Document Summary

In 1997 president clinton creates an origins initiative as a mission for nasa to try and organize missions to mars and europa to try and discover extra terrestrial life: types of forces, gravity, electromagnetivity, strong nuclear force. The force that holds the atom together: weak nuclear force. Solid metal (hot: two hypothesis for the differentiation of the early earth, homogenous accretion theory, inhomogeneous accretion theory, the main types of rock, sedimentary rock, igneous rock. As one goes away from the sun the water made up deuterium increases: oceans form in 3 steps. Comets bring in the water but cannot stay in liquid but form a thick atmosphere while the earth is hot. Lastly the oceans condensate from the precipitation: possible origins of water expansion) The most interest to the astrobiology community. Among this category is a martian meteorite that is the oldest piece of rock we have found so far in the solar system.
