Second space exposure experiment “TANPOPO 2” on the International Space Station was planned for study of origin of life. Authors were tried to synthesis peptides those are condensation products of amino acids, because peptides syntheses are the most important step for the producing proteins on the primitive Earth before the first life aperance. Although, in our preliminary experiments in the first space exposure experiment “TANPOPO”, authors found dialanine that is a dipeptide from amino acid, alanine, the experimental result was not enough to conclude peptide formed in the space. Therefore, precise experiments were planned in the “TANPOPO2”. Stable isotope labeled alanine was used for preventing the biological contamination, three different patterns of amino acids were chosen to conclude wide variety peptides formation. In this experiment, thin film formation apparatus using vaporization of amino acids, spectrometry of vacuum ultraviolet adsorption were prepared for the space experiment. And the space exposure experiment was started from August, 2019.
