Maybe they are. Each target obviously takes time to identify, prepare the system, fire, analyze the results, possibly fire again (the first firing might be to remove dust), analyze again, and then move in closer for APXS or other instrument analysis. Why are you assuming they'll move in and APXS every ChemCam target? |

Did they mention how they're going to handle dust on the optics? A laser powerful enough to vaporize rock is going to vaporize any dust on the optics as well. That's probably not a good thing.

Jen Blank presented information about ChemCam at Seti Institute two months ago. The video is here:
http://www.youtube.com/setiinstitute#p/u/11/887bilE-C4s I can't remember if she addressed the questions posed in this thread, but I do remember the talk being informative. |

Glad to see her coming together so well!
Late comment on duty cycles for complex systems: Ask any aircraft mechanic anywhere in the world how planes behave if they sit idle for too long; you'll get an earful. My guess is that near-continuous operation of a system within normal parameters (vs. near upper tolerances, as is often necessary with high-current devices) actually reduces the likelihood of malfunction since the individual components are subjected to their designed operational loads & environment (thermal being probably the most significant) as well as generally steady inputs from interfacing devices. What frequently kills integrated systems are abrupt transients (mechanical & electrical), and those are more likely to arise due to subtle, often random, changes in the performance of individual components that occur for a variety of reasons as a result of prolonged periods of inactivity. -------------------- A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

Some really beautiful pictures of MSL cruise stage testing:

Thanks + I see there'll be a "A public lecture by Mars Science Laboratory Chief Scientist John Grotzinger, of the California Institute of Technology in Pasadena, will take place at JPL on Thursday, Sept. 16, beginning at 7 p.m. PDT Time (10 p.m. EDT). Live video streaming, supplemented by a real-time web chat to take public questions, will air on Ustream at http://www.ustream.tv/channel/nasajpl"

I'm going to go to the PCC one on the Friday.

Five Things About NASA's Mars Curiosity Rover
http://www.jpl.nasa.gov/news/news.cfm?release=2010-302 One error I found in this article is Pathfinder being called Curiosity's rover predecessor. Pathfinder is obviously the lander. Sojourner should've been listed. -------------------- 2011 JPL Tweetup photos: http://www.rich-parno.com/aa_jpltweetup.html

I am not sure how long these have been up, or if anyone has noticed, but there are two Mastcam 100mm images taken with I assume an engineering version outside, with an image in bayer color and through an IR filter on the science corner website. Sadly, they are not full res. One can just imagine those images taken on Mars though
http://msl-scicorner.jpl.nasa.gov/Instruments/Mastcam/ Also I might point out, there is also some nice pictures of MARDI attached to the rover on the MARDI page. |

There's a test image here
http://www.msss.com/news/index.php?id=14 And for MAHLI http://www.msss.com/science/msl-mahli-pre-launch-images.php And MARDI http://www.msss.com/science/msl-mardi-pre-launch-images.php And I just learnt that, like MastCAM and MARDI - MAHLI can record video as well. http://www.msss.com/msl/mahli/references/E...l_MarsMicro.pdf |

Pretty neat idea, using the "leaky" IR range of the Bayer filters to get IR on an RGB camera. Would there be any advantage to a R-G-B-Clear filter pattern?
