Mercury's surface in "enhanced color," a color scheme created to emphasize color differences. This is not what Mercury would look like to the human eye, but by applying mathematical analysis to images, color differences can be accentuated beyond those visible to a person.

The workers had to endure conditions that varied from blazing hot to bitterly cold and windy. Each day they climbed 700 stairs to the top of the mountain to punch-in on the time clock. Then 3/8 inch thick steel cables lowered them over the front of the 500-foot face of the mountain in a "bosun chair." Despite the dangers, no one was killed during the project.
Otters in Glacier Bay National Park and Preserve, Alaska.
The sea otter population of Glacier Bay has increased dramatically in the past 20 years. Ecologists consider sea otters a keystone species here. Otters consume vast quantities of clams, urchins, crabs, and other invertebrates and their presence creates ripples through the ecosystem. NPS photo.
Every day someone like you becomes a wildland wildfire fighter, a teacher, a trail-builder, a museum curator, or a park ranger. Discover your opportunities in national parks. Come to play. Come to learn. Come to serve. Develop your environmental leadership skills. Find a job. Be the next generation to preserve and protect these great places.
With more than 80% of Americans living in urban areas, urban parks are more important than ever. The father of American landscape architecture, Frederick Law Olmsted, said of urban parks:
It is one great purpose of the Park to supply to the hundreds of thousands of tired workers, who have no opportunity to spend their summers in the country, a specimen of God's handiwork that shall be to them, inexpensively, what a month or two in the White Mountains or the Adirondacks is, at great cost, to those in easier circumstances.
Interior Continues Leadership Role in Land Remote Sensing Under National Space Policy Announced by the President
Office of the Secretary Policy Management and Budget

WASHINGTON, D.C. – The National Space Policy announced by the White House today recognizes and endorses the Department of the Interior's expertise and accomplishments in land imaging and remote sensing to advance global climate change research and provide data for science and natural resource management.
“The National Space Policy confirms Interior's important role in land imaging and remote sensing in coordination with NASA,” said Interior Assistant Secretary Anne Castle. “The unbiased, comprehensive data this program provides is vital to our efforts to better understand and manage land, water, and our natural resources. We look forward to working with government agencies at all levels — Federal, State, local and tribal —to promote a broad, public understanding of land and water conditions in our Nation and around the globe.”
“Land remote sensing is a crucial tool in our efforts to develop broad, effective, holistic approaches to both mitigate and adapt to the environmental challenges of our day,” said Castle, who oversees Interior's Water and Science agencies, including the U.S. Geological Survey. “In addition, remote sensing has critical event-specific uses, for example, in closely monitoring the BP oil spill in the Gulf of Mexico and establishing baseline and post-spill conditions.”
Since 1966, Interior has managed science data operations and applications development for Landsat and other national land imaging systems from its U.S. Geological Survey Earth Resources Observation and Science Center in Sioux Falls, SD. The Department currently operates Landsats 5 and 7 and is developing the Landsat Data Continuity Mission with NASA for launch in FY 2013. The Administration is currently discussing plans for Landsat 9.
With its historical consistency, continuous global coverage, and very high quality of data, Landsat has become a vital tool worldwide for understanding scientific issues related to land use and natural resources. International applications of Landsat data have become widespread for use in agriculture, forestry, mapping, land and water assessments and climate change study.
The Department of the Interior, through the U.S. Geological Survey, facilitates access by U.S. civil agencies to national security satellite data when this data can be used for environmental assessments and disaster management. The Landsat series of satellites also is considered a cornerstone of U.S. space cooperation with foreign nations. More than 20 nations on six continents collaborate in operating local receiving stations for Landsat data on behalf of their continental regions.
On behalf of the Department, USGS publishes the entire 38-year Landsat archive over the Internet at no cost to users. In the past two years, more than 2 million current and archived images taken by Landsat have been downloaded by users throughout the world.
