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.
Structure
Structure of Gaia, TESS, Kepler & the Vera C. Rubin Observatory
Gaia measured positions, parallaxes, proper motions, and spectra for a vast stellar catalog. Kepler stared deeply at selected fields for precise transits, TESS surveys large sky sectors around bright nearby stars, and Rubin repeatedly images the southern sky with a 3.2-gigapixel camera.
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.
