Aerospace Support to Global Climate Research

Aerospace Support to Global Climate Research In addition to its primary mission to support defense and intelligence space system development, The Aerospace Corporation supports civil and commercial space activities, many of which involve global climate research. Most notable is the U.S. Geological Survey (USGS) Landsat program. Initially launched in 1972, the first Landsat missions were […]  More »

Feasibility of Space-Based Monitoring for Governance of Solar Radiation Management

Feasibility of Space-Based Monitoring for Governance of Solar Radiation Management Preliminary analysis at Aerospace suggests that detecting tests of particle injection schemes from space will be quite challenging, especially for unannounced small-scale, localized trials with short- term observable effects. Patrick L. Smith, Leslie A. Wickman, Inki A. Min, and Steven M. Beck Climate researchers and […]  More »

Utility-Scale Geothermal Production at Military Bases

Utility-Scale Geothermal Production at Military Bases Geothermal energy has a significant role to play at many military bases. The U.S. Navy, for instance, currently produces 250 megawatts from its Coso geothermal field near Ridgecrest, California—enough energy to serve approximately 190,000 homes. Not only does the Navy generate free electricity for the base, it produces over […]  More »

Why Geothermal Energy?

Why Geothermal Energy? Four main factors make geothermal energy appealing: geothermal kilowatt hours are generally cost competitive with conventional sources of energy; the production of geothermal energy is not associated with significant release of greenhouse gases or waste generation; unlike solar and wind power, geothermal power is predictable and typically supplies uninterrupted energy; and the […]  More »
