NASA is moving ahead with plans to put a long-armed lander on Mars’ icy north pole to search for clues① for water and possible signs of life.

The $386 million Phoenix Mars is planned to touch down in the Martian arctic in 2008. The stationary probe will use its robotic arm to dig into the icy land and pick up soil samples② to analyze. In 2002, the Mars Odyssey orbiter spotted evidence of ice-rich soil near the arctic surface.

Scientists hope the Phoenix mission will find clues to the geologic history of water on the Red Planet and determine whether microbes③ existed in the ice.

Phoenix will be the first mission of the Mars Scout program, a renewed, low-cost effort to study the Red Planet. “The Phoenix mission explores new territory in the northern plains of Mars analogous to the permafrost regions on Earth,” Peter Smith said.

True to its name, Phoenix rose from the ashes of previous④ missions. The lander for Phoenix was built to fly as part of the 2001 Mars Surveyor program. But the program broke down after the well-known disappearance of the Mars Polar Lander in 1999. The Polar Lander lost contact during a landing attempt near the planet’s south pole after its rocket engine shut off prematurely, causing the spacecraft to fall about 130 feet to almost certain destruction.

The Phoenix probe had been in storage at a Lockheed Martin clean room in Denver before it was reused for its present mission. It will carry science instruments that were designed for the Mars Surveyor program including an improved panoramic camera and a trench-digging robotic arm. Phoenix will lift off from the Kennedy Space Center in August 2007 and land on the planet nine months later.

No country in the world has more daily newspapers than the USA. There are almost 2000 of them,as compared with 180 in Japan,164 in Argentina and 111 in Britain. The quality(质量) of some American papers is quite high and their views are used all over the world. Excellent newspapers like the Washington Post or the New York Times have a powerful influence(影响) all over the country. However,the Post and the New York Times are not national newspapers in the sense that The Times is in Britain of Le Monde is in France,since each American city has its own daily newspaper. The best of these give detailed(详细的)accounts of national and international news,but many tend to limit themselves to state or city news.?

Like the press(报刊) in most other countries,American newspapers report news from the “exciting” and “relaxing” to the serious. They try to entertain people as well as give information,for they have to compete with the attraction of television.

Just as American newspapers try to satisfy all tastes,they also try to attract readers of all political parties. A few news papers support extremist(极端主义者) groups on the far right and on the far left,but most daily newspapers try their best to attract middle-of-the-road Americans who are mainly moderate(温和的).Many of these papers print materials by well?known journalists of different political and social views,in order to give a balanced picture.?

As in other countries American newspapers can be either responsible(负责任的) or irresponsible,but it is generally accepted that the American press serves its country well and that it has more than once exposed political scandals(丑闻),for example,the Watergate Affair(水门事件).?
