Only minutes after the probes hit the ground, the lander will follow, descending by parachute and braking engine. Bristling with cameras and sensors, it will study Mars' terrain and weather, snapping pictures both during its descent and on the surface. It will also carry a microphone to record for the first time the sound of the Martain wind. More important, the ship will be equipped with a robotic arm and scoop , much like the arms carried aboard the Viking landers in the 1970s. Unlike the Vikings, though, which were able to paw just a few feeble cm into the Martian topsoil, the new ship will dig out a trench nearly 90 cm deep. F o--PtY`p
How long all this otherworldly hardware will operate is uncertain. The probes, powered by batteries, should wink out within three days. The lander, with robust solar panels to keep it humming, could last three months. But even if the systems do not survive that long, their work could be profound. After all, scientists have spent years studying just the Martian skin; this will be their first chance to dig a little deeper. h+\$Z]

Passage Four }sN9QgE
An outsider approaches the subject lively, lest civic(市民的;城市的) feelings be bruised. Los Angeles gives the impression of having erased much of its history by allowing the city's development to run unchecked. Insiders like Dolores Hayden...pull no punches: "It is...common," she wrote, "for fond residents to quote Gertrude Stein's sentence about Oakland when summing up urban design in Los Angeles: "There's no there, there.'" Hayden has also acknowledged that Los Angles is generally "the first (American city) singled out as having a problem about sense of place." Both statements come from a handsome brochure-cum-itinerary, drawn up by Hayden, Gail Dubrow, and Carolyn Flynn to introduce The Power of Place, a local nonprofit group with a mission to retrieve some of the city's misplaced" there." OrqJo!FEg{
Founded by Hayden in 1982, The Power of Place lays special emphasis on redressing an imbalance in memory---and memorials. As Hayden has pointed out, in 1987 less than half the population of Los Angeles was Anglo-American; yet almost 98 percent of the city's cultural historic landmarks were devoted to the history and accomplishments of Anglo-Americans. Even these personages(名人,要人) come from a narrow spectrum of achievers---in Hayden's phrase, "a small minority of landholders, bankers, business leaders, and their architects" ----almost all of whom were male... 8 H"f9S=K
The likeliest explanation for this under-representation may be an urban variation on the great-man theory of history: History is what public figures do, and by their civic monuments shall you know them ---especially the structures they designed or built. In Hayden's view, however, "The task of choosing a past for Los Angeles is a political as well as historic and cultural one, " and the unexamined preference for architecture as the focus of historic preservation efforts can slight less conscious but perhaps equally powerful human forces. Hayden's goal has been to supplement the city's ample supply of mono-cultural landmarks and memorials with others representing its ethnic and gender-based diversity. Accordingly, some sites need new status as official land-marks, others need reinterpretation. Other sites no longer contain structures emblematic(作为标志的) of their histories or are located in blighted neighborhoods; these do not readily lend themselves to resuscitation (复兴)through renovation and commercial development , as preservationists have managed elsewhere. d?+oT0pCH
The Power of Place has identified nine places on which to concentrate in the first phase of its work: development of a walking tour of little-known Los Angeles sites, for which The Power of Place brochure serves as a guide. frO/
nx|9
The Power of Place brochure concludes its summary of what is known about each stop on the walking tour with a postscript(附言)called Placemaking, which describes the site's current status and suggests ways to make it more smelling of its past. For the vineyard/grove complex, the current situation is not unusual: "Present uses...are commercial and industrial." Then comes word of what seems to be a minor miracle: "One tall slender grapefruit free...has been preserved and relocated in the courtyard of the Japanese American Cultural and Community Center..." Suggestions for recapturing more of the past proposed by The Power of Place include returning orange trees to the Wolfskill site and installing historical markets on the Vignes site. oVZ8p-
