摘要

When Pete Rossoni was a kid he loved to throw Frisbees. Most kids do―it's pure fun. But in Pete's case it was serious business. He didn't know it, but he was practicing for his future career... in space exploration. Grown-up Pete Rossoni is now an engineer at NASA's Goddard Space Flight Center. His main project there is figuring out how to hurl spacecraft into orbit Frisbee-style. The spacecraft are small―about the size of birthday cakes. "This wouldn't work with big satellites or heavy space ships like the shuttle," notes Pete. But a cake-sized "nanosatellite" is just right. Nanosatellites―nanosats for short―are an exciting new idea in space exploration. Ordinary satellites tend to be heavy and expensive to launch. The cost alone is a deterrent to space research. Nanosats, on the other hand, can travel on a budget. For example, a Delta 4 rocket delivering a communications satellite to orbit could also carry a few nanosats piggyback-style with little extra effort or expense.
