MIA009: Tubular Features



Mars Report Ref: MIA009

Report Date: July-August 2017

Research Status: Open - Possible construction/technology

Description: Tubular Features
Approximate size:  1.5 km

Mission image/date: MGS January 2000

Pixel width: 4.34 m
Location: Aram Chaos

Found by: J. P. Skipper

Graphics/image editing: M. J. Craig

Image source: See image captions


When first discovered by J.P. Skipper, this feature was presented as a possible example of artificial pipes spewing liquid. The low pixel size however will limit the possibility of that determination.

What is for certain, is that the area to the north and north-west, shows several lighter variations of the dark shapes and linear striations that make up the tubular features and the 'spray', strongly indicating their origin is one and the same (See MIA009.3).

This suggests that the 'tubes or pipes' are either newer formations, or that reflections of light and shadow play is responsible for their prominent appearance in the image.


Two tube-like formations each over 1 km in length, suggesting artificial constructions, with one of them possibly gushing liquid/spray.


Ground level illusions caused by reflective light and shadows. Misinterpretation of geological features.
