Abstract

Last year I presented a poster describing evidence of higher life forms in NASA/JPL rover photographs relayed to Earth from Mars. In this poster, I focus solely on evidence of extant insect-like organisms on Mars and include significant new material. Evidence to be presented supports the presence of extant insect-like ("insectoid") forms on Mars; the ability of these to walk, run, glide, and fly; the occurrence of sheltering/nesting behavior; and the presence of immature forms. Among the apparent diversity of organic forms that can be seen in the rover photos, there are two particularly common insect-like types, a relatively smaller "bee-like" (in the Earth sense) form, and a larger form. These are not necessarily insects in the Earth sense and do not necessarily represent discrete taxa, but within each group they are very similar. For convenience the Martian forms will be referred to as "bee-like insectoid" and "large insectoid". Critics of this research reject the possibility of higher life forms on Mars largely because, according to NASA, the conditions are simply too harsh to support higher life forms, and because NASA has not acknowledged their presence. Neither of these reasons should prevent an established scientist from presenting evidence to the contrary.

TYPES. During the course of this study, I have observed a number of apparently different insectoid types in the NASA/
JPL rover photos. Among these, two have stood out, a "bee-like" form (Fig. 3) and a "large" form (Fig. 4). These two
types are the focus of this poster. Individuals representing each of these types are described here. No discrete taxa are
implied, and either or both groups could include multiple types. It should also be noted that Martian insectoids are not
necessarily insects in the Earth sense, though they could be.
STRUCTURE. The following fundamental insectan structures can be identified in Martian insectoids (Figs. 3-9): (1) three
body regions — head, thorax, abdomen; (2) eyes, antennae, & mouthparts on the head; and (3) wings & legs on the
thorax. In some images, particularly those of the "large" type (Figs. 4-8), anatomical details are visible at much finer level
allowing recognition of details such as three fundamental thoracic segments, sutures, intersegmental lines, and wing
veins and cells (Figs. 6-8). Comparison of the segmentation of generalized cursorial leg of an Earth insectoid with the
hindleg of the large insectoid on Mars yields extraordinary results, that is the segmentation is essentially identical (Fig. 7).
The legs of "large" insectoids display interesting adaptations (Fig. 5-7). The forelegs are somewhat directed anteriorly
and the pretarsi look like they are composed multiple digits (Fig. 6). The midlegs appear shorter and stouter with a more-
or-less fan-shaped pretarsus. Their position and form are suggestive of a carrying function, as if they could grasp
something against their body and carry it while running/gliding or in flight. They also appear to be foldable dorsally and
placed against the pleuron when not in use (Fig. 5). The hindlegs are comparatively long, directed posteriorly, and distally
the pretarsus appears somewhat pad-like. The length and position of the hindlegs is consistent with the frequent
episodes of running displayed by these insectoids. At times, it appears as if they are essentially bipedal, using only the
hindlegs for propulsion. The comparatively large hindleg pretarsi appear to facilitate rapid running over the variable
Martian terrain.
SIZE. A fortuitous juxtaposition of elements (scale line & "large" insectoid; Fig. 8) in one of the NASA/JPL's
panoramic mosaics provides an opportunity to obtain rough estimates of several body dimensions, including wing
length & width, head width & height, and wing span. These measurements taken directly from the individual in the
photo facilitated scaling in images of other "large" insectoids in different postures, thereby allowing estimates of
structures not available for measurement in the original specimen in Fig. 8. The results of are shown in Table 1.
This poster is based on my project which involves the analysis and interpretation of
NASA/JPL Mars surface rover photographs. The focus of this project is reflected in the
title of my Facebook blog site: "Mars & Earth - Partners in Time?. The operating
hypothesis of the biological portion of this project is: "There are fossilized and extant
higher life forms on Mars, including insect/arthropod-like and reptile-like organisms."
During the 2019 ESA meeting, I presented a poster entitled: "Does Insect/Arthropod
Biodiversity Extend Beyond Earth". A copy of this poster and supplemental material can
be found on my researchgate.net page: https://www.researchgate.net/profile/

Among criteria useful in identifying and describing higher organic forms in NASA/JPL
rover photos are the following: detectable form in contrast with the surroundings, body
symmetry, segmentation of body, segmentation of appendages, and observation of
closely similar forms in proximity to one another. Particular postures, evidence of motion,
apparent interaction as suggested by relative positions are consistent with the presence
of living forms. Once a clear image of a given type is found and described, it then
facilitates recognition of other less clear, but none-the-less valid, images of same basic
form. So the actual sample sizes of types are larger than implied by the images
presented here.
A major factor in recognizing Martian insectoids is awareness that they are typically in
motion, sometimes partially hidden, and often occur in groups where the image of one
individual may interfere with the image of another. Obfuscation (circumstantial or
purposeful) and poor resolution can also be problems.
Insects typically have an overall “Gestalt” which makes them identifiable by an
experienced eye. Even in flying forms, one can often identify the order of an insect by
its overall appearance and behavior in flight. Consider a house fly, a dragonfly, and a
butterfly which most persons can readily differentiate in flight.
RUNNING & FLIGHT SIGNATURES. "Running & flight signatures” associated with
rapid movements of body parts relative to one another, or of entire bodies moving
through space include the following: (1) a blurred streak where a body part (e.g. the
head) or appendage moves, often with more than one positional view of the structure in
question; (2) a zone of blurring surrounding the body due to rapid wing movement; (3)
somewhat blurry lines that radiate out from the body during flight; (4) wing cycle (stroke,
Fig. 1) patterns revealed by pigment spots or light reflective regions on the wings distal
to the body; and (5) flight paths as indicated by multiple, sequential whole and partial
images of the same individual as it moves through space (Fig. 2).
Figure 1. Various stroke patterns displayed by insect wings. From: Lehman & Pick (2007).
Wing spots or wing surface reflections would be seen in these patterns.
Figure 2. Flight or running paths of individuals appear as if they were captured in
sequential positions by a strobe light (Fig. 1A), but in the case of Martian insectoids,
multiple images of the same individual are often captured due to both the camera
and insectoid moving. If the insectoid is flying at an angle to the plane of the
camera lens, the body size appears to go from smaller or larger, or vice versa, in
the direction of flight. This effect can be seen in Figure 1B which is a panning shot
of a skier gliding by the camera. Note that the individual images vary from nearly
complete to fragmentary. This phenomenon can be clearly seen in NASA/JPL rover
photos. (A, public domain; B, original photo)

The focus of this poster has been to present evidence of living insect-like forms or “insectoids” on
Mars. Collectively, the material included supports the hypothesis posed in the introduction, that is
"there are extant insect-like forms on Mars”.
Though aspects of any given image may be debatable, consistency of form, the numerous images of
individuals representing each of the two common types, evidence of movement, observation of
apparent immature forms, and sheltering/nesting behavior taken together is compelling.
Multiple examples of two common, but different insectoid types, "bee-like" and "large" are presented.
Since the “large” insectoids are often seen running over significant distances, I will refer to them as
“runners” henceforth. Gross insectan structural traits are clearly visible in both insectoid types. In
some images of the runners, surprising structural detail can be discerned in the thorax and legs.
This structural detail is amenable to labeling as if the insectoid was an Earth insect. Moreover, there
is clear evidence of locomotor activity and sheltering/nesting behavior.
Assuming the requirements for life on earth prevail elsewhere in the cosmos, the occurrence of
extant insect-like organisms would imply the presence of other organisms, nutrient/energy sources
and processes, food chains and webs, sufficient oxygen, and available water.
In regard to other organisms, I have observed other likely insectoid types as well as reptile-like forms
or “reptoids” (Romoser, 2019). Levin & Straat (2016) assert that evidence for microbial life on the
Martian surface was detected during the 1976 Viking lander mission. The Mars Exploration Program
Analysis Group (Rummel, Beaty, Jones et al., 2014) reviewed and updated the assessments of an
earlier group in regard to the existence on Mars of “Special Regions” (regions where terrestrial
organisms might replicate) and stated: “Significant changes in our knowledge of the capabilities of
terrestrial organisms and the existence of possibly habitable martian environments have led to a new
appreciation of where Mars Special Regions may be identified and protected.” Recently, the question
of evidence of both prokaryotic and eukaryotic life forms on Mars, including what could be viewed as
potential nutrient sources for insectoids, is addressed in a review article (Joseph, Dass, Rizzo et al.,
2019).
Water, in one form or another, has been reported a number of times (Rothschild and Mancinelli,
2001), including surface water detected by instrumentation on Viking, Pathfinder, Phoenix and
Curiosity (Levin, 2019). Subglacial water bodies have also been identified on Mars (Lauro, Pettinelli,
Caprarelli et al. 2020). During my studies I have observed instances in rover photographs
suggestive of standing water or small water courses on Mars (link).
The findings presented here are in dramatic contrast with the official position of NASA which
continues to deny even the existence of unequivocal chemical bio-signatures, that is, signs of life on
Mars. I find it extremely difficult to believe that at least a few NASA/JPL individuals or units are not
aware of the organisms I have described. Accordingly, I continue to view my project as replicative
and corroborative.
Evidence of extant life forms on Mars raises many important biological, social (Lupisella, M. 1999),
and political questions. Acceptance of the existence of life beyond Earth can be expected to impact
essentially every aspect of human life, past and present.
Evidence for living forms on Mars is salient to the discussions of the possibility of panspermia
(Crick, 1981; Kaufman, 2017).

RUNNING, GLIDING, FLYING. The bee-like forms appear to emphasize flight (Fig. 3), while the "large" insectoids
appear to emphasize what looks like bipedal running (Figs. 9 & 10), but are sometimes seen gliding and/or flying
(Figs. 10 & 11).
IMMATURE "LARGE" INSECTOID. The specimen in Fig. 12 looks like it could be an immature form since its overall
form resembles a "large" insectoid, and it appears to have developing appendages.

The detection of liquid water by the Mars Advanced Radar for Subsurface and Ionosphere Sounding (MARSIS) at the base of the south polar layered deposits in Ultimi Scopuli has reinvigorated the debate about the origin and stability of liquid water under present-day Martian conditions. To establish the extent of subglacial water in this region, we acquired new data, achieving extended radar coverage over the study area. Here, we present and discuss the results obtained by a new method of analysis of the complete MARSIS dataset, based on signal processing procedures usually applied to terrestrial polar ice sheets. Our results strengthen the claim of the detection of a liquid water body at Ultimi Scopuli and indicate the presence of other wet areas nearby. We suggest that the waters are hypersaline perchlorate brines, known to form at Martian polar regions and thought to survive for an extended period of time on a geological scale at below-eutectic temperatures.

Evidence is reviewed which supports the hypothesis that prokaryotes and eukaryotes may have colonized Mars. One source of Martian life, is Earth. A variety of species remain viable after long term exposure to the radiation intense environment of space, and may survive ejection from Earth following meteor strikes, ejection from the stratosphere and mesosphere via solar winds, and sterilization of Mars-bound spacecraft; whereas simulations studies have shown that prokaryotes, fungi and lichens survive in simulated Martian environments-findings which support the hypothesis life may have been repeatedly transferred from Earth to Mars. Four independent investigators have reported what appears to be fungi and lichens on the Martian surface, whereas a fifth investigator reported what may be cyanobacteria. In another study, a statistically significant majority of 70 experts, after examining Martian specimens photographed by NASA, identified and agreed fungi, basidiomycota ("puffballs"), and lichens may have colonized Mars. Fifteen specimens resembling and identified as "puffballs" were photographed emerging from the ground over a three day period. It is possible these latter specimens are hematite and what appears to be "growth" is due to a strong wind which uncovered these specimens-an explanation which cannot account for before and after photos of what appears to be masses of fungi growing atop and within the Mars rovers. Terrestrial hematite is in part fashioned and cemented together by prokaryotes and fungi, and thus Martian hematite may also be evidence of biology. Three independent research teams have identified sediments on Mars resembling stromatolites and outcroppings having micro meso and macro characteristics typical of terrestrial microbialites constructed by cyanobacteria. Quantitative morphological analysis determined these latter specimens are statistically and physically similar to terrestrial stromatolites. Reports of water, biological residue discovered in Martian meteor ALH84001, the seasonal waning and waxing of atmospheric and ground level Martian methane which on Earth is 90% due to biology and plant growth and decay, and results from the 1976 Mars Viking Labeled Release Experiments indicating biological activity, also support the hypothesis that Mars was, and is, a living planet. Nevertheless, much of the evidence remains circumstantial and unverified, and the possibility of life on Mars remains an open question.
Article
The 1976 Viking Labeled Release (LR) experiment was positive for extant microbial life on the surface of Mars. Experiments on both Viking landers, 4000 miles apart, yielded similar, repeatable, positive responses. While the authors eventually concluded that the experiment detected martian life, this was and remains a highly controversial conclusion. Many believe that the martian environment is inimical to life and the LR responses were nonbiological, attributed to an as-yet-unidentified oxidant (or oxidants) in the martian soil. Unfortunately, no further metabolic experiments have been conducted on Mars. Instead, follow-on missions have sought to define the martian environment, mostly searching for signs of water. These missions have collected considerable data regarding Mars as a habitat, both past and present. The purpose of this article is to consider recent findings about martian water, methane, and organics that impact the case for extant life on Mars. Further, the biological explanation of the LR and recent nonbiological hypotheses are evaluated. It is concluded that extant life is a strong possibility, that abiotic interpretations of the LR data are not conclusive, and that, even setting our conclusion aside, biology should still be considered as an explanation for the LR experiment. Because of possible contamination of Mars by terrestrial microbes after Viking, we note that the LR data are the only data we will ever have on biologically pristine martian samples.

Flying insects may enhance their flight force production by contralateral wing interaction during dorsal stroke reversal ('clap-and-fling'). In this study, we explored the forces and moments due to clap-and-fling at various wing tip trajectories, employing a dynamically scaled electromechanical flapping device. The 17 tested bio-inspired kinematic patterns were identical in stroke amplitude, stroke frequency and angle of attack with respect to the horizontal stroke plane but varied in heaving motion. Clap-and-fling induced vertical force augmentation significantly decreased with increasing vertical force production averaged over the entire stroke cycle, whereas total force augmentation was independent from changes in force produced by a single wing. Vertical force augmentation was also largely independent of forces produced due to wing rotation at the stroke reversals, the sum of rotational circulation and wake capture force. We obtained maximum (17.4%) and minimum (1.4%) vertical force augmentation in two types of figure-eight stroke kinematics whereby rate and direction of heaving motion during fling may explain 58% of the variance in vertical force augmentation. This finding suggests that vertical wing motion distinctly alters the flow regime at the beginning of the downstroke. Using an analytical model, we determined pitching moments acting on an imaginary body of the flapping device from the measured time course of forces, the changes in length of the force vector's moment arm, the position of the centre of mass and body angle. The data show that pitching moments are largely independent from mean vertical force; however, clap-and-fling reinforces mean pitching moments by approximately 21%, compared to the moments produced by a single flapping wing. Pitching moments due to clap-and-fling significantly increase with increasing vertical force augmentation and produce nose-down moments in most of the tested patterns. The analytical model, however, shows that algebraic sign and magnitude of these moments may vary distinctly depending on both body angle and the distance between the wing hinge and the animal's centre of mass. Altogether, the data suggest that the benefit of clap-and-fling wing beat for vertical force enhancement and pitch balance may change with changing heaving motion and thus wing tip trajectory during manoeuvring flight. We hypothesize that these dependencies may have shaped the evolution of wing kinematics in insects that are limited by aerodynamic lift rather than by mechanical power of their flight musculature.
