Mars, the fourth planet of our solar system, is our nearest neighbor. The quiet red planet has been visited by numerous automated missions, such as the Viking probes and the Curiosity Rover.
Across the numerous automated missions sent by NASA, one question has been on the mind of people back on Earth: could there be Mars aliens hiding on the red planet?
The Mars surface has been scanned by NASA probes for decades. One fascinating feature, discovered in 2011 by the Mars Reconnaissance Orbiter, is a perfectly round hole surrounded by a crater.
“Why there is a circular crater surrounding this hole remains a topic of speculation, as is the full extent of the underlying cavern,” NASA remarked about the image.
“Holes such as this are of particular interest because their interior caves are relatively protected from the harsh surface of Mars, making them relatively good candidates to contain Martian life.”
As such, the hole is a likely candidate for future Martian missions. As the image suggests a possible cavern or cave network beneath the surface, the imagination runs wild the possibilities of what could be lurking there.
Mars is very unlike our Earth. The atmosphere has no oxygen, and the soil does not seem to harbor any life forms. Research by scouting probes has not turned up any evidence of microbiology. Orbiting satellites have noted no trees, flowers or shrubs on the surface. To all accounts, Mars looks like a dead planet.
However, it might not have always been this way. Some geological features on the rocky red planet could have been carved out by liquid water millions of years ago. If ever there was water on Mars, maybe it is now frozen beneath the planets polar ice caps.
Why is this important? The presence of liquid water on the planet’s surface in the distant past could suggest a planet habitable by life as we understand it. Such life may have even left behind evidence of their existence. Perhaps, such evidence would be preserved beneath the surface.
The hole on the surface of Mars could be little more than another natural geological formation. However, NASA thinks it could house evidence of life forms that may have once called Mars home. If such creatures ever left behind evidence of their existence, surely they would be beneath the dunes, safe from the harsh sun and constant winds of Mars.
