The astronauts working in these towns wear their space suit and also do everything they would really have to carry out if they ever go to Mars in the future.
But Mars would be like Earth, a temporary（臨時(shí)的） place for humans. When the Sun starts swallowing up(吞掉) the planets, Mars will disappear only hours after Earth. So Mars only seems to be the ideal place to spread the human beings. It is also a good location to send humans if ever there is a disaster on Earth. By saying disaster, I mean asteroids(小行星) hitting and things like that.
If we humans do not want to disappear when Earth or Mars gets swallowed up, we will have to go and live beyond the solar system. But are there any planets outside our solar system prepared to support life? Astronomers’ answer is:
“If Earth can support life, why can’t other planets do the same too? Astronomers have already discovered a Jupiter(木星)- like planet orbiting a Sun-like star, so why not an Earth-like planet orbiting a Sun-like star?
To achieve this goal though, many other problems have to be taken into consideration. How do we transform(改造) a dusty planet like Mars into one more or less like our Earth? How should we go on? There is still a long way to go.

Eating in space is different from eating on Earth. The food that astronauts carry with them does not look like the food you eat.

Some food is carried in closed bags. It is cooked and frozen before the astronauts get it. All the water is removed from the food. In the spaceship, the astronaut puts the water back. He "shoots" hot or cold water into the food bag with a special （特別的） gun. He eats the food through a small hole in the bag.

Other foods come in bite （一口） sizes. The astronaut puts a whole piece in his mouth at once. There can be no crumbs（碎屑）. Crumbs would float around the spaceship and get in the way. Meat and cake often come in bite-size pieces.

Astronauts cannot drink water from open cups. The water would float in drops into the air. The water is put in the special gun. The astronaut shoots the water into his mouth.

Eating in space is not easy. Astron-auts must learn to eat this way.

10. Some space foods are carried in _______ .

A. water guns B. lunch boxes C. closed bags D. crumbs

11. Why can't astronauts drink water from open cups?
