Summary

The original finding aid described this as:

Description: STS-46's Earth observation taken aboard Atlantis, Orbiter Vehicle (OV) 104, is of the Earth's limb near sunrise at an Orbiter altitude of 128 nautical miles from a position just to the northeast of the Hawaiian Islands. The limb appears thicker than in most photographs from previous missions due to the use of a 350m focal length lens. The black parts of the image are the unlit Earth in the foreground and the darkness of space above. The uppermost layers of the atmosphere appear dark blue due to molecular scattering of solar rays. Beneath the blue is a white layer within which a thin, stratified layer of suspended scattering material can be identified. The greyish-red band is residue of the Mt. Pinatubo eruption of June 1991 comprised of a combination of ash and sulfuric acid particles at an altitude of 20 to 27 kilometers above the Earth. The boundary between the grey-red and lighter colored red is the lower stratosphere. The clouds visible are cirrus at 40, 000 foot altitude. Below the stratosphere the lower atmosphere appears darker red because of scattering by dust, water, vapor and smoke.

The objects in this collection are from The U.S. National Archives and Defense Visual Information Distribution Service. The U.S. National Archives and Records Administration (NARA) was established in 1934 by President Franklin Roosevelt. NARA keeps those Federal records that are judged to have continuing value—about 2 to 5 percent of those generated in any given year. There are approximately 10 billion pages of textual records; 12 million maps, charts, and architectural and engineering drawings; 25 million still photographs and graphics; 24 million aerial photographs; 300,000 reels of motion picture film; 400,000 video and sound recordings; and 133 terabytes of electronic data. The Defense Visual Information Distribution Service provides a connection between world media and the American military personnel serving at home and abroad. All of these materials are preserved because they are important to the workings of Government, have long-term research worth, or provide information of value to citizens.
