LWS Architecture Committee
A Living With a Star Architecture Study
Enhancing our understanding of the Earth-Space system.
Honing our capability to predict potentially harmful phenomena.
Since its founding in 2001, NASA’s Living With a Star (LWS) program has sought a cross-disciplinary approach to enhance our scientific understanding of the Sun-Earth system and target aspects of that system that affect life and society. LWS missions have helped to achieve that overarching goal in the decades since, providing better predictive understanding of the Sun-Earth system, linkages between various solar, Earth and space systems, and space weather conditions both here at Earth and in the interplanetary medium.
These missions include Parker Solar Probe, which is unlocking the mysteries of the Sun’s atmosphere; the Solar Dynamics Observatory, which seeks to understand the Sun’s influence on Earth and near-Earth space; Solar Orbiter, which will capture the first-ever images of the Sun’s north and south poles; and Space Environment Testbeds, which seeks to study how to best protect satellites in space from solar variability.
With a new decade already in full swing, the NASA Science Mission Directorate Heliophysics Division (HPD) is reevaluating the LWS program’s current architecture with the aim to produce an updated framework that will continue the program into the next decade.
NASA has tasked the Johns Hopkins Applied Physics Laboratory (APL) with spearheading the Living With a Star Architecture Study, which brings together a committee of 10 heliophysics and space physics researchers. They will conduct and solicit inputs from the broader heliophysics community that will aid in creating a framework that will further LWS's goals and optimize new technology in its 10 strategic science areas (SSAs) as defined by the LWS Program Analysis Group (LPAG) and identified appropriate science objectives. These following strategic areas aim to enhance our understanding of the Earth-Space system and hone our capability to predict potentially harmful phenomena.
The committee is currently developing representative Focused Mission Topics (FMTs) for multiple SSAs. To ensure the LWS program will continue to fill current scientific gaps and meet scientific objectives with up-to-date models, technologies and strategies, the committee is seeking comments and input from the broader scientific community.
We would like your feedback on these items – you can find a feedback form for each SSA below. We recognize there is a lot of material there; feel free to comment (briefly if possible) on a subset of the items (even within an SSA or within a given science objective). The forms will be open from August 7-31.
From this material we will be forming Focused Mission Topics which will be presented for additional input later in the year. If you have any questions, please email us at SES-LWS-AC-Web@jhuapl.edu.
