The Mirror Lab is currently working on the Giant Magellan Telescope project.  This 24.5 meter telescope will consist of seven separate 8.4 meter segments. Each mirror takes a little more than a year to create the mold and cast.  After casting, the fabrication of each segment requires three plus years of surface generating and meticulous polishing. 

Status as of September 1, 2017

Segment 1 primary off-axis mirror was cast on July 23, 2005 and was completed in 2012.

Segment 2 primary off-axis mirror was cast on January 15, 2012 and is currently in the early stages of front surface generation.

Segment 3 primary off-axis mirror was cast on August 25, 2013 and has just completed the installation of load-spreaders on the rear surface

Segment 4 prmary on-axis (center) mirror was cast on September 18, 2015 and is rear surface polishing phase. 

Segment 5 primary off-axis mirror will be cast in November, 2017 and currently the mold has been completed.
