Document Summary
Orbit & rotation: similar to earth in days, has seasons due to axis. Spring in south: white polar caps shrinks and grey surface markings. Spirit: currently stuck in sand, there has been no communication due to low power. Opportunity: looked for evidence of clay which associated with wet environments. Mars curiosity: designed to be best, travel over terrains, dig deeper and further/faster, measured composition of atmos, analysis of igneous rocks and soil that show large concentration of water. Objectives: if mars held microbial life: explore presence of water, climate, geology. Co2 (96%), n (2%), ag (2%: contains traces of water vapour/o2, doesn"t provide enough pressure into prevent liquid water from boiling into vapour, originally would have primitative atmosphere of h, he but later replaced by. Clouds & winds red soil caused by iron oxides (rust: polar caps are frozen water and co2.
