ICESAT Spacecraft Checkout Complete

March 06, 2003

Commissioning of the Goddard Space Flight Center's Ice, Cloud and Land Elevation Satellite (ICESat) was completed on Thursday, Feb. 20 with the successful first firing of its laser altimeter. Ball Aerospace & Technologies Corp. built the ICESat spacecraft.

ICESat's sophisticated equipment has been checked out in a methodical progression monitored by the system's designers. Once the flawless performance of its satellite bus was established in January, ICESat moved to the instrument calibration orbit, and the elements of the Geoscience Laser Altimeter System (GLAS) were turned on in sequence. GLAS is now recording ice height measurements and land elevations as it orbits the Earth every hour and a half.

"When the laser came on, it lit up a smile on the face of everyone associated with ICESat," said Zubin Emsley, the satellite's program manager for Ball Aerospace. "It's the culmination of years of effort by a talented and dedicated team, and puts a spectacular new instrument to work to understand environmental change."

The focus of the operations is now on fine-tuning and calibration of GLAS. Ball Aerospace will continue to operate ICESat throughout the mission as the focus of ICESat operations transitions to NASA and the science team. Calibrated on-orbit measurements are expected by early summer.

As part of NASA's Earth Observing System, the primary role of ICESat is to quantify the growth or retreat of the ice sheets covering Antarctica and Greenland over a five-year period. The mission is designed to answer questions concerning many related aspects of the Earth's climate system, including global climate change and changes in sea level.

The Ball Commercial Platform (BCP) 2000, built by Ball Aerospace for ICESat is specifically designed for remote-sensing missions, and was also used for the QuikSCAT and QuickBird missions. NASA's Goddard Space Flight Center designed and built the GLAS for ICESat.

Ball Aerospace & Technologies Corp. provides remote sensing systems and solutions to the aerospace and defense markets. It is a subsidiary of Ball Corporation [NYSE: BLL] which in addition to owning Ball Aerospace is one of the leading suppliers of metal and plastic packaging to the beverage and food industries. Ball expects sales in 2003 of approximately $5.1 billion.
