How does a rocket get to outer space?

A rocket uses fuel to make power for the engine. The fuel is set on fire inside the rocket. As the fuel burns, it creates gases that have great pressure. These gases are blasted out of the rocket engines.These gases all go out the bottom of the rocket engine where it is open. They come out so fast and with so much power that the rocket is pushed up. It is pushed up so hard that the rocket overcomes the force of gravity, which tries to keep everything on the ground. The force that pushes up against the front of the rocket is called thrust. Unlike an airplane, a rocket does not use wings to help it fly. It just uses the power and force created by the burning fuel to make enough thrust.

1. Where is the fuel set on fire?

2. How do the gases come out to make the rocket be pushed up?

future home is an exhibition of where we will live in the future and what our homes will be like, and it is coming to the museum of mankind on this september. the organizers say there are going to be hundreds of interesting house models and there will to be plenty of fantastic things for all age groups. One of the most exciting things to see will be the model of the space hotel, designed by the Shimuzu Corporation of Japan. As soon as space travel become cheaper, the hotel will be built about 90 km above Earth. The hotel itself will have their own air supply and food will be flown up to there from Earth on space shuttles. There will be a total of 64 guest rooms. At last, tourism themselves will be able to enjoy looking down on Earth from space

The launch of Sputnik I and Yuri Gagarin, the first human being in space, marked the beginning of space exploration and the beginning of a new and unfamiliar type of pollution.

          Satellites, solar panels, rocket bodies and fragments from space shuttles that are floating in space and are no longer functional are considered space debris. This pollution of man-made objects in space affects us here on Earth as well and will continue to affect us in future travel. In 1978, the Soviet Union Kosmos 954, which contained a nuclear power source, reentered over Canada and left debris over an area the size of Austria. In 1969, five Japanese sailors were injured by pieces of space debris that hit their ship. The largest piece, weighing one thousand pounds, landed in Australia in 1979.

          Many solutions are being considered by scientists and engineers. However, the challenge to finding a solution lies within all of the nations which take part in the space exploration.

Read the following passage and choose the best answer for each question.

Where will you go on your next vacation? Disneyland? Sea World? Outer space?

That’s right; tourists are now paying big bucks to travel into space with astronauts! The first space tourist was Dennis Tito, an American businessman. In 2001, he paid about $20 million to ride on a Russian rocket to the International Space Station. The Space Station circles 220 miles above Earth. Tito stayed on the station for a week, hanging out with astronauts and eating space food. The latest space tourist was Anousheh Ansari, an Iranian-born woman from the United States who went to the Space Station in mid-September 2006.

How safe is space travel? Apart from the risk of crashing, space tourists have some special things to worry about. Earth’s atmosphere protects us from dangerous radiation from the sun. Space travelers are exposed to more of the sun’s rays. But for tourists spending only a few days or weeks in space, the radiation probably isn’t harmful.

A bigger problem might be space sickness. Without Earth’s gravity to hold them down, visitors to the Space Station float around inside the craft. It may look like fun on TV, but it can make first-time space travelers dizzy and sick. Luckily, the sickness usually wears off quickly. Then space tourists can enjoy their trip and the amazing view of Earth.

 While in outer space it is likely that people will _____.

A. Experience space sickness

B. Not need space suits

C. Will get a sunburn

D. Make side trips to Mars
