STARDUST
LISTEN TO STARDUST
On February 7, 1999, NASA launched the Stardust spacecraft. Its mission was to collect samples of a comet called Wild 2 and return them to earth for analysis. The particles it was to collect were dust formed around other stars – dust estimated to be older than our sun. These particles were called Stardust.
It was discovered that these very rare Stardust particles were some of the early building blocks of our solar system. The comet’s ice was formed in cold regions around Neptune yet the rock comprising most of the comet’s bulk formed close to the sun, an area so hot that its heat can melt bricks.
Stardust taught us much, including the fact that comets are a mixture of materials made by conditions of both fire and ice.
