Beskrivning : Cover Space travel and Voyager two observatory phase begins June 5, 1981.
While passing behind Saturn (as viewed from Earth), Voyager 2 probed Saturn`s upper atmosphere with its radio link to gather information on atmospheric temperature and density profiles. Voyager 2 found that at the uppermost pressure levels (seven kilopascals of pressure), Saturn`s temperature was 70 kelvins (−203 °C), while at the deepest levels measured (120 kilopascals) the temperature increased to 143 K (−130 °C). The north pole was found to be 10 kelvins cooler, although this may be seasonal (see also Saturn Oppositions).
