Hans F. Wuenscher, assistant director for Advanced Space Projects Engineering Laboratory at Marshall Space Flight Center (MSFC), examined the facility to be used by Skylab astronauts in performing a number of experiments in material science and manufacturing in space. The equipment shown here is a duplicate of the M512 Experiment hardware flown in the Multiple Docking Adapter section of the Sky lab. This equipment, itself an experiment, was be used for conducting 5 other experiments in the round vacuum chamber. Inside was a cavity which held the M518 Multipurpose Electric Furnace, a facility which was used for conducting other experiments. In all, a total of 17 experiments were conducted using this facility and furnace.
