Bioorganic molecules, such as amino acids, nucleobases, and sugars, are widely distributed in space. Here, the authors investigated solid-state condensation reactions of these prebiotic organic molecules under the combined effects of ionizing radiation and forsterite on the Chinese Space Station, and showed that cumulative low-dose ionizing radiation can trigger dipeptide formations and phosphorylation of ribose.
