北京中考英語閱讀練習題原文
As we know, it is not easy to build a satellite. Building a traditional satellite normally takesyears. The costs can he as high as $250 million or more. Most members of the design teamshave worked in the field for a long time. They hold advanced degrees in math, science, orengineering.
But things are changing. High costs, unusual educational requirements and long start-up timesare no longer an obstacle to space exploration. The scientists at Stanford University havedeveloped a new type of tiny, inexpensive earth-orbiting satellites that go from ideas tolaunch***發射***in a year.
So far, college students have built and launched several cabe-shaped satellites, or CubeSats. Atleast 15 more are ready to go. Those already in orbit***軌道***take pictures, collect information andsend 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 buildingyour own satellite. A new program called KatySat aims to get teenagers to take part. Once kidsunderstand what satellites can do, says Ben Yuan, an engineer at Lockheed Martin in MenloPark, Calif., the kinds of applications they’ll come up with may be countless.
“We’d like to put this technology***技術***in your hands, ” he tells kids. “We’re going to teach youhow 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 thought of yet.”
Education isn’t the only goal of CubeSats. Because these tiny, technology-filled boxes arerelatively inexpensive to build and can be put together quickly, they’re perfect for testing newtechnologies 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 yearor two. Otherwise, major highways of space junk could gradually increase as CubeSats becomemore common.
Nowadays, college and high school students are getting a chance to learn what it takes toexplore 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 getcrazy about science for life.
