Observational tests for grain chemistry: posterior isotopic labelling
Steven B. Charnley,Pascale Ehrenfreund,Tom J. Millar,Adwin Boogert,A. J. Markwick,Harold M. Butner,R. Ruiterkamp,S. D. Rodgers +7 more
TL;DR: In this paper, a series of detailed observations that should allow current ideas concerning the important catalytic pathways to interstellar molecules on interstellar dust grains to be tested was proposed. But the results were limited to the case where the atoms and molecules that accrete on cold grains and take part in surface reactions were selectively fractionated in 13C.

TL;DR: The Biology and Mars Experiment (BIOMEX) as mentioned in this paper is an interdisciplinary and international space research project selected by ESA to measure to what extent biomolecules, such as pigments and cellular components, are resistant to and able to maintain their stability under space and Mars-like conditions.

TL;DR: The MarcoPolo-R mission as discussed by the authors is a sample return mission to a primitive Near-Earth Asteroid (NEA) selected in February 2011 for the Assessment Study Phase at ESA in the framework of ESAfs Cosmic Vision 2 program.
Experimentally Tracing the Key Steps in the Origin of Life: The Aromatic World
Pascale Ehrenfreund,Steen Rasmussen,Steen Rasmussen,Steen Rasmussen,James Cleaves,Liaohai Chen +5 more
TL;DR: Current knowledge of the composition of prebiotic organic material of extraterrestrial and terrestrial origin is put in the context of possible prebiotics scenarios and laboratory experiments are described that might help clarify the transition from nonliving to living matter using aromatic material.
