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

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.

Is 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.

If 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.

Exactly its at Arizona: Steward Observatory Mirror Lab

According to the site, the GMT will cost around $700mil

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. LOL

City cop just driving around with a near flat tire, followed him for miles, he had to stop and get him some mexican food tho.

Broken back, busted up insides, he fell 60+ feet, hit ice bridge and bounced to the ground. I had to snap a pic, couldn't get down fast anyway.
