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...
