Henderson DUSEL: "Unearthing the secrets of the Universe, Underground" ===================================================================== The HUSEP (Henderson Underground Science and Engineering Project) collaboration was formed in April 2004 for the purpose of establishing an underground science and engineering lab at the Henderson Mine, Empire, Colorado, owned by the Climax Molybdenum Company, a subsidiary of the Phelps Dodge Corporation. The collaboration is a national organization that has representatives from Henderson Mine, the science and engineering departments of several regional and national universities. NSF has endorsed the value of a Deep Underground Science and Engineering Laboratory (DUSEL) that will offer an exciting opportunity to illuminate the dark side of Earth, life, and the cosmos. It will allow us to answer fundamental physics questions as to the nature of dark matter, the properties of the neutrinos and the stability of matter. It will provide a unique observatory to explore the microbial processes and evolution under our planet's surface and the complex connection between tectonics, rock properties and multifaceted reaction and transport phenomena. It will enable a dramatic improvement in underground construction, resource extraction and environmental remediation industries. DUSEL will also provide unique opportunities for cross-disciplinary education and outreach and for involvement of minority-serving institutions and local communities.
