A system that estimates the global radius of curvature (GRoC) of a segmented telescope mirror has been developed by the Marshall Space Flight Center for use in a larger system that exerts precise control over the displacements of the mirror segments. This system makes it possible to control the GRoC of the mirror with sufficient precision to obtain the best possible image quality, and to impose a required wavefront correction on incoming or outgoing light.

The Johnson Space Center offers a Mathcad computer program that largely automates the design and analysis of the restraint layer of an inflatable vessel. Prior to the development of this program, the design task was performed by use of a difficult-to-use spreadsheet program that required manual addition of rows and columns, depending on the numbers of strap rows and columns of a given design.

Measuring Positions of Objects Using Two or More Cameras

This method could determine the causes of accidents. An improved method of computing positions of objects from digitized images acquired by two or more cameras (see figure) has been developed for use in tracking debris shed by a spacecraft during and shortly after launch. The method is also readily adaptable to such applications as (1) tracking moving and possibly interacting objects in other settings in order to determine causes of accidents and (2) measuring positions of stationary objects, as in surveying. Images acquired by cameras fixed to the ground and/or cameras mounted on tracking telescopes can be used in this method.

Charge-Control Unit for Testing Lithium-Ion Cells

This unit is useful for testing any non-aerospace battery cells. A charge-control unit was developed as part of a program to validate Li-ion cells packaged together in batteries for aerospace use. The lithium-ion cell charge- control unit will be useful to anyone who performs testing of battery cells for aerospace and non- aerospace uses and to anyone who manufacturers battery test equipment. This technology reduces the quantity of costly power supplies and independent channels that are needed for test programs in which multiple cells are tested. The cost savings that were achieved in a test program are shown in Figure 1. Battery test equipment manufacturers can integrate the technology into their battery test equipment as a method to manage charging of multiple cells in series.
