The ESA/NASA Rosetta Mission Science: Comets and the Origin of Life on Earth

Origin of Life on Earth is an outstanding Puzzle for Humanity. One of the
many theories of the Origin of Life, is that about 4 billion years ago,
asteroids and comets bombarded Earth delivering the precursors of life and
triggered the chemical evolution of Life on Earth. These intriguing celestial
bodies are thought to be the most primitive objects in our Solar System.

Present-day comets originate from the Kuiper Belt Objects (KBOs) or Oort
Cloud, which are the left-over small bodies during the star and planet
formation process in our solar system. These small bodies are also understood
to be unfractionated careers of primordial material from interstellar space.
Comet and asteroid bombardments on Earth during the Late Heavy Bombardment
time (ca. 4 billion years ago) could have brought the material and conditions
needed to trigger life on Earth soon thereafter. ESA/NASA collaborative
ROSETTA mission to comet 67P/Churyumov–Gerasimenko provided outstanding data
about a short-period Jupiter-family comet. Many complex organic molecules
that are important for life, including an amino acid Glycine, have been
detected outgassing from this comet that are also reproduced from laboratory
measurements. This presentation will discuss some of the exciting scientific
discoveries on comets, and how laboratory investigations and space missions
help us to address the puzzle of the “Origin of Life on Earth”.
