As we know, it is not easy to build a satellite. Building a traditional normally takes years. The costs can be as high as $250 million or more. Most members of the design reams 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 student have built and launched several cube-shaped satellites, or CubeSats. 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 KatySat aims to get teenagers to take part. Once kids understand 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 thought of yet.”

Education isn’t the only goal of CubeSats. 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.

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 about science for life.
