Priority:1
Status: In-progress

Research on Cosmic Matter on the Earth and in Nearby Space;
Research on the Biological and Geochemical Specifics
of the Early Earth


Leaders:     E.A. Krasavin
A.Yu. Rozanov
V.N. Shvetsov

Participating Countries and International Organizations:
Italy, Norway, Poland, Romania, Russia, United Kingdom, USA.

Scientific Programme:
Research and development will include:
  • Biogeochemical studies of cosmic dust

  • Studies of biofossils and organic compounds in meteorites and ancient terrestrial rocks

  • Studies of cosmic matter with nuclear physics methods

  • As a result of studying and generalizing the research materials on modern and fossil cosmic dust as well as ancient terrestrial objects and modern organisms of the extreme ecosystems, data will be obtained on the forms of ancient terrestrial and extraterrestrial life.
As the results:
  • Obtaining new data on the amount of cosmic matter falling on the whole Earth's surface. Obtaining data on the dynamics of cosmic dust fallout on large territories.

  • Evaluation of the following parameters of particles of extraterrestrial origin: morphology, structure, size distribution, and elemental, isotopic, and mineralogical composition. Assessment of changes in these characteristics in different plates in different time intervals.

  • Creation of a cosmic dust collection, where dust microparticles will be characterized by quantity (concentration) and the size distribution.

  • Obtaining new information on the role of microorganisms in the formation and evolution of life on the Earth and processes of weathering, precipitation growth, etc.

  • Research on the synthesis of complex prebiotic compounds from formamide under exposure to ionizing radiations of different qualities with meteorite samples as catalysts.

  • Generalization of the obtained data on the forms of ancient terrestrial and, possibly, extraterrestrial life.
Expected main results in 2018:
  • To continue the electron microscopy-based detection and study of biofossils and organic matter in meteorites and the most ancient terrestrial rocks.

  • To continue the diagnostics of microorganism remnants in Archaean and Proterozoic rocks and evaluation of their organization level with nuclear physics methods.

  • To continue research on the synthesis of complex prebiotic compounds from formamide under exposure to accelerated ions with different linear energy transfer.

  • To study the nature of the catalysts participating in the synthesis of complex prebiotic compounds from formamide.
