![]() This allows for an unprecedented number of observations and measurements to be taken over the same location at about the same time, but with different instruments collecting different types of data. ![]() For example, the A-Train constellation of Earth Observing Satellites circle the Earth collecting data, following one another on nearly-identical orbits, only seconds or minutes apart. NASA systems are engaged in observing our Earth, from land and ecosystem processes to the oceans to the atmosphere-all of the systems that help determine the Earth’s climate. With 14 operating satellites, 7 missions in development, and about 1700 Research Grants, NASA’s Earth Science program exceeds the combined efforts of all other Earth Science programs in the world. The Agency has spent over 20 years building spacecraft and collecting the measurements that are now used to model climate and the environment across the globe. NASA’s Earth Science program is one of the government’s best-kept secrets. Global Prediction, Monitoring, and Response Now, NASA has a unique opportunity to quickly apply these advanced technologies to the down-to-Earth challenge of creating clean, renewable energy systems for all of us. The Agency will continue to develop these technologies, making them smaller, lighter, and more efficient to meet the future needs of both human and robotic space exploration. Today, NASA brings to the table an extensive list of capabilities in the areas of photovoltaics, geothermal, wind power, fuel cells, batteries, solar power, power management and distribution, flywheels, Stirling/Brayton engines, alternate fuels (both biologically-derived and hydrogen-based), magnetic levitation, and thermoelectrics. In fact, NASA was a major player in the Federal response to the 1970s energy crisis, developing solar, wind, thermal reactor, efficient engine, and battery technologies. NASA’s basic research capabilities, applied science and engineering expertise, and strong systems engineering heritage, as well as extensive experience collaborating with other government entities (including DoE and DoD), industry, and academia all provide NASA with a unique ability to play a critical role in the planning and implementation of a national energy program. ![]() With fossil fuels reaching their limits of availability and desirability, and with climate change, air pollution, and national and international energy security at stake, the challenge of advancing alternative, clean energy sources may well be a matter of global survival. The extraordinary combination of information scientists, computer engineers, Earth and atmospheric scientists, astrobiologists, ecologists, nanotechnologists, modelers, robotics and sensor engineers, fluid dynamicists, life support researchers, and systems engineers has the potential to make a significant contribution to the vital transition from petroleum-based energy to sustainable, carbon-neutral energy sources. ![]()
