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 a...
Indications and counterindications for applying different versions of closed ecosystems for space and terrestrial problems of life support [0.03%]
不同版本的封闭生态系统在空间和地面载人生命保障系统中应用的正反面因素分析

The uniqueness of the space radiation field creates specific problems in the evaluation of hazards to men and materials. Comprehensive measurements of all physical parameters are necessary but not sufficient. Particular attention has to be ...
Comparison of measured cosmic ray LET spectra with models and predictions [0.03%]
宇宙射线LET能谱的测量与模型预测对比研究

W Heinrich et al.
Radiation effects of cosmic ray nuclei are generally described as a function of the particle LET. For a large number of space missions LET spectra have been measured and models have been developed to calculate these spectra that include the...
