May 4, 2018 - An LSST team spent 5 days in Spain last month conducting a thorough safety review of the Telescope Mount Assembly (TMA) at the facility of vendor Asturfeito. LSST Safety Manager Chuck Gessner, Telescope and Site Technical Manager Shawn Callahan, Senior Systems Engineer Austin Roberts, and Lead Electrical Engineer Oliver Wiecha inspected the numerous safety features included in the TMA, and reviewed the procedures by which the group of vendors responsible for building the TMA (referred to as UTE) will verify that the hazard mitigations meet LSST requirements. The team determined that although there are still actions that must be completed by the vendors before the TMA ships to Chile (currently scheduled for November 2018), everything is on track to be finished in time. At the conclusion of the review, Asturfeito and designer Empresarios Agrupados (EA) were given approval to begin Factory Acceptance Testing for the TMA.

“Back in the early design days,” says Chuck Gessner, “we used Military Standard 882 and our own personal experience working on large telescopes to help us identify and document potential hazards.” The process became an official LSST policy (LSST Hazard Analysis, or LPM-49) and was included in the design documents presented to the vendors for the TMA. The corrective measures or mitigations that were also identified to eliminate or minimize the hazards were written into the LSST/vendor contracts. Each mitigation or safety feature built into the TMA will be evaluated separately by documented test procedures during the Factory Acceptance Tests to ensure not just that it has been built, but also that it functions as intended to prevent accidents or injuries before shipment to Chile. The recent review was significant because it marked the first time many of these longstanding design elements could be inspected as physical parts of the telescope.

The TMA presents numerous safety challenges for individuals working on and around it, many of them related to the massive size of the structure. The elevation drive, for example, which will eventually move on a pre-programmed cadence, weighs approximately 151 tons. It’s critical from a safety perspective that this structure can be locked in place when people are working around the telescope. Therefore, it has giant dedicated stay-pins that can be set in place to prevent unexpected movement of the drive.

In Chile, workers will regularly need to access parts of the telescope that are far off the ground, so the TMA also includes features that allow them to do this safely. A versatile articulating boom lift (shown in the photo above) can be maneuvered into position to allow an individual to access the center section of the telescope while safely harnessed to the secure lift basket. Additionally, although not yet installed, a set of deployable platforms will be situated on top of the fixed platforms on the side of the TMA structure. These platforms can be moved towards the camera, providing stable structures for workers (who will also be wearing fall protection gear) to stand on while accessing the camera to change filters or perform maintenance on it.

The silent azimuth and elevation linear drives will operate using magnet assemblies (shown in the photo on the left below) that have been installed on the drive arcs, and the DC power to run the motors will be supplied by large capacitor banks. Mitigations related to the hazards of these capacitor banks were also inspected during the safety review; for example, the capacitor cabinets (the orange boxes in the photo below) are designed with an interlock that prevents the doors from being opened when the voltage inside the cabinets is unsafe.

These are just a few of the 149 mitigations or precautions LSST and designer EA have taken to make sure people are safe working on and around the TMA. During the Factory Acceptance Testing in the coming months all of the mitigations will be tested and verified. And in Chile, where the TMA will arrive late this year, the team of LSST safety personnel and engineers is growing as integration activities increase.

April 26, 2018 – An LSST cross-project team met at the National Center for Supercomputing Applications (NCSA) earlier this month to conduct the latest in a series of Early Integration Pathfinder Activities. This activity focused on simulated control and image collection for the nominal Auxiliary Telescope visit sequence. The exercise was the culmination of intense effort from a distributed group of LSST project members, and it offered the opportunity for participants representing different subsystems to align expectations, resolve issues, and determine priorities for next steps.

The goal of this Pathfinder activity was to exercise the Auxiliary Telescope (AT) software subsystems in performing sequences related to the operation of the AT, including startup and shutdown of all subsystems, commanding telescope movements, and the creation of images with the Auxiliary Camera. Although many of these sequences had been successfully run prior to this activity, an entirely new set of APIs, specific to the Auxiliary Telescope and Camera, were developed in the weeks leading up to the event. An additional sequence for producing and archiving images as FITS files was also tested for the first time. This sequence will be very similar to the one used by the main LSST Camera, so the progress made during this exercise will be extremely useful in the future.

The equipment used in this activity was the NCSA L1 Test Stand, which provides an environment in which software can be tested in the absence of the actual telescope and camera hardware. The activity at NCSA was a software-only test, but as hardware components of the Auxiliary Telescope become available, they will be integrated into the test process. Therefore, as the activities progress, the testing environment will increasingly resemble the actual environment on Cerro Pachón during operations.

The next Pathfinder activities are scheduled to occur in May and June in Tucson, and will be focused on getting real pieces of the Auxiliary Telescope hardware, including the spectrograph, working with the same APIs that were tested at NCSA. A full-sized photo of the participants present at NCSA is available in the LSST Gallery, and the complete list of participants, including those who participated remotely, is below.

Wednesday, April 11, 2018

April 11, 2018 - The LSST Network Engineering Team is pleased to announce the first successful transfer of digital data over LSST/AURA 100 gigabit per second fiber optic networks from the Summit Site on Cerro Pachón, Chile to the Base Site in La Serena, Chile and on to the Archive Site at NCSA in Champaign, IL. This event took place in December 2017 and demonstrated not only performance and continuity across all hardware segments of the network, but a well-coordinated effort by multiple international engineering teams in support of LSST.

This challenge, driven by the "astronomical" needs of LSST to transport data from Cerro Pachón to NCSA for processing, and to distribute data from Cerro Pachón to the rest of Chile and the world, was the motivation for this international collaboration. AURA coordinated the project in conjunction with REUNAin Chile, and in the United States with FIU/AmLightand NCSA. At the international level, the joint work with FIU/AmLight demonstrated transcontinental infrastructures that ensure the data flow to the United States is coherent and reliable.

This scientific and technological milestone marks the first stage of a project at the Chilean national level, which is part of REUNA's 2018-2021 Strategic Plan that will provide a platform for the collaborative development of science and education, suitable for transmission and analysis of real time data obtained from the Universe. It will have an impact on multiple research areas, such as computer science, mathematics, physics, and others, enabling them in the new era of Big Data Science.

In Chile, the 800 km network between Cerro Pachón, La Serena, and Santiago has an initial capacity of 10Tbps (96 optical channels of 100Gbps each) with an "unlimited" potential growth bound to technology development. For example, there are already prototypes of 400 Gbps channels, which would quadruple the capacity.

In the first data transfer carried on this new network, a set of 6 x 10 Gbps network interface cards in data transfer nodes (DTN) configured with iPerf3 software generated a sustained data rate of approximately 48 gigabits per second, during a 24-hour period. This exceeded the test objective of 40 gigabits per second.

It should be noted that this project began on December 5th, 2014, with the public announcement by AURA, REUNA, and Telefónica of the implementation of the digital infrastructure between Santiago and Cerro Pachón. The Chilean Ministry of Economy supported the announcement.

Currently, professionals from AURA (Chile and the USA), REUNA (Chile), Florida International University (USA), AmLight (USA), RNP (Brazil), and UI NCSA (USA) participate in the LSST Network Engineering Team (NET), which provides the means to engineer end-to-end network performance across multiple network domains and providers.

It is also important to mention the role played by private companies in the development of these infrastructures.  In the case of Chile, Telefónica has been a strategic partner with a vision of collaboration with the National Academic Network in the technological development of the country. In the case of the USA, Internet2 and Florida LambdaRail have been long-term collaborators, supporting FIU/AmLight and the astronomy community in Chile.

April 4, 2018 - With the completion of two additional 100Gbps “points of presence,” LSST now has a redundant, high-speed, fiber-optic network between Santiago, Chile, and Miami, Florida. This is the international portion of the network for transferring data from the summit of Cerro Pachón to the National Center for Supercomputing Applications (NCSA) at the University of Illinois, some 8000 kilometers (nearly 5000 miles) away. The additional connectivity in Santiago, Chile, and Fortaleza, Brazil, was installed in late February and early March, 2018, and completed the ring shown in yellow in the accompanying figure. Jeffrey Kantor, of the LSST Project Management Office, said, “This development will enable LSST to realize a reliable, high-speed network connecting LSST sites in Chile and the United States. This network will permit LSST data to travel in seconds to our LSST Data Facility at NCSA where it will be processed into scientific data products including real-time alerts of transient events, calibrated images, and catalogs ultimately containing billions of galaxies and stars.” The network links are provided as part of the NSF IRNC: Backbone AmLight Express and Protect (ExP) project and the AmLight Consortium: a group of not-for-profit universities, state, national, and regional research and education networks including the AmLight ExP project at Florida International University, AURA, LSST, RNP, ANSP, Clara, REUNA, FLR, AURA, Telecom Italia Sparkle, Internet2.

March 23, 2018 - After three years of construction work on Cerro Pachón, general contractor Besalco Construcciones achieved substantial completion of the LSST Summit Facility on February 28, 2018. On that date, the building keys were officially turned over to LSST Construction Inspector Jaime Seriche and LSST Site Manager Eduardo Serrano. Although 20-30 Besalco workers will remain on-site for a few more weeks, addressing punch list tasks, LSST now has authority over the occupation of the facility and the site work schedule. Current activity in the building includes IT equipment installation, furnishing of offices, and post-construction projects for various LSST subsystems.

According to Telescope & Site Architect Jeff Barr, It's worth noting that despite the inevitable challenges, delays, and changes that occurred during the three years of construction, "the contract between LSST and Besalco is concluding on successful terms." Jeff anticipates that the punch list items will be complete and final acceptance of the building will occur in April.

March 9, 2018 - Exciting progress took place in February at subcontractor Asturfeito in Spain, where personnel assigned to the Telescope Mount Assembly (TMA) engaged in balancing and metrology activities.

Although LSST’s telescope will eventually be controlled by computers, current balancing activities require a manual approach in which the telescope, while floating on oil, is moved by winches. Measurements of the force on the telescope are taken to ensure the telescope is balanced whenever it’s off-zenith. This video, taken during the balancing of the elevation structure, illustrates the process.

The LSST Camera and glass mirrors won’t be integrated with the TMA until it arrives on Cerro Pachón and undergoes extensive testing there, so steel surrogates (painted yellow) are being used to simulate the mass of those components in the factory. According to LSST TMA Technical Manager Shawn Callahan, “With the surrogates installed, and the telescope balanced, you could theoretically move the entire structure with your hand.”

The Asturfeito team is also using a laser tracker, mounted on the Primary/Tertiary Mirror (M1M3) surrogate, to carefully measure the locations of the critical optical interfaces, ensuring all the surfaces are exactly where they need to be for successful integration of the Camera and mirrors.

This month, subcontractors from all over Europe are meeting at Asturfeito to install the support equipment necessary to move the telescope under computer control, which is currently scheduled to take place at the end of March.

February 27, 2018 - In calendar year 2018, almost $100M of equipment will be transported to Cerro Pachón from the U.S. and around the world for integration into the LSST summit facility building. Major items include the Telescope Mount Assembly (TMA), the Coating Chamber, the Dome, the Primary/Tertiary Mirror (M1M3) and Secondary Mirror (M2), the mirror cells, and the hexapod rotator (with its twin spare). These items will be gathered from several locations, including Rochester, NY; Tucson, AZ; Denver, CO; Italy, Spain, and Germany, and shipped to the Chilean port of Coquimbo for ground transport to the summit. The designer of much of the complex, but flexible, logistics program is LSST Principal Surveyor Michael Logue.

Michael joined the project in May of 2017 with over 30 years of broad cargo and freight management experience including hands-on project cargo supervision. He is assisting the Telescope and Site team by developing a logistical plan and overseeing its execution for the timely and safe delivery of all critical components.  Compared to many other projects Michael has been involved with, LSST involves “diverse logistical challenges with unique goals and, ultimately, bold positive outcomes.” The LSST summit webcam and current images in the Gallery show construction progress; currently trusses for the dome are being delivered in large shipping containers from Italy and their installation has begun.

Although shipping logistics and timetables are still being finalized, at this point we anticipate the TMA, Coating Chamber, and the Mirrors, Cells, and Surrogates will travel together on chartered specialized heavy lift cargo ships. Other components will be shipped in about 70 x 40’ shipping containers as orchestrated by the selected forwarding company Kuehne + Nagel. Our contracted shipping company, BBC Chartering, will have a cargo ship stop in Antwerp, Belgium or Hamburg, Germany for the Coating Chamber and Washing Station, then travel on to the port of Aviles in Spain to pick up the TMA, and then proceed onward to Chile. In parallel, one ship will depart Houston with components previously shipped by ground (from CO and AZ) by Precision Heavy Haul to that port. The M2 is likely to be transported to Albany, NY, for travel down the Hudson directly to Chile. The Auxiliary Telescope will be transported by container from Tucson, via Houston to Chile in early March.

After getting everything to the Chilean port of Coquimbo, it will take over 100 individual trips to the summit with truckloads full of components in conjunction with our heavy hauler, Javier Cortes. Pieces will be stored on AURA property just below the summit and then brought up in a timely sequence as integration proceeds. Once all the components are on the summit, the existing logistical situation on the top, already a shell game of relocating pieces awaiting installation to make room for others, will become even more complex exercise involving over 6000 freight tons as LSST integration continues to move forward. 

This is an extremely complex period of activity for LSST, putting the pieces together to build this unique facility. Stay tuned for updates over the next year as we stay on track for full occupancy of the summit facility by year’s end.

Led by LSST Education Specialist Ardis Herrold, the event gathered 11 high school and college educators from across the U.S. to solicit feedback on prototypes of the online educator tools, including Jupyter Notebook-based interactive astronomy investigations, currently being developed by the EPO team. Opinions provided by the participants will help guide future stages of EPO product development, ensuring the continued alignment of EPO products with educator needs.

Over the course of the two-day focus group meeting teachers were introduced to the suite of online tools that will be available through EPO’s Education Hub. The Education Hub, a section of the larger EPO Portal, will house resources specific to educators such as national education standards alignment and assessment guides, information about professional development opportunities, and classroom investigations featuring real LSST Data in Jupyter Notebooks.

“This meeting was important,” reflected Ardis, “because it was the first time anyone other than our team has looked at what we’re developing. Although we anticipated there would be some confusion with the notebooks, we were pleasantly surprised at how easily the teachers figured out how to work with them.”

Throughout each day, teachers filled out detailed questionnaires created by EPO Evaluation Specialist Ellen Bechtol in order to capture their reactions to the material presented. “The central question of whether they would use these tools in their classroom,” says Ellen, “was answered by this group with a strong ‘yes.’” All of the feedback from this focus group will help the EPO team prioritize product features so that time and resources are spent on those most useful to educators.

The teachers who participated in this focus group meeting were carefully selected by the EPO team for their expertise in both astronomy and education. The fact that they were enthusiastic about the direction of LSST’s EPO products is encouraging, but it’s only one piece of the puzzle; once the EPO team has had the chance to refine the notebooks a bit further, they will seek opinions from a group that represents a more typical population of educators. That focus group is currently scheduled for July 16-18. In the meantime, Ardis hopes to conduct an informal event for local educators and/or astronomy students. “If we can test reactions to some of the individual components ahead of time,” she says, “We can refine the way we will present them to the teachers in July in order to get the quality feedback we need.”
