An Unusual Hole in Mars
apod.nasa.gov/apod/image/2504/…
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.

Als Antwort auf Josh Universe • • •The image depicts a close-up view of a textured surface, likely from a celestial body such as Mars. The surface is predominantly a uniform sandy brown color, with various shades indicating different elevations and textures. The surface features numerous small craters and pits, with some areas appearing smoother and others more rugged. The overall appearance is rough and uneven, with a circular frame highlighting the detailed texture. The background is black, emphasizing the surface's features.
