This Mars Optical Illusion Is Tripping Me Out: Pit or Plateau?

Tech News

This tale is section of Welcome to Mars, our series checking out the purple world.

Whoa, dude. My eyes and brain are facing a entertaining challenge with an picture from NASA’s Mars Reconnaissance Orbiter spacecraft. The HiRise digicam staff at the College of Arizona shared a check out on Monday of a landscape in the Ceraunius Fossae space of the purple planet. I’m owning problems processing the simple fact that the highlighted element goes down, not up. 

The HiRise workforce reported we’re hunting at “an elongated collapse pit.” My brain is observing it as a plateau many thanks to the angle and path of the lights. It appears to me like a raised scar or a giant place slug. With some hard work and focus, I can get the picture to seem like a pit, but it inevitably flips back again. 

If you conveniently see this as an indentation, then you are most likely asking yourself what I am likely on about. But if you happen to be like me and have a tendency to see raised locations as a substitute of pits in views like this, then you can test the trick of flipping the graphic around to see if reorienting the shadow delivers it into aim. This is effective perfectly for me.

Is this any much better? Here is the HiRise watch of a collapse pit turned upside-down.


HiRise has a superior see of the floor, but that sales opportunities to some queries as to what may be going on out of sight. “This observation can aid to explain to irrespective of whether or not there is a subterranean connection to this pit,” reported the group. “As an added reward, the considerably smaller despair to its south also seems to be an additional collapse pit.”   

If you like this Martian pit, then you may really like these:

Pits on Mars are fascinating and deserving of deeper examine. Researchers suspect Mars is hiding some volcanic caves, which could be locations for potential exploration by robots or human website visitors hunting for signals of historic life or a sheltered put to camp out on an unfriendly planet.
