Virgin Galactic chuẩn bị tiết lộ Máy bay tên lửa du lịch vũ trụ mới

Virgin Galactic sẽ tung ra một phiên bản mới của tên lửa du lịch không gian SpaceShipTwo của nó vào Thứ Sáu khi nó chuẩn bị để trở về thử nghiệm chuyến bay lần đầu tiên kể từ khi một vụ tai nạn năm 2014. 

SpaceShipTwo được thiết kế để bay bởi một trong hai phi hành đoàn và đưa sáu hành khách đến rìa không gian. Ở độ cao trên 62 dặm, hành khách sẽ trải nghiệm một vài phút không trọng lượng và xem trái đất bên dưới.

Sau nhiều năm phát triển, Virgin Galactic dường như đang đến gần mục tiêu làm cho dân thường thành phi hành gia. SpaceShipTwo đầu tiên đã vỡ ra thành từng mảnh vào ngày 31 tháng mười năm 2014. 

Cuộc điều tra cho thấy phi công phụ Michael Alsbury đã mở khoá cái gọi là hệ thống phủ đầy lông nhằm mục đích làm chậm lại và ổn định con tàu khi nó vào lại khí quyển. Alsbury đã bị chết, nhưng phi công Peter Siebold, mặc dù bị thương nặng, đã nhảy dù an toàn.

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.

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?

3. What does the force of gravity try to do?

4. What is thrust?

5. What does an airplane use to help it fly?

          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.

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
