They travel across the sky very fast and have a bright ? tail? of burning gas. The et Tempel 1 has an orbit far outside the orbit of the furthest pla in our solar system, Pluto. It has been there for billion years, 133 million kilometers from Earth. Last week a little American spacecraft crashed into Tempel 1. The spacecraft had a camera and it took a photograph of the et 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 travelling at 37,000 kilometers per hour when it hit the et and the crash pletely destroyed the spacecraft. But before it hit the et, the spacecraft took some amazing photographs. The last one was a close﹣ up picture which the spacecraft took just 3 seconds before it crashed into the et. ? 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 et was made of copper and was the size of a washing machine. It was dropped from a mothership into the path of the et and the mothership then photographed the cloud of ice, dust and anic chemicals that rose from the surface of the et after the crash. The crash pletely destroyed the spacecraft but nothing really happened to the et: experts believe that the crash slowed the et down by no more than 1/10,000 of a millimeter a aim of the mission was to study for the first time the interior of a et. 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 et. 28. How many hours did it take for the spacecraft from the Earth to touch the et Tempel 1? 2,500. 3,500. 4,500. 5,500. 解析： B 數(shù)字計算題。 133 000 000247。 29.

In the past years, Chinese people have made hard and determined efforts to realize the dream their ancestors had for thousands of years. After China’ s first satellite into the Earth’ s orbit in 1970 came four flights of unmanned Shenzhou missions from 1999 to 2021. The country carried out its first one﹣ piloted space flight in October, 2021, making China the third country in the world to have independent human spaceflight ability after the Soviet Union and the United States. Then came another breakthrough on October 12, 2021, when Shenzhou 6, China’ s second human spaceflight, was launched, with a crew of two astronauts. What’ s more, the landmark(里程碑 ) spacewalk done by Zhai Zhigang, one of the three boarding Shenzhou 7, launched on September 25, 2021, leads the country further in its space exploration. Meanwhile, China’ s moon exploration project, started in 2021, has also been progressing satisfactorily. Fifty years after the Soviet Union launched Sputnik, the world’ s first man﹣ made satellite, China’ s first circumlunar(繞月的 ) satellite Chang’ e 1 took off on October 24, 2021, which became another milestone in China’ s space achievements after the above﹣ mentioned manned flights. Chang’ e 1 was expected to fulfill four scientific goals, one of which was to probe(探測 ) mineral elements on the Moon, especially those not existent on the Earth. It’ s said that the lunar
