...astronauts will not make any public statements until after their release on Aug. 12, NASA announced that, at Armstrong's request, it is amending the record of his first words on the moon. Armstrong explained that the article "a" had apparently been lost in transmission back to earth. Thus his statement should read: "That's one small step for a man, one giant leap for mankind." The change reflected the humility of the first mortal to reach the moon...
Last week, on the 157th day of an arcing, 242-million-mile journey across the solar system Mariner 6 reached its destination. In the closest approach to Mars ever achieved by a man-made object, the U.S. spacecraft flew within 2,130 miles of earth's planetary neighbor...
...endless stream of data from the red planet-information about the density and composition of its atmosphere and its varying surface temperatures. On board the ungainly, 850-lb. ship, whose four solar panels gave it the look of a stubby windmill, tiny transmitters also sent back to earth, some 60 million miles away, the best close-up portrait man has ever had of Mars. At week's end, an identical twin named Mariner 7 moved into position for similar electronic observations. Mariner 6 aimed its close-up cameras on Martian equatorial regions, Mariner 7 at the planet...
...operate efficiently, refused to chill at all. Mariner 7 caused even greater concern at Mission Control when it went off the air entirely for seven hours. Apparently struck by a tiny meteoroid, the spacecraft lost its fix on the star Canopus and its directional antenna spun away from earth. A new roll-and-search command went up from Pasadena. Mariner 7 obeyed, and though performing at less than capacity, its radio functioned again...
Both probes worked at incredibly high speeds. Once the Martian image was captured by their video equipment, it was rapidly translated into electronic signals of varying intensity representing 64 shades of light and dark. Those impulses, in turn, were beamed to earth in the binary language of the computer. To make one complete picture, the spacecrafts' equipment had to scan 665,208 points of light and dark, each of which was converted into six bits of computer information. That five-minute job involved more than 4,000,000 bits for each picture. The poky equipment on Mariner 4 needed...
