For Immediate Release

Scientists believed comets were filled with ice, dust and perhaps the building blocks of life, but traditionally their make-up had been a mystery. It wasn’t until the 2005 NASA Deep Impact mission that scientists were finally allowed their first peek inside a comet.

A comet's make-up is still a mystery. Scientists believe they're filled with ice, dust, and perhaps the building blocks for life, but they've never been able to get an up close and personal look. On July 3, 2005 all of this will change with a mission dubbed "Deep Impact."
