...victory was credited largely to Turkey's growing disdain for the eager flirtation with Russia carried on by his chief opponent, foxy former Premier Ismet Inönü, 83. In recent months, however, Demirel has begun some mild flirting of his own. He has received Rumanian Premier Ion Gheorghe Maurer and Bulgarian Foreign Minister Ivan Bashev, sent official delegations to Poland, Russia and Albania. Last week Demirel welcomed his biggest Communist visitor yet: Soviet Premier Aleksei Kosygin, the first Russian Premier ever to visit Turkey...
While the use of the interplanetary billiard technique drastically cuts travel time, Stewart says, it does little to reduce the large amounts of fuel and great initial thrust required to send a spacecraft to the distant planets. But another rapidly developing propulsion system, the solar-powered ion engine, may well solve that problem in time for the flights of the 1970s. Using electricity generated by solar panels, these engines produce a stream of ions (charged atomic particles) that provide a minute amount of thrust - usually measured in hundredths of a pound...
Accelerated by Ions. Unlike chemical rockets, which burn most of their fuel in a few minutes, ion engines can operate continuously for months and even years on an incredibly small amount of fuel. One experimental ion engine recently completed 341 days of steady operation. Thus, after a powerful chemical rocket has boosted a spacecraft beyond the earth's gravitational pull, the ion engine can take over, gradually and steadily accelerating the craft to its planned velocity over the months and years of a long space trip...
...floods that tore through the Renaissance city of Florence have gone, but the mud and shock remain. So far, 885 objects of irreplaceable art have been declared casualties. The principal victim: Cimabue's 13th century Crucifix ion, drowned inside the Santa Croce museum, where waters rose more than 14 feet. "It's a corpse, the paint is gone, and it can only be displayed as a relic," said University of Pennsylvania Art Professor Frederick Hartt...
...level visits between the two nations this year. Long-independent Red Yugoslavia, not to be left out, has sent Premier Peter Stambolic on a working holiday to Bulgaria, and has docketed him for Greece in October. The Bulgarian Foreign Minister meanwhile has gone to Turkey, which Rumanian Premier Ion Gheorghe Maurer visited last month. And last week, in the first visit to the Aegean kingdom ever made by a Communist Premier, Maurer flew to Greece...
