Mars Geology

Good Essays
A recent study on Mars’s geology causes a paradigm shift to researchers’ perspective of the red planet. Felsic rocks that thought to not exist on Mars are now identified. Overall, these findings alter the understanding of the geologic complexity and magmatic activity of Mars.

Prior knowledge of Mars’s geology was rather simple; consisting of one type of rock formation in contrast to Earth’s diverse and complex geology. Felsic rocks such as granite, are common in subduction zones on Earth (Wray et al., 2013, 1013). However, in Mars, felsic rocks are nonexistent and only contain mafic rocks. Researcher James Wray et al., (2013) argued that due to the lack evidence of plate tectonics and early forms of magma have been altered by natural causes or buried subsequently, felsic rocks were never present on Mars.

Since Mars is much distant from Earth, observations are done through the use of thermal infrared spectroscopy of THEMIS and Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) which aboard the Mars Reconnaissance Orbiter (Wray et al., 2013, 1013). CRISM absorbs infrared wavelengths that reflect on the planet’s surface detecting rock compositions. Although Mars was said to have no felsic rock formation, CRISM detected areas where felsic rocks are present, despite the difficulty to identify legitimate materials that can be considered as

    The Mars Exploration Rover (MER) Mission is a mission started by NASA. This ongoing robotic space mission involves two rovers, Opportunity (MER-B) and Spirit (MER-A), to explore planet Mars’ surface and geology. The scientific objective of this mission is to search for a wide range of rocks and soils that may be a clue to Mars’ past water activity. The mission’s objective is also to determine what the minerals, rocks, and soils on Mars are composed of. Over the next few decades, NASA will conduct…

In just sixty-six years, society went from the first powered flight, by the Wright brothers in 1903, to the Apollo 11 moon landing in 1969. Now our attention has been focused on Mars and whether or not life can, or ever has, existed on the Red Planet. Jim Bell, a professor that specializes in the study…
