Until recently, eyeglass lenses were actually made of glass-remember the "Coke-bottle-bottoms" some people had to wear? Given the fragility and other quirky qualities of glass, you can imagine the delicacy with which the optician had to grind every lens blank to achieve exactly the right specifications. Now picture 492 glass pieces -...
The year started at full speed for the TMT Observatory Software (OSW) team, who met in Pune, India with their colleagues from the India TMT Coordination Center (ITCC) and ThoughtWorks engineers to conduct their 3rd Common Software (CSW) sub-system inception meeting.
“Wax on, wax off,” said Mr. Miyagi to "The Karate Kid" (1984), to help the kid develop efficiency of movement, attention to detail, and grace—while also polishing Mr. Miyagi’s classic car. What could this possibly have to do with TMT?
As I’ve explained elsewhere in this blog, segment support assemblies are what hold in place each of TMT’s primary mirror segments. They also let each segment be positioned in real time to provide the best possible imaging capability. Staff at the TMT Project Lab in Monrovia, California, are building six segment support assemblies to determine whether the design can be manufactured in a repeatable, problem-free manner.
It’s been some time since my last blog entry because TMT has been keeping me rather busy. I’ll talk about some of the latest happenings in upcoming entries as soon as time permits. However, before letting any more time go by, I’d like to take a moment to highlight TMT’s WFOS system.
The shipment of TMT’s first meniscus-shaped primary mirror segment to the Indian Institute of Astrophysics (IIA) in Bengaluru (Bangalore) has just been completed.
TMT’s Narrow Field InfraRed Adaptive Optics System (NFIRAOS) successfully passed its final design review and is ready to proceed to the fabrication phase, which is expected to last approximately four years.
Following a successful second IRIS Preliminary Design Phase Review (PDR-2) at the TMT Project Office in Pasadena, IRIS is proceeding into its Final Design phase. The focus of the second review, held in September, involved an assessment of the IRIS software (including its data reduction system) and electrical design (including its detectors) as well as programmatic aspects spanning project cost and overall schedule.
Marking a major production milestone, TMT has entered into a contract with Coherent Inc., one of the world’s leading providers of lasers and laser-based technology for scientific, commercial and industrial customers, to polish its U.S. manufactured primary mirrors (M1) segments.
Representatives from the Thirty Meter Telescope’s (TMT’s) Wide-Field Optical Spectrograph (WFOS) team and TMT’s China partners gathered on October 16 in Beijing, China to discuss potential collaboration during the next stage of the conceptual design of WFOS.
