maybe we should start leaving evidence of ourselves, maybe carving into rocks or placing rocks in geometric patterns.

Simple... the algorithm software on the Rovers that edits out any thing of interest is not perfect and it misses the small stuff. Already covered that and linked to that in numerous threads
Had you looked further you will see I linked to ALL the images of the things people have called 'tubes' with all the source data.
Seems to me this is a really good find. Now I have not yet had time to pull the originals to confirm this but since all the originals are linked at Skippers site, it won't take long and I am sure ArMaP will help

Well, sorry you seem to think I was "baiting"....not intention, I assure you.
My mistake was in NOT referencing the exact image that I felt was posted in a way that somewhat misrepresented it....at least, the context could lead people astray. I see (after peering into its link info) that it IS described as a "painting" and is from the livingmoon site:

NO, sarcasm aside, there likely aren't "many" who would call them "sand dunes"....a few maybe....., but there's often a bad nut in every can.
Like I've said earlier....being a big fan of Science Fiction and all, it sure is fun to speculate, imagine and otherwise fool around with ideas --- but it seems to be a disservice to some who may be a bit, ermmmm, impressionable (naive?) who may not realize that fiction isn't always fact.......

Sorry, forgot about the source.
At 60 centimetres per pixel, that feature would be some 42 metres long.

If that algorithm exists and has any practical use.
Dr. Andrew E. Johnson graduated with Highest Distinction from the University of Kansas in 1991 with a BS in Engineering Physics and a BS in Mathematics. In 1997, he received his Ph.D. from the Robotics Institute at Carnegie Mellon University where he developed the spin-image surface signature for object recognition and surface matching. Currently, he is a Principal Member of Technical Staff at the Jet Propulsion Laboratory where he is developing image-based techniques for autonomous navigation and mapping during descent to planets moons, comets and asteroids. At JPL, Dr. Johnson has worked on technology development tasks as well as flight projects. For the Mars Exploration Rover Project, Dr. Johnson was the lead algorithm developer for the Descent Image Motion Estimation Subsystem (DIMES), the first autonomous machine vision system used during planetary landing. Following the successful development and execution of DIMES, he is now moving back to the development of machine vision systems for landing hazard avoidance, pin-point landing and rover navigation. Part of this work includes a collaboration with the University of Southern California and the University of Minnesota in the area of vision guided safe and precise landing for autonomous helicopters. In 2003, Dr. Johnson was awarded the JPL Lew Allen Award for Excellence for his "groundbreaking contributions in the area of machine vision algorithms for safe and precise landing."
AbstractSpace tugs must be able to search for and identify inert non-communicative targets, whose ephemeris is only known approximately. The goal of this article is to evaluate the efciency of three possible two-dimensional search strategies in the context of autonomous rendezvous in space. As part of a broader Space Tug project, a number of modeling challenges were addressed to validate the experimental results.
The author models the autonomous process in which an agent, a robot or a software algorithm searching for information in a computer database, searches the space around its current location for desired information. The search area is divided in a set of locations (x, y), dened in Cartesian coordinates. Associated with each location is a probability q(x, y) representing the likelihood of nding the information wanted at this location. Assuming the environment is static, the space can thus be described as a probability space. The agent, which in the context of this project is the tug, always moves in the direction where the probability q(x, y) is the greatest. Once the agent moves to the new location - from (x0, y0) to (xnew, ynew) -, the probability q(xnew, ynew) of nding information at the new point is updated depending on what was found.
PREVIOUS WORK We looked at several references devoted to Mars rovers due to the similar autonomy and energy requirements and constraints of their missions.
