NASA's Deep Impact Mission to Launch 29 November 2004 by Richard Conan-Davies One of the best ways of figuring our what's inside something is to break it open and take a look. That is what NASA is going to do with a comet as part of a project called Deep Impact. Although it has a name similar to a movie it's won't be quite as big. Due to launch on December 30th a spacecraft will be deployed to interecept the Comet called Temple 1 and then crash an "impactor" craft into the comet to create a hole equivalent to 4.2 tonnes of TNT. According to NASA, The Deep Impact mission aims to: Observe how the crater forms Measure the crater's depth and diameter Measure the composition of the interior of the crater and its ejecta Determine the changes in natural outgassing produced by the impact     This spacecraft , part of the Deep Impact Project, will crash into a comet to reveal it's insides. image: NASA
