Question

Reading Task. Read the text and fill in the sentences with the information from the text. Write NOMORE THAN THREE WORDS OR A NUMBER. Space Exploration - Voyagers 1 and 2 The Voyager 1 and 2 spacecrafts left Earth in 1977 on a five-year mission. Their mission was to reach Jupiter and Saturn and send information back to earth about them. Jupiter and Saturn are the hugest planets in the solar system. In 1981, they finished their mission. But, theykept going. Scientists decided to plan a longer trip for them: they would travel even further until they reached Uranus and Neptune. Voyagers 1 and 2 are very smart. They were built with no moving naris. They use the breakdown, or the decay, of the space element "plutonium" to create fuel. They can each get the equivalent of 30,000 miles per gallon of gasoline! They were made to be able to work in radioactive environments. The "gas giants" - Jupiter, Saturn, Uranus, and Neptune - are very radioactive places. So far, Voyagers 1 and 2 have sent information back to Earth from farther away than any other spacecraft. Scientists have learned about the atmospheres, interiors, and rings of the gas giant stars. They have also learned about the moon of these stars. Scientists think that they will keep getting information from Voyagers 1 and 2 until about 2020. At that time, the power on the Voyagers 1 and 2 will not be strong enough to send information back to Earth. 1. The Voyagers started their mission in 2. Scientists plan that the Voyagers would go to 3. The Voyagers use the element_ 4. The are highly radioactive areas. [6] to create fuel. 5. Information from the Voyagers could reach Earth to any other spacecraft. 6. It is believed that information from the Voyagers will come before _compared = 33333.​
