STEP File Import

After reviewing my latest posting, I noticed that I was able to zoom and rotate the STEP files included with the graphics.  Dumb question - has the STEP file viewer always been included on Instructables or is this a relatively new feature?  Anyway, it's a nice feature for people that want a better understanding of the part.

High Resolution view of Victoria Crater on Mars

NASA has released a beautiful high resolution picture of Victoria Crater (below) taken from the Mars Reconnaissance Orbiter. If you zoom in on the full resolution image, you can see the Opportunity rover's tracks and stopping points (faint lines with bright dots) around the left part of the rim.The photo was taken in July 2009, so many of Opportunity's tracks have already been obscured by wind and sand.
