Próximas reuniones con participación LSST 

(aquellos con un asterisco* son financiados por LSSTC):

July 21, 2017 - Technicians, engineers, and scientists who will be working at the LSST facility on Cerro Pachón will often be working “at height,” a term that refers to any workspace four feet or more off the ground. To prepare for their upcoming roles in Assembly Integration Verification (AIV) and Commissioning in Chile, many LSST project employees will be participating in fall protection training courses over the coming year. The first of these courses was offered in late June at safety equipment manufacturer Certex’s facility in Tucson, AZ. During this training, a group of LSST team members learned how to recognize height-related safety risks, and participated in simulations to familiarize themselves with a variety of fall protection equipment.

Whenever working at heights greater than four feet, where no fall prevention structure (such as a guardrail) is present, employees are required to utilize fall protection equipment. At the LSST facility on Cerro Pachón there will be numerous ladders and platforms providing workers with access to different parts of the Telescope and Dome; so fall protection equipment will be a daily requirement for many employees. The recent training class provided instruction in inspecting, donning, and fitting the full body harnesses that support an employee’s weight and distribute force over the body, in addition to keeping it vertical, in the event of a fall. However, the majority of fall protection training is focused on how to prevent a fall in the first place.

LSST Safety Manager Chuck Gessner emphasizes the important distinction between fall restraint and fall arrest. Fall restraint devices, such as lanyards and self-retracting lifelines that attach to workers’ harnesses, allow employees freedom of movement while providing a tether to a secure object. Some even work like the seatbelt in a car, providing flexibility under normal circumstances, but locking when a sudden movement is detected. By contrast, fall arrest involves preventing an individual who has fallen from dropping more than 6 feet. Obviously this type of safety system is critical for preventing injury; however, rescuing an employee who has already fallen can be difficult and time-consuming, and may even put the safety of other employees at risk. It’s far preferable to prevent a fall before it happens.

The focus of safety training at LSST is not just on meeting requirements, but also on developing the skills to recognize and assess safety hazards, and to appropriately employ available safety equipment and follow established protocols when risks are present. In order to ensure that LSST is providing the safest environment possible for its employees, Chuck Gessner regularly researches the safety policies and protocols of other worksites; collecting, refining, and updating best practices to implement for LSST. Safety training courses are available through the project’s Litmos learning management system, and classroom sessions, facilitated by certified instructors, are offered regularly.

Participants in the recent fall protection training class report that it was informative and useful, as well as kind of fun to hang (briefly) off the ground. All LSST employees scheduled to work on Cerro Pachón should keep an eye out for additional fall protection training courses this fall and beyond. You can read more about LSST’s commitment to safety, health, and environmental management practices here, and you can see LSST Training Coordinator Chris Montgomery demonstrating proper harness-hanging form in the LSST Gallery.

July 13, 2017 - Critical work has been underway in the lab at LSST’s Project Office in Tucson, AZ: testing of the static supports for LSST’s Primary/Tertiary Mirror (M1M3). When the 8.4-meter mirror is not under active support by the pneumatic actuators, it will rest on an array of wire rope isolators (also referred to as static supports). 355 of these supports will be installed on the mirror cell deck plate. The supports are designed to safely support the mirror under gravity and seismic loading while limiting the motion of the mirror to safe levels.

Each one of the 355 wire rope isolators was tested individually; the featured image shows an isolator undergoing stiffness characterization testing. During this test the isolator is compressed in a test stand, and the compression force and resulting displacement is recorded while the load is slowly increased.

After testing, the wire rope isolators will be sorted and grouped by their stiffness values. The positioning of the isolators under M1M3 will be determined based on optimal load stress reduction. Stiffer units will typically be placed at larger radii from the mirror center, loosely corresponding to the areal distribution of the mirror’s weight. This placement is important to ensure the mirror, which weighs more than 37,000 lbs (16,780 kg), is supported safely whenever it’s not under active support by the pneumatic actuators. This will occur whenever the telescope not actively observing, but is also important in case of unexpected events such as a loss of power to the cell or the telescope facility.

The Factory Assembly Plan (FAP) Review for the LSST Coating Plant took place from July 5-7 at the Von Ardenne GmnH facility in Dresden, Germany. Members of LSST’s Telescope & Site (T&S) team reviewed the Coating Plant assembly process described in the FAP, including schedule, key personnel, and verification steps.

The glass Secondary Mirror (M2) has now replaced the aluminum surrogate mirror in the M2 cell assembly, which is currently suspended in the testing tower at Harris, Inc. This milestone marks the beginning of integrated optical testing to measure nanometer scale imperfections in the glass surface which will be removed to deliver the correct final shape for the telescope.

The Camera Body and Mechanisms team finalized the Camera shutter design and held a successful Shutter Final Design Review (FDR) June 20 at the SLAC National Accelerator Lab. The team also continued to specify parts that mount to the Camera back flange, the major mechanical interface between the Camera and Telescope.

UPDATED 
July 7, 2017 - Programming provided by LSST for Asteroid Day Live, a 24-hour broadcast about space and asteroids that aired on June 30, is now available on the LSST YouTube channel. You can also find the LSST videos, along with all the other Asteroid Day Live programming, on the Asteroid Day Live website. Read more about LSST’s participation in Asteroid Day 2017 in this blog post from last week. 

June 28, 2017 - Again this year, LSST will participate in Asteroid Day, a UN-sanctioned global day to raise awareness about asteroids and in particular how we protect Earth from potential asteroid impacts. Asteroid Day 2017 takes place June 30th and is sponsored by the B612 Foundation, an American-based non-profit organization created to protect the Earth from dangerous asteroids through early detection. More than 700 events in 190 countries around the world are planned for Asteroid Day in 2017, including Asteroid Day Live, a global 24-hour broadcast about space and asteroids, beginning at 6:00 pm PDT on June 29th. LSST was proud to be selected as a participant in this first-ever broadcast event; video footage featuring LSST will air at 11:00 pm PDT on June 29th. This video will also be available on our YouTube channel and in the LSST Gallery after the event.

Although the chance of a large asteroid hitting Earth is small, the consequences would be catastrophic. At Congress’s direction, NASA has supported a ground-based program to identify Near Earth Objects (NEOs) larger than one kilometer in diameter. But even an asteroid smaller than that could cause significant damage to Earth, so it’s also important to identify as many of these as possible. LSST will help detect millions of asteroids that are too small or too far away to be viewed through currently available telescopes. You can read more details about how LSST will help detect Potentially Hazardous Asteroids (PHAs) here.

Detecting asteroids is not only important for planetary defense, but also for understanding more about the composition and evolution of our Solar System. By scanning the entire night sky in the Southern Hemisphere, and recording images of the same area approximately every three nights, LSST will provide information that will help astronomers determine an asteroid’s size, composition, and orbit. Even asteroids that will never come near Earth can provide us with valuable clues about the formation—and the future—of the Solar System.

We hope you’ll participate in Asteroid Day 2017; check with your local planetarium or science museum to see if there’s an Asteroid Day event happening near you. And don’t forget to tune into Asteroid Day Live for documentaries, live panel discussions, and an inspiring video about LSST!

Sandrine Thomas, Project Scientist for LSST’s Telescope and Site Subsystem, took some time out from her busy work schedule last week to sit down with Alison Rose of Inigo Films for an extended on-camera interview. Interviews were also conducted with LSST Director Steve Kahn, LSST Deputy Director Beth Willman, and LSST Project Manager Victor Krabbendam.

Each of the four interviewees gave his or her own perspective on the rewards and challenges involved in leading a diverse, distributed team tasked with building a revolutionary telescope. The interviews were conducted as informal conversations, allowing for in-depth explorations of interesting topics.

Alison Rose was previously contracted for a multimedia project, featured in a recent blog post, documenting construction of LSST on Cerro Pachón, A short video featuring material obtained during this project can be seen here.

Footage from the interviews and Cerro Pachón construction will be included in a video about the LSST project produced for Asteroid Day Live, a 24-hour online broadcast on June 30, and will be archived for use in future LSST Education and Public Outreach materials.

June 2, 2017 - Members of LSST’s Primary/Tertiary mirror (M1M3) integration team recently completed training on the Leica Absolute Laser Tracker AT-930, a sophisticated tool for collecting precise measurements in three dimensions. The laser tracker will be used for a multitude of tasks associated with M1M3 integration, including accurate positioning of static supports and wedges for hardpoints.

The laser tracker tool has three main components: the laser tracker unit (featured in the accompanying photo), a series of targets called spherically mounted retroreflectors (SMRs), and a software tool that gathers angle and distance measurements using a laser beam emitted by the unit and reflected back from an SMR. If the SMR moves, the unit swivels to track it, taking measurements as it goes. The measurements recorded by the laser tracker are precise within .001 inches, or ¼ the width of a human hair, and up to 1000 measurements can be taken per second.

The M1M3 telescope mirror will have twelve SMRs positioned on towers around its outer edge, and the laser tracker unit will ultimately be located in the mirror’s central hole (although during testing and integration the unit will be moved around as necessary to enable line-of-sight measurements). The laser tracker will be used to integrate first with the surrogate mirror at CAID Industries, and then the glass mirror at the Richard F. Caris Mirror Lab. The laser tracker will be shipped to Chile separately from the mirrors and then will be reinstalled to help locate and test the surrogate mirror, and finally the glass mirror, in the telescope on Cerro Pachón.

SMRs installed on the telescope’s Secondary mirror (M2) and camera will enable the laser tracker to align the telescope’s entire optical system with a programmed series of measurements. These measurements will continue throughout telescope operations and will help detect when adjustments to the mirrors are needed.

The laser tracker, which has been informally described as “magic” and “like something out of Star Wars” by its users at LSST, makes quick work of taking three-dimensional measurements across long distances, as long as it can send and receive an unbroken light beam. It’s an invaluable tool when working with a telescope mirror 27 ft (8.4 m) in diameter!
