Well, darn. For all the planetary scientists who were hoping to see what happened when 2007 WD5, a rock half the size of a football field, slammed into Mars while we had plenty of instrumentation in Mars orbit and on the surface to analyze the results - well, it's not going to happen. WD5 had a 1 in 25 chance a few weeks ago. Now that further information has been gathered on its trajectory, we know know the chances are miniscule. Any Martian microbes are presumably OK with this, but it's a letdown for Earth.
