The project is an attempt to understand the issues involved in building automated real-time advisory systems to improve the conduct of science in remote laboratory settings. This is an important problem, as examples of these situations can be found throughout aerospace. A knowledge-based approach is used to facilitate real-time

These experiments are typically costly to devise and build, and often difficult to perform. Further, the space laboratory environment is unique, ever-changing, hectic, and therefore stressful. The environment requires quick, correct reactions to events over a wide range of experiments and disciplines, including ones distant from an astronaut's main science specialty. This suggests the use of advanced techniques for data collection, analysis, and decision-making to maximize the value of the research performed. PI-in-a-Box aids astronauts with "quick look" data collection, reduction and analysis, and also with equipment diagnosis and troubleshooting, procedural reminders, and suggestions for high-value departures from the pre-planned experiment protocol. The astronauts have direct access to the system, which is hosted on a portable computer in the Spacelab module. The system is in use on the ground for mission training, and has been delivered to NASA for in-flight use on the Space Life Sciences (SLS) 2 Shuttle mission scheduled for August, 1993.

Together, they allow diagnosis of data-collection problems, hypothesis monitoring and formulation (limited to an analysis of interestingness in the initial system), determination and scheduling of the experiment's steps, and general-purpose help for the astronaut-user.

There is a keen interest in the MUOS data rate capacity as it relates to the available system bandwidth. A set of wide-band code-division multiple access (WCDMA) waveforms will be used to share bandwidth among users and so multiple access interference (MAI) must be considered in evaluating system capacity.

The observations were consistent with a possible large-scale vortex structure in a bright streamer, in which cooler gases revolved about a hotter core.
