I thought it was time to start a separate thread on this mission, launching soon
some good medium-resolution images of the spacecraft are available on JAXA digital archives http://jda.jaxa.jp/jda/p3_e.php?time=N&...mp;mission=4066 |

A couple of attempts to merge the sunlit cloud deck imaged in near-UV and near-IR with nighttime thermal data taken at the 2.26 micron wavelength, which appear to be the least overexposed of the 2 micron camera images. The two sets of images were taken up to 2 hours apart, so the geolocation of these images probably isn't super accurate but should be fairly representative. I've also added a heat colormap to colorize the thermal infrared data - the scale doesn't correspond to specific temperatures or anything, it's just there to enhance some of the detail present in those images while also emphasizing that it's thermal data.

Nice display of IR! It certainly gives the impression that we should not touch Venus without protective gloves.
It's hard to tell from just a couple of images, but I'd like to see a global average of limb darkening. There should be some limb darkening but in any single image, the regional variations are a bigger factor. |
