Saturn's atmosphere exhibits a banded pattern similar to Jupiter's, but Saturn's bands are much fainter and are much wider near the equator. The nomenclature used to describe these bands is the same as on Jupiter. Saturn's finer cloud patterns were not observed until the flybys of the Voyager spacecraft during the 1980s.
Measure the temperature of Saturn's atmosphere and that of Titan, the largest satellite of Saturn. Determine the structure of the upper atmosphere of Saturn where molecules are expected to be electrically charged and form an ionosphere. Map the thermal structure of Saturn's atmosphere by infrared observations coupled with radio occultation data.
The outer atmosphere of Saturn consists of about 93.2% hydrogen and 6.7% helium. Trace amounts of ammonia, acetylene , ethane, phosphine, and methane have also been detected. As with Jupiter, the upper clouds on Saturn are composed of ammonia crystals, while the lower level clouds appear to be composed of either ammonium hydrosulfide (NH 4 SH ...
Present in the D Ring is a finescale structure with waves 30 km (20 miles) apart. First seen in the gap between the C Ring and D73, [87] the structure was found during Saturn's 2009 equinox to extend a radial distance of 19,000 km (12,000 miles) from the D Ring to the inner edge of the B Ring.
In April of last year, Cassini spent 44 hours staring at Saturn's atmosphere and capturing in-depth images. The mission to Saturn is a joint venture between NASA, the European Space Agency and the ...
An event timer on the probe would initiate activities, while the carrier–relay spacecraft would power up its radio receiver and turn to point its probe-relay antenna to the entry site. The probe would enter Saturn's atmosphere at a velocity of approximately 27 km/s, which is less than the Galileo Probe's velocity of 47.4 km/s. After the entry ...
Astronomers believe the mysterious “magic islands” on Saturn’s moon Titan are honeycomb-like frozen clumps of organic material that fall like snow on the moon.
