In November 2017, another piece of the puzzle came together when the M1M3's surrogate mirror was mounted to its cell at CAID Industries in Tucson, Arizona.
Getting a lift
The LSST project is so big it needs a vertical lift platform to get the job done. This lift was installed at the Chile site in December 2017. It'll move the mirrors and camera, up and down, for maintenance.

Money from billionaires
In the works since the turn of the 21st century, the LSST project got a $10 million boost from Bill Gates in 2008.
The Microsoft founder was taken by plans to share the telescope's data with the public. "LSST is truly an internet telescope," he said.
