...seasonal growth of vegetation. When the thin icecaps at the planet's poles disappear with the coming of the Martian spring, belts of darker color creep toward the equator, sometimes crossing it. This effect might be caused by some nonliving chemical change under the influence of drifting water vapor, but biological action is more likely...
...spaceship was thick enough to contain a good-sized oxygen tube. It may be an umbilical cord supplying oxygen from the spaceship's tanks, besides carrying wires for communication and telemetering. The tube could also carry away carbon dioxide from Leonov's breathing, water vapor from his perspiration and excess heat. The oxygen cylinders on his back may have been for emergency...
...panels are covered on both sides with thin sheets of copper and aluminum separated by plastic. The metal sheets are electrically charged, but normally no current flows between them. When a micrometeoroid penetrates the aluminum, it will punch a hole in the plastic and fill the hole with metal vapor that is a good conductor of electricity. Although the gas will dissipate quickly, there will be time for a brief pulse of electricity to cross the barrier and inform the satellite's electronic brain. Instruments in the satellite will record the time of each hit, identify the panel...
Poison for Toads. The reactor itself was completely gone, its graphite moderator and several hundred pounds of uranium fuel turned to vapor by temperatures above 8,000°F., roughly the same as the surface of the sun. For a fraction of a second before it evaporated, the reactor had generated millions of times as much energy as Hoover...
...giant balloon hoisted the Johns Hopkins telescope 16 miles high-high enough to get it up above most of the dust and water vapor in the Earth's atmosphere, high enough for a clear look at the dark-blue daytime sky where stars and planets glow with hardly diminished brilliance. Most important of all, it was high enough for the mechanized scope to scan accurately the infra red rays from the sun that were being bounced off Venus...
