Ball Aerospace & Technologies Corp., has been selected by NASA’s Goddard Space Flight Center (GSFC) for the first phase of a study to develop a satellite bus designed for the Global Precipitation Measurement (GPM) mission. The study will conclude in November,in anticipation of final selection by NASA in January 2005.

The selection will be made through the Goddard Rapid Spacecraft
Development Office (RSDO). Ball Aerospace has been selected for three RSDO
contracts in recent years, including the spacecraft for the Quick
Scatterometer (QuikSCAT); the Ice, Cloud and Land Elevation Satellite
(ICESat); and the NPOESS Preparatory Project (NPP). The Ball Aerospace
Commercial Platform 2000 (BCP 2000) was selected for all three missions.

GPM is a joint mission with the Japan Aerospace Exploration Agency (JAXA)
and other international agencies. It is one of the next-generation of
systematic measurement missions that will calculate precipitation, a key
climate factor, with improved temporal resolution and spatial coverage.

“We have shown that we can accommodate specific program needs within the
context of the RSDO offering,” said Zubin Emsley, director of commercial
program development for Ball Aerospace. “Successful builds on the already
launched QuikSCAT and ICESat make this a good fit for us.”

Ball Aerospace has been involved in the development of instrumentation for
this mission for several years. In 2003, Ball Aerospace was awarded a study
contract from Goddard for the Global Precipitation Measurement — Microwave
Imager (GMI), to fly aboard the GPM spacecraft. This instrument will
complement the JAXA contributions, making radiometric and radar measurements
of clouds and precipitation.

GPM will build upon the success of the Tropical Rainfall Measuring Mission
(TRMM) with a goal of improving weather and precipitation forecasts through
more accurate measurement of rain rates and latent heating; and to provide
more frequent and complete sampling of the Earth’s precipitation.

Ball Corporation is a supplier of high-quality metal and plastic packaging
products and innovative packaging solutions to the beverage and food
industries. The company also owns Ball Aerospace & Technologies Corp., which
develops sensors, spacecraft, systems and components for the government and
commercial markets. Ball employs 13,100 people worldwide and reported 2003
sales of $4.9 billion.
