3 May 2017
As NASA’s Cassini spacecraft made its first-ever dive through the gap between Saturn and its rings on April 26, 2017, one of its imaging cameras took a series of rapid-fire images that were used to make this movie sequence. The video begins with a view of the vortex at Saturn’s north pole, then heads past the outer boundary of the planet’s hexagon-shaped jet stream and continues further southward.
The first Cassini to explore Saturn was a person. Space probe preparing to crash into ringed planet was named for an astronomical pioneer, by Tom Siegfried, 7:00am, May 15, 2017: here.
50 years ago, an Earth-based telescope spotted Saturn’s fourth ring: here.
