TL;DR

This paper reanalyzes Viking Labeled Release experiment data from Mars, proposing that the observed metabolic-like activity—originally dismissed as non-biological—represents evidence of extant life. Based on reinterpretation of soil chemistry and gas release patterns, the author argues for the existence of a new biological kingdom, Jakobia, within a distinct biosphere on Mars, with the findings grounded in long-standing data reevaluated in light of new insights into Martian environmental conditions.

ABSTRACT

Gillevinia straata, the scientific name [1, 2] recognizing the first extraterrestrial living form ever nomenclated, as well as the existence of a new biological kingdom, Jakobia, in a new biosphere -Marciana- of what now has become the living system Solaria, is grounded on old evidence reinterpreted in the light of newly acquired facts. The present exposition provides a summary overview of all these grounds, outlined here as follows. A more detailed paper is being prepared for publication.

Motivation & Objective

• To reevaluate the Viking Labeled Release experiment results in light of new understanding of Martian soil chemistry and environmental conditions.
• To argue that the observed gas release patterns from Martian soil are consistent with biological metabolism rather than abiotic processes.
• To propose the existence of a new biological kingdom, Jakobia, and a distinct biosphere—Marciana—on Mars.
• To provide a scientific basis for recognizing Gillevinia straata as the first formally nomenclated extraterrestrial life form.
• To present a comprehensive reinterpretation of historical data to support the hypothesis of extant life on Mars.

Proposed method

• Reanalysis of gas release data from the Viking Labeled Release experiment, focusing on the timing and magnitude of CO2 release from Martian soil.
• Application of biological response models to interpret the observed metabolic-like activity in the context of terrestrial analogs.
• Use of environmental data from the Viking landers to assess the plausibility of liquid water and microbial activity in the soil.
• Incorporation of new insights into soil chemistry, including the role of perchlorates and their reactivity under UV exposure.
• Comparison of the observed responses with known abiotic chemical reactions to rule out non-biological explanations.
• Use of a revised interpretation of the 1976 experiment to support the existence of a new biosphere and biological kingdom on Mars.

Experimental results

Research questions

• RQ1 Does the gas release observed in the Viking Labeled Release experiment exhibit characteristics consistent with biological metabolism?
• RQ2 Can the observed responses in Martian soil be explained by abiotic chemical processes alone?
• RQ3 What evidence supports the existence of a distinct biosphere on Mars, separate from Earth's?
• RQ4 Is there sufficient basis to formally name an extraterrestrial life form, such as Gillevinia straata?
• RQ5 How do newly acquired insights into Martian soil chemistry affect the interpretation of the Viking data?

Key findings

• The gas release patterns observed in the Viking Labeled Release experiment are consistent with biological metabolism, not abiotic reactions.
• The detection of a soil level tilt after the experiment suggests the presence of a liquid-like phase, precluding the possibility of dry, non-liquid conditions.
• The data support the existence of a new biological kingdom, Jakobia, within a distinct biosphere on Mars, named Marciana.
• The author proposes that Gillevinia straata is the first formally nomenclated extraterrestrial life form.
• The reinterpretation of the Viking data, informed by new environmental data, strengthens the case for extant life on Mars.
• The study concludes that the original Viking results, when reevaluated, provide compelling evidence for life on Mars.
