In the quiet expanse of our solar system, a red jewel glows with an inviting yet mysterious allure. It is Mars, our planetary neighbor, whose canyons and river valleys have for centuries been fuel for imaginations and wonderings about life beyond our home. We’ve affectionately dubbed it the Red Planet, but a new moniker is taking hold as our probes and rovers send back tantalizing data: The Real Martians.

Our story begins with a simple question that has spurred countless missions and mobilized teams of scientists: Could there be life on Mars? Dr. Eleanor Langston, an astrobiologist at the European Space Research Institute, paints the picture: “Mars has been intriguing to us not just because of its proximity, but because of its history. It’s like Earth’s sibling that took a different path. We know it had liquid water, and where there’s water, the potential for life as we know it increases exponentially.”

In 1976, the Viking Landers touched Martian soil, making history as the first mission to successfully land on Mars and perform experiments directly aimed at detecting life. They searched for signs of microbial metabolism in the Martian soil, but the results were inconclusive. Some scientists saw the fingerprints of life in the data, while others chalked it up to unusual soil chemistry. Dr. Langston recalls, “The Viking missions were groundbreaking. They showed us that finding life wasn’t going to be easy, and they set the stage for the meticulous, step-by-step approach that characterizes Mars exploration today.”

Fast forward to the 21st century, and the hunt for Martian life has evolved into a multifaceted quest. Rovers like Spirit, Opportunity, and Curiosity have roamed the Martian surface, each more sophisticated than the last. They’re our eyes and hands on Mars, equipped with cameras, drills, and labs that can analyze soil and rock samples. These rovers have found evidence of ancient water flows and even organic molecules, the carbon-based building blocks of life. “Curiosity’s findings at Gale Crater provided strong evidence that Mars once had the right conditions to support microbial life,” explains Dr. James Lin, a planetary scientist at NASA. “It’s a detective story on a planetary scale.”

The most recent player in this cosmic detective story is Perseverance. Launched in 2020, Perseverance is tasked with a pivotal role: to search for signs of past life and collect samples that future missions could bring back to Earth. It landed in Jezero Crater, a site believed to have once hosted a lake. What makes Perseverance different, Dr. Lin tells us, is its capability to look for biosignatures, or signs of past life, in an environment where life could have existed.

Not to be left out of this story is the fleet of orbiters like Mars Reconnaissance Orbiter and MAVEN that scan the Martian surface and study its atmosphere from above. They’ve painted a detailed portrait of Mars’ climate and geology and detected trace amounts of methane, a gas that on Earth is largely produced by living organisms. “The periodic spikes of methane are one of the most tantalizing puzzles,” says Dr. Langston. “It could have a biological source, but we just don’t know yet. It’s like Mars is teasing us, urging us to look closer.”

While robots have been our Martian proxies thus far, the next chapter in this narrative may well include human explorers. Scientists like Dr. Langston are excited about what humans could achieve on Mars: “A human geologist could do in a few days what the rovers have taken years to accomplish,” she notes, “Humans bring adaptability and intuition to problem-solving that our current robots just can’t match.”

As we continue this interplanetary quest, we are also searching for ourselves, for understanding our place in the cosmos. What would it mean to discover life, even just microbial, on another planet? Dr. Langston pauses before responding: “It would be profound,” she says. “It would tell us that we are not alone, that life as a phenomenon is not unique to Earth. It could exist elsewhere in our solar system, in our galaxy, in the universe.”

We are at a thrilling juncture in the story of Mars. Each mission, from Viking to Perseverance, has been a chapter leading us towards an answer that feels almost within reach. Whether Mars holds the secret of past life or presents conditions where future life (perhaps an extension of Earth’s own biosphere via human colonization) could thrive, it’s clear that the Real Martians, whether past, present, or future, are central to the next era of space exploration.

As we peer through the lenses of our rovers, sift through the data they send back, and plan for the day when human boots might step onto that red soil, we are doing more than exploring a planet. We are seeking kinship with a world that has captivated our collective imagination for generations. In the grand tale of Mars, we are the eager readers, the dedicated scribes, and, perhaps soon, the vibrant characters in an unfolding chapter of cosmic proportions.


  • expanse: A wide and open area of space, land, or water.
  • astrobiologist: A scientist who studies life in the universe, including life on Earth and the potential for life elsewhere.
  • microbial: Relating to or characteristic of microorganisms, especially bacteria and other tiny life forms.
  • inconclusive: Not leading to a firm conclusion or result; not ending doubt or dispute.
  • multifaceted: Having many different aspects or features; diverse and complex.
  • biosignatures: Signs or indicators of past or present life, based on measurable attributes or patterns that are produced by living organisms.
  • methane: A colorless, odorless gas that is used as a fuel and is produced naturally by decomposing plant material and digestive processes of animals.
  • tantalizing: Teasing or tormenting by exciting hopes or desires and then disappointing them; enticing.
  • proxies: A person or thing that is acting or used in place of another; a substitute.
  • kinship: A sharing of characteristics or origins; a close connection.

Key Takeaways:

  • Mars has captivated human interest due to its potential to have hosted life, driven by evidence of liquid water in its past.
  • Since the Viking Landers in 1976, various Mars missions have aimed to detect signs of life, with results that have intrigued but not confirmed the existence of life.
  • Modern rovers like Curiosity and Perseverance have sophisticated tools for analyzing Martian soil and rocks for signs of past life and have found organic molecules and evidence of ancient water flows.
  • Perseverance, the most recent rover, is tasked with searching for signs of past life in Jezero Crater and collecting samples for potential future return to Earth.
  • Orbiters studying Mars from above have provided detailed data on the planet’s climate and geology and have detected trace amounts of methane, whose source remains a puzzle.
  • Human exploration of Mars could significantly accelerate the search for signs of life and understanding of the planet’s geology.
  • Discovering life on Mars, even microbial, would have profound implications, suggesting that life as a phenomenon may not be unique to Earth.
