Shooting lasers
A lab demonstration of the measurement chamber inside the Tunable Laser Spectrometer, an instrument that is part of the Sample Analysis at Mars investigation on the Curiosity rover. The demo uses visible lasers – rather than the infrared ones on the actual spectrometer – to show how the lasers bounce between the mirrors in the measurement chamber.

I find this pictures really fascinating.
But there is one question, which leaves me no calm:
How such "Self portrait" could be physically when only single one (to my knowledge) robot exists on Mars?!

It looks like that photo made by standalone observer - no physical contact between camera and robot is visible on this picture.

From what I recall: that's taken from a camera on the robot arm. So it's like taking a photo of yourself at arms length.

Right, but when you do a self portrait, you always see the arm that holds the camera. I can't see any arm on the photo, like if the camera was floating about or standing on a tripod.

Ok, now I understand: this is a mosaic: the arm is not on the final picture, but must be on each single pictures. Cool!

Here are the details of the MSL self portrait photo: http://www.nasa.gov/mission_pages/msl/multimedia/pia16239.html

I take it that this is more or less like taking two self-portraits; one with the right hand and one from the left, then cutting it apart and stitching together the two sides when each was not holding the camera.
It makes for a pretty interesting self-portrait and at first glance doesn't seem possible.

This is sooo coool. Science and human endeavor at its best.
Thanks for the coverage, George,
BTW, two lead engineers from Curiosity were on the NPR comedy program "Wait, Wait Don't Tell Me." Not only are they smart, they are funny!
