An active nutation damper for spacecraft

An active nutation damping device, consisting of an angular accelerometer, a dc-motor-driven flywheel, and associated electronics, developed for spacecraft use is described. This damping system was used on the LAGEOS spacecraft to control nutation buildup during the long coast period (approximately 75 minutes) after the third stage separation. The damper package was evaluated and proven on a three-axis gas-bearing simulator that duplicated the LAGEOS spacecraft critical flight dynamics. In addition, a failure analysis of the damper assembly was performed. Performance of the damper during the LAGEOS flight has confirmed the preflight evaluation and analysis

The transformation of Port Gamble Bay: from remediation to restoration

For over 140 years, a lumber mill operated at the mouth of Port Gamble Bay producing lumber and other wood products, and leaving behind a legacy of contamination and degraded habitat when it closed its doors in 1995. Fast forward to the present when state and federal agencies, local government, tribes, community groups, and industry teamed up to cleanup, restore and preserve the bay’s high-quality natural resources. Undertaking extensive cleanup and the largest creosote-treated piling removal effort in the Puget Sound, Pope Resources removed contaminated sediment, over 8,500 creosote-treated pilings and numerous overwater structures to improve over 3,000 feet of shoreline and over 100 acres of aquatic habitat. Complimentary to cleanup, Ecology partnered with public and private entities, tribes, and the community to preserve nearly 2,000 acres of forest land and tidelands, remove derelict debris and vessels throughout the bay, and restore native oysters. Today the bay provides a cleaner and healthier place for community members and visitors to work, live and play

Restoring a Forest Watershed and Adding Water Back to the Land

Historical evidence clearly shows a significant decline in both stream flow and ground water recharge in the Sacramento Mountains of southern New Mexico. Photos, oral history, early Census data, and written accounts all paint a much wetter picture than is present today. Dense forests are robbing springs and streams of surface flow. Ground water recharge during the recent drought was non-existent. Large numbers of wells all over Otero County dried up. Drilling deeper was successful in some areas, but people in some areas are still hauling water. Members of the Sacramento River Watershed Coalition recently completed several large thinning projects near Timberon. Several thousand acres of Ponderosa pine and alligator juniper have been thinned and restored to historical tree densities. Trees were thinned on both private and State Land using Senator Jeff Bingaman’s Forest Restoration funds, State Forestry Wildland/Urban Interface funds, NRCS Environmental Quality Incentive Program cost share, BLM, and the rancher’s input. Tree densities were reduced to improve ground cover and reduce danger of a crown fire
