Bill...
Naming features on the red planet is hardly an exact science. After putting in 16-hour days, says Bob Reid of the Mars Pathfinder science team, "we choose names that keep us happy." Match each Martian formation below with its terrestrial namesake...
Your poll showed that 13% of Americans believe intelligent beings from other planets have been in contact with members of the U.S. government. I think the numbers would have been higher if you had asked people if they thought U.S. government officials were from another planet. Why would E.T.s want to speak to anyone in our government?
