A signaling-and-detection scheme has been proposed for use in conjunction with the remote-monitoring concept described in "Beacon Monitoring Would Reduce Interactions With Remote Systems" (NPO-19706), NASA Tech Briefs, Vol. 21, No. 5 (May 1997), page 54. To recapitulate: A remote system (a...

Two reports describe early phases of continuing studies directed toward the selection and adaptation of industrial work-measurement and methods-analysis procedures for application to the Orbiter Processing Facility (OPF) at Kennedy Space Center. These studies were prompted by a need to...

DARTS Shell (Dshell) is a multimission spacecraft simulator for the development, integration, and test of flight software and hardware. Dshell reduces the time and cost of developing simulation programs by enabling the development of the software in modular, reusable form and by...

The Flight Software Memory Tracker (FMT) computer program is a collection of utility subprograms developed for use on the ground to track images of the flight software (FSW) in the computers aboard the Cassini spacecraft. [As used here, "images" signifies both (1) the memory load and...

The paper entitled "Potential Commercial Applications From Combustion and Fire Research in Space" reviews the status of potential commercial applications derived from research on combustion in microgravity environments encountered in orbiting spacecraft. Such research...

The Virtual Reality Mars Atlas User Interface (VR-MAUI) provides an atlaslike interface for access to Mars data. This access is provided via the World Wide Web, using JAVA. Within VR-MAUI, images are organized as maps. These maps provide a natural coordinate system, which...
