The images have comparable resolutions of 1.44 meters/pixel and 4.29 meters/pixel. The images are also clear and free from obscuring dust or clouds.
When the images were compared three New flows were discovered in the more recent image that had no counterpart in the older image. None of the older flows has noticeably changed. The three new flows are labeled A, B, and C in these pictures.
The lengths of the new flows found in M04/01228 are as follows:
Flow Name | Flow Length | Approximate Length in Meters | |
A | 11 pixels | 45 meters | |
B | 20 pixels | 84 meters | |
C | 32 pixels | 139 meters |
In comparison to the lengths of these three new flow features, the largest flow features in M04/01228 are approximately 890 meters long.
The following conclusions are drawn;
1. | Flows are "Long Lived" surface features that persist for more than 5 months. |
2. | Flows are very recent surface features forming at the present time on the Martian surface. |
3. | It seems obvious but it should be pointed out that new flow features appear very dark. Presumably they get lighter over time. Why they start out dark, why they get lighter, and what causes them to suddenly appear are questions that need to be answered. |
Compare all images in the MOC database searching for other overlapping images containing flow features. This will give additional data and help formulate conclusions about what the flows are made of and how they are forming.
In many other images, faded flow patterns are clearly visible next to darker newer flows. Flow features appear to fade with time. How much time it takes for a flow to fade is a very interesting question and that information could possibly be used to draw conclusions about the creation process and creation rate of the flow features. A possible hypothesis is that flow features will appear in a steady state with old flows fading at the same rate that new flows are being created.
Since flow features are persistent for periods of time longer than Martian seasons it is unlikely that there will be any seasonal correlation between imaging time and seasons. The exercise should still be done however.
Count the number of flows in each image and plot the count against latitude to see if there is a smooth decline in flows as you move away from the equator. Preliminary analysis from Efrain Palermo strongly suggests that this is true.
On the wish list, it would be nice to stand in the middle of a flow and sample it. This would instantly answer many questions.

Special thanks to Nasa/JPL/Malin Space Science Systems for their efforts in organizing and creating this data and most importantly making it's catalog and database available. Thank you so much, exploring Mars and making this discovery, whatever it may mean, has been an exciting and wonderful experience and is the closest I am every likely to get to exploring other worlds.
Thank you!
