Alexander Gerst with the MICS Experiment

Caption

European Space Agency astronaut Alexander Gerst works on the MICS experiment aboard the International Space Station. Observations of how cement reacts in space during the hardening process may help engineers better understand its microstructure and material properties, which could improve cement processing techniques on Earth and lead to the design of safe, lightweight space habitats.
