By Nicole WillettRed Planet Pen (Issue #10 - Updated)10.27.13NASA has released information pertaining to the origin of Martian meteorites. The Curiosity Rover has used its Sample Analysis at Mars instrument to analyze the composition of the atmosphere of the Red Planet. The scientists paid close attention to two isotopes of Argon that are present in the atmosphere of Mars. The forms of interest were Argon-36 and Argon-38. There are specific ratios of Argon throughout the solar system. The gaseous ratio on Mars is of particular interest in order to compare the gases trapped inside the meteorites that have landed on Earth and have long been suspected to have originated on the Red Planet. Mars has lost a significant amount of its atmosphere over the history of the solar system. The lighter form of Argon has been lost to space and the heavier form has remained more intact in what is left of the atmosphere. The inert nature of Argon, which is a noble gas, makes it especially relevant to the research of the origin of meteorites from Mars. Being inert means it does not react readily with other gases, so it is stable for a significant amount of time. When ...
