This raises the question: Can we visit the stars one day? • What did some ancient cultures think about the stars? Why? They believed these points of light were from gods or other mysterious worlds. Because at that time, technology and science were underdeveloped, and they couldn't explain natural phenomena. 4. Check the answers and learn the text para by para. Can we visit the stars one day? Reaching For The Stars The man-made object which has travelled farthest from Earth is Voyager 1. This spacecraft was launched in 1977. In case Voyager 1 is found by alien life, a special record with sounds and pictures from Earth is carried on board. It shows who we are and where we are from. By 2025, Voyager 1 was over 25 billion kilometres from Earth, but that is still a long way from Earth's second-closest star, Proxima Centauri. That star is 4.2 light years away—about 40 trillion kilometres! Achievement • Voyager 1 was launched in ______. • Voyager 1 carried a special ______. 1977 record 4.

Can we visit the stars one day? Reaching For The Stars The challenge of visiting the stars gets even bigger for space flights with humans. The farthest that any human has travelled in space is only about 400,000 kilometres, to the far side of the moon. Time is a big problem. At present, even a journey to the planet Mars will take around six to nine months. What will the astronauts eat and drink during this period? And how about their health and safety? These problems grow when we talk about visiting another star. It might take hundreds of thousands of years to get there!

Do you know any details about it? It is about 400,000 kilometers to the far side of the moon. Details: It's the Apollo 11 mission that first landed humans on the moon in 1969. In China, we also have the "Chang'e" lunar exploration program to explore the moon. 4. Check the answers and learn the text para by para. Reaching For The Stars Scientists, however, believe that visiting the stars is not a completely wild dream. One idea is to have the astronauts sleep during their journey, like some animals do in winter. Another is to develop much faster spacecraft. Expectation • Astronauts can ______ during their journey. • We can ______ much faster spacecraft. Can we visit the stars one day? sleep develop • What do you think about the future of space exploration? 4. Check the answers and learn the text para by para. • What do you think about the future of space exploration? I think it is very promising. Scientists have already landed rovers on Mars and photographed galaxies. Although challenges exist, with nations and scientists cooperating with one another, it is likely that we will reach other stars one day. Humans will never stop exploring the universe.
