I think mars is one of those places where if we ever want to get there we will have to come up with a first mission that doesn't pass current safety standards.

I think mars is one of those places where if we ever want to get there we will have to come up with a first mission that doesn't pass current safety standards. I think it's such a big undertaking that to plan for all circumstances wouldn't allow the mission to happen for a long time. Thing's like no rescue if something went wrong and only accounting for one launch window back to earth,
