...goes," reflects geologist Ken Hudnut somberly, "maybe we'll catch a precursor." A hot wind swoops across the desert as Hudnut retrieves a plastic box from under an oleander bush and pops the lid to reveal the small satellite receiver it shields from blowing sand. Nearby, a tripod-mounted antenna straddles a survey pipe like a spindly sentinel. Coded signals beamed down by orbiting ! satellites, Hudnut explains, serve to pinpoint the location of the pipe. The slightest shift in the pipe's position, and Hudnut will know the earth around it is on the move...
...plan -- a big "if" when it comes to new technology -- broadcast history will be made in a meeting room on Capitol Hill this week. A new kind of television signal will leave the Bethesda, Md., TV tower of WETA, a PBS affiliate, fly across downtown Washington, strike an antenna on the roof of the Capitol building and zip down a cable into the Thomas P. O'Neill Room two floors below. There, before an audience of Senators, Congressmen and assorted commissioners, magician Harry Blackstone Jr. will draw back a black cloth and reveal the first image ever to be broadcast...
While NASA studied Magellan's images, another space explorer made history last week. Moving out beyond Mars, Galileo became the first spacecraft to have a close encounter with an asteroid. But pictures of the mysterious planetary fragment, called Gaspra, are unavailable because Galileo's main antenna for sending out images is frozen in the wrong position. Not until 1992, when Galileo swings back by Earth, can smaller antennas on the craft successfully transmit the missing pictures. The frustrating delay makes scientists all the more grateful for Magellan's reliable -- and revealing -- signals from Venus...

Gorbachev apparently was listening if not watching. His security guards stayed with him at the Foros dacha, scrounged up some old radio receivers that had been forgotten but not discarded, and set up a jury-rigged antenna so they could monitor foreign radio coverage of the coup. Gorbachev later praised the reporting of the British Broadcasting Corp., Radio Liberty and Voice of America -- without seeming to recognize the irony that all three networks had been jammed by the Soviet government not so very long ago. Though he said he had been subjected to intense "psychological pressure," this apparently consisted...
