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.

This may be about as good as you can get from Earth for a true-color photo of Venus in a full phase. Taken by amateur Arnaud van Kranenburg back in 2006 as part of the amateur campaign to assist Venus Express. The leftmost image in the second row is RGB, and seems close to true color, and Venus is 98% full. If you wanted to "convert" this to 100% full, it would do pretty well to copy the right limb and reflect it over the left side, which features the almost-full terminator.
http://sci.esa.int/venus-express/40018-vaop-images/ What's lacking is resolution – Venus was on the far side of the Sun and the instrument was only a 9.25-inch telescope. However, since there is likely next to no discernible detail to be had at higher resolution, it's not too hard to upscale + blur (+ deconvolve) this into a very good simulation of what the same view at higher resolutions would resemble. |
