早在14年前,许多科学家试图通过分析采到的火星岩石、土壤等,来解开火星生命的秘密。他们通过火星取样,很可能找到活跃的有机体,或者正处在休眠状态。鉴于宇宙辐射都杀不死它们,破坏性可能更强。因此,美国的宇航局还认为,应该防止人类感染火星细菌,免得连抗生素也束手无策,一任病菌在森林、田野四处传播,造成人类像牛群一样成批死于“疯牛病”那种惨状。 As early as 14 years ago, many scientists tried to unravel the secrets of life on Mars by analyzing the collected Martian rocks and soils. They sampled through Mars and were likely to find active organisms or be dormant. Given that cosmic radiation does not kill them, it may be more destructive. Therefore, the United States NASA also believes that it should prevent humans from infecting Mars bacteria, so that even antibiotics are at a loss. Once a disease spreads around the forests and fields, it causes humans to die in batches like cows in the mad cow disease.
