The sequence below comes from this topic's published material. Sections expand or contract with the subject instead of forcing every lesson into the same five-step mold.
Overview
Core model: Gaia, TESS, Kepler & the Vera C. Rubin Observatory
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. As of 2026, Gaia and Kepler have ended spacecraft operations, TESS remains active, and Rubin's 10-year Legacy Survey of Space and Time has begun.
