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.
SHANKSVILLE, Pa. -- Secretary of the Interior Sally Jewell today joined Flight 93 Memorial Superintendent Jeff Reinbold, Flight 93 Families President Gordon Felt, Dr. Brent Glass, Flight 93 Advisory Board Commissioner and National Park Service employees, volunteers and families in honoring the 40 passengers and crew of United Flight 93 and all those who lost their lives on September 11th.
The observance of Flight 93 and September 11th took place at the Flight 93 National Memorial. The memorial in Shanksville includes a memorial plaza and wall of names, a ring road that encircles the Field of Honor, and a visitor contact station.
Yesterday, Secretary Jewell helped break ground on the next phase of the memorial, which will include a visitor and education center, 40 memorial groves each with 40 trees, and a walkway that follows the ring road down to the Field of Honor and the crash site. The new visitor center is expected to be completed in September 2015.
The National Park Foundation raised more than $40 million dollars to begin construction on the visitor center. The Friends of Flight 93 will continue to fundraise toward additional operational and programmatic needs.
Below please find Secretary Jewell's remarks as prepared for delivery:
Each of us here today remembers September 11, 2001.
We remember where we were, the horror we felt as we watched the images on television, and the terrible aftermath of pain and sorrow.
For the families of the 40 and thousands of other families impacted that day, you have known the terrible pain of loss.
A well-known verse reminds us “greater love has no one than this: to lay down one's life for his friends.” We never know when we might be called upon to lay down our lives for others. Certainly the heroes of Flight 93 had no idea that they would be heroes or that they would lay down their lives for their nation that day.
But their actions likely saved the lives of untold people in Washington and protected the very symbol of liberty and democracy that fuels the hatred of terrorists: the U.S. Capitol.
This Memorial we are surrounded by today protects and honors the remains of these heroes and ensures that generations from now, the story of Flight 93 will still remind and inspire those who come after us.
It is a testament to the 40 that 300,000 people a year visit this place of honor and more than 100,000 people have donated to build the Memorial.
Thank you to the Families of Flight 93, the Flight 93 Advisory Commission, the Flight 93 Memorial Task Force, Friends of Flight 93 and the National Park Foundation for your tireless work to create a memorial to honor these heroes.
While the formal partnership that created this Memorial has concluded its work, the spirit of that partnership will continue. The partners have given the nation a wonderful gift – not only a fitting tribute to the passengers and crew of Flight 93, but an opportunity to participate in the making of the Memorial.
I want to thank the local community and volunteers who have welcomed us as a new neighbor, and who are working with us to ensure people know of this place and of the important events that happened in the skies above us.
The National Park Service has the sacred responsibility of managing this site on behalf of the families, our partners and all the American people. We are in the forever business and we will protect this hallowed ground, the final resting place of your loved ones, and make sure future generations know this important story.
