TeikyoSat 3 (Microbial Observation Satellite) is a small life science satellite built by Teikyo University.

TeikyoSat 3 is designed to study the impact of space radiation and the microgravity environment on a mold called Dictyostelium discoideum. This species of soil-living amoeba belongs to the phylum Mycetozoa and is often given the less than high-brow biological label of "slime mold." The life cycle of D. discoideum is relatively short, which allows for timely viewing of all the stages of its life.

TeikyoSat 3 was launched on Japan's H-2A-202 booster in 2014, and rode along with the Global Precipitation Measurement (GPM) main satellite. The satellite suffered from communication system issues.
