Mars: new insights and unresolved questions
Mars exploration motivates the search for extraterrestrial life, the development of space technologies, and the design of human missions and habitations. Here, we seek new insights and pose unresolved questions relating to the natural history of Mars, habitability, robotic and human exploration, planetary protection, and the impacts on human society. Key observations
and findings include:
– high escape rates of early Mars’ atmosphere, including loss of water, impact present-day habitability;
– putative fossils on Mars will likely be ambiguous biomarkers for life;
– microbial contamination resulting from human habitation is unavoidable; and
– based on Mars’ current planetary protection category, robotic payload(s) should characterize the local martian environment for any life-forms prior to human habitation.Some of the outstanding questions are:– which interpretation of the hemispheric dichotomy of the planet is correct;
– to what degree did deep-penetrating faults transport subsurface liquids to Mars’ surface;
– in what abundance are carbonates formed by atmospheric processes;
– what properties of martian meteorites could be used to constrain their source locations;
– the origin(s) of organic macromolecules;
– was/is Mars inhabited;
– how can missions designed to uncover microbial activity in the subsurface eliminate potential false positives caused by microbial contaminants from Earth;
– how can we ensure that humans and microbes form a stable and benign biosphere; and
– should humans relate to putative extraterrestrial life from a biocentric viewpoint (preservation of all biology), or anthropocentric viewpoint of expanding habitation of space?Studies of Mars’ evolution can shed light on the habitability of extrasolar planets. In addition,
Mars exploration can drive future policy developments and confirm (or put into question) the
feasibility and/or extent of human habitability of space

Astrobiology in Teacher Training. Addressing research methodology and epistemology in Humanities and social-science classes
In a preliminary empirical study of social-science and humanities students enrolled in teacher-training programs at two German universities, the authors have found a disparaging view of technology and science among said students. Their material knowledge of technology and science is the result of content they learned in high-school themselves. After having graduated, they chose social-sciences or humanities as their subjects. There is little or no overlap between science and engineering subjects and social-science and humanities subjects in teacher training programs. Apart from the students choices, this is also the consequence of an institutionally established and strict segregation of the academic fields that does not, unlike in other university systems, require the students to enroll in at least basic interdisciplinary courses. The result for science and technology awareness among the students is problematic, to say the least. While their knowledge of science and technology -being the product of high-school education - is often not up to date and also lacking in current developments, their moral and ethical judgement about the implications of scientific research and use of technology is strong. The preliminary study also showed that the students are interested in new technological and scientific developments, they just lack the ability to include this into their worldview, which is very strongly influenced by their choice of subjects in the humanities and social-sciences. Teaching these students has convinced the authors that their lack of technology and science knowledge combined with their inherent tendency to judge science and technology from the point of view of their respective field, impairs their ability to take an adequate part in science and technology discourse. Their awareness, and thus, their competence to rationally engage with science and technology is lacking. That is in part due to the depiction of science and technology in humanities and social-science courses, and on the other hand due to a lack of current science and technology education as part of a humanities and social-sciences program. The result becomes even more alarming if we assume that the future teachers will continue to relay their heavily biased opinions on science and technology in general, as well as their deficient knowledge of specific technologies to their future students, thus generating a vicious cycle of inadequate technology and science awareness. As the authors’ study has shown, these students are really interested in science and technology, they just lack key competencies to make an analytical connection between their field of choice (humanities and social sciences) and technology and science, without resorting to moral and ethical judgement
