At the Mid Deck Glove Box (MGBX), astronaut Donald A. Thomas, mission specialist, prepares to conduct the Internal Flows in Free Drops (IFFD) experiment. The IFFD is meant to study drops of several liquids, including water, water/glycerin and silicon oil. Flows within the drops and shape and stability are studied under varying acoustic pressure. The MGBX is the overall facility that holds experiments on materials that are not approved for study in the open Spacelab environment.
