NASA’s upcoming mission aims to explore an elusive part of our atmosphere known as the geocorona, a faint halo of hydrogen gas that extends thousands of kilometers beyond Earth’s atmosphere. Despite its vast size, this atmospheric layer remains invisible to the naked eye and poorly understood by scientists. Utilizing cutting-edge ultraviolet sensors aboard a specialized satellite, the mission will map the geocorona’s structure and dynamics with unprecedented detail, shedding light on how it interacts with solar radiation and Earth’s magnetic field.

The mission’s goals include:

  • Measuring hydrogen density: To learn how this halo affects satellite drag and space weather.
  • Tracking temporal changes: Observing how the geocorona fluctuates with the solar cycle.
  • Improving atmospheric models: Enhancing predictions related to low Earth orbit conditions.

Early data will be critical for protecting future space missions and advancing our understanding of atmospheric escape processes that shape planetary environments.
