		<description>After further review as described at http://neo.jpl.nasa.gov/news/news156.html as of 8 January 2008, there is a 1-in-10,000 chance that it will hit. I hope they get good pictures.

If there had been a warning, it would now be reduced to a level 0 (no need to worry) or level 1 (may be interesting to view).</description>

		<description>I&#039;d hope that various planetary scientists are considering the possibilities. There aren&#039;t seismographs on the rovers. But this would dig a deep hole, and there could be good pictures of impact (if it happens) or as it&#039;s zipping by. I hope it doesn&#039;t raise too much dust and cover the rovers&#039; solar panels.

The rover science instruments are described at http://athena.cornell.edu/ but the news there is older.

They probably won&#039;t get good pictures of 2007 WD5&#039;s approach because that is sunward from Mars. That&#039;s part of the problem with getting better orbit calculations. The geometry isn&#039;t good for observing the asteroid from Mars. But Earth&#039;s Moon will move out of the way from Earth&#039;s perspective.

Scientists are lucky that the asteroid came by Earth before heading toward Mars so that it was noticed. If it were coming in from a different angle, they might not see it.

By the way, I created the part about 100 sols in the first paragraph to mimic the tropical advisories. The Torino Impact advisories for Earth have decade timeframes and don&#039;t seem to address &quot;It might happen next month.&quot;</description>

		<description>I wonder if Opportunity will be able to record the (possible) impact from its location. Would be nice research on impacts. especially on Mars.</description>
