SEPTEMBER-OCTOBER2025 Legacy Survey of Space and Time, whichhasthepotentialtoreshape our understanding of the Uni- verse.” The LSST Camera at the heart of Rubin Observatory captures ex- tremely fine features in distant galaxies, stars, and other celestial objects.Ateamofscientists,engi- neers, and technicians at SLAC Na- tional Accelerator Laboratory de- signed and constructed the camera, which is roughly the size of a small carandweighsalmost6200pounds (2800 kilograms). EachimagetakenbytheLSSTCam- eracoversanareaontheskyasbig as 45 full Moons. During its ten-year survey, Rubin willgenerateapproximately20ter- abytes of data per night, plus an additional 15 petabyte catalog database. In 10 years, Rubin data processing will generate around500petabytes,andthefinaldata set will contain billions of objects with trillions of measurements. With regular data releases, scien- tists will be able to conduct their own investigations into Rubin’s data remotely, enabling and expe- diting countless discoveries about ourUniverseandadvancingscience in ways we can’t yet predict. Rubin also brings the power of as- tronomical data and interactive learning to educators and students around the world through an on- linepublicengagementplatform developed by a team of astron- omers, educators, and web design experts, which provides tools and activities to engage and interact with a subset of Rubin Observatory data.
