Hvis Cassini blev efterladt til at suse gennem rummet, kunne den v\u00e6re styrtet ned p\u00e5 en af Saturns m\u00e5ner, s\u00e5som den isd\u00e6kkede Enceladus. Det ville v\u00e6re d\u00e5rlige nyheder, da h\u00e5rdf\u00f8re mikrober fra Jorden muligvis havde f\u00e5et en tur med Cassini og dermed kunne blive efterladt p\u00e5 m\u00e5nen.

Huygens landede p\u00e5 Titan og opdagede, at m\u00e5nen minder meget om, hvordan Jorden s\u00e5 ud for l\u00e6nge siden, f\u00f8r der opstod liv her.<\/p>\n<p>Cassini bes\u00f8gte derefter andre af Saturns m\u00e5ner, s\u00e5som Iapetus, der har en stor bule hele vejen rundt om midten; Hyperion, der ligner en k\u00e6mpe svamp; og Mimas, der har et k\u00e6mpe krater, der f\u00e5r den til at ligne D\u00f8dsstjernen fra Star Wars!<\/p>\n<figure class=\"wp-block-image size-large\" data-width=\"1920\" data-credit=\"NASA\/JPL-Caltech\" data-detail-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Images\/2017\/09\/Eight_of_Cassini_s_scientific_instruments_were_used_during_its_grand_finale\" data-licence=\"ESA Standard Licence\" data-licence-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Terms_and_conditions_of_use_of_images_and_videos_available_on_the_esa_website\"><img decoding=\"async\" style=\"max-width: 100%; height: auto;\" src=\"https:\/\/www.esa.int\/var\/esa\/storage\/images\/esa_multimedia\/images\/2017\/09\/eight_of_cassini_s_scientific_instruments_were_used_during_its_grand_finale\/17894536-2-eng-GB\/Eight_of_Cassini_s_scientific_instruments_were_used_during_its_grand_finale.jpg\" alt=\"Eight of Cassini\u2019s scientific instruments were used during its grand finale\" \/><figcaption>Otte af Cassinis videnskabelige instrumenter blev anvendt under missionens afsluttende fase<\/figcaption><\/figure>\n<p>De m\u00e5ske mest sp\u00e6ndende opdagelser blev gjort om m\u00e5nen Enceladus.

Forskere har unders\u00f8gt dette vand og mener, at havet kunne indeholde de kemikalier og den energi, der er n\u00f8dvendige for enkle livsformer! En fremtidig mission kunne give et sikkert svar. Missionsplanl\u00e6ggerne er allerede i gang med at forberede den n\u00e6ste generation af robotudforskere.
