- <p>Pegasus puts into orbit the first of a new class of small
- satellites
- </p>
- <p> The first satellites were tiny, antenna-studded devices that
- often weighed little more than the men and women who built
- them. But big was better as the space age progressed. The
- largest satellites today tip the scales at 15 tons, cost
- hundreds of millions of dollars and are roughly the size of
- Mack trucks. They must be put into orbit by giant rockets or
- space shuttles.
- </p>
- <p> But in the skies over California last week, a launch took
- place that broke all the rules. A diminutive rocket named
- Pegasus, built by a Virginia-based entrepreneurial firm called
- Orbital Sciences, dropped from under the wing of a B-52 and
- carried into orbit a small 200-kg (450-lb.) satellite, one of
- a new type of craft that promises to bring space history full
- circle. Called lightsats, the new payloads pack as much
- function into a few hundred kilograms as satellites many times
- their size. At $8 million a launch, they could open space to
- new military and industrial uses.
- </p>
- <p> The shrinkage has only begun. In July a second Pegasus is
- scheduled to launch seven 22.5-kg (50-lb.) communications
- satellites the size of car tires. And scientists are already
- dreaming about peppering space with swarms of
- "microspacecraft," each no bigger than a coffee can.
