New Research Places Mars Bulk Composition In Question
Rethinking The C1 Carbonaceous Chondrite Standard
which describes how scientists have determined the density of Mars
from Pathfinder data, and how it is changing the assumptions of
planetary formation.
Prior to this publication, scientists assumed that C1 carbonaceous
chondrite elemental abundances were typical of the material that
accreted to form the inner planets, except for Mercury.
This model is now questioned.
Evidence points to the idea that the pre-solar nebula
was not as homogenous as believed.
