The ideas of deep-space human exploration, interplanetary travel, and space civilizations are becoming a reality. However, numerous hindrances remain standing in the way of accomplishing these feats, one of which is space ionizing radiation. Space ionizing radiation has become the most hazardous health risk for long-term human space exploration, as it can induce chromosomal damage and epigenetic changes. The Minerva mission aims to demonstrate cutting-edge technology to inhibit DNA damage against deep-space radiation exposure by using genetic modification. The concept of the experiment is to transform a creature with radiation intolerance into a transgenic organism that is radiation-tolerant. In this mission, () will be genetically engineered with a protein-coding gene associated with DNA damage protection called damage suppressor (Dsup). Dsup is a nucleosome-binding protein from the tardigrade that has a unique ability to prevent DNA damage. This paper describes the feasibility of Minerva CubeSat, which will venture out to cis-lunar orbit with a biosensor payload capable of sustaining and culturing under space environment conditions for 4 months. The mission will set in motion a paradigm shift corresponding to future space medicines and how they will be developed in the future, introducing a platform suitable for future experiments in the fields of space biology. Ultimately, the paramount objective of Minerva will be to test the limits of genetic engineering and incorporate it into the arduous journey of human perseverance to overcome the boundaries of space exploration-a vital step in making Mars colonization safe.
深空人类探索、星际旅行和太空文明的构想正逐渐成为现实。然而,要实现这些壮举仍存在诸多阻碍,其中之一便是空间电离辐射。空间电离辐射已成为长期人类太空探索中最危险的健康风险,因为它会诱发染色体损伤和表观遗传变化。密涅瓦任务旨在展示通过基因改造来抑制深空辐射暴露所致DNA损伤的前沿技术。该实验的理念是将一种对辐射不耐受的生物转化为耐辐射的转基因生物。在此次任务中,()将通过与名为损伤抑制因子(Dsup)的DNA损伤保护相关的蛋白质编码基因进行基因工程改造。Dsup是一种来自缓步动物的核小体结合蛋白,具有防止DNA损伤的独特能力。本文描述了密涅瓦立方星的可行性,它将携带一个能够在太空环境条件下维持和培养()4个月的生物传感器有效载荷前往地月顺行轨道。该任务将推动未来太空医学以及未来如何发展太空医学的范式转变,引入一个适合未来太空生物学领域实验的平台。最终,密涅瓦的首要目标将是测试基因工程的极限,并将其纳入人类坚韧不拔地克服太空探索边界的艰苦征程——这是使火星殖民安全的关键一步。
