The answer, in short, is that Cassini’s rocket fuel is almost depleted. Once its fuel tanks run dry, NASA will no longer be able to control the spacecraft’s trajectory, and it would become a derelict, bearing radioactive Plutonium-238 in its electrical generator system.\u003c/p>\n\u003cfigure id=\"attachment_1586255\" class=\"wp-caption aligncenter\" style=\"max-width: 800px\">\u003cimg loading=\"lazy\" decoding=\"async\" class=\"size-medium wp-image-1586255\" src=\"https://ww2.kqed.org/science/wp-content/uploads/sites/35/2017/04/enceladus-tigerstripes-nasa-jpl-caltech-ssi-lpi-800x533.jpg\" alt=\"Long, deep crevasses at Enceladus' southern polar region--dubbed "Tiger Stripes"--are the site where water vapor plumes erupt through the moon's icy crust.\" width=\"800\" height=\"533\" srcset=\"https://cdn.kqed.org/wp-content/uploads/sites/35/2017/04/enceladus-tigerstripes-nasa-jpl-caltech-ssi-lpi-800x533.jpg 800w, https://cdn.kqed.org/wp-content/uploads/sites/35/2017/04/enceladus-tigerstripes-nasa-jpl-caltech-ssi-lpi-160x107.jpg 160w, https://cdn.kqed.org/wp-content/uploads/sites/35/2017/04/enceladus-tigerstripes-nasa-jpl-caltech-ssi-lpi-768x512.jpg 768w, https://cdn.kqed.org/wp-content/uploads/sites/35/2017/04/enceladus-tigerstripes-nasa-jpl-caltech-ssi-lpi-1020x680.jpg 1020w, https://cdn.kqed.org/wp-content/uploads/sites/35/2017/04/enceladus-tigerstripes-nasa-jpl-caltech-ssi-lpi-1180x787.jpg 1180w, https://cdn.kqed.org/wp-content/uploads/sites/35/2017/04/enceladus-tigerstripes-nasa-jpl-caltech-ssi-lpi-960x640.jpg 960w, https://cdn.kqed.org/wp-content/uploads/sites/35/2017/04/enceladus-tigerstripes-nasa-jpl-caltech-ssi-lpi-240x160.jpg 240w, https://cdn.kqed.org/wp-content/uploads/sites/35/2017/04/enceladus-tigerstripes-nasa-jpl-caltech-ssi-lpi-375x250.jpg 375w, https://cdn.kqed.org/wp-content/uploads/sites/35/2017/04/enceladus-tigerstripes-nasa-jpl-caltech-ssi-lpi-520x347.jpg 520w, https://cdn.kqed.org/wp-content/uploads/sites/35/2017/04/enceladus-tigerstripes-nasa-jpl-caltech-ssi-lpi.jpg 1200w\" sizes=\"(max-width: 800px) 100vw, 800px\">\u003cfigcaption class=\"wp-caption-text\">Long, deep crevasses at Enceladus’ southern polar region–dubbed “Tiger Stripes”–are the site where water vapor plumes erupt through the moon’s icy crust. \u003ccite>(NASA/JPL-CalTech/SSI/LPI)\u003c/cite>\u003c/figcaption>\u003c/figure>\n\u003cp>With the possibility that some form of life exists on at least one of Saturn’s moons, NASA is opting to safely destroy Cassini rather than risk it crashing onto a life-bearing world.\u003c/p>\n\u003cp>In fact, Cassini’s initial launch from Earth about 20 years ago raised protests from some, who felt that the risk of a launch explosion that would spread Plutonium through Earth’s atmosphere was unacceptable.\u003c/p>\n\u003cp>Fortunately the launch was a success.
