Science For a Hungry World | NASA Goddard Spaceflight Center
If a particular region is going to have a bad harvest, FEWS NET looks at the strength of the community. They look at how much was produced in previous years. Is this the first bad year after many good years or is it the fifth bad year in a row? So it's all about context. If we understand the context, we can then provide accurate early warning of a crisis before it comes down the pike."
"Satellite remote sensing, particularly with vegetation, because of its certainty and reliability across space and time has really come to be absolutely critical in trying to determine when there's a problem. and when action is required. Having that early look at production that we get from remote sensing observations is critical to having the pieces in place and the analysis done and the people forewarned so that if there is a requirement for sending out food assitance, we will have all the little pieces in place so that we can do that in a rapid way."
Planetary Skin - Cisco's Video Story
“Planetary Skin is a massive system for global-monitoring of environmental conditions that will enable effective decision making in the private and public sectors and in communities, using data collected from myriad sources including space, airborne, maritime, terrestrial and people-based sensor networks. Data will be analyzed, verified and reported over open standards-based Web 2.0 and 3.0 collaborative spaces for decision makers.”
Powering the Planet - Space Based Solar Power (Space Futures Channel)
On October 10, 2007, a report was released by the Pentagon on the feasibility of developing space solar power systems that transmit unlimited energy to Earth. This 20 minute video provides an overview of current concepts and development in this area which, if it could be developed, would provide a new major clean power source for the planet and produce major commercial benefits.
