【题目】For thousands of years comets have been a mystery to man. They travel across the sky very fast and have a bright “tail” of burning gas. The comet Tempel 1 has an orbit far outside the orbit of the furthest planet in our solar system, Pluto. It has been there for 4.6 billion years, 133 million kilometers from Earth.Once a little American spacecraft crashed into Tempel 1. The spacecraft had a camera and it took a photograph of the comet every minute before it finally crashed into its surface.

The space mission to Tempel 1 cost $335 million and was called Deep Impact. The spacecraft was traveling at 37,000 kilometers per hour when it hit the comet and the crash completely destroyed the spacecraft. But before it hit the comet, the spacecraft took some amazing photographs. The last one was a closeup picture which the spacecraft took just 3 seconds before it crashed into the comet.

“Right now we have lost one spacecraft,” said a delighted NASA engineer. Deep Impact was like an American Independence Day fireworks display. It took many years to plan and ended in an enormous explosion.

The spacecraft which crashed into the comet was made of copper and was the size of a washing machine. It was dropped from a mothership into the path of the comet and the mothership then photographed the cloud of ice, dust and organic chemicals that rose from the surface of the comet after the crash.

The crash completely destroyed the spacecraft but nothing really happened to the comet: experts believe that the crash slowed the comet down by no more than 1/10,000 of a millimeter a second. The aim of the mission was to study for the first time the interior of a comet.

The mothership was 480 km from the explosion and observed the crash and the explosion with instruments for 800 seconds. Seven satellites, including the Hubble space telescope, watched the moment of drama, and over the next day and night about 50 telescopes on Earth were watching the distant comet.

1How many hours did it take for the spacecraft from the earth to touch the comet Tempel 1?

A. About 2,500. B. About 3,500.

C. About 4,500. D. About 5,500.

2Which of the following shows the possible orbits and positions of the comet Tempel 1?

S=Solar     P=Pluto
