A new system called Pan STARRS will soon detect NEOs down to a couple hundred meters and more...

"In its first month of observing, Pan STARRS will more than double the number of known asteroids. After several years, the number of discovered asteroids will reach about 10 million.

All NEOs down to a few hundred meters in diameter will be found. If any are possibly going to hit Earth soon, we'll know.

Roughly 20,000 Kuiper Belt Objects are expected to be found (vs. less than 1000 today).

PS can detect a body like Pluto out to 300 AU, Earth out to 600 AU, Neptune out to 1200 AU and Jupiter (or heavier) out to 2000 AU. PS will resolve the question of whether there is a planet X anywhere near the existing solar system (bodies like Sedna suggest there may be something heavy out there.)

PS should detect about 1 interstellar comet per year. These are comets that originated in some other solar system and were then ejected into interstellar space, a fate that befell about 90% of the comets in our early solar system as well.

Determine the position and distance of all stars within 100 parsecs of Earth visible from the site.

Find roughly 100 extrasolar planets by occultation.

Detect all Andromeda-size galaxies in the universe that are visible from Hawaii, all the way back to the start of galaxy formation more than 12 billion years ago."

The best news is that now Ol' Uncle Eddie won't need Mark's 'Mars money' anymore with this new system.
