August 29, 2007, HiRISE release
Interesting new image of the Arsia Mons pit. The polar pit gullies image is pretty good, too. |

A study document for the 2013 Mars Science Orbiter (available at the MEPAG website) weighed the advantages/disadvantages of sending a camera with 10 to 15 cm resolution. To eliminate pixel smear, they considered moving the CCD array during image acquisition, rather than moving the entire camera or entire spacecraft.
Ultimately, they decided that the weight of such a camera would be excessive and a HiRISE-class camera would be sufficient, given how little of Mars will be imaged by HiRISE itself during its lifetime. BTW, a HiRISE camera is not guaranteed for 2013, and will be competing for payload inclusion against things like an imaging SAR and advanced atmospheric instruments. A resolution of at least 10 cm should be technically achievable from Mars orbit. Unclassified sources estimate that U.S. reconnaissance satellites get at least 10 cm resolution, and the Earth's atmosphere should be more of a challenge to compensate for than Mars'. Except during planet-wide dust storms, of course. |

There are anecdotes from the latter cold war years of espionage agencies being able to identify individual license plates on vehicles. The letters on my California plates (assuming they are typical) are about 6 cm tall. Clearly you'd need resolution on the order of 2cm or finer to read them -------------------- If Occam had heard my theory, things would be very different now.
