Recently, a small pit on the flank of an ancient volcano on Mars has sparked curiosity among scientists. Initially imaged by NASA’s Mars Reconnaissance Orbiter, this pit could hold significant clues about the Red Planet’s geology.

Situated on the extinct volcano Arsia Mons, the pit is part of a series found on the flanks of volcanoes in the Tharsis region of Mars. It appears to be a vertical shaft, prompting speculation about its origin and composition.
Pits and caves on Mars are of particular interest due to their potential to provide shelter for future astronauts. Mars’ thin atmosphere offers little protection from radiation, making underground structures essential for human habitation.
Beyond shelter, these pits could harbour traces of ancient Martian life. The presence of underground caves may have once provided a suitable environment for microbial organisms to thrive, offering valuable insights into Mars’ past habitability.
The formation of these pits is likely linked to volcanic activity on Mars. Lava channels underground, formed during volcanic eruptions, may have left behind empty tubes that eventually collapsed to create the observed pits.
Planetary scientists are intrigued by the nature of these pits, exploring various hypotheses about their formation. From collapsed lava tubes to tectonic stresses, multiple factors could contribute to their creation.
Similar geological features, such as karsts on Earth, offer insights into the potential formation processes of Martian pits. Understanding these parallels may shed light on Mars’ geological history.
While rover missions provide valuable data, airborne missions like NASA’s Ingenuity helicopter could offer new perspectives by hovering over and descending into these pits. Exploring these underground structures may be crucial for future manned missions to Mars.
