From the BBC:
The US space agency has issued another of the "selfie" portraits acquired by the Curiosity rover on Mars.
Nasa tries to make one of these mosaics at every location where the robot drills into the surface.
This latest picture was taken by the rover at "Buckskin" - the seventh rock target on the mission to provide a sample for analysis.
The portrait differs from previous ones in that it is taken from a low angle.
Curiosity manages this smart piece of planetary photography in the same way that any human would take a selfie - by holding a camera at arm's length and framing its own form.
The camera used is the "hand lens" known as Mahli. Normally used to study mineral grains in rocks at very close quarters, it can also be focussed on infinity.
Engineers instruct Mahli to send back multiple shots of the rover, after first practising the shoot sequence on a test vehicle kept on Earth.
The pictures must then be stitched together to make the final scene.
Good copies of the 'selfies' were also found on Engadget.

The NASA site has more pictures [nasa.gov].
At least, this selfie shows a clipped arm as you would expect from a stitched image. I never really understood how they managed to hide all traces of that arm in the June 2014 selfie [nasa.gov].

Couldn't they do something a bit more dignified with the clipped arm, such as put a '76 ball on it? (The younger crowd may not remember those.)
