iss057e106264 (Nov. 27, 2018) --- Flight Engineer Serena Auñón-Chancellor mixes samples for the Microgravity Investigation of Cement Solidification (MICS) experiment and installs them into the Multi-use Variable-g Platform. The research utilizes the microgravity environment aboard the International Space Station to investigate the complex process of cement solidification. Results may impact possible construction processes and designs for space habitats on the surface of the Moon and Mars.

KENNEDY SPACE CENTER, FLA. - The STS-120 crew is at Kennedy for a crew equipment interface test, or CEIT. Receiving a briefing on the thermal protection system, or TPS, tiles on space shuttle Discovery in Orbiter Processing Facility bay 3 are Commander Pamela A. Melroy and Mission Specialist Paolo A. Nespoli, a European Space Agency astronaut from Italy. Among the activities standard to a CEIT are harness training, inspection of the thermal protection system and camera operation for planned extravehicular activities, or EVAs. The STS-120 mission will deliver the Harmony module, christened after a school contest, which will provide attachment points for European and Japanese laboratory modules on the International Space Station. Known in technical circles as Node 2, it is similar to the six-sided Unity module that links the U.S. and Russian sections of the station. Built in Italy for the United States, Harmony will be the first new U.S. pressurized component to be added. The STS-120
