NASA’s Atmospheric Waves Experiment (AWE) is embarking on a groundbreaking mission that aims to shed light on the intricate interactions between terrestrial weather and space weather. This exploration is of utmost significance as our reliance on satellite-based services for navigation and communication continues to grow. Accurate forecasts and data on space weather are essential for ensuring the smooth operation of these vital services.
At the heart of the AWE mission lies the investigation of one of the primary drivers of space weather – Earth’s weather itself. Central to this undertaking is a focus on Atmospheric Gravity Waves (AGW), a fascinating type of vertical wave generated by extreme weather events or sudden disturbances that cause stable air to shift vertically. These waves, including AGWs, have a profound influence on space weather and affect overall weather patterns, climate, and space conditions.
To capture these elusive phenomena, the AWE mission will measure airglow at the mesopause, which is located at an altitude of 85 to 87 kilometers above Earth. Airglow is the faint light emitted by atoms and molecules in Earth’s upper atmosphere. The mission will employ an innovative instrument called the Advanced Mesospheric Temperature Mapper (ATMT), which will scan the mesopause and map the brightness of light at specific wavelengths, providing invaluable insights into AGWs and their impact.
Space weather, a term unfamiliar to many, refers to the environmental conditions around Earth and other celestial bodies that are influenced by the activities of the Sun. These activities include solar flares, emissions, and the dynamic nature of matter in space. Severe space weather events can have far-reaching consequences, potentially affecting critical Earth-based installations such as satellite-based communication systems, radio communication networks, navigation systems, and power grids.
Through the data and knowledge gained from the AWE mission, scientists and researchers will be better equipped to understand the dynamics of atmospheric waves and their role in shaping space weather. This understanding will advance our ability to predict and mitigate the impact of space weather phenomena on our technological infrastructure, ensuring the continued functionality of vital services that we rely on every day.
