NASA Photo ID: STS004-28-330 File Name: 10060806.jpg Film Type: 35mm CN Date Taken: 07/04/82 Title: Columbia, OV-102, forward middeck locker experiments and meal tray assemblies Description: Overall view of forward middeck locker shows Continuous Flow Electrophoresis System (CFES) experiment control and monitoring module and sample storage module (on port side) and Monodisperse Latex Reactor (MLR) (on starboard side). Water Dispenser Kit water gun (above CFES module) and meal tray assemblies covered with snack food packages and beverage containers appear around the two experiments. Thanks to a variety of juices and other food items, this array in the middeck probably represents the most colorful area onboard the Earth-orbiting Columbia, Orbiter Vehicle (OV) 102. Most of the meal items have been carefully fastened to meal tray assemblies (foodtrays) and locker doors (or both). What has not been attached by conventional methods has been safely "tucked" under something heavy (note jacket shoved into space occupied MLR). MLR is making its second flight and is designed to test the flexibility of making large-size, monodisperse (same size), polystyrene latex micro-spheres using the products of STS-3 mission as seed particles. The latex spheres are used in calibration of scientific and industrial equipment and have potential for medical and research applications.
