title: Protein requirements for long term missions.
abstract: A key component of the diet for a space mission is protein. This first part of this paper reviews the reasons for emphasizing protein nutrition and then discusses what the requirements are likely to be. The second part discusses potential advantages of modifying these requirements and describes potential approaches to effecting these modifications based on well established ground based models.
