EUROPA and SPIFE Demos to JSC Mission Operations Directorate

NASA Ames staff demonstrated how the Extensible Universal Remote Operations Planning Architecture (EUROPA) and the Scheduling and Planning Interface for Exploration (SPIFE) would be used to manage operations plans for the International Space Station (ISS). The demonstration to staff from Johnson Space Center (JSC)’s Mission Operations Directorate (MOD) was prepared based on a benchmark package provided by MOD that included details of 11 days of joint ISS and Shuttle operations, with highly detailed operations plans for four days of the mission. The package included scheduled and unscheduled activities, numerous constraints, ground rules, and flight rules. It covered both crew activities and the coordination of activities between crew and flight controllers on the ground.

The Ames team was provided one month to prepare the plan, followed by a full day of detailed meetings at JSC. Half a day was spent in analyzing the plan using EUROPA and SPIFE; describing how the plan appeared to the user; describing how constraint, flight rule, and ground rule violations appeared and were addressed; and responding to requested changes in the plan. Requested changes—which were not divulged ahead of time—ranged from trivial (move activities) to moderate (add constraints, schedule activities, unschedule activities) to sophisticated (change the resource an activity uses). An additional half-day was spent describing the software architecture and business model, and discussing desired changes to the software.

BACKGROUND: The Extensible Universal Remote Operations Planning Architecture (EUROPA) and the Scheduling and Planning Interface for Exploration (SPIFE) were developed at NASA Ames Research Center, and have both been used for a variety of different mission planning and scheduling applications, as well as demonstrated in advanced technology demonstrations for mission planning and control of autonomous robots and spacecraft.
