Comment No resupply more frequently than 2+ years (Score 3, Informative) 28

No yu cannot send every 3-6 months because you can launch every two years, when Earth's and Mars' orbit are closely aligned, shortening the distance. Otherwise Mars is too far away and the journey takes too long. Consider in the extreme case where Mars is on one side of the sun and Earth on the other. How long do you think it will take the supplies to reach their location?
