Enigmatic Features. As Mariner 6 approaches its goal this summer, one of its two television cameras will begin shooting a series of pictures that will show the full disk of the planet six times more clearly than it can be seen through Earth telescopes. While Mariner 6 sweeps over the equatorial regions of Mars, both cameras will shoot a series of 24 closeup pictures programmed to include areas of interest on the red planet: permanent and variable dark markings, "canals" and "oases," white markings on crater rims and other enigmatic features that have been seen through terrestrial telescopes or were...
...polar regions of the planet, shooting closeup photographs of the white polar cap and areas that appear to change color seasonally. Mariner 7 is scheduled to be launched on March 24, but will take less time than its predecessor to make the trip; its trajectory is different and the Earth will have moved some 25 million miles closer to Mars during the month that separates the shots...
...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...

...effects on the astronauts of two phenomena described by Einstein's relativity equations: 1) time actually runs slower for an object as its speed increases-the so-called "time dilation" effect, and 2) time speeds up for an object as it moves away from a body (like the earth) exerting a gravitational force...
