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.
It is probably so expensive to travel to space because_____.
A. Astronauts want to make a lot of money
B. Astronaut food is very expensive
C. Space equipment and fuel is expensive
D. There are high taxes on space travel
Part II. Read the passage and answer the following questions. (1 pt)
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?
-> The fuel is set on fire inside the rocket.
2. How do the gases come out to push up the rocket?
-> The gases come out so fast and with so much power that the rocket is pushed up.
3. What is the force that pushes up against the front of the rocket called?
-> The force that pushes up against the front of the rocket is called thrust.
4. What does a rocket use to help it fly?
-> It just uses the power and force created by the burning fuel to make enough thrust to help it fly.
