Short answer: ISS crew typically stay about six months, but missions can extend to around a year in some cases. Recent reports show both standard six-month stays and notable longer-duration missions of up to about a year when operational needs require it.[2][7][9]
Details:
- Typical missions: ~180 days (roughly six months) to maximize science return while managing crew health.[7][9]
- Longer stays: Some crews have extended to 9–12 months due to scheduling, vehicle readiness, or mission-specific goals; historic long-duration examples include nearly a full year for certain expeditions.[9][2]
- Records and context: While the standard is six months, spaceflight history includes multi-hundred-day stints to study long-term microgravity effects, informing future deep-space missions.[2][9]
Illustration idea: a simple timeline showing typical six-month missions with occasional extensions to nine or twelve months during certain expeditions.
If you’d like, I can pull the latest verified figures and provide a brief, sourced update with a chart.[7][2]
