Summary

[edit]
Description

My that’s big. Here are the notes I took on my phone during a tour at SLAC. That’s Steven Kahn, deputy director of the Large Synoptic Survey Telescope (LSST) speaking:

It has 200 4K*4K pixel sensors, costing $100k each (yes, a $20M imager!)

f/1.23 lens

Very wide: 40x the field of view of the moon in the sky.

It will collect 30TB of data per night, over 10 years of continuous operation, we will see everything that is moving.

Will see 4B of 100 B galaxies, about one per person on earth.

We will see the weak gravitational lensing effect of dark matter.

We can track near earth objects and the asteroids’ trajectory back to their formation origin.

Currently under construction in Chile, with first light in Jan 2018 if funded. Gates and Simonyi funded the main <a href="http://www.lsst.org/lsst/gallery/mirror-casting/Group_photo" rel="noreferrer nofollow">mirror</a>.
