    • 2. What is Astrobiology? What is Astrobiology? Astrobiology is an interdisciplinary science based on astrophysics and biology that examines the foundations of life in a number of ways.
    • 3. Astrobiology Astrobiology This scientific interdisciplinary field includes the research of habitable environments within and outside our Solar System, the investigation of abiogenesis (prebiotic chemistry) evidence, the life on Mars and our Solar System, Laboratory studies on the origins and early stages of the evolution of life on Earth, and the adaptation of the life potential to the challenges of the Earth and space.
    • 4. Definition of Astrobiology Definition of Astrobiology This definition of Astrobiology includes the assumption that life may have emerged on earth as well as elsewhere in or out of our solar system, as well as on other planets. Since life traces may be present on other cosmic bodies containing "fundamentally different environments" than ours, it is possible to investigate possible processes that govern evolution from "simple organic matter"(biomolecules, peptides, nucleic acids, or lipid chains) to more complex structures (first cells, first genetic systems) in astrobiology.
    • 5. Astrobiology Astrobiology Therefore, in the research of these processes, it becomes inevitable that they will have a deep interaction with a variety of scientific fields, such as organic chemistry, biochemistry, cell biology, climatology, geochemistry, Planetary Science and informatics modeling, to complement a whole of them.
    • 6. Astrobiology Astrobiology For example, astrobiologists work in collaboration with astronomers. Chemists to explore new planets and determine their livability, to study the transition from molecular interactions to life, to geology to explore key minerals and water evidence on other planets, to explore and understand the earliest life forms, as well as paleontologists and molecular biologists, as well as climatologists, planetary scientists, and scientists in various.
    • 7. Astrobiology Astrobiology Today, the growing astrobiology is also interested in the research of extraterrestrial life, regardless of species, and the research of intelligent life, if any, outside the world (extraterrestrial intelligent life research). However, this recent research area (extraterrestrial intelligent life research), which is waiting for possible developments, is very marginal for now.
    • 8. Astrobiology Astrobiology Astrobiology uses physics, chemistry, astronomy, molecular biology, ecology, and geology in order to make theoretical predictions about the nature of life in other worlds and to identify and distinguish biospheres that may differ from that of Earth. astrobiology focuses primarily on the interpretation of more scientific data, i.e. the interpretation of detailed and reliable data about other environments of the universe,
    • 9. Overview Overview The term astrobiology is a combination of the words Astron (star, constellation) in ancient Greek, BIOS (βίος) meaning “life”, and logia (- λογία ) meaning “study, review”. Astrobiology is an area that has emerged relatively recently and is still developing. The question of whether there is life in other parts of the universe is an issue where scientific inquiry is valid, since it contains a verifiable assumption.
    • 10. Overview Overview David Grinspoon, a planetary scientist, looks at astrobiology as a kind of natural philosophy that speculates about “unknown” within known scientific theories. Astrobiology, however, is a methodical field of study in the event that scientific inquiry is excluded from the mainstream. NASA prepared its first astrobiological project in 1959 and determined its astrobiological program in 1960.
    • 11. Overview Overview The Viking missions project, which NASA launched in 1976, included three experiments in biology to investigate possible signs of life. In 1971, NASA launched an extra-Terrestrial intelligence project, the short-name set. The aim of the project was to determine the presence of messages coming from an extraterrestrial civilization or distant planet and to examine them if they were to be discovered. The project focused on research on possible extraterrestrial intelligent life, especially by listening to radio signals.
    • 12. Overview Overview Astrobiology 21.century.the solar system of NASA and the ESA (European Space Agency) has become a focus of increasing importance in reconnaissance projects. In this area, the first application of Europeans on astrobiology took place in May 2001 in Italy, followed by the Aurora program Currently, NASA's Astrobiology Institute continues to work in this field and astrobiology, both taught in universities in the U.S. (University of Arizona, Penn State University) and British (University of Glamorgan) universities in other countries such as Canada, Ireland, is becoming increasingly widespread in universities.
    • 13. Overview Overview Today, a special research area of astrobiology is the study of life on Mars due to its proximity to earth and its geological history. There is sufficient evidence today that there is abundant liquid water on the surface of Mars in the past. As is known, water is considered a pre-symptom of the formation of carbon-based life. Both of the Beagle-2 probe tools with the Viking program were commissioned specifically to study life on Mars. In this regard, the results of the Viking program are considered inadequate. the Beagle-2 was broken down.
    • 14. Overview Overview Another project in which Astrobiology would be the leading role was the Jupiter Icy Moons Orbiter Project. But the change in NASA's preferences and the cut-off of funding in 2005 brought about the cancellation of the project. At present, Phoenix is researching the environment and the history of the water on the trip to explain the current situation of microbial life on Mars. NASA plans to launch the Mars Science Laboratory's space exploration tool in 2009 for a version of this research with different science tools.
