As illustrated in the accompanying graphic, the different roles of the LSST Project Office (LSSTPO) and LSST Corporation (LSSTC) have been clarified to align with the responsibilities and limitations of our federal construction funding. The Project Office has stepped out as a true construction project, responsible for Building the Future: the LSST observing facility. In contrast, the Corporation will focus its efforts on Preparing for Science, fundraising, and defining partnerships and plans for Operations. This distinction will become more clear in the coming months with the transfer of the M1M3 mirror from LSSTC to LSSTPO and emerging support from LSSTC for the science collaborations. The LSST Project Office will remain focused on the construction of the LSST facility as detailed in the baseline plan presented to the NSF and DOE federal funding agencies.
