If all goes well, Venus Express will be a major topic for discussion in this forum a year from now. Does anyone know how good the surface coverage will be from VIRTIS and VMC? My understanding is that VIRTIS will obtain low resolution multispectral maps, and that VMC will, in addition to cloud monitoring, have one channel that can see the surface, but I don't know at what resolution or at what quality. It will be nice to have some non-radar images of Venus' surface besides the Venera snapshots and the shadowy images from Earth and Galileo's NIMS.

New VEX Science Information Released
On the ESA Science page at: http://www.esa.int/SPECIALS/Venus_Express/ there are two new releases that you might find interesting. The first shows some great 'movie' images taken by the VIRTIS imaging spectrometer of Venus' south pole. Combining the IR images with a UV image of the dayside, you can see the full rotation of the south polar vortex. Over a period of five orbits, VIRTIS took images centered around apocenter. The page strings them all together, so that you see the five or so shots from one orbit, and the sudden jump is when the data jumps to the images from the next orbit. You can really see the change in the cloud structure over time in the vortex. Just released is an article about ground-based observations that will be taking place in coordination with VEX. This will extend up to the Messenger Fly-By in early June, when we will be (sort of) simultaneously taking data from Messenger, VEX and the ground. Over the next few months, Venus will be around its closest distance to Earth (inferior conjunction). Planning began this week for late August through late September, slightly past conjunction, and during that period we'll also be coordinating VEX observations with some ground observations: - Infrared observations will be made by the Infrared Telescope Facility (IRTF) facility in Hawaii, USA. - Sub-millimetre observations will be made for two days with the James Clerk Maxwell Telescope (JCMT), located in Hawaii, USA. |
