NASA’s Curiosity Rover May Have Found Fossils on Mars
For years, theorists have suggested that Mars once contained the necessary requirements to support life. Now, NASA’s Curiosity rover may have finally found indication of this from images showing what appear to be fossilized microbial structures.
Over the past five and a half years, NASA’s Curiosity rover has been mapping and imaging the Martian surface to gain more insight on the dusty planet. In addition to snapping pictures, the nomadic vehicle has been searching for signs of water, while also determining the viability for human colonization.
Scientists know that water once flowed on Mars and have been on a quest to discover whether it still does to this day. Aside from ice caps on the Martian poles, evidence of water in Mars’ past can be seen in dried lake beds, gullies, and what was once a large ocean in the planet’s topography.
In recent images of the Gillespie Lake outcrop, in the Yellowknife Bay area, Curiosity sent back pictures of small stick-like formations in a segment of sedimentary rock. To the untrained eye these formations might not appear to be much, but to a microbiologist who has studied microbially induced sedimentary structures (MISS), the pictures seem to have some profound implications.
Nora Noffke of Old Dominion University in Virgina meticulously compared the photo to instances of MISS on Earth and published a paper that has intrigued scientists at NASA. Though she’s hesitant to make any definitive claims, her paper provides some of the best evidence to date for indications of past lifeforms.
The stick-shaped markings aren’t actually considered to be fossils of microorganisms themselves, but rather fossils of their imprints.
Some have contested that these tubular markings are more likely crystals, rather than the footprint of microorganisms. In either case, the finding shows that the area once consisted of a body of water that had the elements needed to support life.
NASA is planning on sending another rover to Mars in 2020 that is nearly identical to Curiosity, with the goal of strictly searching for signs of previous life. Once collected, samples will be sent back to Earth from a small rocket deployed from the rover.
Scientists have recently found other signs of life on the red planet, including fluctuating levels of methane in the atmosphere. Some have proposed the idea that this gas may be coming from life below the surface.
On Earth, methane is produced from bacteria, primarily in the stomachs of animals and humans. Could there be bacteria, or life containing bacteria, producing that methane below the Martian surface?

Alleged Volcanic Eruption on Mars Sparks NASA Cover-Up Conspiracy
Conspiracy and speculation erupted across the internet yesterday over an alleged volcanic plume stretching roughly 1,200 miles across the Martian atmosphere. The plume appears to originate from the planet’s supposedly dormant Arsia Mons volcano.
Images of the activity were taken on Sept. 24 by the Mars Express orbiter and later published by the European Space Agency.
According to NASA, volcanic activity on the red planet ceased some 50 million years ago after Earth’s Cretaceous-Paleogene event that killed off the dinosaurs, but some believe this latest imaging shows otherwise.
Spurred by conjecture from a popular YouTube conspiracy channel, claims of volcanic activity on Mars reignited theories of government cover-ups and strange happenings within NASA, the FBI and other controversial government agencies.
Many are pointing to last month’s Sunspot National Observatory shutdown, the switch to a limited “safe mode” on the Hubble and Chandra telescopes, and the sudden failure of NASA’s Mars Curiosity Rover as evidence that strange events occurring on the planet may be intentionally obfuscated.
Arsia Mons is located within a tightly situated line of volcanoes on Mars, collectively known as Tharsis Montes, which lie in the shadow of Olympus Mons – the largest volcano in our solar system (more than twice the size of Mt. Everest).
Arsia Mons happens to be the planet’s second largest volcano in terms of volume and is home to a series of caves NASA has studied as the best places to situate research and habitation modules. Could there be something already underway?
“This project developed a revolutionary system to exploit the novel idea of extraterrestrial cave use” stated a project summary published in 2004, further explaining that two “missions” were tested to gather data.
Arsia Mons is known to have an annual whether phenomenon in which sunlight warms the area around the volcano, bringing small amounts of dust into the air. Rising air currents bring this dust and other fine sediment above the volcano’s caldera into a thick, spiraling cloud that is big enough to be seen by a probe orbiting the planet.
But the latest plume looks nothing like the spiraling cloud recorded from this phenomenon in the past. Instead it appears as more of a streaking trail that’s persisted over the course of weeks.
NASA has attributed the plume to water ice clouds that are gathering over the volcano. The agency says that at certain times of year, the small amounts of water in the atmosphere freeze and condense near areas of high altitude, notably above this volcanic region.
If this is the case, then maybe there’s significantly more water on the red planet than previously believed and we should study the areas it’s sublimating from.
But then again, there’s always some simple explanation from NASA that seems to make everyone’s concerns seem trivial. Is this really just a storm or are they covering up something far greater?
