ATK Composite Structures Support Study of Clouds

05 May 2006

Alliant Techsystems composite technologies supported last week’s successful launch of a Boeing Delta II rocket from Vandenberg Air Force Base, Calif.

The launch successfully placed the NASA satellites CloudSat and CALIPSO into orbit. As elements of both satellites, ATK composite structures will help scientists gather information on air quality and long-term climate issues.

An ATK-built antenna on CloudSat will collect radar pulses reflected from clouds to map their 3-D structure and ice/water composition for a better understanding of their effects on earth's climate. The CALIPSO instrument structure, fabricated by ATK, supports key satellite instruments, such as the telescope, star tracker, wide field camera, and shade assembly, all of which aid in precise measurement of aerosol distribution and transport around the world.
