<B> Explanation: </B>
We're going in.  
The <A href="http://antwrp.gsfc.nasa.gov/apod/ap051214.html">robotic Opportunity rover</A> currently
rolling across 
<A href="http://www.nineplanets.org/mars.html">Mars</A> has been 
prowling around the edge of the largest crater it has visited since 
<A href="http://antwrp.gsfc.nasa.gov/apod/ap040127.html">landing over three years ago</A>.  
It has been studying 
<A href="http://antwrp.gsfc.nasa.gov/apod/ap061002.html">Victoria crater</A> and looking for a way in.  
Now 
<A href="http://marsrovers.nasa.gov/people/">scientists on Earth</A> 
have decided to take a 
<A href="http://marsrovers.jpl.nasa.gov/gallery/press/opportunity/
20070628a.html">calculated risk</A> and plan to send Opportunity
right into this ancient 
Martian crater over the next few weeks.
<A href="http://photojournal.jpl.nasa.gov/catalog/PIA09694">Pictured
is</A> Cape St. Vincent, part of the wall of 
<A href="http://en.wikipedia.org/wiki/Victoria_crater">Victoria Crater</A> 
next to where <A href="http://antwrp.gsfc.nasa.gov/apod/ap070204.html">Opportunity</A> will descend.  
The wall itself appears to contain clues about the 
<A href="http://antwrp.gsfc.nasa.gov/apod/ap040114.html">Martian terrain</A><A> before the impact
that created Victoria crater, and so will be
</A><A href="http://antwrp.gsfc.nasa.gov/apod/ap070313.html">studied</A> during the daring descent.  
Above the crater wall, far in the distance, lays a relatively featureless 
<A href="http://antwrp.gsfc.nasa.gov/apod/ap061017.html">Martian horizon</A>.
