Mars did indeed lose much of its original atmosphere long ago when huge amounts of gas escaped into space, new analyses from NASA's Curiosity rover suggest. Stephen F. Knott has written: 'A study of helium and argon isotopes in extraterrestrial dust and a meteorite from Mars' 'Alexander Hamilton And the Persistence of.

The meteorite is mostly composed of volcanic rocks like basalt – evidence of Mars’ volcanic past. The study’s authors found the Martian zircons ranged in. For instance, stable-isotope values (δ 13 C, δ 15 N, δD) of organic extracts of the Murchison meteorite are moderately-to-highly enriched in the heavy stable isotopes (13 C.

A study of the famed rock published in todays issue of Science examines whether life--if it existed--could have traveled from Mars to Earth. Thus, from a single, small meteorite, a rather epic narrative suggests itself: Before four billion years ago Mars was already dying, rapidly losing its interior heat to .
