Poster: Change Awareness for Space Mission Ground Operations Teams

Student: Elias Sinderson

Advisor: E. James Whitehead

Abstract: A number of difficulties faced within large team environments are exacerbated by the unique demands placed on space mission personnel working in ground operations centers. Some of the challenges faced include schedules that shift from one day to the next, an overwhelming burden of data navigation and assimilation, meeting extremely tight deadlines and managing the large communications overhead inherent in large organizations. The successful coordination of multiple teams, to analyze data and produce strategic planning documents and command sequences, rests largely upon their ability to access accurate and timely information. More so than other types of awareness, change plays a central role in this effort.

In this poster session, we present the current state of ongoing work to develop a pervasive, distributed change awareness framework for the 2003 Mars Exploration Rover mission. This framework integrates multiple heterogeneous data repositories and software components to provide situational awareness of the overall mission and real time information about active resources. By utilizing a pub/sub event notification service to distribute information throughout the system bandwidth usage is reduced and event consumers are only alerted to changes they are concerned with. The main user interface component of the framework takes the form of a dashboard like display panel which users can dock at the top or bottom of their screen. This approach allows for a maximum amount of information to be presented in a the most minimally invasive manner. In addition, the widget facilitates easy access to resources that the user has expressed an interest in by simply clicking on the icon that represents the change in question.
