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.

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.

NEW YORK HARBOR, NY—Secretary of the Interior Ken Salazar today toured the Statue of Liberty National Monument and Ellis Island to assess safety and accessibility issues at the national park sites in New York Harbor. Sen. Robert Menendez (D-NJ), Rep. Anthony Weiner (D-NY) and Rep. Albio Sires (D-NJ) accompanied the Secretary.
“The Statue of Liberty is unique among our national parks as a symbol of freedom not only to Americans but also to people around the world,” Secretary Salazar said. “As a U.S. Senator and now as Secretary of the Interior, I believe the crown should be re-opened to the public if at all possible. I am here today to tour the statue and promise to work hard with the National Park Service to explore all feasible alternatives to reopening it.”
“We will explore all opportunities to re-open the crown while reducing risk to the public,” the Secretary emphasized. “I hope we can find a way. It would proclaim to the world – both figuratively and literally – that the path to the light of liberty is open to all.”
The Secretary also visited Ellis Island. Following the tragic events of Sept. 11, 2001, the National Park Service closed both the statue and Ellis Island to visitors. The Ellis Island Immigration Museum and Liberty Island were reopened on Dec. 20, 2001. The National Park Service conducted additional health and safety evaluations of both Liberty Island and the statue. After significant modifications to the pedestal and the addition of screening for visitors, access to the pedestal was re-opened in 2004. The crown, however, has remained closed.
The primary reason for the closure has been concern about the health and safety of visitors. The crown is accessible only by a narrow 168-step double-helix spiral staircase. The Park Service, which has responsibility to keep visitors safe and make it possible for them to evacuate in the event of an emergency, deemed the risk too high to re-open the crown to the public.
In 2008 Senator Salazar joined Senator Menendez and other Members of Congress in asking the National Park Service to conduct a study to determine what physical changes would be required to bring the statue's interior into compliance with safety and fire codes. If compliance is not possible, the study must determine how the National Park Service could minimize the safety risks to visitors, staff and emergency personnel.
A contract was awarded to Hughes Associates, a firm based in Baltimore, to conduct the study. The final report, expected mid-April 2009, will evaluate potential alternatives and cost estimates for accommodating public access in the statue's interior up to and including the crown.
Meanwhile, the National Park Service is working to establish an integrated alternative transportation system among the parks in the area to significantly enhance visitor access and experience.
