Living With A Star

The Living With a Star (LWS) program emphasizes the science necessary to understand those aspects of the Sun and the Earth's space environment that affect life and society. The ultimate goal is to provide a predictive understanding of the system, and specifically of the space weather conditions at Earth and in the interplanetary medium.

LWS missions have been formulated to answer specific science questions needed to understand the linkages among the interconnected systems that impact us. LWS products impact technology associated with space systems, communications and navigation, and ground systems such as power grids.The coordinated LWS program includes strategic missions, targeted research and technology development, a space environment test bed flight opportunity, and partnerships with other agencies and nations.
Living With A Star

Who would have ever thought to consider our own Sun as a member of the Cosmos,  as a Star?

Solar Probe Fact Sheet(click on Image)

Solar Probe+ will be an extraordinary and historic mission, exploring what is arguably the last region of the solar system to be visited by a spacecraft, the Sun’s outer atmosphere or corona as it extends out into space. Approaching as close as 9.5 solar radii* (8.5 solar radii above the Sun’s surface), Solar Probe+ will repeatedly sample the near-Sun environment, revolutionizing our knowledge and understanding of coronal heating and of the origin and evolution of the solar wind and answering critical questions in heliophysics that have been ranked as top priorities for decades. Moreover, by making direct, in-situ measurements of the region where some of the most hazardous solar energetic particles are energized, Solar Probe+ will make a fundamental contribution to our ability to characterize and forecast the radiation environment in which future space explorers will work and live. See:Solar Probe Plus

As with anything if we want peer deeper in the construction of the world around us it is necessary sometimes to put on different glasses for different perspectives. So it is about how we can look at the universe around us.
