Living With a Star (LWS) is a NASA scientific program to study those aspects of the connected Sun-Earth system that directly affect life and society. LWS is a crosscutting initiative with goals and objectives relevant to NASA's Exploration Initiative, as well as to NASA's Strategic Enterprises. The program is managed by the Heliophysics Division of NASA's Science Mission Directorate. LWS is composed of three major components: Scientific investigations on spaceflight platforms study different regions of the Sun, interplanetary space, and geospace; an applied science program Space Environment Testbeds where protocols and components are tested; and a Targeted Research and Technology Program. ==Spaceflight Segment== The first two science missions have launched: Solar Dynamics Observatory (SDO) and Van Allen Probes. The SDO mission launched on February 11, 2010 and the Van Allen Probes mission launched on August 30, 2012. BARREL (Balloon Array for RBSP Relativistic Electron Losses) and Space Environment Testbeds (SET) are currently in development. Solar Orbiter Collaboration (SOC) and Solar Probe Plus (SPP) are in the formulation phase.〔(Living With a Star Program Missions )〕 Science requirements and conceptual mission implementation have been defined for the Ionosphere-Thermosphere Storm Probes (ITSP) and the Solar Sentinels. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Living With a Star」の詳細全文を読む スポンサード リンク
