On 10 February 2008 NASA released this image (PSP_007230_2170) taken by the Mars Reconnaissance Orbiter HiRISE camera.
Looking at the complete image you will note not just the massive dome but also many, destroyed and half buried “glass tubes” in the Martian soil (click on the image below for a larger view).
Case #3: Massive dome in crater on Mars:
Many may argue that this is not a dome but rather the bottom of the crater that was filled with water and later dried up and left a wavy pattern in the Martian soil.
This may seem plausible, however NASA’s description of the image states: “Crater with Textured Mound in Central Acidalia Planitia” inferring it is actually a spherical, dome-like object casting a shadow on the crater wall.
A similar dome was built at the Amundsen-Scott South Pole Station, but was dismantled in January 2010.

Is this another Amundsen-Scott South Pole Station dome-type structure on Mars?
