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.
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.
Salazar Signs First U.S. Offshore Commercial Wind Energy Lease with Cape Wind Associates, LLC
Office of the Secretary

ATLANTIC CITY, NJ — Secretary of the Interior Ken Salazar and Cape Wind Associates, LLC today signed the nation's first lease for commercial wind energy development on the Outer Continental Shelf (OCS).
“This is the beginning of a new era for our Nation in offshore energy production,” Secretary Salazar said in a speech to the American Wind Energy Association in Atlantic City, New Jersey, where he signed the lease. “Responsibly developing this clean, renewable, domestic resource will stimulate investment in cutting-edge technology, create good, solid jobs for American workers, and promote our nation's competitiveness, security, and prosperity.”
“This is an important milestone in the development of offshore wind energy,” said Bureau of Ocean Energy Management, Regulation and Enforcement (BOEM) Director Michael R. Bromwich, whose agency is responsible for reviewing proposed renewable energy projects on the OCS. “This is the first chapter of what we hope will be a continuing story of offshore renewable energy development that will allow us to expand the nation's energy resource portfolio. As we move forward, we hope to expedite the process of reviewing and approving such applications.”
The area offered in the lease is comprised of 25 square miles on the OCS in Nantucket Sound offshore Massachusetts. The 130 planned wind turbines could generate a maximum electric output of 468 megawatts with an average anticipated output of 182 megawatts. At average expected production, Cape Wind could produce enough energy to power more than 200,000 homes in Massachusetts. The site of the project on Horseshoe Shoals lies outside shipping channels, ferry routes and flight paths but is adjacent to power-consuming coastal communities.
The Cape Wind energy project would be the first wind farm on the OCS, potentially generating enough power to meet 75 percent of the electricity demand for Cape Cod, Martha's Vineyard and Nantucket Island combined.
The 28-year lease for the area off the coast of Cape Cod, Mass. will cost the company $88,278 in annual rent prior to production, and a 2 to 7 percent operating fee during production. The fee is based on revenues from selling the offshore wind energy in regional markets.
On April 28, 2010, Secretary Salazar signed the Record of Decision for the Cape Wind project, which paved the way for BOEM's decision to issue a commercial wind lease to Cape Wind Associates, LLC, a subsidiary of Energy Management Inc. The Record of Decision reflects the commitments that the company must satisfy to ensure that the company's lease activities are conducted in a manner that prevents or minimizes impacts on environmental or cultural resources.
The project site is about 5 miles from the mainland shoreline, 13 miles from Nantucket Island, and 9 miles from Martha's Vineyard. One-fifth of the offshore wind energy potential of the East Coast is located off the New England coast, and Nantucket Sound receives strong, steady Atlantic winds year round. The project includes a 66.5-mile buried submarine transmission cable system, an electric service platform and two 115-kilovolt lines connecting to the mainland power grid.
