Hi! So I've been trying to find the answer through web surfing but can't seem to get a clear answer.

How many people are needed for a "standard" space flight? And how is this number of people determined?

The specific mission I have in mind is one where humans and raw or finished goods get back and forth from an asteroid.

So far I've seen the number range between 2 and 6. I would appreciate further and more knowledgeable insight!

Thanks!

Seems two is the minimum from a safety perspective. More would be dependent on missions to be performed and the capacity of the vessel.

To my knowledge, there isn't a specific answer to your question. It depends.

Just guessing, but a Commander, a pilot, whose specialty is flying the ship. Can the Commander or pilot act as navigator? For long term flights, engineering specialist for the propulsion and life support. Mission specialist for the payload. The Commander can probably back up the others in a pinch. Someone should also be cross-trained to paramedic level.

I guess it would depend on the mission and the type of vehicle involved The Apollo moon landing missions were a crew of 3 a Commander ,a CSM pilot and a LEM pilot. During the shuttle era a typical crew consisted of a Commander, a pilot, two mission specialist and anywhere from 1-4 "Payload Specialist" so it really was determined by the individual mission.
