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.

WASHINGTON, D.C. – Secretary of the Interior Ken Salazar today announced the winning college and high school teams that designed and built the most efficient portable wind turbine systems as part of the 2010 Indian Education Renewable Energy Challenge with the Argonne National Laboratory. The awards were presented today at the Interior Department's headquarters in Washington, D.C.
“I am proud to announce the winners of the first annual Student Energy Challenge and I welcome the partnership we have forged with Argonne National Laboratory,” Secretary Salazar said. “Finding unique and stimulating ways for students to translate their classroom learning to the real world is a key to developing our future scientists in Indian Country. In a few years, these students will be leaders in developing renewable energy resources for their tribes and the reservation economies.”
“I believe that innovation and creativity are important skills that Indian Country needs to achieve energy and economic sustainability,” said Assistant Secretary-Indian Affairs Larry Echo Hawk. “This youth initiative will help develop those skills by placing an emphasis on critical thinking and innovative design through science and engineering.”
At the college level, the first place award was shared by the Southwestern Indian Polytechnic Institute (SIPI) from Albuquerque, NM, and the College of Menominee Nation from Keshena, WI. At the high school level, the first place winner was the Oneida Nation High School from Oneida, WI.
The focus of the contest was to promote renewable energy development for Indian Country among students and teachers at the high school and college level. The contest is co-sponsored with the Bureau of Indian Education, the Indian Affairs Office of Indian Energy and Economic Development and the U.S. Department of Energy's Argonne National Laboratory.
“The Energy Challenge is a great opportunity for a team of students to use scientific and technical skills in a real-world application,” said Harold Myron, director of ANL's Division of Education Programs.
The challenge was a two-part contest. In Phase I, student teams organized by the schools were asked to submit designs for a portable wind turbine installation that generated energy, stored it mechanically or electronically and then used the stored energy to power an array of light emitting diodes. The best 10 designs (five high schools and five tribal colleges) were selected in the fall and those teams each received $1,300 to construct a prototype for Phase II. A panel of judges chose the winners based on their final constructed models and submitted videos.
“We support and encourage science and engineering programs to get Indian students engaged in renewable energy resources and we would like to congratulate all of the schools that participated in this initiative to make it a success," said Bart Stevens, acting director of the Bureau of Indian Education in the Interior Department.
