Possible ‘Portal’ to Alien Life Discovered on Mars: NASA Investigates Enormous Martian Hole
NASA has acknowledged that a massive, 300-foot-wide opening on the surface of Mars could potentially be a ‘portal’ to a subterranean realm where alien life might exist. The space agency unveiled a striking image of this significant cavity in the Martian terrain on Sunday as its Astronomy Picture of the Day, sparking intrigue and speculation about what lies beneath the Red Planet’s surface.

NASA Scientists Explore Potential of Underground Caves for Martian Life
Instead of leaving the public to ponder the mystery, NASA proposed that this immense hole appears to descend to a mysterious ‘lower level’ that could conceivably harbor life. “Depressions such as this are particularly captivating due to the possibility they represent entrances to lower regions that extend into vast underground caverns,” NASA researchers stated. “If such a connection exists, these naturally formed tunnels offer a degree of protection from the severe Martian surface conditions, making them relatively favorable locations to potentially find Martian life,” they added.
This statement marks a notable point from NASA, an organization that has historically sought to moderate public anticipation regarding the discovery of extraterrestrial life, both on other planets and Earth’s own celestial neighbors. The prevailing focus has been on the search for microbial organisms that could be concealed within frozen oceans on other planetary bodies and moons within our solar system.
Underground Caves on Mars: A Prime Target for Future Missions
However, researchers highlighted the prospect of ‘expansive underground caves’ beyond this newly discovered hole, suggesting that this region could emerge as a key destination for forthcoming astronaut missions to Mars. This subsurface environment offers a refuge from the harsh radiation impacting the Martian surface.

NASA released an image of a massive hole on Mars, part of the Astronomy Picture of the Day series.
Swiss Cheese Terrain: Multiple Holes Identified on Mars
NASA clarified that the image, initially captured in 2017 by the Mars Reconnaissance Orbiter, reveals numerous openings across the planet’s landscape. “There are several holes visible in this ‘Swiss cheese-like’ terrain, with the majority displaying a dusty, dark, Martian surface underneath evaporating, light, carbon dioxide ice,” the researchers explained.
The most prominent cavity is the perfectly circular hole visible in the upper-right section of the satellite image – a substantial void approximately 328 feet in diameter.
Mystery Surrounds Martian Hole’s Formation and Potential Contents
Adding to the enigma is the presence of a circular impact crater surrounding this particular hole. While the NASA team speculated that a meteor impact could be responsible for its creation, the more pressing question revolves around what may reside at the depths of this pit. “These pits are, therefore, also highly attractive targets for potential future spacecraft, robots, and even human interplanetary explorers,” NASA further commented, emphasizing the scientific importance of these features.
Subterranean Martian Caves: A Haven for Potential Life?
Although scientists hypothesize that Mars was once more Earth-like billions of years ago, the most promising avenue for uncovering evidence of present-day life lies in the potential for NASA’s rovers, satellites, and future astronauts to locate underground caves or lava tubes within the ancient Martian crust. The current Martian environment, lacking a significant magnetic field and dense atmosphere, exposes the surface to elevated levels of cosmic and solar radiation, detrimental to life as we understand it.
Mars may contain numerous holes from meteor impacts, potentially leading to extensive underground cave systems.
The USGS Astrogeology Science Center has mapped potential entry points to subterranean Martian caves.
USGS Mapping Efforts Target Cave Entrances on Mars
However, life might have persisted beneath the surface, benefiting from the natural protection offered by these caves and tubes. This suggests that astronauts could potentially discover signs, or even fossils, of living organisms in these shielded locations.
The US Geological Survey (USGS), specialists in underground geological features, has been involved in the search for these Martian caves. In 2019, the USGS Astrogeology Science Center unveiled a detailed map identifying over 1,000 possible candidates believed to be cave entrances distributed across the Martian surface.
Nevertheless, the USGS noted that their analysis relied on data gathered by probes orbiting approximately 250 miles above the Mars surface.
Glen Cushing, a space scientist from the USGS Astrogeology Science Center, explained, “It is impossible to determine the extent of these features beneath the surface.” He further added in the 2019 announcement, “Lacking definitive knowledge of whether these are true caves or simply alcoves with limited horizontal extent, we cautiously refer to them as ‘candidate’ cave entrances.”
Evidence of Subterranean Layers Confirmed by New Image
Other space programs, including the European Space Agency’s Mars Express mission, have also detected indications of ancient lava tubes beneath the planet’s extinct volcanoes. Yet, this recently released image definitively illustrates the presence of at least one hole on Mars that connects to an unexplored subterranean stratum.
Human Exploration of Mars and Subterranean Caves on the Horizon
SpaceX Aims for Crewed Mars Mission Sooner Than Expected
Human astronauts could potentially explore this colossal opening as early as 2028. SpaceX founder Elon Musk recently indicated on the Joe Rogan Experience podcast a more accelerated timeline for human arrival on the Red Planet.
The previous objective was to land the first astronauts on Mars no earlier than 2030. Musk announced that SpaceX’s ‘default plan’ is to ‘launch several Starships to Mars at the end of next year.’ These are the same advanced spacecraft SpaceX has been rigorously testing, albeit with some tests culminating in dramatic explosions.
These initial missions would be uncrewed and designed to evaluate the Starships’ landing capabilities on the Red Planet. Musk conveyed his aspiration for SpaceX to launch a total of five of these remotely operated starships to Mars in 2026, paving the way for human exploration of the Martian subsurface and the search for potential alien life.
