Today's Mars Photo is of Tisdale-5, a rock in close proximity to the original Tisdale. This rock is one of the more oddly shaped rocks in the area and seems to have been eroded significantly over the past millions (or billions) of years. We are left to wonder why the Mars Exploration Rover Opportunity's team decided to group many rocks under the name Tisdale, but it is likely because the team believes the rocks have similar composition. This photo came directly from The Road to Endeavour blog and the full size image can be seen just by clicking on the image below.
I failed to post a photo yesterday (Aug 28 2011) because I got caught up in Hurricane Irene and my power and Internet are out. I found a hot spot to post today's Mars Photo of the Day. Hopefully I'll be able to post more regarding developments toward Mars travel and exploration when my Internet is restored tomorrow. Thanks for your patience!
