No trick (follow the link clicking on the image); remember that a polished metal plate acts as a mirror.
But don't ask me which IDD instrument is that black box (Mossbauer maybe?) |

I think it's the electorincs box for the micro imager. There are similar shiny boxes next to all the cameras.

There's no Mossbauer this time. Indeed, one surprise in the MSL payload is the total absence of any devoted mineralogical instruments on MSL other than the X-ray diffractometer that requires the actual ingestion and grinding of samples -- no Mossbauer, no Raman, no near-IR or thermal-IR spectrometer (although the flash spectrometers for ChemCam can do some reflection-spectrum work as well). The only two instruments on the arm are the color microscopic camera and a near-duplicate of the APX element spectrometer from the MER rovers (which, I've been told, is there largely as a backup in case ChemCam doesn't work as well as predicted).

Still no EDL video?? I'd like to add it to my collection.

--><div class='quotetop'>QUOTE(Toma B @ Jun 6 2006, 01:55 PM) </div><div class='quotemain'><!--quotec--> Looks to me like there is some work to be done on that rendering like adding RTG's... It is strange that nearly every image of MSL has it without its RTG. Very strange, is it expected to be powered by dark energy? Probably they keep it out of the publicity images to keep a lower profile since there are some groups that adamantly oppose *anything* nuclear. Even peaceful scientific missions... Also, the camera on the mast surprises me. Would they not have two camera's for binocular vision? How can they tell distances without it? I could have sworn that there were some pictures that did show the probe with RTGs fitted, which made it look somewhat like a bombardeer beetle, but they seem to have disappeared from the net unless someone has copies. |

Any updates on the MSL entry and landing video? Also, has anyone heard if JPL/NASA has chosen a snappy name, for the MSL yet? Perhaps, something like Phoenix or Ares or Lance Armstrong? Another Phil |

Another Phil Will be getting another opportunity this week to see the video again. Will try to get it. Phoenix was the name of the project from since its proposal. ARES is an acronym. It is too early for MSL |

For those interested in MSL's RTG system, here is the link to a great paper summarizing the design. It looks like they have it figured it out, at least in the engineering world. Perhaps, it is the world of politics, or the availability of Plutonium, or both, that is holding back a definite decision. http://marstech.jpl.nasa.gov/publications/...-2005-01-28.pdf Another Phil |

Russia has said to the US that the US can buy Plutonium-238 for $2000 per gram from Russia if and only if it is NOT used for any military purpose. Russia has lots of Plutonium-238 to give the US!
The US has said it will resume domestic production of Plutonium-238 as soon as possible. It is most likely that there is a lot of political sensitivity to anything nuclear. Just look at the fuss over the Galileo, Cassini and New Horizons missions! If we told the people that RTG's were used in the Viking landers, then I'm sure most of the fuss will go away. Protestors are strange people. No one protested against the launch of the Voyager 1 & 2 probes. Why? Voyager 2 was launched on August 20, 1977, just 4 days after Elvis Presley died! And Voyager 1 launch date (on September 5, 1977) was during the immense grieving over his death! -------------------- I call heaven and earth to witness against you this day, that I have set before thee life and death, the blessing and the curse; therefore choose life, that thou mayest live, thou and thy seed.

And Voyager 1 launch date (on September 5, 1977) was during the immense grieving over his death! I recall one quite vocal anti-nuke protestor who was not only deeply concerned that Cassini would somehow fly back to Earth and crash on it after exploring Saturn but that during the probe's 1999 flyby of Venus that NASA should have let the craft smash into the second world from Sol because the planet had no atmosphere! I was also told by a friend who attended an anti-Cassini (read anti-nuke) group meeting in Cambridge, MA in 1997 (home to Harvard) that when he tried to explain how safe Cassini's RTGs were even from an explosion of the rocket, he was told they didn't want the facts because they had already made up their minds that Cassini was dangerous and had to be stopped. After all that, any amount of sympathy I had with the anti-nuke groups went right out the window. BTW, Groucho Marx died around the same time as the Voyagers left Earth and Elvis went into hiding, but sadly people didn't seem as upset about his passing. -------------------- "After having some business dealings with men, I am occasionally chagrined,
and feel as if I had done some wrong, and it is hard to forget the ugly circumstance. I see that such intercourse long continued would make one thoroughly prosaic, hard, and coarse. But the longest intercourse with Nature, though in her rudest moods, does not thus harden and make coarse. A hard, sensible man whom we liken to a rock is indeed much harder than a rock. From hard, coarse, insensible men with whom I have no sympathy, I go to commune with the rocks, whose hearts are comparatively soft." - Henry David Thoreau, November 15, 1853 |

Basically, MSL will be like a large car radiator! This has to be a much simpler design than electrical heaters, but I worry about leaks that could happen (like my car's radiator ). |

hmm.. "The working fluid is CFC-11".
I guess we do not have an ozone depletion issue on Mars (...probably we need a little more atmospheric oxygen ) -------------------- I always think before posting! - Marco -
