Do you know how long are the missions?

Submitted by: Ali Hassan Siddiqui
The ISS missions, called expeditions, usually last about six months. There are three to six crew members on board at all times. A space shuttle crew is typically five to seven crew members. We have carried as few as two and as many as eight at one time, and space shuttle missions have been as short as two days and as long as 18 days.
