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.
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.
NASA Administrator, Interior Secretary to Attend LANDSAT Launch

WASHINGTON -- NASA Administrator Charles Bolden and Interior Secretary Ken Salazar will attend the launch of the Landsat Data Continuity Mission (LDCM) from Vandenberg Air Force Base in California on Monday, Feb. 11. The launch is scheduled for 10:02 a.m. PST.
LDCM is a collaboration between NASA and the Department of the Interior's U.S. Geological Survey. The mission will continue the Landsat program's 40-year continuous data record by Earth's landscapes by satellite from space. LDCM will expand and improve on that record with observations that advance a wide range of Earth sciences and contribute to the management of agriculture, water and forest resources.
Administrator Bolden and Interior's Assistant Secretary for Water and Science Anne Castle will meet with news media Sunday, Feb. 10, at Vandenberg's Atlas V/LDCM launch pad for interviews and a photo opportunity. The Atlas V rocket carrying the satellite will be visible within the gantry. A media escort will depart Vandenberg's South Base gate on Highway 246 and Arguello Boulevard for Space Launch Complex-3 at 2:45 p.m. on Sunday.
After launch Monday, Bolden and Salazar will meet with reporters at 11:30 a.m. at the NASA complex on the southern area of Vandenberg. Journalists interested in participating in this post-launch event and the televised news conference to follow will be escorted to NASA Building 840. The news conference will begin at noon.
Following the post-launch news conference, Bolden will visit the SpaceX launch pad at 1:30 p.m. The launch pad, which is being built at Space Launch Complex-4, will support the SpaceX Falcon 9 and Falcon Heavy rockets. In 2015, a Falcon 9 rocket will launch the Jason-3 sea surface monitoring mission from Vandenberg.
Media interested in attending these events must contact Lt. Kaylee Ausbun at 805-606-6159 or Kaylee.Ausbun@us.af.mil by noon Friday, Feb. 8.
NASA's Goddard Space Flight Center manages the LDCM Project. Orbital Sciences Corp. built, integrated, and tested the spacecraft. NASA's Launch Services Program at the agency's Kennedy Space Center in Florida is managing the launch. United Launch Alliance supplied the Atlas V rocket. After launch and the initial checkout phase, the U.S. Geological Survey will take operational control of the satellite, and LDCM will be renamed Landsat 8.
