Multimedia News Release - Ball's Deep Impact Spacecraft Prepares to Meet Comet Tempel 1

June 27, 2005

In one of the most daring deep space missions NASA has ever undertaken, the Deep Impact spacecraft, designed and built by Ball Aerospace & Technologies Corp., is entering the final days of a six-month journey to reach comet Tempel 1 on Independence Day. Approximately 24 hours before the encounter, the Impactor spacecraft will separate from the Flyby spacecraft and autonomously move directly into the path of the approaching comet. The encounter with Tempel 1 will occur nearly 83 million miles from Earth and at closing speeds approaching 23,000 miles-per-hour.

"Deep Impact is a highly technical and complicated mission," said David L. Taylor, president and CEO of Ball Aerospace. "Together with our teammates at NASA, JPL and the University of Maryland, we built a one-of-a-kind spacecraft to expand our knowledge of comets," Taylor added.

The Impactor is expected to vaporize upon impact. The kinetic energy of the collision is expected to create a crater the size of a football field and propel material from the comet's nucleus into space. Deep Impact's telescopes, cameras and spectrometer aboard the Flyby spacecraft will monitor the impact from a vantage point of about 300 miles away and return data on the pristine material in the crater and other surface material ejected by the impact. The Flyby spacecraft's Medium Resolution Imager (MRI) and High Resolution Imager (HRI), the latter which is the largest interplanetary telescope ever flown, will record the details of the collision. The Impactor spacecraft will also provide close-encounter photos of the comet just prior to collision, giving scientists the most complete view of a comet to date.

The impact will be observed by multiple Ball-built cameras. In addition to the instruments on the Deep Impact spacecraft, NASA's Hubble, Spitzer and Chandra observatories will also capture images of the event. Ball produced key technologies for all three of these missions.

Ball Aerospace developed and integrated the Flyby spacecraft, the Impactor spacecraft, and science instruments, including three telescopes, three cameras and a spectrometer for analyzing the interior of the comet. Deep Impact is the eighth mission in NASA's Discovery Program, and the first mission to attempt to impact with a comet nucleus in order to probe beneath its surface.
