SDSS is operated by an international collaboration of hundreds of scientists at numerous institutions around the globe. The scientific achievements of  SDSS are enabled by the technical capabilities, financial contributions, and above all, the collective scientific expertise and enthusiasm of this vibrant collaboration.

The active operational phase of the project is SDSS-V, which began collecting data in October 2020 and is expected to run through 2025. SDSS-V operates at Apache Point Observatory in the USA and at Las Campanas Observatory in Chile. The first data release is anticipated to be in 2022.

The SDSS-V collaboration continues to seek new institutional partners. Policies for joining SDSS-V can be found in the SDSS-V Joining Document.

The SDSS-V collaboration’s governing body is its Advisory Council (AC), which formulates recommendations on project scope and budget to the Board of Governors of the Astrophysical Research Consortium (ARC). Critical decisions about the scientific objectives, hardware and software builds, and day-to-day operations are managed by the Central Project Office (CPO) and/or the Management Committee (MC), which includes the CPO along with the leaders of the Mappers, the instrument groups, and other infrastructure teams.

Collaboration policies that address publications and data access are developed and implemented by the SDSS-V Collaboration Council (CoCo), which has a representative from all of the full and associate institutional partners. The CoCo is chaired by the SDSS Spokesperson, who is elected by the collaboration for a 3-year term.

For more detailed information about how the SDSS collaboration operates, please see the policy documents below.


The top-level governing policy for SDSS-V is its Principles of Operation, which is descended from the Principles of Operation documents of previous SDSS generations. This document describes the scientific objectives, management structure, and basic operational policies for the survey.

The Publication Policy describes how projects and papers using survey data are announced to the collaboration, how different types of publications are classified, and how to give credit to individuals for analysis and infrastructure work. The Publication Policy is developed and implemented by the CoCo, and approved by the AC.

The External Collaborator (EC) Policy describes the limited circumstances and procedures under which pre-release SDSS-V data can be shared outside the collaboration. The EC Policy is also developed and implemented by the CoCo, after approval from the AC.

SDSS-V has adopted a Code of Conduct as part of its commitment to providing a healthy, inclusive working environment for all of our members, regardless of identity or career stage. All collaboration members are expected to abide by these guidelines in all interactions with their colleagues, including over email and during in-person or virtual meetings.
