 Holiday on the Moon?
A People first visited the moon in 1969, when Neil Armstrong made ‘a giant leap for mankind’. 
 Between 1969 and 1972, a total of 12 men walked on the moon. After the moon landings, the 
 focus of space travel turned to making reusable spacecraft and building the International Space 
 Station.
B Construction has not yet begun, but some experts predict that there will be a hotel on the moon 
 in the next 50 years. Virgin Galactic is already planning tourist flights to orbit the Earth, and may 
 be able to touch down on the moon to deliver tourists one day.
C The big challenge is cost. Lots of people want to visit space, but at the moment, a ticket for even 
 a short journey is more than most normal people can afford. The other challenge is training and 
 fitness. Astronauts require at least six months of training to be prepared for the physical effects 
 of rocket travel. Most people don’t have the time to prepare.

V. Read the text, and do the following tasks.
 Out of This World
A 1 _______________ is an object that orbits another object in space. There are natural satellites like 
the moon, which orbits the 2 _______________, and there are also artificial satellites. Artificial satellites 
are man-made objects which are sent into space. In 1957, the Soviet Union launched the first artificial 
satellite, Sputnik 1, and there are about three thousand artificial satellites in orbit around the Earth. 
We use them to transmit phone calls and TV signals across the world, to navigate journeys, to forecast 
the weather, and to study the universe.
The largest artificial satellite in orbit is the International 3 _______________ or ISS. The American 
4 _______________ started taking material into space to build the ISS there in the late 1990s, and 
different teams of researchers have lived there continuously since November 2000. The ISS was also 
the destination of the world’s first space tourists. One of them, the Hungarian- American billionaire 
Charles Simonyi, enjoyed the visit so much that he paid $35 million for a second trip. During his visits 
to space, he helped with research projects and chatted to schoolchildren in the USA via a video link.
Space tourism will be more popular in the future, thanks to the development of sub-orbital spacecraft. 
Travelling to altitudes of over one hundred kilometres, these craft reach the boundaries of space, at 
the edge of the Earth’s atmosphere. From there, passengers get a breathtaking view of the Earth, and 
can also experience 5 _______________. Prices started at $200,000 for a three-hour trip, but flights will 
certainly become cheaper in the future. Scientists hope that the increase in space tourism will help to 
raise money to fund further space projects.

 A New Home
The president of the planet Trojan was standing in front of her palace. She spoke to all the people. 
“People of Trojan!” she said. “I have some bad news. Another planet is coming towards us. One hundred 
years from now, the other planet is going to hit us and destroy us. There is nothing we can do.”
The Trojan people were very frightened. The president said more.
“Don’t worry. We have a plan. We’re going to build spaceships - the biggest spaceships in the history of 
universe. Each spaceship is going to carry 10,000 people - and we are going to build 20,000 spaceships! 
In this way, we can take every Trojan man, woman, and child to a safe place - before the other planet 
hits us.”
The people asked, “Where? Where is this safe place?”
The president said, “There is another planet, very far from here. It is a planet where Trojan people can 
live. The air is like our air; the water is like our water; and there is room for us. The name of this planet 
is: Earth!”
The next day, the people of Trojan started to build the spaceships. It took them a very long time - more 
than fifteen years - to build the first 1,000 spaceships. And after fifty years, 5,000 spaceships were 
ready. And finally, all the 20,000 spaceships were ready. The spaceships were round, like huge yellow
