I'm creating a website with views of the worlds of the solar system, to scale with each other (it'll march up and down the few orders of magnitude necessary), and I am having a terrible time finding a global view of Venus to include in it that fits the criteria I'm trying to apply. To the extent possible, I am searching for:
- Full-disk, global view - Minimum phase angle available - Approximate true color, as would be perceived by a human observing the globe from space For Venus, the only global views I am finding are either based on Magellan data (radar views, nothing like what a human would see) or are colorized ultraviolet views (which greatly overemphasize the visibility of cloud patterns in the Venusian atmosphere). I've seen the lovely partial global view of Venus on Don Mitchell's website -- that's the sort of thing I'm looking for, but I need a full disk. Does anybody have any suggestions? Anybody done any work with Mariner 10 or Galileo data that produces a nice, realistic view? -------------------- My website - My Patreon - @elakdawalla on Twitter - Please support unmannedspaceflight.com by donating here.

If you are interested in the surface stuff done by VIRTIS on VEX you can take a look at
http://solarsystem.dlr.de/TP/VIRTIS_en.shtml and http://irsps.sci.unich.it/~luciam/VEX/ The beauty of VIRTIS is that we will for the first time get global multispectral imaging from the surface of Venus over a long time period. |

Great links! I wonder about something...it is thought that, despite up to 16 km/pixel resolution, atmospheric bluring will reduce resolution to 50-100 km. With this being a hyperspectral imager, are they sure that there are no holes where better might be obtained....I know the predictions, but, as they say, he who lives by the crystal ball eats glass. I also wonder if something like a spacecraft role could be used in selected areas for coverage inside of 10,000 km. I am really confused about coverage though. Some of the documents indicate that there will only be coverage of the southern hemisphere, but others indicate the best coverage will be of the northern hemisphere! -------------------- |
