    In order to get information about distant planets, scientists invented spacecraft to travel into the solar system to see the planets up close. These spacecraft do not carry people, and they never return to Earth. However, while they are in space, they can take photographs of planets that are too far away for us to study from Earth. One famous spacecraft that has done this is part of the Voyager Project. This spacecraft is called Voyager I.
    NASA started the Voyager Project in the 1970s. During the 1960s and the 1970s, NASA sent many spacecraft into space to collect scientific information about the solar system, but none of those spacecraft carried astronauts. Two of the spacecraft that NASA built in the 1970s were called Voyager I and Voyager II. The original jobs of Voyager I and II were to get information about Jupiter and Saturn. The two spacecraft both left the Earth in 1977.
    Voyager I reached Jupiter in 1979 and began to take photographs. The spacecraft was able to get very close to Jupiter. By getting close to Jupiter, it could take very clear photographs of Jupiter’s rings and planets. Voyager I also took good photographs of Jupiter’s " Great Red Spot. " This spot is a large place on Jupiter where there is a strong storm. The Great Red Spot is so large that it could hold three planets the size of Earth inside of it! After taking pictures of Jupiter, Voyager I went to Saturn. It reached Saturn in 1980 and collected important information about Saturn’s rings.
    After Voyager I finished its work on Saturn, the spacecraft still worked well. So, NASA sent Voyager I on a new job. This time it was sent out of the solar system. NASA wanted to see how far it could go.
    Voyager I is still working today. It is now NASA’s oldest working spacecraft. It has travelled more than 9. 3 billion miles, making it the spacecraft that has travelled furthest from Earth. Actually, the spacecraft has now travelled much further than expected. As it travels, it continues to send new information back to Earth. It is expected that Voyager I will no longer work by the year 2020. At that time it will not have enough power to keep working. Still, we can certainly say that this spacecraft has done a great service in helping us to learn more about space.
Questions 56—60
Decide whether the following statements are true(T)or false(F)according to the passage.
Voyager I and Voyager II are only a part of NASA’s Voyager Project started in the 1970s.

选项 A、TRUE
B、FALSE

答案A

解析 由原文第二段中的“Two of the spacecraft that NASA built in the 1970s were called Voyager I and Voyager II”可知,旅行者一号和旅行者二号是美国航空航天局在七十年代发射的宇宙飞船之中的两艘。题干描述与文章意思一致,因此正确。
