university of washington explore bhm join us 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 next phase of sdss is currently in its planning phase set to launch in january 2027 more information about as5 and the currently proposed observing programs can be found on the future webpage if your institution would like to be part of sdss now or in future there are a number of incentives to join the project early including a discount for joint membership in sdss v and as5 the general policies for sdss v are defined in its current principles of operation a list of current member institutions can be found on the affiliate institutions page explore data release 20 data
