26 Noviembre 2019: Project & Science News LSST will host a booth and an open house at the American Astronomical Society (AAS) Winter meeting in Honolulu, HI on January 4-9, 2020. The LSST Open House is scheduled for Monday, January 6th from 5:30-7:00 p.m. More details about the LSST booth and the open house will be shared when they are available. The LSST Operations Team recently invited current LSST Corporation Memorandum of Agreement holders to submit Letters of Intent (LOIs) to make in-kind contributions in exchange for LSST data rights. LSST received Letters of Interest (LOI) from prospective international members including 478 principal investigators. About 70 of these are from new institutions without prior agreements with the LSST Corporation. The letters speak to contributions that cover all types of in-kind contributions noted by NSF and DOE in their May 2019 talking points. The letters will be forwarded this week to NSF and DOE …

20 Noviembre 2019: In early November, the GEMMA (Gemini in the Era of Multi-Messenger Astronomy) project brought together science communications professionals to explore the unique opportunities and challenges of communicating Multi-Messenger and Time-Domain Astronomy, two rapidly growing fields in astronomy. Funded by the US National Science Foundation, this communications summit hosted more than 30 participants for two days at the Space Telescope Science Institute (STScI) in Baltimore, Maryland, an AURA-managed facility. Until the mid-20th century, our view of the Universe was limited almost entirely to the narrow band of light that could penetrate the Earth’s atmosphere and was visible either to our eyes or to sensitive photographic plates loaded at the focus of increasingly large telescopes. The first major expansion of our view came with the development of radio astronomy, leading to the realization that the Universe could look very different when seen through different “eyes” tuned to a different type of radiation. …

12 Noviembre 2019: Project & Science News An update on LSST Data Rights and in-kind contributions is now available; read the details at this link. Additionally, a public draft of the LSST Data Policy has been released on Docushare. Questions and comments about the evolving policy are welcome on community.lsst.org. Social unrest in Chile in October had an impact on LSST construction progress, as nightly curfews and safety concerns required the adjustment of work hours and transportation to and from the summit. LSST Project Manager Victor Krabbendam, who was in Chile on a scheduled visit when civil protests began on October 18th, was able to assist with logistics so that dome work could continue on the summit when possible. Photos from his visit are available in the LSST Gallery. Because the social situation in Chile continues to be unstable, we are still monitoring events closely, communicating frequently with personnel in Chile, and planning …

29 Octubre 2019: Project & Science News Our thoughts are with our Chile-based colleagues during the recent period of social instability. All LSST staff and their families, as well as contractors and visitors, are safe, and we have stayed in frequent contact with them since the unrest in Chile began. A team from EIE Group and Phase Motion Control has arrived on the summit to start up and test the LSST Dome azimuth drives. As of last week, the bogies had undergone final alignment, installation/connection of drives was complete, and the dome was successfully rotating under power with a provisional friction drive system in place of the final rack-and-piñon system. A short video of the dome rotating is available at this link. The carousel and back flange of the LSST filter exchange system, which were recently transported by plane from Paris, France, have safely arrived at SLAC National Accelerator Laboratory in Menlo Park, …

15 Octubre 2019: Project Science News On October 1st, the National Science Foundation (NSF) and the Association of Universities for Research in Astronomy (AURA) launched NSF’s National Optical-Infrared Astronomy Research Laboratory (NSF’s NOIR Lab), which integrates operations of all of NSF’s nighttime astronomical facilities. LSST Operations will be one of the five facilities included in this new organization. The LSST Primary/Tertiary Mirror (M1M3) cell assembly has been successfully integrated with the M1M3 mirror surrogate inside the LSST summit facility building. On October 10th, the mirror surrogate was lifted off the cell’s static supports with the system of hard points and pneumatic actuators that will support the weight of the mirror during telescope operations. Many LSST team members in Tucson, La Serena, and Cerro Pachón contributed to this exciting milestone, and photos of the event are available in the LSST Gallery. The filter exchange system for the LSST Camera has left IN2P3 in Paris, …
