Mars, commonly referred to as "the red planet," is the fourth planet from the sun. Its reddish color comes from the high amounts of iron oxide on its surfaco. Mars has surface features similar to those found on the moon and on Earth. It has ranges, volcanic fields, valleys, ice caps, canyons and deserts. Mars is much smaller thàn the Earth. It has approximately half the radius of Earth. Mars orbits the Sun a little further than Earth. Mars takes 686 days to orbit Sun. In other words, the orbital period of Mars is almost twice as long as Earth's orbital period. Many spacecrafts have attempted to visit Mars, the most notable of which was NASA's Mariner 4, the first to.visit in a fly-by in 1965. In 1976, Viking 1 and 2 became the first spacecrafts to conduct successful and sustained landings on Mars. They provided the first color photographs of the "red planet."
32. The red color of the Mars comes from the sand on its surface.
33. The Earth is four times larger than Mars.
34. It takes Mars much longer to orbit the Sun than it does Earth.
35. Viking 1 and 2 were the first spacecrafts to visit Mars.
36. The first color photographs of Mars were provided by Viking landers.

There are nine planets in our solar system. These planets each have their atmosphere and environmental conditions. Scientists have been trying to research other planets to see if it is possible for life to exist on the other eight own bodies in space.
Mercury and Pluto are probably the most difficult to research because of their position in the solar system. Mercury is so close to the sun that with our current technology a space shuttle would burn up before it even reached its atmosphere. Pluto is so far away that some scientists believe that it may not even be a planot but a large asteroid or comet. A space shuttle can not trave that far away because it is so far away from the sun that it would freeze.

‘Super-Earth’ 40 light years away is best chance of finding life outside Solar System, say scientists

Point a high-powered telescope at the constellation Cetus, the sea monster, and it is just possible to make out a dim red dwarf star shining in the tail. Although it might seem unspectacular, orbiting around that star is a rocky planet that could hold the answer to whether we are alone in the universe.

Scientists say the planet is a ‘Super-Earth’ which is the best place to look for signs of life outside of the Solar System. Early indications suggest it has an atmosphere, and sits within the ‘Goldilocks Zone’ where it is neither too hot nor too cold for liquid water to exist.

And it is only 40 light years from Earth meaning that it could be possible to send a signal. The planet was found by an international team of scientists who have been studying data from European Space Observatory’s High Accuracy Radial velocity Planet Searcher (HARPS) instrument which looks for regular changes in brightness of stars, which suggests a planet is passing by in orbit.

A Mission to Mars

Have you ever had a dream of traveling to another planet in our solar system? If you have, there is an actual programme that is happening right now, and it hopes to send people to Mars in 2023. Known as the Mars One Mission, it will send a crew of four people on a one -way mission to colonize Mars. Those chosen people will have to be ready to say good-bye to the earth forever, as there will not be a return trip. For the people chosen, they will have to learn to do many different things. First of all, they will be living the rest of their lives with just a handful of other people, so they all must have personalities that allow them to get along. Second, the living quarters that they will have won’t be very spacious, so they will have to deal with that condition as well. If they feel homesick, they will only be able to communicate with people back on the earth via e-mail, video and audio sent back and forth. However, there won’t be any real-time communication. Even at the speed of light, communication between the earth and Mars takes about 20 minutes. Whether the Mars One Mission will actually happen is the big question that a lot of people are asking. There is an enormous skepticism in the science community, and Wired magazine gave the mission a miserable score of two out of ten on its probability scale. However, for those who dream of going to Mars, at least they can say there is a possibility that it could happen.

1, Who might like to go on this mission ?

A. People who get along with thers

B. People who get homesick easily

A. They will communicate with people on the earth

B. They will have to live with other people

C. They will live in quarters that don't have a lot of space inside

D. They will return to the earth

4. Which of the following is considered miserable ?

A. A crew on board of the Mars One Mission

B. A score of the programme on the probability scale

C. A personality of people taking part in the programme

D. A mission of astronauts to the ISS

5. How long will it take for a message to come back from Mars ?

Almost all our energy comes from oil, coal and natural gas. We call them fossil fuels. The earth’s
fossil fuels are running out. What would happen if there were no oil, coal and gas on earth?
Scientists are trying to find and use other alternative sources of energy. We can use energy
from the sun, the wind and the water.
Solar energy is unlimited. It supplies all the energy used to grow plants, to evaporate water for
rain, and to maintain the temperature of the planet. All are necessary for human life. If we’re able to
collect solar energy, we’ll be sure to make good use of this abundant source of power.
Another source of energy from nature is the wind. Wind power is clean and plentiful. Energy
from the wind has been used for centuries to move ships, grind grain, pump water and do other kinds
of work. In more recent time, wind power has been used to generate electricity.
Water can also provide power. For a long time, people have used water to power machines.
Some early uses of water power were to mill grain, saw wood and power machinery for the textile
industry. Today water power is mostly used to generate electricity.

LIFE OF A MAN Thomas is now in his sixties, and is one of the many homeless people who live on the streets he buys a newspaper most days. Today, with his fellow tramps, he reads about yesterday’ s student demonstration. Like many of the tramps that live under the bridge in New York, Thomas was not always so poor. A long time ago he was in the Navy, and like many who have been to sea for a long time, he has stayed slim and fit. Despite the strict organization on board ship, he loved the life, and had the opportunity to see many countries. He visited Poland and Russia; in South Africa he realized what he valued in each country was the people he met. He was always astonished and delighted by the ways in which the people he met differed from one country to another. Some day, he hopes, everyone will see the world as he does. After many happy years in Navy, he had to retire. The good things in life always come to an end. His mother and father had long since died and he’d lost touch with his other relatives. He came to New York and became an industrial designer. He was happy, although it wasn’t the same as the sea. He never wanted to get married and have children. And then there was the period of darkness. He smiles sadly. He shrugs his shoulders and looks at his hands. There are tears in the corners of his eyes. This is something that he cannot bring himself to talk about. “It all went wrong”, he whispers. He was silent for a minute; then recovered. He began to talk more loudly. “Look at me now it makes me angry. And what about the President? He’s been in power for years, and look what he’s done for us. Nothing! I’m still out on the streets and live the life of a tramp.” 39. It would appear that Thomas _________ A. has organized a protest recently. B. takes an interest in important events.
