Ball Aerospace Wins NASA Global Precipitation Measurement - Microwave Imager Study

March 31, 2003

Ball Aerospace & Technologies Corp. has been awarded one of three risk-reduction study contracts from Goddard Space Flight Center for the Global Precipitation Measurement -- Microwave Imager (GMI). GMI is an international effort managed by NASA to improve climate, weather, and hydrological predictions through more accurate and frequent precipitation measurements.

"GMI represents a great opportunity for Ball Aerospace to enhance our microwave sensor capability," said Gary Salisbury, manager of Microwave Sensor Activities for Civil Space Systems.

GMI will be used to make calibrated, radiometric measurements from space at multiple microwave frequencies and polarizations. GMI will be placed on the Global Precipitation Measurement (GPM) Core spacecraft together with the Dual- frequency Precipitation Radar provided by the National Space Development Agency of Japan. The Core spacecraft will make radiometric and radar measurements of clouds and precipitation and will be the central element of GPM's space segment.

A second GMI will be placed on the NASA-provided GPM Constellation spacecraft in order to provide more frequent sampling of precipitation events. The measurements made by the Core and NASA-provided Constellation spacecraft will be supplemented with measurements from other microwave radiometers located on satellites launched and operated by other U.S. agencies and GPM international partners.

Ball Aerospace & Technologies Corp. provides remote sensing systems and solutions to the aerospace and defense markets. It is a subsidiary of Ball Corporation which in addition to owning Ball Aerospace is one of the leading suppliers of metal and plastic packaging to the beverage and food industries. With the addition of Ball Packaging Europe, acquired in December 2002, Ball expects sales in 2003 of approximately $5.1 billion, $4.6 billion from its packaging segment and $500 million from its aerospace and technologies segment.
