 Stardust Collector

NASA's Stardust spacecraft has successfully deployed a device that will collect extremely small particles in space.

The particles are called dust.

They form a stream of particles that flows through our solar system.

The special device will collect the particles until May 25.

After that,the collection device will be returned inside the spacecraft.

The collection device will remain inside Stardust until 2002 when it will again deploy the device and continue collecting the particles.

The device Stardust deployed will also be used to collect dust from a comet named Wild-2.

Wild-2 will pass near the spacecraft in 2004.

The Stardust spacecraft was launched in February,1999.
