The LSST secondary mirror (M2) system has completed another big milestone, with successful demonstration of closed-loop mirror control. The Harris team accomplished this using the aluminum surrogate mirror integrated into the cell assembly.  Meanwhile, the mirror substrate is being prepared for its “first light optical test” in July at Harris in Rochester, NY, with the successful bonding of all actuator pads.

April 28, 2017 - The third session of the LSSTC Data Science Fellowship Program(DSFP), hosted jointly by NOAO and the University of Arizona, took place this week in Tucson. The Data Science Fellowship Program is a two-year training program supported primarily by the LSST Corporationthrough its Enabling Science Initiative, with additional contributions from Northwestern University. The program is designed to teach astronomy students essential skills that will prepare them to work with big data from LSST. It provides a valuable complement for current graduate programs in astronomy, which typically do not include data science coursework. The future of astronomy is inexorably linked to big data, so it’s critical that tomorrow’s astronomers develop skills to help them navigate the vast landscape of information produced by LSST.

This week’s session in Tucson focused specifically on databases and scalable programming. Now that the course is complete, participants will return to their graduate studies with new skills that will benefit themselves and their institutions. In the words of program director Lucianne Walkowicz, “While we can’t teach every student in astronomy, we are empowering our students not only to learn these skills, but to go out and teach their peers too.”

In return for hosting the DSFP on its campus, the University of Arizona was given the opportunity to select four students to audit this session. The students were chosen by U of A based on their interest in acquiring data science skills and the likelihood that they will apply these skills to their future studies. As a result of this course, U of A will boast its own core group of experts in the use of databases and parallel programming that enables analyses to scale to large datasets like those produced by LSST. Additionally, the students will have access to social media channels shared by DSFP students so they can continue to be part of the larger community of future LSST users.

The DSFP is especially grateful for Dara Norman's (NOAO) leadership in coordinating this week's session. For more details about the DSFP program, click here.

April 27, 2017 - Further progress has been made on the Spanish pier. Both azimuth supports are now in place on the Telescope Mount Assembly (TMA), and the main connecting I-beam, known as the "keel," has been attached between them. The orange banks of capacitors were pre-installed on the keel beam prior to its attachment. 

April 21, 2017 –  Fabrication of the Telescope Mount Assembly (TMA) continues in Spain. The large steel structural components that make up the azimuth assembly are painted and undergoing installation on the Spanish pier. A previous post explained the duplicate Spanish pier will be used to support the trial assembly and testing of the TMA prior to its demolition and subsequent reinstallation of the TMA on site in Chile. 

The elevation drive arc, which was machined in March, recently underwent test fitting of aluminum surrogate motor magnets. Meanwhile, the motor magnets have been installed in the azimuth track and covered with plywood to keep them from attracting metal fragments during the assembly process. During operation, the motor magnets in the azimuth and elevation assemblies will allow the telescope to rotate smoothly and quietly on both axes.

The two azimuth supports were inspected and coated this month; one has been lifted into place and positioned, and the second support is awaiting installation. The enormous scale of the TMA is hard to represent in photos; for perspective, the “small” box you can see behind the azimuth assembly in the photo below is actually an office with space for several employees!

April 7, 2017 - Last week was an “other duties as necessary” kind of work week for LSST Graphic Designer Emily Acosta and Telescope Site Manager Eduardo Serrano. Emily traveled from Tucson to Cerro Pachón to meet a nine-member multimedia team directed by Alison Rose of Inigo Films and to coordinate with Eduardo so the media team’s work didn’t interfere with ongoing construction activities. Inigo Films was contracted to document the current state of construction via drone film footage, time-lapse sequences, panorama images, and full dome clips. The assets will be archived in LSST’s upcoming digital asset management system for project viewing and later use in Education and Public Outreach (EPO) programs.

It was important the multimedia work was accomplished safely and with minimum disruption to construction activities. Emily found herself doing a little of everything from coordinating meal schedules, to communicating with site safety managers, to shuttling people and equipment up and down the summit all the while coordinating with Eduardo and Safety Managers Sandra Romero and Giovanni Corvetto.

For five days, Alison directed components of the multimedia efforts. A four-member Santiago-based camera team gathered still photos and video footage with RED cameras, which generate images in higher resolution than HD. At night, astrophotographer Malcom Park captured photos of the Milky Way for time-lapse videos. He also employed a fisheye lens to capture spectacular whole-sky shots, which will be ideal for future planetarium presentations. Finally, a crew of three drone operators spent two days using a Freely heavy-duty Alta Drone, carrying another RED camera, to document construction activity from above.

The group had the fortunate timing to be on the summit for an important project milestone: the arrival of European Industrial Engineering (EIE), the LSST Dome vendor. With EIE joining Besalco, two contractors are simultaneously working on the summit, which makes careful coordination of everyone’s activities even more critical for safety and efficiency. Emily stayed in close contact with Eduardo, Sandra, and Giovanni to ensure the media team could safely access areas as needed to get the most effective images. Media team members followed all safety protocols and wore safety vests and hard hats while they worked in the construction zone, and securely clipped into harnesses when necessary for fall protection.

Documenting the construction process for LSST will result in valuable visual material for construction documentation and LSST’s EPO program. A big thank you to the staff at Cerro Pachón, who all pitched in to graciously host the group during this media project.
