Our Mission

Rubin Observatory’s mission is to build a well-understood system that will produce an unprecedented astronomical data set for studies of the deep and dynamic universe, make the data widely accessible to a diverse community of scientists, and engage the public to explore the Universe with us.


LSST received its federal construction start in August of 2014. This website supports the LSST Project Office in its construction of the facility.

Announcement: Director’s Office appointments / Anuncio - Nombramientos en la Oficina del Director

**Versión en Español más abajo**

Dear Colleagues,

Since my appointment as Director of Rubin Construction I’ve been working with the team to set up further appointments in the Director’s office (pending NSF approval). 

For the position of Deputy Director for Rubin Construction for AURA/NSF I am honored to announce Sandrine Thomas. Sandrine is the Rubin Telescope & Site Subsystem Scientist and she brings a wealth of technical and managerial experience from across all facets of the telescope as well as commissioning and program management knowledge. Her experience and can-do approach will be invaluable in getting us across the construction finish line. Over the past few years she has worked tirelessly within the team of the Workplace Culture Advocates, looking for opportunities to improve the  Rubin culture and has contributed immensely to make it a more diverse and inclusive environment.

For the position of Project Scientist for Rubin Construction I am delighted to announce Steve Ritz. Steve is a professor of physics at UC Santa Cruz and is the Rubin Camera Subsystem Scientist. Like many of us, he has been working on implementing positive change in diversity, equity, inclusion, and climate. Before joining us, Steve was the Project Scientist for the Fermi Gamma-ray Space Telescope, so he has ample experience in the many aspects of his new position. In addition, Steve has played a variety of community leadership and advisory roles in astronomy and physics.

Aaron Roodman will take on the role of LSST Camera Program Lead for SLAC/DOE and will be Deputy Director for Rubin Construction for SLAC/DOE. Aaron is a professor of particle physics and astrophysics at SLAC, has been the Camera Integration & Test scientist since 2011 and held a number of different leadership positions at SLAC, KIPAC and in previous experiments.

Please join me in thanking Steve Kahn for bringing us so far, and so close  to success and in congratulating Sandrine, Steve, and Aaron as they step into their new roles.


Estimados colegas,

Desde mi nombramiento como Director de Rubin Construction, he estado trabajando con el equipo para programar mas citas en la oficina del Director (aprobación formal de la NSF pendiente).

Para el puesto de Subdirector de Rubin Construction para AURA / NSF, es un honor anunciar a Sandrine Thomas. Sandrine es la científica del Subsistema de Rubin Telescope and Site y aporta una gran experiencia técnica y de gestión en todas las facetas del telescopio, así como conocimientos sobre puesta en marcha y gestión de programas. Su experiencia y enfoque de poder hacer serán invaluables para lograr la meta del término de construcción. Durante los últimos años, ha trabajado incansablemente dentro del equipo de Defensores de la Cultura en el Lugar de Trabajo, buscando oportunidades para mejorar la cultura Rubin y ha contribuido enormemente a convertirlo en un entorno más diverso e inclusivo.

Para el puesto de Científico de Proyectos de Rubin Construction, me complace anunciar a Steve Ritz. Steve es Profesor de Física en UC Santa Cruz y es el Científico del Subsistema de la Cámara Rubin. Como muchos de nosotros, ha estado trabajando para implementar cambios positivos en diversidad, equidad, inclusión y clima. Antes de unirse a nosotros, Steve fue el científico del Proyecto del Telescopio Espacial de Rayos Gamma Fermi, por lo que tiene una amplia experiencia en los muchos aspectos de su nueva posición. Además, Steve ha desempeñado una variedad de roles de liderazgo y asesoramiento comunitario en astronomía y física.

Aaron Roodman asumirá el cargo de  Líder del Programa de la Cámara LSST para SLAC / DOE y será el Subdirector de Rubin Construction para SLAC / DOE. Aaron es Profesor de Física de partículas y Astrofísica en SLAC, ha sido Científico de Pruebas e Integración de Cámaras desde 2011 y ocupó diferentes puestos de liderazgo en SLAC, KIPAC y en experimentos anteriores.

Únanse  para agradecer a Steve Kahn por llevarnos  tan lejos y tan cerca del éxito y, para felicitar a Sandrine, Steve y Aaron mientras asumen sus nuevos roles.



Financial support for Rubin Observatory comes from the National Science Foundation (NSF) through Cooperative Agreement No. 1258333, the Department of Energy (DOE) Office of Science under Contract No. DE-AC02-76SF00515, and private funding raised by the LSST Corporation. The NSF-funded Rubin Observatory Project Office for construction was established as an operating center under management of the Association of Universities for Research in Astronomy (AURA).  The DOE-funded effort to build the the Rubin Observatory LSST Camera (LSSTCam) is managed by the SLAC National Accelerator Laboratory (SLAC).
The National Science Foundation (NSF) is an independent federal agency created by Congress in 1950 to promote the progress of science. NSF supports basic research and people to create knowledge that transforms the future.
NSF and DOE will continue to support Rubin Observatory in its Operations phase. They will also provide support for scientific research with LSST data.
