SPACE COLONISATION: Future or Fantasy? Since Neil Armstrong set foot on the moon on 20th July, 1969 and declare smail step for man, one giant leap for mankind", people have been dreaming abou creating futuristic communities in space. Science fiction films such as 2001: A Sp Odyssey and Star Wars have filled our minds with images of spacecraft travelling at the speed of light to colonies on other planets in another solar system. Until now these ideas have just been fantasy, but now leading scientists such as Stephen Hawking say that colonising space is the only answer for the future survival ol mankind; otherwise we will die out. 1__But is space colonisation really possible? One solution would be for us to move to space stations orbiting near Earth. After all. astronauts have already been living on NASA's International Space Station (ISS continuously since 2000. The IS gets its power from solar panels, it generates its own oxygen and even recycles water, but there's still a huge problem; all of its food and other supplies have to be sent from Earth. 2__So maybe colonising the moon would be a better solution! The moon has rich resources which could be used to construct a colony. Also, in 2009, scientists found water on the moon, which could be used to extract oxygen for breathing. 3__There is no atmosphere on the moon and it is boiling hot during 13 days of sunlight and then freezing cold during 13 days of darkness. So any human colony there would have to live in a huge indoor biosphere". Mars would be another option, but the problems there would be similar to those on the moon. Scientists have suggested creating a more Earth-like atmosphere there by releasing carbon dioxide and warming it up, but this could take about 1,000 years! Stephen Hawking believes that the best solution is to look for Earth-like planets to colonise. "If only 1% of the 1,000 or so stars within 30 light years of Earth had an Earth-sized rocky planet in just the right place for life, there would still be 10 planets for colonisation in our 'neighbourhood," Hawking said. 4___ Travelling on Voyager 1, the fastest spacecraft we've ever sent into space, it would take over 700,000 years to get to Alpha Centauri, the closest star system. Hawking, though, believes that new technologies could soon help us to travel just below the speed of light. 5 If we had endless amounts of money for space exploration, we would have already overcome these problems and built the first space colonies. The fact is, it costs about £6,000 to put half a kilo of anything into near-Earth orbit. 6 Just imagine – if people hadn't given Columbus money for his voyage to America in 1492, NASA probably wouldn't even exist today! So, although there are many challenges to overcome, Professor Hawking stll believes it will only be a matter of time before we are living in space. 7 do you think? Is space truly the final frontier? *an environment that supports life​

Диалог «Путешествие на корабле» - «Travelling by ship»

- Have you ever travelled by ship, Mark?

- No, I haven’t. I suffer from seasickness. And you?

- Yes, I have. I travelled with my parents by a modern ocean liner last summer. It was a long sea voyage in the waters of the Indian Ocean.

- Did you like the journey?

- Oh, it was fantastic! We had everything we wanted: comfortable rooms, delicious food, lovely music and much entertainment. I think all passengers were relaxed and happy. And we met a lot of nice people there.

- And did you face any dangers at sea like unexpected icebergs or violent storms?

- We were lucky. The ocean was mainly calm. Don’t worry, Mark. I think that travelling by ship is not so dangerous today.

- Oh, I woudn’t say that. The famous ship “Titanic” was considered safe and unsinkable, you know. But the tragedy happened. Besides, it’s hard to believe but there still exist modern pirates who attack private yachts and even cruise ships.
