LSST PRIMARY/TERTIARY MIRROR (M1M3) ARRIVES ON CERRO PACHÓN

May 11, 2019 – This morning, a unique astronomical mirror reached its new home in the Andes Mountains of Northern Chile. This incredible mirror will enable the Large Synoptic Survey Telescope (LSST) to catalog an estimated ~40 billion celestial objects—more objects than there are humans on earth. LSST will scan the entire visible sky every few nights, visiting each location approximately ~1000 times during its ten-year survey, which is scheduled to begin in 2022. With these fast, repeated observations LSST will open a new window to the changing Universe, providing countless new opportunities to do science with transient objects such as asteroids and supernovae. Additionally, with the wide field of view made possible by this mirror, LSST will advance the study of dark matter and dark energy.

LSST is jointly funded by the National Science Foundation (NSF) and the United States Department of Energy (DOE), but the fabrication of the M1M3 began in 2008 thanks to private donations, though the LSST Corporation primarily from Charles and Lisa Simonyi and Bill Gates, before the Association of Universities for Research in Astronomy (AURA) was awarded LSST Construction funding.

The 8.4-meter LSST Primary/Tertiary Mirror (M1M3), one of the largest and most recognizable elements of the telescope, is unusual because it consists of two mirror surfaces combined on one large substrate. Light from the sky will hit the outer ring (M1) first, reflect upwards to a separate second mirror (M2), and then bounce back down to the inner ring (M3) of the monolith before reaching the telescope. LSST's three-mirror design, combined with a highly sensitive camera, allows the telescope to collect light from faint objects over a very large field of view. Combining the M1 and M3 mirrors gives the telescope a more compact shape, which enables it to move (slew) quickly between points on the sky and to settle efficiently before taking its next image.

The M1M3 safely arrived at the LSST summit facility building on Cerro Pachón in Chile on May 11, 2019. Its eight-week journey began on March 15, in Tucson, Arizona, USA, where it was fabricated. The M1M3 was the first LSST component to be completed, and the mirror will play a critical role in enabling countless scientific discoveries. Constanza Araujo, former LSST Telescope and Site Senior Optics Lead offers an analogy to illustrate the importance of this milestone: “The primary mirror is the heart of any telescope, and so the M1M3 is the heart of LSST.”

Combining two astronomical mirrors with different curvatures into one surface had not been done before, but it is this unique design that will enable LSST to combine speed with a crisp, wide field of view. According to LSST Chief Scientist Dr. Tony Tyson, “Combining the primary and tertiary mirrors into two mirrors fabricated on the same Pyrex blank creates a 10-square-degree field of view with very low distortion. This enables an unprecedented broad science reach from cosmology to the time domain—all with a single, comprehensive sky survey.”

The M1M3 was fabricated over a period of approximately seven years at the Richard F. Caris Mirror Lab at the University of Arizona. The "High Fire" event, in which the glass was cast, took place in March 2008, and the mirror was completed in April 2015 after years of grinding and polishing brought the surfaces to the required specifications. The M1M3 was then lifted into a custom shipping crate and put into storage while its support hardware was constructed; both the shipping container and the support structure for the M1M3 were constructed by CAID Industries in Tucson. In October 2018 the mirror returned to the Mirror Lab to be integrated with its support hardware and to undergo further optical testing, which concluded successfully in March 2019.

Transporting the mirror from Tucson, AZ to Cerro Pachón required specialized equipment and a lot of planning—the mirror in its shipping container weighs approximately 110,000 lbs (50 metric tons) and measures about 30 feet (9.14 meters) in diameter. A transport vehicle operated by Precision Heavy Haul, Inc. carried the M1M3 from Tucson to the shipping port in Houston along a carefully planned route. The M1M3 container was then loaded aboard the BBC Manitoba for a four-week ocean voyage to Coquimbo, Chile, via the Panama Canal. From the port at Coquimbo, the M1M3 was loaded onto an impressive 72-wheeled transport vehicle, operated by Javier Cortés, bound for the LSST summit facility on Cerro Pachón. This final leg of the journey required cooperation between many parties to coordinate logistics, including the removal of hanging signs, utility cables, and lights along the route. Local police provided an escort for the transport vehicles, and various administrative organizations assisted with road closures and permits to proceed.

At approximately 2:00 a.m. on May 10th, the vehicle carrying the mirror passed through the tunnel at the Puclaro Dam—the narrowest spot on the route. With just inches to spare on either side, the mirror passed through without incident.

Now that the mirror has arrived on the summit, it will be stored for a period of time while other components of the telescope arrive from their places of manufacture around the world.

May 3, 2019 - CC-IN2P3 is one of the computing facilities that will be responsible for processing and storing data collected by LSST during Operations. The campaign to upgrade the center’s power and cooling infrastructure in preparation to host LSST data has entered its final phase. Located in Lyon, France, CC-IN2P3 has two computer rooms of 850 m2 each (9,150 ft2) hosting about 18,000 CPU cores, 28 PB of disk storage, and four automated tape libraries where 63 PB of data are stored. These resources are routinely used by several scientific projects, 24/7.

The most recent computer room is designed to be equipped as the need for more computing equipment arises, without disrupting operations. A new chilled water production line and a Tier-III power and water distribution system have been installed to allow for the deployment of two additional hot corridors. More than 120 tons of equipment sit now on the roof of the building, providing the cooling infrastructure the computing equipment requires.

When this upgrade is completed this spring, 80 additional racks of equipment will be progressively installed to satisfy the needs of major world-class scientific projects including LSST, which at its peak will require 35 racks of equipment at CC-IN2P3.

By 2022, the CC-IN2P3 will have deployed a storage capacity of more than 20 PB devoted to LSST data and a computing platform composed of about 22,000 CPU cores ready to contribute to processing the data coming out of the telescope. With its project partners, CC-IN2P3 is currently prototyping and evaluating technical solutions for transporting, storing, cataloguing and processing large amounts of data at the scale needed by LSST.

Please mark your calendars: The LSST 2019 Project and Community Workshop will take place August 12-16 at the Hilton El Conquistador in Tucson, AZ. More details will be provided as they are available.

The LSST Primary/Tertiary Mirror (M1M3), aboard the BBC Manitoba, is rapidly making its way south to Chile. The ship passed through the Panama Canal on April 15, and after a few stops at ports along the way, it is scheduled to arrive in Coquimbo, Chile, in May. See the ship’s most recent location at this link.

The M1M3 cell will soon be following the mirror to Chile; it was wrapped for shipping at vendor CAID Industries in Tucson last week and then loaded onto the 120-foot-long vehicle that will transport it to Houston, Texas. Photos of the cell being loaded on April 18th are available in the LSST Gallery.

The final test campaign for the vertical platform lift designed and fabricated by PFlow industries, which will be used to move heavy LSST components between floors of the LSST summit facility building, was completed last week. The lift was loaded with barrels containing approximately 18,500 gallons (70,000 liters) of water. With the weight of the tanks themselves and the detachable lift-up roof, the lift successfully raised about 94 tons (85,650 kg) of weight, which simulates the maximum payload of the M1M3 mirror and cell in its cart. A video of the lift in action during the tests is available in the LSST Gallery.

The LSST Data Management team held a Final Design Review of the LSST Science Platform (LSP) on April 10-12. This was a formal and internal review of the planned LSP capabilities during LSST Operations. The panel consisted of eight LSST stakeholders drawn from both the LSST project and science collaborations, and one external expert in the field, who were asked to provide an evaluation of the vision, design, and current implementation status against the LSST science requirements. Overall the feedback was very positive. The panel provided a closeout briefing of their preliminary findings, outlining their recommendations, questions, and concerns. A full and final report will be delivered two weeks from the close of the review. A group photo from the event is available in the LSST Gallery.

LSST staff in Chile hosted a visit from AURA leadership on April 16-17. AURA President Matt Mountain toured the LSST base facility; and Val Schnader, Vice President for Operations/Chief of Staff toured the LSST summit facility. The visit was an opportunity for AURA leadership to view LSST construction progress.

PROJECT & SCIENCE NEWS - NOTICIAS DEL PROYECTO Y CIENTIFICAS

The updated LSST overview paper, “LSST: From Science Drivers to Reference Design and Anticipated Data Products” was published in the March 11, 2019 issue of The Astrophysical Journal. The paper can be accessed at this link.

Over the last few months, the LSST Scientific Advisory Committee (SAC) has been carefully examining and considering the submitted White Papers on LSST Cadence Optimization, as have Project members. While the SAC is still deliberating and looking into a few specific questions, its report should be available and made public in April.

The LSST Primary/Tertiary Mirror (M1M3) arrived successfully in Houston, Texas, on March 21st after leaving the Richard F. Caris Mirror Lab in Tucson, Arizona, on March 15th. The mirror is scheduled to ship to Chile from the Port of Houston within a few days, and will take approximately five weeks to reach Coquimbo. Details about the mirror’s departure from Tucson can be found in this recent news post, and photos of the M1M3 along the route to Houston are available in the LSST Gallery.

At SLAC National Accelerator Laboratory, two of the six cryogenics circuits comprising the LSST Camera cryo system were recently turned on and temperatures of approximately -130C were achieved on the cryoplate, as designed. This is a tremendous milestone for the Camera and demonstrates early integration of the cryostat, vacuum system and partial refrigeration system.

Assembly and verification of the LSST Coating Plant continues at the LSST summit facility. The team from Von Ardenne recently completed the first sputtering deposition using all of the magnetrons. The magnetron sputtering system will allow depositions with protected silver, bare aluminum, or protected aluminum on either the Primary/Tertiary Mirror (M1M3) or the Secondary Mirror (M2). This important technical milestone demonstrates the successful functioning of both the sputtering system—the heart of the coating chamber—and the vacuum system, which supports the sputtering process. Photos of the ongoing Coating Plant work are available in the LSST Gallery.

INFORMATION FOR PROJECT MEMBERS

Below is the third in our ongoing series of reminders about individual communication channels used within the LSST Project. Information about all LSST communication channels can be found in Document-28656.

The current featured channel is Slack, an LSST Corporation-operated instant messaging application intended for quick conversations. This tool is especially powerful for group discussion. It includes all LSST Science Collaboration members, so “open” Slack channels may not be used for sensitive project information. In general, tasks assigned and decisions made in Slack discussions must be documented elsewhere. It should not be assumed that if someone has a Slack account that they are actively using it. The Project office uses Slack as one of multiple channels of communication; announcements posted on Slack will be repeated elsewhere.

El canal destacado actual es Slack, una aplicación de mensajería instantánea operada por la Corporación de LSST para conversaciones rápidas. Esta herramienta es especialmente poderosa para la discusión grupal. Incluye a todos los miembros de la Colaboración Científica de LSST, por lo que los canales Slack "abiertos" no se pueden usar para información confidencial del proyecto. En general, las tareas asignadas y las decisiones tomadas en las discusiones de Slack deben documentarse en otra parte. No se debe asumir que si alguien tiene una cuenta de Slack, la está utilizando activamente. La oficina del proyecto usa Slack como uno de los múltiples canales de comunicación; los anuncios publicados en Slack se repetirán en otros lugares.

March 26, 2019 - UPDATE: The M1M3 has arrived in Houston and is now waiting for the ship that will take it to Chile. The trip from Tucson to Houston was uneventful for the mirror, but sparked a lot of curiosity from motorists who had to make way for this very oversized load! More photos, provided by transport company Precision Heavy Haul, Inc., are available in the LSST Gallery.

March 15, 2019 - LSST’s biggest mirror, the 8.4-meter Primary/Tertiary Mirror (M1M3), is officially on its way to Chile! Before dawn this morning, the vehicle carrying the mirror in its storage and transport container departed from the Richard F. Caris Mirror Lab in Tucson, AZ. On Tuesday the mirror was loaded into the container using a custom lifting fixture, and on Thursday the container was loaded and secured onto a 108-foot Precision Heavy Haul, Inc. vehicle outside the Mirror Lab in preparation for this morning’s departure. Now, the mirror is on its way to the Port of Houston in Texas, where it will be loaded onto an assigned ship for its five-week ocean voyage to Chile.

The transport vehicle, with its wide and fragile load, will travel slowly on a route designed to minimize traffic disruption. While on a typical road trip it might take two days (driving about eight hours per day) to make the trip from Tucson to Houston, we anticipate that this leg of the journey will take the vehicle carrying the M1M3 approximately 10 days.

Tucker Booth, LSST Telescope and Site Mechanical Engineer, supervised the departure of the M1M3 this morning. As the truck was pulling away from the Mirror Lab, Booth remarked, “A lot of people worked very hard to get to this moment. It’s exciting to have the work in Tucson finished, and to move on to the next phase.”

Photos of the M1M3 being loaded are available in the LSST Gallery.
