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.
Mount Rushmore National Memorial under construction.
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.

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.

Washington, DC - On May 11, 2010 Secretary of the Interior Ken Salazar asked the National Academy of Engineering (NAE) and the National Research Council (NRC) to conduct an independent and science-based investigation of the root causes of the Deepwater Horizon oil spill. Today, the NAE-NRC review committee released its interim report.
“I appreciate the rigorous work the experts on the NAE and NRC team have undertaken to understand the root causes of the Deepwater Horizon oil spill,” said Secretary of the Interior Ken Salazar. “Their independent, science-based analysis of what went wrong in the lead up to the blowout will help guide our continuing efforts to raise the bar for safety and oversight of offshore oil and gas operations, and will be of assistance to other ongoing investigations. I look forward to receiving the team's final report and to the additional insight and recommendations they will be providing us over the coming months.”
“The interim report by the NAE and NRC team raises important questions they will be exploring further in their ongoing review” said Bureau of Ocean Management, Regulation and Enforcement (BOEMRE) Director Michael R. Bromwich. “Their work will help guide our continuing efforts to strengthen standards and oversight and underscores the importance of our ongoing efforts to build a strong and independent agency with the resources, training, and expertise to provide aggressive oversight of offshore oil and gas operations. I appreciate the time and expertise the NAE and NRC team are providing as we work towards ensuring that offshore energy production is conducted in a manner that protects human life and the environment.”
The NAE and NRC Committee reported that it expects to complete its final report by June, 2011.
