But things are changing. High costs, unusual educational needs and long start-up times are no longer an obstacle(障碍) to space exploration. The scientists have developed a new type of tiny, inexpensive earth-orbiting(轨道) satellite.
So far, college students have built and launched(发射) several cube-shaped satellites, or CubeSats. At least 15 more are ready to go. Those already in orbit take pictures, collect information and send it back to the earth, just as regular satellites do.
But you might not even have to wait until you get to college to start designing and building your own satellite. A new program called KatySat aims to get teenagers to take part in. When kids understand what satellites can do, the kinds of ideas they’ll come up with may be countless.
Education isn’t the only aim of CubeSats because these tiny, technology-filled boxes are inexpensive to build and can be put together quickly, they’re perfect for testing new technologies that might one day be used on major space tasks.
The biggest challenge now is to find ways to bring the satellites back to the earth after a year or two. Or space junk could gradually increase because CubeSats become more popular.
Nowadays, college and high school students are getting a chance to learn what it takes to explore in space. Someday—perhaps a lot sooner that you imaging—you might get to design, build and launch your own satellite. If you do, you’re sure to have fun. And you might also get crazy about science for life.

As we know, it is not easy to build a satellite. Building a traditional satellite normally takes years. The
costs can be as high as $ 250 million or more. Most members of the design teams have worked in the field
for a long time. They hold advanced degrees in math, science, or engineering.
But things are changing. High costs, unusual educational requirements and long start-up times are no
longer an obstacle to space exploration. The scientists at Stanford University have developed a new type of
tiny, inexpensive earth-orbiting satellites that go from ideas to launch (发射) in a year.
So far, college students have built and launched several cube-shaped satellites, or Cube Sats. At least 15
more are ready to go. Those already in orbit (轨道) take pictures, collect information. and send it back to the
earth, just as regular satellites do.
But you might not even have to wait until you get to college to start designing and building your own
satellite. A new program called Katy Sat aims to get teenagers to take part. Once kids understand and what
satellites can do, says Ben Yuan, an engineer at Lockheed Martin in Menlo Park, Calif, the kinds of applications
they'll come up with may be countless.
"We'd like to put this technology (技术) in your hands," he tells kids." We're going to teach you how to
operate a satellite. Then we want to turn it over to you as a sandbox for you to play in. We want you to take
the technology into new directions that we haven't though of yet."
Education isn't the only goal of Cube Sats. Because these tiny, technology-filled boxes are relatively
inexpensive to build and can be put together quickly, they're perfect for testing new technologies that might
one day be used on major space tasks.
The biggest challenge now is to find ways to bring the satellites back to the earth after a year or two.
Otherwise, major highways of space junk could gradually increase as CubeSats become more common.
Nowadays, college and high school students are getting a chance to learn what it takes to explore in space.
Someday-perhaps a lot sooner than you imagine-you might get to design, build and launch your own satellite.
If you do, you're sure to have fun. And you might also get crazy a-bout science for life.
B. are low-cost and small-sized
C. are very hard to operate
D. collect more information in orbit
B. An imagination that kids usually have.
C. Something dangerous to terrify people.
D. Something difficult that stands in the way.
B. A few kids will send applications for the project.
C. Scientists designed CubeSats for kids to play with
D. Students can't design satellites without college education.
B. To show that kids lead the space research into a new direction.
C. To tell us that satellite technology can also be learned by kids.
D. To tell us that kids must study hard to learn satellite technology.
As teenagers, you have many dreams. These dreams can be very big, such as winning the Nobel Prize, or they can be small. You may just want to become one of the ten best students in your class.
Once you find a dream, what do you do with it? Do you ever try to make your dream real?
Follow Your Heart by Australian writer Andrews tells us that making our dream real is life’s bigger challenge. You may think you’re not good at some school subjects, or that it is impossible for you to become a writer. These kinds of thoughts stop you from getting your dreams, the book says.
In fact, everyone can make his dream come true. The first thing you must do is to remember what your dream is. Don’t let it leave your heart. Keep telling yourself what you want. Do this step by step and your dream will come true faster because a big dream is, in fact, many small dreams.
You must also never give up your dream.
There will be difficulties on the road to your dreams. But the biggest difficulty comes from yourself. You need to decide what is the most important. Studying instead of watching TV will lead to better exam results, While saving five yuan instead of buying an ice cream means you can buy a new book.
As you get closer to your dream, it may change a little. This is good as you have the chance to learn more skills and find new interests.
