Unformatted text preview: R ecent Ma rs –Seth Klebe Physical: • Mars has about ½ the radius of Earth. • There are 2 polar ice caps that if melted, could drown the planet i n 11 meters of water. • The soil is fairly alkaline with a Ph of 8.3 and could support life i f i t was on Earth. • Temperatures run from -125 to 23 Degrees Farenheit. • Landforms include valleys, aquifers, t roughs, potential caves, and volcanoes. M issions: • Dozens of orbiters, landers, and rovers have been assigned to M ars from all around the world since the technology has been developed. • The NASA Mariner 4 was the first successful mars orbit, and the Soviet Mars 2 was the first to land. • Currently orbiting mars is the Mars Recon Orbiter, Mars E xpress, and 2001 Mars Odyssey. • The Opportuni ty Rover is functioning on Mars and performs geological analysis. • About 2/3 of spacecraft designated for Mars has failed due to t echnical issues. Current evidence & Meteori tes: • Aquifer landforms suggest f lowing water at one point in time on mars. • Soils suggest that life could grow on Mars. • Meteori te ALH84001 is an igneous rock that has bored holes t hat could be from ancient microbes. -H igh-resolution microscope photos also reveal potential microfossils. • Of the 12 Martian meteori tes found, some contain highmolecular weight organic matter.
