Introduction Conclusions References Tables Figures Back Close Abstract Introduction Conclusions References Tables Figures Back Close Abstract The Biosphere is considered to represent the Earth's crust, atmosphere, oceans, and ice caps and the living organisms that survive within this habitat. This paper considers the significance of comets and carbonaceous meteorites to the origin and evolution...

The Relative Abundance of Recently-launched Meteorites from the Moon

Introduction: It has been known for over 20 years that certain meteorites originated on the moon and Mars. The launch and delivery of these stones is understood qualitatively as a consequence of impact events on those bodies. One of the puzzling features of the sample population is the relative abundance of lunar vs. Martian meteorites. One would think that lunar meteorites should be much more ...

Pg. S3, Paragraphs 1-4. I fully agree with the reviewer that the Whipple “dirty snowball” was hit hard by the results from the probes to comet Halley. However, the “dirty snowball” model has continued to persist, despite all data to the contrary and it is for that reason that I chose the word “paradigm.” That seems to be the nature of paradigms; they are so deeply entrenched into the consensus ...

Deuterium Fractionation: the Ariadne’s Thread from the Pre-collapse Phase to Meteorites and Comets today

The Solar System formed about 4.6 billion years ago from a condensation of matter inside a molecular cloud. Trying to reconstruct what happened is the goal of this chapter. For that, we put together our understanding of Galactic objects that will eventually form new suns and planetary systems, with our knowledge on comets, meteorites and small bodies of the Solar System today. Our specific tool...
