Construction Project Status

For the period of performance September 1-30, 2022

(updated December 15, 2022)

Project earned value toward the MREFC effort rose $4.9 million this month to a calculated $463.8 million. The cost variance changed -$0.2 million this month to $1.7 million, and the cost performance index held at 1.0. The schedule variance changed by $.4 million to -$6.7 million, which equates to a schedule performance index of 0.99. Twelve project controls change requests (LCRs) were implemented this month, requesting a total of $1,018,176 from contingency. As of the end of the month, the project has allocated 79% of the total contingency to the baseline through the change control process. The remaining contingency of $17.4 million is 66% of (TPCII  -BAC -CV)/(EACII -ACWP ).

Updated with post Covid replan dates pending agency approval

The table shows forecast dates, i.e., the Project’s current best estimate. There is, in addition, schedule contingency that is not included in those dates, amounting to about 6 weeks at present. It is likely that the Project will use most or all of that schedule contingency. 

The schedule for science data is best estimated relative to the System First Light Milestone. The Operations Team, in consultation with the Rubin Construction Project, currently anticipate the following:

  • The first data preview release (DP1, for details see http://ls.st/rtn-011, which is currently under revision), based on a subset of images supporting the System First Light milestone: 2-3 months after System First Light 
  • The LSST Survey start: 4-7 months after System First Light. Some “near-live” alerts are planned around the time of the LSST Survey start, and then alert production is planned to increase smoothly to "live" during the early months of the LSST Survey, covering more regions over time as the static-sky templates are built up.
  • Data Preview 2 (DP2): 9-12 months after System First Light
  • Data Release 1 (DR1): 12-14 months after LSST Survey start

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 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.
