Three documents discuss the Sustainable Objective Valuation and Attainability (SOVA) algorithm and software as used to plan tasks (principally, scientific observations and associated maneuvers) for the Far Ultraviolet Spectroscopic Explorer (FUSE) satellite. SOVA is a means of managing risk in a...

A patent disclosure document discusses a photonic method for connecting a spacecraft with a launch vehicle upper-stage telemetry system as a means for monitoring a spacecraft’s health and status during and right after separation and deployment. This method also provides an efficient...

A document discusses an approach to insulating propulsion lines for spacecraft. In spacecraft that have propulsion lines that are located externally with open bus architecture, the lines are typically insulated by Multi Layer Insulation (MLI) blankets. MLI on propulsion lines tends to...

Test and evaluation relies on computer collection and manipulation of data from a myriad of sensors and sources. More computing power allows for increases in the breadth and depth of the information collected. The same computing power must assist in identifying, ordering,...

T est and evaluation of current systems is a time-consuming process that reflects both the intricacies of the object of the test and the range of equipment, personnel, and environments required. Many argue that this process consumes far too much of the time that it takes to put new systems into...

A ircraft and rotorcraft structures are being redesigned with new lower weight materials; however, older metallic structures continue to be used. These older structures need monitoring and characterization of damage for con- tinued operation. The use of...
