Another Broken Heart
image by " rel="nofollow John Moore, Ireland
Congratulations to John, who has figured out how to reconstruct the interleaved LRO Wide Angle Camera (WAC) " rel="nofollow files to create images. The LRO WAC image files are frustrating because they can not simply be looked since narrow image swaths are taken sequentially in 7 wavelengths, and then the adjacent piece of the image is acquired in 7 wavelengths, etc. This results in the WAC images looking like a venetian blind, with narrow swaths repeated 7 times before reaching the next geographic piece of the image. It should be an easy job to write software to re-assemble images, which the LRO team must have, but I am not aware of amateurs doing so before. John's experience differs from how I expected that image are unpacked and reassembled so more experimentation is in order. This wonderful image, which is uncalibrated, is a slightly lower illumination angle view than the extraordinary Apollo 15 Metric camera image. I expect that the two high resolution views can be used to create a very high resolution topographic map.

NOTE: I haven't checked recently the " rel="nofollow unmannedspaceraft.com forum - folks there are surely exploring WAC reconstructions.
