Claims based on results from Viking landers, recent claims based on evidence of methane in the martian atmosphere, and claims based on studies of martian meteorites found on Earth The Viking Experiments – study soil The third biology experiment mixed martian soil with organic nutrients Fourth experiment measured the abundance of organic molecules in the martian soil Methane gas in the martian atmosphere Methane could be coming from comet impacts, volcanic activity, or life How do we plan to search for life on Mars? Mars Reconnaissance Orbiter Mars Science Lab It’s important to make sure that our robotic mission don’t accidentally contaminate Mars with life from Earth Should we send humans to Mars? While the cost and inherent danger of sending humans to Mars would be very high, the scientific payoff could potentially be even higher Terraforming – alter martian environment in ways that would make it more hospitable to us Manufacturing chlorofluorocarbons Is there evidence of life in martian meteorites? ALH84001 is a piece of igneous rock that solidified about 4.5 billion years ago ALH84001 spent 16 million years in space, which means the impact that started its journey occurred on Mars about 16 million years ago Evidence: carbonate grains, PAHs

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
