An Interesting Picture From Mars

"NASA recently posted an image taken by the Mars Hand Lens Imager (MAHLI) aboard NASA's Mars rover Curiosity. A reader from Australia contacted me to point out some curious structures within the rock featured in that image. I get a lot of emails like this. Normally these emails include something that the reader has totally distorted using Photoshop or contains some blurry shape on Mars that reminds them of a household appliance or cute little animal. I am a biologist and used to work at NASA's life science division and have done some fossil collecting in the field. So I've looked at things before that look like they are fossils only to determine that they are the result of non-biological processes. I noticed something curious about this image right away. ... I have sent an inquiry to NASA. Let's see what they say. I'll include their response in a revised version of this posting."

Keith's update: My original source in Australia heard from someone@nasa to the effect that these markings are the result of the laser used to analyze rocks but that the markings look different this time. I am still awaiting an official response directly from NASA. Today's lesson: when looking for life on another world it is important to remember what is happening on both sides of the microscope.
