I'm used to reading excellent articles by Emily, but this one I found to be of truly extraordinary interest:

I suppose I should say that, after LCROSS and the mystery of the incredible plume, I'm all in favor of NASA making conservative predictions but being prepared to record spectacular results.
It's funny; there's not a lot of buzz about WISE, but between brown dwarves and optically-dim Earth-crossing asteroids, it promises to deliver an incredible wealth of information. If they manage the extended mission, they'll have two shots of each object, six months apart. Since their resolution is 2.75 seconds of arc per pixel, that ought to give them a good clue as to which objects at least MIGHT be associated with the sun. Too much or too little change in position would mean it's either going to fast or located too far away. --Greg |
