Exploring Martian Agriculture: Unveiling the Potential of Fly Larvae and Synthetic Soil for Veggie Growth

In the quest to conquer the challenges of sustenance on Mars, aerospace engineering undergraduate Emmanuel Mendoza has taken a unique approach: cultivating veggies in simulated Martian soil enriched with an unusual ingredient—fly larvae poop. While humans have left their footprints on the moon, the red planet remains an unexplored frontier, and the hurdle of providing adequate food for a Mars-bound crew looms large.

Mendoza, currently conducting a groundbreaking study at Texas A&M University, delves into the intricacies of Martian agriculture. Inspired by Ridley Scott's cinematic depiction in "The Martian," where a stranded botanist resorts to growing potatoes on Mars, Mendoza seeks to unravel the mysteries of Martian soil. "What modifications— if any— can we make to the soil in the future to, you know, make it more habitable for terrestrial plant growth on a different planet," he pondered in a conversation with NPR. The goal? Extraterrestrial plant growth.

At the Forensic Laboratory for Investigative Entomological Sciences (FLIES), Mendoza's experiment involves growing English peas in simulated Martian soil blended with fly larvae excrement. The Martian soil, carefully manufactured on Earth using data from Martian landers, comes with a hefty price tag, restricting the variety of plants suitable for cultivation. While potatoes, akin to Mark Watney's survival strategy in "The Martian," were considered, budgetary constraints and data accessibility led Mendoza to opt for English peas.

The choice of English peas is strategic; their self-pollinating nature allows Mendoza to collect real-time data on growth, a luxury denied when dealing with underground crops like potatoes. Martian soil, known as regolith, poses challenges with its rocky, coarse texture and a deficiency in essential organic matter. Mendoza's experiment aims to unlock the potential of this inhospitable soil by discovering the ideal combination that fosters plant growth, offering a glimpse into the feasibility of sustainable agriculture on Mars. As humanity contemplates a future beyond Earth, Mendoza's pioneering research may hold the key to turning Martian soil into a fertile home for crops destined for worlds beyond our own.

"Indeed, it's obviously missing the natural biota of any soil you'll find on Earth," remarks Emmanuel Mendoza, the pioneering mind behind a groundbreaking experiment seeking to unlock the secrets of Martian agriculture. As an aerospace engineering undergraduate at Texas A&M University, Mendoza faces the challenge of Martian soil, deficient in certain macronutrients crucial for plant growth, including nitrogen, phosphorus, and sulfur. Yet, it holds an intriguing balance, possessing elements essential for plant development while lacking additives that arise from prolonged exposure to life.

Enter the black soldier fly larvae, a seemingly unconventional solution to Martian soil limitations. These industrious larvae produce frass—a powdery waste rich in essential nutrients and organic matter. Mendoza harnesses the potential of these larvae to supplement his simulated Martian soil, turning waste into a valuable nutrient substitute. The experiment, now on the verge of completion, involved meticulously mixing different ratios of simulated soil and frass to determine the optimal blend for nurturing English pea plants.

Surprisingly, Mendoza observes growth across all plants, even those cultivated in 100% simulated Martian soil. The imminent harvest of pea pods marks the culmination of the experiment, where Mendoza will conduct thorough analyses of weight, measurements, and other vital data. The results, destined for a comprehensive paper, were recently presented at the Entomological Society of America's 2023 conference.

However, Mendoza envisions his role as a catalyst for further exploration rather than a conclusion. As he approaches the end of his junior year, he acknowledges the collaborative nature of scientific progress, expressing a desire to contribute to future studies led by more experienced researchers. While his experiment doesn't directly address Mars' water challenge, Mendoza envisions it as a potential avenue for future exploration.

In contemplating the prospect of venturing to Mars himself, Mendoza's aspirations extend beyond survival scenarios like Mark Watney's in "The Martian." Instead, he envisions becoming an archetype, inspiring others to maximize available resources for interplanetary habitation. As Mendoza looks forward to completing his junior year, his experiment stands as a testament to the innovative spirit propelling humanity toward a future where Martian agriculture might not be a distant dream.

In conclusion, Emmanuel Mendoza's pioneering experiment at Texas A&M University represents a significant leap toward understanding the complexities of cultivating crops on Mars. Faced with the challenges of Martian soil, Mendoza ingeniously turned to black soldier fly larvae to supplement the missing nutrients and organic matter crucial for plant growth. The results, showcased at the Entomological Society of America's 2023 conference, reveal promising signs of growth across all plants, even those in 100% simulated Martian soil.

As Mendoza nears the completion of his junior year, the imminent harvest of pea pods marks the culmination of this groundbreaking study. The meticulous analysis of weight, measurements, and other data will soon find its way into a comprehensive paper, contributing valuable insights to the realm of Martian agriculture.

Yet, Mendoza's vision extends beyond his current experiment. Rather than viewing this as a conclusion, he sees it as a catalyst for further research, expressing a desire to collaborate with seasoned researchers in future studies. While the experiment doesn't directly address the challenge of water on Mars, Mendoza hints at the potential for future investigations in that direction.

In contemplating the possibility of human travel to Mars, Mendoza envisions a role beyond mere survival scenarios. He aspires to be an archetype, inspiring others to make the most of available resources for interplanetary habitation. As the journey towards understanding Martian agriculture progresses, Mendoza's experiment stands as a testament to the innovative spirit and determination that fuel humanity's aspirations for a future where the cultivation of crops on Mars becomes a tangible reality.
