BOULDER, Colo., Feb. 9 /PRNewswire-FirstCall/ -- Ball Aerospace
& Technologies Corp. has successfully completed stray light
testing of the Operational Land Imager (OLI) telescope assembly for
NASA's Landsat Data Continuity Mission. (Photo:

its kind stray light test was conducted at Ball's new Stray Light
Test Facility (SLTF) in Boulder, Colorado. The OLI instrument will
provide 15-meter (49ft.) panchromatic and 30m multi-spectral
earth-imaging spatial-resolution capability for the eighth mission
in the Landsat satellite series. Control of stray light is critical
to the quality of the OLI data product, requiring a level of
testing no other earth remote sensing instrument of this caliber
has undergone. The test included Point Source Rejection Ratio scans
obtained over a wide range of angles and for four telescope
configurations: open earth-view port, open and closed solar cal
port and aperture shutter closed. Demonstrating sensitivity over 10
orders of magnitude, the quality and repeatability of the data
proved that the OLI telescope has excellent margin on all on-orbit
stray light requirements. Ball's new SLTF is a Class 5 clean room
designed to eliminate undesired sources of background light and to
emphasize superior contamination control of the test environment.
The double cylindrical chamber reflects the specular light away
from the instrument under test. As the facility interior is nearly
all black, illumination sources can be either a solar simulator or
discrete laser wavelengths collimated into an 18-inch diameter
beam. The facility is designed to test a wide variety of
instruments up to approximately 2 meters per side and weighing up
to 1,100 pounds over a wide range of elevation and azimuth angles.
"The universal value of the Landsat program is inestimable," said
David L. Taylor, president and CEO of Ball Aerospace. "Testing of
OLI in Ball's stray light facility brings us closer to delivering
an instrument that will continue NASA's longest continuous imagery
data record of our planet." The Landsat program is a series of
Earth-observing satellite missions jointly managed by NASA and the
U.S. Geological Survey. For more than 36 years, Landsat satellites
have continuously and consistently collected images of Earth,
creating a historical archive unmatched in quality, detail,
coverage and length. The Ball Aerospace OLI instrument, slated to
launch in late 2012, includes a 185km swath allowing the entire
globe to be imaged every 16 days. The multispectral imagery is
gathered for applications that include agricultural monitoring,
natural resource management, land-use planning and climate science.
