This statement was meant to look at a pit recognized in a Context Digicam picture to see if HiRISE might resolve any particulars inside.
On this cutout, we see the “regular” view of the HiRISE picture on the left, whereas the proper exhibits what occurs after we attempt to “improve” the brightness of the pixels within the pit.
Thankfully, HiRISE is delicate sufficient to really see issues on this in any other case darkish pit. Since HiRISE turned by nearly 30 levels to seize this picture, we are able to see the tough japanese wall of the pit. The ground of the pit seems to be clean sand and slopes right down to the southeast. The hope was to find out if this was an remoted pit, or if it was a skylight right into a tunnel, very like skylights within the lava tubes of Hawai’i. We won’t clearly see any tunnels within the seen partitions, however they may very well be within the different partitions that are not seen.
