Thanks for posting this, @Temujin.

I'm a keen amateur astronomer and space/physics/astrophysics follower. You can visit the LSST website here https://lsst.slac.stanford.edu.

Took me a while to figure you were talking about the camera lens, not the telescope mirror, which is already in Chile. This is part of a large and very complex project: https://en.wikipedia.org/wiki/Large_Synoptic_Survey_Telescope

Yeah, this is the lens for the 3.2 gigapixel camera... the starbucks instagram coffee image posters must be losing their minds

Most astronomical telescopes do not have a lens for the camera, since they operate at the prime-focal point. LSST is rather different in its overall design, and particularly its wide field of view (the opposite of the Hubble space telescope).

Speaking of the LSST, this piece gives some info on the sort of thing LSST can help resolve, though it might take decades.

The case is mounting that we might be making some serious mistakes in our measurements of the universe.

The telescope should detect killer asteroids and may even find the ninth planet in our solar system.

Maybe they'll use it to look at this new arrival;

Yip. Long term covid. There is some improvement but still hectic. Anything triggers and puts her back in bed for days
