Outline of Research at the Start	Life on Earth contains L-amino acids. These can be found in meteorites, which may thus represent the source of L-amino acids at the origin of life on Earth. Meteorites may contain Earth biological contamination. Here it will be determined if L-amino acid excesses are present in non-Earth samples.
