QUOTE (akuo @ Apr 11 2006, 07:59 AM)  Emily has been busy. Almost the whole PC is already transcribed on the blog: http://planetary.org/blog/ I really enjoyed reading about Mars on this website but I must send out a big thanks to all you posters and members of UnmannedSpaceflight as well as the fantastic blog of Emily, you guys have given this Venus event fantastic coverage |

This is great news - congratulations to ESA (and thanks to Emily for detailed news from VOI and the PC).
Now we can look forward to seeing the first images two days from now. It's rather strange that with the exception of 50-100 Galileo images and a few from Cassini these will be the first spacecraft images from this closest neighbor obtained using a modern camera system. |

Europe Scores New Planetary Success: link Changed to a link - seriously, hundreds of lines ot text in a forum post doesnt make a lot of sense when you can just link to it with the pictures in situ etc. - Doug -------------------- "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 |

QUOTE (ljk4-1 @ Apr 11 2006, 01:56 PM) The PFS spectrometer will determine the temperature and composition profile of the atmosphere at very high resolution. So has the VEX PFS fixed itself then? |

I don't think so - IIRC they were going to try the PFS cover again some time after VOI. That text just looks like a copy/paste job into the press release...
...and my congrats to ESA on the successes of VEX & MEX too! Now I think I'll go get some TEX-MEX for lunch

Let me add my kudos to ESA and their fantastic job. Time to dust off the old Venus books!

There's a bit more from two abstracts from the Fall 2005 AGU meeting on just what they hope to do with VIRTIS where surface observations are concerned:
http://www.agu.org/cgi-bin/SFgate/SFgate?&...P33A-0227" http://www.agu.org/cgi-bin/SFgate/SFgate?&...P33A-0225" Also, Noam Izenberg's presentation to last November's VEXAG meeting on the observations MESSENGER will make during its second Venus flyby ( http://www.lpi.usra.edu/vexag/Nov2005/MESSENGER_VEXAG.pdf ) includes, on page 8, a description of a possible attempt to mkake similar observations of surface composition |

QUOTE (Richard Trigaux @ Jun 26 2005, 08:06 AM) This was all the more true for Huygens, which images were ridiculously small and tremendously compressed. The images are not rediculously small...they are framelets....they were never intended to be stand alone images, but rather combined into panoramic 360 degree images. With early 90s technology, as edstrick said, this instrument did a very good job given the data rate/mass/power use constraints. It would have been better to have few images with less compression had both channels been received (with only one received, we would have horrible holes in the mosaics). But this is simply a result of Titan providing a lower contrast environment than expected. -------------------- |

That very nice (and pictorial) document on the DISR photos from last year's Titan Conference which I mentioned down in one of the Titan threads yesterday says that we did manage to get three "almost complete" mosaics, as opposed to the 10 hoped for.

Wait until June 4, 2006 when Venus Express start to collect observations from Venus. Now it is undergoing the switching on every 7 scientific instruments.
Until beginning of June, Venus Express will continue its ‘orbit commissioning phase’, started on 22 April this year. "The spacecraft instruments are now being switched on one by one for detailed checking, which we will continue until mid May. Then we will operate them all together or in groups" said Don McCoy, Venus Express Project Manager. "This allows simultaneous observations of phenomena to be tested, to be ready when Venus Express’ nominal science phase begins on 4 June 2006," he concluded. Venus Express will live for only 2 days !  While Venus Express is expected to spend about 15 months studying its cloud-covered target, the mission will span only two of the world’s exceedingly long days. Rodolfo |
