Has Reading B changed your opinion in any way? Discuss with a partner. The reading has given me more to think about. Stephen Hawking said that “our future should be safe” once we colonize space, which I agree with. But I would hate having to stay indoors most of the time ! CONTENTS 1 2 3 4 Before You Read Reading Comprehension Reading Skill Vocabulary Practice A mission to our planetary neighbor Mars would take at least a year—six months to get there and six months to return. This sounds like a long time. But what’s more difficult than getting to Mars is actually living there. People who want to live in this environment would need water to survive, and they would probably have to take it with them from Earth. Recently, however, scientists found signs of a large body of liquid water under the surface of the planet. If confirmed, it would make people on Mars more independent from Earth.
