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.
Martin Luther King Jr. Memorial Becomes 395th National Park
WASHINGTON, DC –The National Park Service formally welcomed the Martin Luther King, Jr. Memorial as America's 395th national park on August 28 – the 48th anniversary of Dr. King's “I Have a Dream” speech, delivered in 1963 on the steps of the Lincoln Memorial. The National Park Service also emphasized its commitment to working closely with the Martin Luther King, Jr., Memorial Foundation to reschedule the ceremonial dedication planned for Sunday that was unfortunately postponed due to Hurricane Irene.
“Welcoming this memorial to the National Mall honors a heroic man and a critical chapter in our nation's march toward a more perfect union,” said Secretary of the Interior Ken Salazar. “Martin Luther King, Jr., mobilized the power of faith and morality to break the chains of oppression that held our nation back. I commend the MLK Foundation and Harry Johnson for their tireless work in making this memorial a reality, so that we may always be reminded of the work that is yet to be done to achieve Dr. King's dream and a more perfect union.”
“Forty-eight years ago, Dr. King took to the steps of the Lincoln Memorial and challenged our nation to fulfill his dream of equality for all Americans,” said the National Park Service Director Jonathan B. Jarvis. “On the anniversary of that speech, we are proud to add the Martin Luther King, Jr. Memorial to National Park System as a lasting tribute to this American hero. We look forward to working with the MLK Foundation to reschedule the formal dedication and hope that many of the tens of thousands of people who had planned to attend will be able to participate.”
In 1996, Congress authorized Dr. King's fraternity, Alpha Phi Alpha, to establish a memorial to the civil rights leader in Washington, DC. The group formed the Martin Luther King, Jr. National Memorial Project Foundation and held a competition for the design. A site along the Tidal Basin of the National Mall was chosen for the memorial.
After 15 years of effort, a granite likeness of Dr. King emerges from the memorial's Stone of Hope and stands resolutely between iconic monuments to Thomas Jefferson and Abraham Lincoln.
“From World War II to Vietnam Veterans, from Lincoln to Jefferson and now to King, the memorials and monuments along the National Mall are where millions of visitors every year learn about our history,” said Bob Vogel, superintendent of the National Mall and Memorial Parks. “The National Park Service is honored to serve as the keeper of America's story, and with this new memorial, to have this incredible venue from which to share the courage of one man and the struggle for civil rights that he led.”
The memorial to Dr. King is part of the National Mall and Memorial Parks and is open to the public. National Park Service rangers provide programs for visitors and answer questions. For more information and photographs, please see http://www.nps.gov/mlkm.
