A man/system simulation test program is being conducted at NASA's Marshall Space Flight Center (MSFC) to support design and evaluation of crew interface hardware used in the Space Telescope (ST) on-orbit servicing tasks. A neutral buoyancy (NB) mockup of the telescope developed for MSFC was used as a test bed for evaluating many proposed crew interfaces associated with changeout of the scientific instruments and support systems. Tests were conducted in MSFC's NB simulator under simulated weightless conditions using pressure-suited crew members as test subjects. Test results are presented, including suggestions and recommendations for the design of tools, crew restraints, instrument stowage and transfer devices, and insertion guiderails. A final discussion applies the lessons learned from Space Telescope to the design of other serviceable spacecraft.

Standardless Analysis

Committee E-04 on Metallography of the American Society for Testing and Materials (ASTM) conducted an interlaboratory round robin test program on quantitative energy dispersive spectroscopy (EDS). The test program was designed to produce data on which to base a precision and bias statement for quantitative analysis by EDS. Nine laboratories were sent specimens of two well characterized materials, a type 308 stainless steel, and a complex mechanical alloy from Inco Alloys International, Inconel® MA 6000. The stainless steel was chosen as an example of a straightforward analysis with no special problems. The mechanical alloy was selected because elements were present in a wide range of concentrations; K, L, and M lines were involved; and Ta was severely overlapped with W. The test aimed to establish limits of precision that could be routinely achieved by capable laboratories operating under real world conditions. The participants were first allowed to use their own best procedures, but later were instructed to repeat the analysis using specified conditions: 20 kV accelerating voltage, 200s live time, ∼25% dead time and ∼40° takeoff angle. They were also asked to run a standardless analysis.
