I'm having a hard time figuring out what the current status of HiRISE is from the myriad of articles currently being written. The NASA/JPL news release refers to "a significant increase in noise, such as bad pixels, in one of its 14 camera detector pairs." while the Nature story refers to "Seven of HiRISE's 14 detectors are sending back spurious data, the mission team reports, and one of the four colour detectors has stopped working completely."
Which color detector is lost? It would seem to be less damaging, from a public release standpoint, if it turned out to be one of the two infrared detectors, since the two blue/green detectors are what we have seen used for color images. Also, is the nature story exaggerating by referring to the color detector as completely stopped or is the JPL release euphemistically telling us that same thing? A little disambiguation might go a long way here. |

QUOTE (slinted @ Feb 11 2007, 03:55 PM)  the Nature story I have no idea what the actual situation with HiRISE is, but it would be nice to get an official and unambiguous statement. The media reports do make it sound pretty bad. From the Nature story: "A previous high resolution NASA camera was lost with the demise of MGS. The best camera currently in orbit around the red planet is on Mars Express, which arrived in December 2003." Given that the SRC system on MEx hasn't performed to spec, I think that CTX on MRO at 6 meters/pixel wins the prize for next best camera, at least in terms of resolution. -------------------- Disclaimer: This post is based on public information only.
