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.

LWS OBJECTIVES

Living With a Star is a cross-cutting program whose goals and objectives have the following links:

  1. Space Science: LWS quantifies the physics, dynamics, and behavior of the Sun-Earth system over the 11-year solar cycle.
  2. Earth Science: LWS improves understanding of the effects of solar variability and disturbances on terrestrial climate change.
  3. Human Exploration and Development: LWS provides data and scientific understanding required for advanced warning of energetic particle events that affect the safety of humans.
  4. Aeronautics and Space Transportation: LWS provides detailed characterization of radiation environments useful in the design of more reliable electronic components for air and space transportation systems.
