It was Nathan's anecdote to counter an assertion by Amy that LSST could not spot any asteroids within Earth orbit.

But 'any' is a very strong word. There are twilight and dawn, so LSST will get some. /2

Myhrvold said Mainzer claimed LSST couldn't observe anything less than 90 degree angle (forget exact term).

Okay, let's not get into he said she said. Mainzer would be insane to make such a claim. For that matter, anyone who has seen /1

Ivesic said that was a common misconception about LSST among asteroid researchers. I really did do a lot of reporting.

The Tianhe-2 supercomputer can also do the work of a powerful gaming PC. There is a point of efficiency and optimization. /2

LSST will find more than a few NEOs. Even the Grav/Mainzer/ Spahr paper said 60%.

Ivesic says 80%+ with optimization of the cadence. Then it's reasonable to ask cost/benefit, no?
