It's crazy to think how big mustangs have gotten over the years

Went to San Diego this past weekend. Pics from La Jolla and Fort Rosecrans Cemetary on Point Loma

Ive got tons more!
Took a tour of the Steward Mirror Lab which is under the University of Arizona Football Stadium. Most people have no clue its there or what it being worked on. This is 1 of the 7 mirrors they are building for the Giant Magellan Telescope that is being built for Chile. It will be 10x more powerful than the Hubble Space Telescope. It is the only lab in the world of its kind. The tour guide stated 1 of these mirrors would allow you to read a newspaper over 5 miles away. Here they are buffing the surface down to prep it for the aluminum coating. There's about 20 tons of glass in this piece alone, the glass comes from Japan. The project for the mirrors alone is well over $25mil. Each piece will be driven to Houston and put on a ship bound for Chile.

Exactly its at Arizona: Steward Observatory Mirror LabIs that the lab that does the spin casting of mirrors? I did tour the lab at the college that was experimenting with that technology. They were able to make mirrors that required far less grinding to reach the final figure.
Ya they mentioned all the dimensions, I wish I would have recorded some of it. I do remember him saying the top layer of the glass is 25 nanometers or about 1,000th the thickness of a human hair. LOLIf I'm not mistaken those mirrors are ground so smooth the variance in the surface from peak to valley is like 25 molecules tall or something like that. It is amazing how precise they can be ground.
Around my way we call that "Ratchet"...
