To clarify a few things here that seem to be leading to some confusion:
1. As 'anhinga' correctly stated in the post above, The Mars Reconnaissance Orbiter (MRO) is working just fine and is still taking
pictures. These pictures from the OP are from that MRO (which has the HiRISE camera on board).
The probe that was lost was the Mars Global Surveyor. It was already way past it's expected life when it was lost, but it in fact was lost
because of human error. But as I said, even though the Global Surveyor was lost, MRO is still in orbit taking these breathtaking Hi-res pictures
(much more hi-res than the Global Survayor was capable of), and is scheduled to stay operable for several years.
2. Also, as the OP alluded to, these pictures are NOT TRUE COLOR. The article even states that the colors have been enhanced and do not look
like they would appear to the human eye. NASA often assigns different contrasting colors to different intensities of light to help see
different materials better. NASA calls these Enhanced Color photos. Sometimes things which we see as blue and yellow in these Enhaced Color
photographs are just different shades of reddish-brown when seen in approximate true color.
NASA uses the term approximate true color for pictures most of us would call "real color pictures". They use the word 'approximate'
because there is no such thing as a true color camera. All digital cameras (including the one you own) take pictures in shades of grey
and use filters and computers to create "approximate true color" pictures, based on the intensity of light.
The photos in the OP are not "Approximate true color', but are in fact 'Enhanced Color'
Having said all that, these are certainly stunning photos, and thanks for posting them. Cool.
