The joint European/US Spacelab Mission I, scheduled for October 1983 for a 9 day lasting Earth-orbiting flight, provides a laboratory system for various disciplines of science, including exobiology. On the pallet, in the experiment ES 029 "Microorganisms and Biomolecules in Space Hard Environment" 316 dry samples of Bacillus subtilis spores will be exposed to space vacuum and/or selected wavelenghs of solar UV radiation. After recovery action spectra of inactivation, mutation induction, reparability and photochemical damage in DNA and protein will be determined. The results will contribute to the understanding of the mechanism of the increased UV sensitivity of bacterial spores in vacuo and to a better assessment of the chance of survival of resistant life forms in space and of interplanetary transfer of life.
欧洲/美国联合进行的太空实验室任务I计划于1983年10月进行为期9天的绕地球轨道飞行，它为包括外生物学在内的各种科学学科提供了一个实验室系统。在实验ES 029“太空硬环境中的微生物和生物分子”的托盘上，316个枯草芽孢杆菌孢子的干燥样本将被暴露于太空真空和/或选定波长的太阳紫外线辐射下。在恢复后，将测定DNA和蛋白质中失活、突变诱导、可修复性和光化学损伤的作用光谱。这些结果将有助于理解细菌孢子在真空中紫外线敏感性增加的机制，并更好地评估抗性生命形式在太空中的生存机会以及生命在行星间转移的可能性。
