Explanation: What created this unusual hole in Mars? Actually, there are numerous holes pictured in this Swiss cheese-like landscape, with all-but-one of them showing a dusty, dark, Martian terrain beneath evaporating, light, carbon dioxide ice. The most unusual hole is on the upper right, spans about 100 meters, and seems to punch through to a lower level. Why this hole exists and why it is surrounded by a circular crater remains a topic of speculation, although a leading hypothesis is that it was created by a meteor impact. Holes such as this are of particular interest because they might be portals to lower levels that extend into expansive underground caves. If so, these naturally occurring tunnels are relatively protected from the harsh surface of Mars, making them relatively good candidates to contain Martian life. These pits are therefore also prime targets for possible future spacecraft, robots, and even human interplanetary explorers.
But where’s Ziggy S.? Didn’t it get a picture of him, too?

It’s been orbiting Mars and snapping high resolution images for a while.
well it sounds like the mood has changed... sorry to bother.
? It’s no bother. The Mars Reconnaissance Orbiter has been doing its thing for 20 years, and has taken some stunning images of Mars. It’s really cool.
What?
