APOD entry 1.2

The APOD picture I chose was of the Victoria crater (September 4th), a potentially traversable crater on the Martian surface. The picture was taken after dangerous dust storms (dangerous because dust blocks sunlight from the Opportunity rover's solar battery panels) and the trip into the Victoria crater has been much anticipated since July. It's lucky that the picture happened at all seeing as the rovers have lived three years past their anticipated three month expiration date, and the rovers have been searching for a way into Victoria crater for months. Victoria crater is the largest crater the rovers have found, and NASA hopes the rover will be able to go inside of the crater itself. NASA plans to keep the rover in this area in case the dust storms resurge (it will be in more view of the sun here) and in case we can find a way in. NASA hopes that the crater's walls will hold evidence about what the Martian surface was like before the impact that created the crater happened.
