iss056e037491 (June 26, 2018) --- Astronaut Serena Auñón-Chancellor from NASA works on the Microgravity Investigation of Cement Solidification (MICS) 2 experiment aboard the International Space Station. MICS 2 is researching how cement reacts in space during the hardening process and may help engineers better understand its microstructure and material properties. Observations could improve cement processing techniques on Earth and lead to the design of safer, lightweight space habitats.
