Delving into the ionosphere-thermosphere system on a truly global scale: For the first time, we'll be undertaking a comprehensive analysis of the ionosphere-thermosphere that spans the entire globe. This will enable a thorough understanding of these crucial atmospheric layers, which interact with solar wind, support satellite operations, and facilitate long-distance communication.

Tracing the transport of energy and momentum: Our studies will focus on tracking the pathways of energy and momentum, particularly as they cross boundaries within the ionosphere and thermosphere. This will deepen our knowledge of atmospheric dynamics and the effects of space weather phenomena like solar storms.

Unraveling the feedback mechanisms: We aim to pinpoint and understand the feedback mechanisms in the ionosphere/thermosphere and magnetosphere. Determining these intricate interplays will help us predict how changes in one layer may affect others, further enhancing our models of space weather and climate.

Exploring cross-scale coupling across diverse spatial and temporal scales: Our approach considers the complex interactions across a variety of scales. Recognizing the significance of cross-scale coupling will allow us to understand the vast network of interactions within these atmospheric layers, creating a more cohesive model of our near-Earth space environment.

Building the scientific foundation for NASA's role in the National Space Weather Action Plan: We're providing pivotal research that strengthens NASA's contribution to this national initiative. Our work will bolster the understanding and prediction of space weather phenomena, which have significant impacts on our technology-dependent society.

Investigating structure/processes impacting navigation/communication in the ionosphere: We're delving into the complexities of the ionosphere and its influence on vital systems. By studying its structure and processes, we aim to address issues related to GPS navigation, satellite communication, and long-range radio transmissions that this layer of our atmosphere affects.

Studying structure/processes impacting satellite orbit decay and prediction in the thermosphere: The thermosphere, where most satellites reside, is our area of focus. We're scrutinizing its structure and processes to enhance the understanding of satellite orbit decay, which impacts satellite lifespan, and to improve accuracy in satellite orbit prediction.

Energetic particle precipitation, satellite anomalies, and human radiation exposure: Our research explores the relationship between energetic particle precipitation and its effects, including satellite anomalies and radiation exposure risks for astronauts and high-altitude pilots. This understanding is crucial for protecting human life and ensuring the safe operation of satellites.
