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.

supportedSurvey design trades depth, area, cadence, angular precision, and wavelength coverage.
Gaia's archive maps Galactic phase space, Kepler established the ubiquity of exoplanets, TESS continues discovering planets and variable sources, and Rubin began LSST operations in June 2026 after its first-look commissioning period.
