Is There Life On Mars?<\/p>\n
Becker, R. “Is there Life on Mars? Where is the Proof.”\u00a0Journal of Astrobiology\u00a0vol. 7 no.1 (August. 2021): 38-75. http:\/\/journalofastrobiology.com\/IsThereLifeOnMarsBecker.pdf <\/p>\n
Many scientists have many questions about Mars being wet and habitable in the past and whether the red planet can still support life. The article studies the publication “Fungi on Mars?” which shows evidence through 50 photos of samplings that look like lichens, earthly fungi, and sphere-shaped fungi growing on Mars. The same team published evidence on tubeworm’s thermal vents evident in the endurance crater. Other evidence presented involves fossils, living algae, lichens, and stromatolites growing on Mars. The article reviews these findings while offering alternative explanations, although there is no actual evidence on specimens being alive in mars. The paper focuses on biogeochemical phases, distinctive methane, and current variances that liquefy ice-covered water deposits. The findings show inconclusive proof of present life on Mars. <\/p>\n

The article explores the indigenous Martian life. The issue of lifecycle on Mars has been a long-lasting issue of speculation where the past, present, and future queries are getting to a fresh epoch of in situ samplings and exploration. The article builds its research based on revolutionary studies done thru the Viking tasks in the mid-1970s, which offers substantial evidence that microbial existence has occurred and may still happen with Martian regolith. The article findings provide insights on past evidence touching surface fossils, biodeposition characteristics, and bioerosion. Present-day evidence involves geological structures, e.g., lava tubes found on the deep surface of the planet. The article reviews analogy sites on earth, comparing the geological and microclimate conditions to Mars. <\/p>\n

The article studies the mushroom lichen-like formations photographed at Eagle Crater, clustered in colonies, and jutted outwards on top and side of rocks. The article reviews the reports showing that eagle crater spheres have hematite and find that the study is based on extrapolation as the implements used are not detailed hematite. The article targets oblongs rocks with spherical features and uses a selective method to eliminate spectra from panoramic images. The evidence reviewed resembled spectral signatures of terrestrial hematite, which was a “poor fit.” The article findings show that Eagle Crater’s conditions are not favorable to producing hematite, and the sphere-shaped hematite assumption is rebutted. However, lichens and fungi endure in Mars-like correspondent settings; although no process can enlighten the mushroom morphology, dimension, color, etc., it shows that mushrooms, algae, etc., are in the Red Planet and help in photosynthesis and oxygen production in Mars.<\/p>\n

The article tries to understand the possibility of life on Mars. The research is based on the arguments of overpopulation on earth, decreased global resources, and the needs of a great population. The article argues that there is no evidence to show that Mars can support life. Still, there is evidence that Mars’s surface setting contained liquid water during the Noachian Ancient Period, which is helpful for microorganisms. The piece uses the 2016 development that investigated and positioned a communication outpost on Marte’s trajectory and the 2020 venture of a rambler alighting on Mars. Research about life on Mars necessitates looking at Martian liquids and geochemical settings, distinctive gas, and other foundations. However, there is still no evidence of life’s existence on Mars. <\/p>\n

The article discusses life on Mars billions of years ago when the sun was cooler and less luminous. The article argues that there existed primitive life forms in the younger oceans found on Mars and Earth, representing an optimistic and biology-approachable prospect. Over the ages, the planet has experienced various transformations, which led to the death of Mars while Earth remained oxygen-rich, temperate hence continued life support. Some indicators of early life on mars touch on fossil records which have in over 100 million years have been left on land-living and masses and various left-behind imprints of telltale imprints by various organisms. Today, Mars has non-life supporting conditions, e.g., the little pure atmosphere on Mars, vast contaminated water, and inadequate pressure for liquid water to exist. The article shows evidence of life on Mars billion years ago, but currently, Mars does not support life due to changes in atmospheric conditions. <\/p>\n
