“My name is Josh Zeffren and I am one of the interns working with ALFA on the Agnostic Life Finder. It has been my pleasure to join this incredible team working on ALF; being a part of this organization means I can use my expertise in chemical engineering and my curiosity about the universe to make something that will grow the knowledge of mankind. During my time in the lab, I have worked with several iterations of our electrodialysis tool. I’m constantly working to improve the design, test ALF’s DNA separation capabilities, look for new ways to improve, and fix any mechanical issues we face. As one of our CAD specialists, I also work to produce new parts and new designs to keep improving ALF every day. Over the course of my time on this team, I have played many roles, each of them a valuable learning opportunity for me. I have been an engineer, a lab technician, an advocate, a CAD specialist, and now a teacher for our newest team members. It would be a dream come true to see ALF one day leave Earth and visit where no man has gone before. I believe it is crucial that we learn as much as we can about Mars before we arrive, and that goes double for possible signs of life. Thank you to everyone that supports this work; I look forward to sharing it with the world.”–Josh Zeffren

The lunar occultation of Mars is a captivating astronomical event that offers both scientific value and visual spectacle. This phenomenon occurs when the Moon passes directly in front of Mars, temporarily hiding it from view. Lunar occultations of Mars are relatively rare, happening only when the Moon's orbit aligns perfectly with Mars' position in the sky. These events provide astronomers with unique opportunities to study Mars' atmosphere and surface features as the planet gradually disappears and reappears behind the Moon's limb (visible edge of the Moon seen from Earth). These events also serve as natural timekeepers, allowing for precise measurements of the Moon's position and motion. Such data contributes to our understanding of lunar dynamics and helps refine our models of the Earth-Moon system. For ALFA Mars, lunar occultations represent the kind of precise astronomical alignments that inspire our mission. Just as the Moon reveals Mars' secrets during an occultation, our instruments aim to uncover the hidden potential for life on the Red Planet, peering beneath its surface to detect possible indicators of life.

Terrestrial soils and Martian regolith, while both crucial for potential life, have distinct characteristics that reflect their vastly different environments. Earth's soils are teeming with life, containing diverse microorganisms, organic matter, and nutrients. They form through complex weathering processes, biological activity, and interactions with water and air. Our soils support a wide range of ecosystems and are essential for agriculture. In contrast, Martian regolith is sterile and lacks organic content. It's primarily composed of fine, iron-rich particles formed by physical weathering and meteor impacts. The regolith contains perchlorates, which are toxic to most Earth life forms. Unlike Earth's soils, Martian regolith doesn't benefit from the constant recycling of nutrients through biological processes. However, both Earth soils and Martian regolith play crucial roles in their respective planetary systems. Earth's soils act as a carbon sink and water reservoir, while Martian regolith could potentially harbor subsurface water ice and provide valuable resources for future human missions. Understanding these differences is vital for ALFA Mars' mission to search for life on the Red Planet. #MarsVsEarth #ALFAMars #MarsExploration

The Mars Reconnaissance Orbiter (MRO) and its Mars Climate Sounder (MCS) instrument have revolutionized our understanding of the Red Planet's atmosphere and climate. MCS is a sophisticated radiometer that observes Mars' atmosphere across nine spectral channels in the visible and infrared wavelengths. It takes vertical profile measurements every 5 km, from the surface up to an altitude of 80 km, capturing critical data on temperature, pressure, water vapor, and dust content. These observations are compiled into daily, three-dimensional global weather maps for both day and night, providing unprecedented insights into Martian meteorology. The data collected by MCS has been crucial in understanding Mars' atmospheric dynamics, water cycle, and dust storms, revealing the exchange of water between the surface and atmosphere and contributing to our knowledge of the Martian hydrologic cycle. Since its launch in 2006, MCS has operated continuously, creating a long-term climate record that enables scientists to study seasonal and interannual variations in Mars' weather patterns. This wealth of data is vital for future Mars exploration missions and our quest to unravel the planet's past and present habitability. #MarsOrbiterSeries #ALFAMars #MarsExploration

Mars Express, the European Space Agency's pioneering mission to Mars, has significantly enhanced our understanding of the Red Planet since its arrival in 2003. This versatile orbiter is equipped with a range of advanced instruments, including high-resolution cameras, spectrometers, and radar systems, enabling it to investigate Mars' geology, atmosphere, and the potential for past or present life. Among its key achievements, Mars Express has detected methane in the Martian atmosphere, suggesting possible biological or geological activity. It has mapped the composition of the polar ice caps, revealing a mixture of water and carbon dioxide ice. Additionally, the orbiter discovered a potential subsurface water deposit beneath Mars' south pole using its MARSIS radar. It has also captured stunning high-resolution images of the Martian surface, helping to debunk the myth of the "face on Mars." After nearly two decades of operation, Mars Express continues to provide valuable data to support future Mars exploration missions. Its longevity and scientific contributions have established it as a cornerstone in our ongoing quest to unravel the mysteries of the Red Planet.

Celebrating Thanksgiving on Earth while the Curiosity rover explores Mars reminds us to be grateful for our planet and the wonders beyond. At ALFA Mars we give thanks for the science and our team that connects us to the cosmos! This image was created using an AI tool.

“My journey with ALFA Mars began inspired by The Martian, envisioning life on Mars. Now, as a Soil, Water, and Ecosystem Sciences major with a minor in Engineering Innovation, I contribute design precision to the ALFA team. Proficient in CAD software like SolidWorks and Fusion 360, I focus on CNC cutting and testing components for the Agnostic Life Finder (ALF), ensuring each part is mission-ready. Working with ALFA is more than technical tasks; it’s a learning experience that deepens my understanding of astrobiology. Mentorship from project leads like Jan Špaček has been invaluable, revealing the intersection of engineering and scientific inquiry. I take pride in building ALF components and analyzing data to support our mission. This role offers hands-on experience with profound questions in astrobiology, bringing me closer to understanding Mars' mysteries. Being part of ALFA fuels my passion for planetary science, connecting me to a project that could redefine our view of life in the universe. It’s thrilling to know my work contributes to a mission that may shift humanity’s understanding of our place in the cosmos.”–Izabelle Young #ALFAVolunteerStories #ALFAMars

Mars Global Surveyor (MGS) has been a game-changer in our understanding of the Red Planet, as well as the first successful mission to Mars since the Viking landers! Launched on 11/7/1996, MGS provided detailed maps of Mars’ surface, revealing its topography and geological features. This helped scientists piece together the planet’s history and surface processes, offering a clearer picture of Mars’ past. One of MGS’s groundbreaking discoveries was the detection of remnant magnetism in the Martian crust. This indicated that Mars once had a global magnetic field, which expanded our understanding of the planet’s geological history and its potential for habitability. The presence of a magnetic field in the past suggests that Mars might have been more Earth-like, with a thicker atmosphere and possibly liquid water on its surface. Thanks to MGS, we have a much deeper understanding of Mars’ geology, climate, and potential for life. Its contributions have laid the groundwork for future exploration and the ongoing search for extant life on the Red Planet.
