Gaia, TESS, Kepler & the Vera C. Rubin Observatory: Observation, Measurement & Evidence

Gaia, Kepler, TESS, and Rubin illustrate four survey strategies: precision astrometry, long-baseline transit photometry, all-sky exoplanet and variability monitoring, and repeated wide-field imaging of the changing sky. These surveys enable Galactic archaeology, exoplanet demographics, stellar astrophysics, transient discovery, Solar-System inventories, and dark-energy studies.
