Last Sunday, after seven years in space traveling nearly three billion miles, Stardust landed in the Great Salt Lake Desert with a treasure from when the solar system formed 4.6 billion years ago. We should have more than one million particles larger than one micron in diameter.
It exceeded all of our grandest expectations. We should have more than 1 million particles larger than 1 micron in diameter.
The prediction was that we would get a dozen particles larger than human hair size and one particle a little bit larger than a millimeter.
