| Abstract: |
The Decadal Survey on Astronomy and Astrophysics 2020 highlights the importance of advancing
research focused on discovering and characterizing habitable worlds. In line with this priority, our goal is to
investigate how planetary systems evolve through atmospheric escape and to develop methods for identifying
potentially Earth-like planets. By leveraging the ultraviolet (UV) capabilities of the Habitable Worlds
Observatory, we can use transit spectroscopy to observe atmospheric escape in exoplanets and explore the
processes that shape their evolution, assess the ability of small planets to retain their atmospheres, and search
for signs of Earth-like atmospheres. To achieve this, we support the development of a UV spectrograph with
moderate- to high-resolution capabilities for point-source observations, coverage of key spectral features in
the 1000-3000˚ A range, and detectors that can register high count rates reliably.
