在现实中,我们依然用有机成因理论自圆其说,以干酪根热降解生油模式为依据,认为动植物死亡分解埋藏而成矿。但干酪根原子团极其复杂,结构至今没能搞清。土星是太阳系除地球以外有大气层的星球。为了探索它是否有生命迹象,在上个世纪90年代初由美国国家航空航天局、欧洲航天局和意大利航天局共同出资设立对土星系进行空间探测的合作项目。1997年完成飞船制造,并以意大利出生的法国天文学家卡西尼的名字为飞船命名,称“卡西尼”号土
In reality, we still use the organic cause theory to justify ourselves. Based on the kerogen thermal degradation and oil generation model, we believe that the death of animals and plants is decomposed and burial to mineralization. However, kerogen is extremely complicated and its structure has not been elucidated so far. Saturn is the planet of the solar system that has an atmosphere other than Earth. In order to explore whether it has any signs of life, a joint project of space exploration of the Saturnian system was jointly funded by NASA, European Space Agency and Italian Space Agency in the early 1990s. The spacecraft was completed in 1997 and named after an Italian astronomer Cassini named “Cassini”
