LRO development Options

Just read this interesting article about LRO

http://science.nasa.gov/headlines/y2005/28apr_lro.htm

"This is the first in a string of missions," says Gordon Chin, project scientist for LRO at NASA's Goddard Space Flight Center. "More robots will follow, about one per year, leading up to manned flight" no later than 2020."

One per Year? Is this just wishful thinking or have any tentitve plans been mentioned for follow up missions after LRO? If the next one is going to be 2009/10 then I guess some desisions about it will have to be made fairly soon.

In fact, Bob, the footprints and wheel tracks near the LMs were not at all darker than the general soil at the landing sites. The LM DPS exhaust would sweep the top layer of dust grains from the regolith during landing, resulting in a temporary brightening of the soil around the LMs. "Darkened" footprints and wheel tracks were simply *restoring* the soil's natural albedo within the splash of brightened soil.

There is some question, I guess, as to whether or not the local soil brightening around the LMs still exists. I don't believe any of the Clementine or SMART-1 or Lunar Prospector images were able to answer that question -- though Phil probably knows the answer to that better than I do.
