Overview
Advanced view of 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.
These surveys enable Galactic archaeology, exoplanet demographics, stellar astrophysics, transient discovery, Solar-System inventories, and dark-energy studies.
Chapter review
Assessment still in review.
The chapter is published, but its assessment has not completed the verification and QA pipeline yet. It will appear here after publication.
