...system, developed by a New Jersey firm called CellularVision, has been operating in Brooklyn since July. It uses microwave signals of such high frequency that they can bounce off buildings and still be received by a window-mounted antenna no bigger than a magazine. The system, which could be available throughout New York City and in other major TV markets by mid-1994, can deliver as many channels as cable TV without the expense of having to wire up each individual home -- a prospect that could threaten the virtual monopoly that many cable companies currently enjoy...
...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...
Eight years ago he pointed an antenna up into the sky, hoping to find something, anything, to indicate that we are not alone. Since then he's been waiting. And waiting. And waiting...
