Section B How far can we go into space? (1a~1e+Reading Plus) Unit 6 Beyond Earth At the end of the class, we are able to: 1. read the text To the Stars and Beyond and understand the main idea — how far humans have gone into space and the challenges of visiting other stars. 2. match each paragraph with its main idea and complete a mind map using information from the text. 3. discuss questions about space exploration, such as ancient beliefs about stars, Voyager 1’s record, the furthest human space travel, and the future of space exploration. Learning Objectives Warming Up Moon ................ 400,000 km Mars ................ 225 million km Voyager 1 ........... 23.5 billion km Nearest star ........ 40 trillion km How far do you think humans have gone into space? Guess and answer. Which one have we reached? Reading Pre-reading 1a Where do you prefer to find information about space exploration? Choose those that are true for you. A. Popular science magazines. B. Science fiction books. C. Online news. Let’s skim! 1b Read the title and the text quickly. Where would you find an article like this? To the Stars and Beyond Identifying the text type Before your read, decide what kind of text it is. Is it a sci-fi story, popular science article, news report, or something else? A popular science magazine or a science website. Let’s scan! 1c Read again and match each paragraph with its main idea. Paragraph 1 A. Long distance space travel is difficult for humans. Paragraph 2 B. Humans have long been curious about the stars. Paragraph 3 C. In the future, it may be possible to visit another star. Paragraph 4 D. No spacecraft has travelled close to another star. While-reading Check your answer. To the Stars and Beyond Since the beginning of human history, people have looked up at the stars and wondered what they were like. Many ancient cultures believed that these points of light were from gods or other mysterious worlds. However, as technology and science developed, we learnt the truth about stars. They are real places like our own sun, and they are further away than anyone imagined. This raises the question: Can we visit the stars one day? The man-made object which has travelled furthest 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. Now, Voyager 1 is an amazing 23.5 billion kilometres from Earth, but that is still a long way from Earth’s nearest star, Proxima Centauri. That star is 4.2 light years away—about 40 trillion kilometres! The challenge of visiting the stars gets even bigger for space flights with humans. The furthest that any human has gone in space is only about 400,000 kilometres, around the other 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! 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. While this is not possible right now, with nations and scientists cooperating with one another, there is hope that the necessary technology will be developed. Humans have set foot on the moon, successfully landed rovers on Mars, and even photographed other galaxies. In time, it seems likely that one day we may reach the stars as people once dreamt. A. Long distance space travel is difficult for humans. B. Humans have long been curious about the stars. C. In the future, it may be possible to visit another star. D. No spacecraft has travelled close to another star. Para 3 Para 1 Para 4 Para 2 1d Complete the mind map with the information from the text.

Tick (✓) the uses of satellites that are mentioned. as homes for people for research to make maps to grow plants to help us communicate to collect energy from the sun to help us know the weather to know the position of things on Earth All about Satellites In October 1957, people listening to radios around the world heard something no one had ever heard before. For three weeks, there was just “Beep, beep, beep.” About one beep a second. Millions of people sat round their radios just listening for this beep. The beep itself was not all that amazing. The amazing thing was the place where it came from—space. The beep came from the world’s first man-made satellite, Sputnik 1. Sputnik 1 was launched by the Soviet Union on 4 October 1957. It was round, made of metal, and more than two times larger than a basketball. It weighed about 84 kilograms, travelled at 29,000 kilometres an hour, and took 96.2 minutes to circle Earth. Sputnik 1 stopped beeping when its radio battery died on 26 October, and it burnt up when it fell back to Earth on 4 January 1958. The launch of Sputnik 1 also began the age of satellites. The first satellites were used for research. Through them, we can better understand the world we live in. They also send back photographs that help us to make better maps of our world. Communication satellites were also soon developed. These allow TV and radio signals to be sent across oceans or to places thousands of kilometres away. This is how people can watch TV across continents and oceans. Weather satellites soon followed. These can tell us when a storm is coming or whether it will snow next week. One new kind of satellite that is now becoming more useful to the public is the positioning satellite. This satellite works with a highly complicated system, like the BDS (BeiDou Navigation Satellite System), which can tell us where our car or even our mobile phone is. It seems that there is no end to the possible uses of satellites. The only real limit to their use is our own imagination.

Why was Sputnik 1 important? About 3 months. It burnt up when it fell back to Earth. It was the world’s first man-made satellite. It began the age of satellites. All about Satellites In October 1957, people listening to radios around the world heard something no one had ever heard before. For three weeks, there was just “Beep, beep, beep.” About one beep a second. Millions of people sat round their radios just listening for this beep. The beep itself was not all that amazing. The amazing thing was the place where it came from—space. The beep came from the world’s first man-made satellite, Sputnik 1. Sputnik 1 was launched by the Soviet Union on 4 October 1957. It was round, made of metal, and more than two times larger than a basketball. It weighed about 84 kilograms, travelled at 29,000 kilometres an hour, and took 96.2 minutes to circle Earth. Sputnik 1 stopped beeping when its radio battery died on 26 October, and it burnt up when it fell back to Earth on 4 January 1958. The launch of Sputnik 1 also began the age of satellites. The first satellites were used for research. Through them, we can better understand the world we live in. They also send back photographs that help us to make better maps of our world. Communication satellites were also soon developed. These allow TV and radio signals to be sent across oceans or to places thousands of kilometres away. This is how people can watch TV across continents and oceans. Weather satellites soon followed. These can tell us when a storm is coming or whether it will snow next week. One new kind of satellite that is now becoming more useful to the public is the positioning satellite. This satellite works with a highly complicated system, like the BDS (BeiDou Navigation Satellite System), which can tell us where our car or even our mobile phone is. It seems that there is no end to the possible uses of satellites. The only real limit to their use is our own imagination. Share your answer. 2. What other types of satellites do you know?

Have you seen a photo of your city, town, or home from space? Does it change how you think of your world? How so? Yes, I have seen a photo of my city from space. It made me feel that Earth is beautiful but also small. It changed how I think because I realized we are all living on the same planet and should take care of it.
