Chassigny Meteorite fell in
1815 contains different gases than the current Martian atmosphere indicating it's from Red Planet.
Meteorite New study
upsets theories on the formation of rocky planets(Venus, Earth, and Mars)
Volatile elements like
hydrogen, carbon, oxygen, nitrogen, & noble gases are acquired from the nebula around a young star.
Chondritic meteors impacting
the young planet then deliver more volatile materials.
Scientists expected that the
volatile elements should reflect the composition of the solar nebula or a mixture of solar and meteorite origins.
The volatiles in
the atmosphere, would primarily come from meteorites.
Noble gases sample ratio
can differentiate between the Solar Nebula and Meteorites
