(04/04/1997) --- STS-83 Payload Specialist Roger K. Crouch is assisted into his launch/entry suit in the Operations and Checkout (O&C) Building. He is the Chief Scientist of the NASA Microgravity Space and Applications Division. He also has served as a Program Scientist for previous Spacelab microgravity missions and is an expert in semiconductor crystal growth. Since Crouch has more than 25 years of experience as a materials scientist, he will be concentrating on the five physics of materials processing experiments in the Middeck Glovebox Facility on the Blue shift. He will also share the workload with Thomas by monitoring the materials furnace experiments during this time. Crouch and six fellow crew members will shortly depart the O&C and head for Launch Pad 39A, where the Space Shuttle Columbia will lift off during a launch window that opens at 2:00 p.m. EST, April 4
