Timeline Builder Assistant

Current human spaceflight requirements limit the number of hours a crewmember can be outside of the habitation unit to 8 hours in a 48-hour period, and 24 hours in a seven-day period. This time must be appropriately balanced to complete science, exploration, and maintenance tasks. Off-days can be used for site transit (traverse), crew rest, or intra-vehicular activities (IVA). The “building blocks” approach to mission design organizes crewmember activities for extra-vehicular activities (EVA) at each investigation site based on the types of tasks that must be completed and the tools required to complete each task. Building blocks colocate payload and crewmember information for timeline construction. Similar tasks or tasks that accomplish similar goals are grouped into blocks and distributed according to EVA requirements for a specified number of days, including allocations for site arrival activities and departure preparations.
