...Soviet Union's Salyut space laboratory last week that there were hints in Moscow that the manned flight might last a month or more. Inside Salyut's large cabin, the three cosmonauts were running tests to determine the physical effects of weightlessness on man, tending a small on-board vegetable patch in which cabbages and onions were growing, and comparing their observations of earth with those being made from two planes flying at much lower altitudes directly below them. Not forgetting their other obligations, the cosmonauts also took time to radio their approval of "the wise foreign...
Even as their own Mars vehicle raced toward its goal, the Soviets had another reason to be pleased. Six months after its landing, the eight-wheeled moon rover, Lunokhod I, was still continuing its lunar explorations, digging up soil samples with a conical drill and analyzing them with on-board instruments. It was also photographing the moonscape and scanning the heavens with an X-ray telescope that has already detected at least two sources of X-ray emissions in distant space. So overjoyed were the Russians by Lunokhod's performance that Pravda was moved to proletarian metaphor and compared...
...midweek, mission controllers at the Kazakhstan cosmodrome succeeded in raising the craft's orbit to 166 miles by 161 miles, apparently by firing Salyut's on-board rockets. Still, Veteran Space Watcher Heinz Kaminski of West Germany's Bochum Observatory calculated that the boost would keep Salyut alive only for another seven weeks at the most -enough time for more docking attempts but too short a life-span for setting up a working space station...
...have agreed that old-fashioned heads are no longer adequate. But they differ strongly in their assessment of two newer ways to control boat sewage: 1) "primary treatment" on board in a device known as a macerater-chlorinator, which vents the purified effluent over the side; or 2) an on-board holding tank requiring that the effluent be pumped out at a dockside station, which in turn pumps it into a local sewage-disposal system...
...maneuvers near and on the moon-if only because they had never before been attempted. As the mission reached its climactic moments and Eagle, the lunar module, was curving down to within a few miles of the moon, Eagle's computer reported: "Program alarm." Eagle's on-board computer was being asked to make too many calculations in the frenetic moments before touchdown. It had begun to balk at having to track Columbia while also making the final descent. "It gave us grave concern," said Director of Flight Operations Chris Kraft. Mission Control quickly spotted the cause...
