NASA is closely monitoring Earth's upper atmosphere this fall, focusing on several key phenomena that influence space weather and atmospheric conditions. The agency's research encompasses the ionosphere, thermosphere, and mesosphere, utilizing data from missions like ICON (Ionospheric Connection Explorer), GOLD (Global-scale Observations of the Limb and Disk), and TIMED (Thermosphere Ionosphere Mesosphere Energetics and Dynamics). These missions provide valuable insights into how the upper atmosphere responds to solar activity and geomagnetic storms.
