Project and Science News

Rubin’s 8.4-meter Primary/Tertiary Mirror (M1M3) was successfully coated with protected silver on April 27th, a major milestone for the Project that Rubin announced with a press release including images and timelapse video, and an impactful social media campaign. Read the details about the coating team’s achievement on, and see a fun group photo with the coated mirror in the Gallery.

Reminder to register for the Rubin Community Workshop at SLAC National Accelerator Laboratory in Menlo Park, CA on July 22-26. Payment is required to secure your spot, and in-person registration will be capped at 250 in-person attendees. The room block at the SLAC guest house expires on May 13th — if you’re unable to secure a room there, information about alternate lodging is on the meeting website.

The LSST Camera team at SLAC have been busy preparing to ship the LSST Camera, and all support equipment, to Chile later this month. After SLAC’s official completion announcement in mid-April, the Camera was mounted to a custom shipping frame, wrapped in electrostatic discharge plastic to protect it from moisture, and installed in a 20 ft shipping container (see photos). The Filter Exchange hardware and spare shutter have also been packed in separate crates, and the team is currently working on finalizing logistical details.

A new documentation website,, is now available to help pull together information about the current baseline survey strategy and will contain future reports on survey progress, as well as Survey Cadence Optimization Committee (SCOC) updates. This site also provides links to survey simulations and metric outputs, as well as documentation and tutorials for rubin-sim and rubin-scheduler, software packages useful for creating and evaluating survey simulations.

Data Management (DM), working with the IT Team in Chile, have demonstrated the ability to run pipelines on the commissioning computing cluster (yagan) on Cerro Pachón. Rubin's active optics system (AOS) team ran their wavefront estimation code on simulated ComCam data, displaying the results for the summit observing team using RubinTV. As soon as the project begins taking images with ComCam, the highest priority will be to align the optics (the M1M3 mirror, the M2 mirror, and the camera). The ability to rapidly analyze and visualize the data will enable informed decisions about how to tune the system.

Operations Updates: 

The South/America Africa Astronomy Coordination Committee (SA3CC) met at SLAC last week for its annual meeting. The meeting is organized by AmLight, the research and education network (REN) project run by Florida International University through a cooperative agreement with the NSF. AmLight is the project through which Rubin secures its guaranteed bandwidth for the long haul network (LHN) from Chile to Atlanta. The Rubin Operations Director, Deputy, and members of the US Data Facility and DevOps teams participated. Participants heard about the excellent status of Rubin Project, Operations, networking, and multi-site processing. Other talks covered progress at high altitude experiments in Chile investigating the early universe via the Cosmic Microwave Background. The SA3CC meeting was followed by the Rubin NET meeting, a technical meeting concentrating on the details of Rubin’s LHN and its performance.

The Rubin/Euclid DDP Implementation Group has extended the deadline (to May 8th) for this community survey in order to seek out and identify individuals and/or research groups who are interested in investing significant effort in the creation of Rubin-Euclid Derived Data Products (DDP) that will be widely distributed within the astronomical community.

Personnel Announcements & Opportunities:

Dan Fuchs joined Rubin Data Management’s SQuaRE (Service Quality and Reliability Engineering) team as a senior devops engineer on April 29th. Based remotely as an employee of SLAC, Dan will be working on the infrastructure that underpins the Rubin Science Platform and other SQuaRE services.
