SDSS-V is the first facility providing multi-epoch optical & IR spectroscopy across the entire sky, as well as offering contiguous integral-field spectroscopic coverage of the Milky Way and Local Volume galaxies. This panoptic spectroscopic survey continues the strong SDSS legacy of innovative data and collaboration infrastructure.
NEW: Our latest data release, DR19, is now live!
Data
Our latest data release, DR19 is now live! This is the first big data release for SDSS-V and contains spectra and data products from Black Hole Mapper and Milky Way Mapper, as well as a preview tile of the Helix Nebula from Local Volume Mapper. We are also releasing new Value Added Catalogs, tutorials that show you how to work with the DR19 data, and our new visualisation webapp, Zora. Find out more about DR19 on the DR19 webpages, and in the DR19 paper.
If you are looking for previous data releases from SDSS-IV, then these are all still available! You can find them on our completed surveys page, and at the SDSS-IV webpages. Completed surveys include the SDSS Imaging and Legacy Survey, Supernova Survey, SEGUE1/2, MARVELS, (e)BOSS, APOGEE-1/2, MaNGA and MaStar.
Our next data release will be DR20, and is currently scheduled for 2026.

SDSS-V, like previous SDSS surveys, remains committed to making its data publicly available in a format that is helpful to a broad range of users, from beginner students to both amateur and professional astronomers. However, without extensive federal or other large-scale funding, this commitment is not possible to fulfill without membership contributions from institutional partners. SDSS-V is actively seeking participation from new membership partners. Our institutional partners benefit from early access to proprietary data, participation in the survey planning process, and involvement of their faculty, postdocs, and students in our global science collaborative network.
Policies for joining SDSS-V at a variety of levels can be found in the Joining Document. The general policies for SDSS-V are defined in its current Principles of Operation.
