Congratulations to the InSight team on a successful landing! We'll discuss the remainder of the mission here.
-------------------- A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

Just playing here, with the 3 IDC images making 2 pairs. These are difference images showing subtle changes - not so subtle on the deck where shadows and actual movement, but ignore that. The sky shows subtle changes between the two pairs, possibly related to clouds - very diffuse clouds - passing overhead. They have a radiometer to look for differences in illumination because it affects the heat flow, and those differences would include time of day, tau and cloud shadows.

The sky shows subtle changes between the two pairs, possibly related to clouds - very diffuse clouds - passing overhead. Some of the differences may be due to the onboard jpeg compression. Since the insight "raw" site is providing png's, that hopefully means that they are lossless relative to the received images - it wouldn't make sense to re-jpeg the received images and then convert those to pngs. I haven't heard anything about the original true raw images (ie, before onboard jpeg compression) eventually being sent home. |
