Incredible video reveals views from Nasa's Cassini spacecraft during its first dive into Saturn's rings
Nasa has released a stunning video taken by the Cassini spacecraft showing the view during its first dive into Saturn's rings last month.

It begins with a view of the swirling vortex at the planet's north pole, then heads past the outer boundary of the hexagon-shaped jet stream and beyond.
The movie comprises one hour of observations as the spacecraft moved southward over Saturn on April 26.



'I was surprised to see so many sharp edges along the hexagon's outer boundary and the eye-wall of the polar vortex,' said Kunio Sayanagi, an associate of the Cassini imaging team based at Hampton University in Virginia, who helped produce the new movie.

'Something must be keeping different latitudes from mixing to maintain those edges,' he said.

Toward the end of the footage, the camera frame rotates as the spacecraft reorients to point its large, saucer-shaped antenna in the direction of the spacecraft's motion.

The antenna was used as a protective shield during the crossing of Saturn's ring plane.

As the movie frames were captured, the Cassini spacecraft's altitude above the clouds dropped from 45,000 to 4,200 miles (72,400 to 6,700 kilometers).
As this occurred, the smallest resolvable features in the atmosphere changed from 5.4 miles (8.7 kilometers) per pixel to 0.5 mile (810 meters) per pixel.

'The images from the first pass were great, but we were conservative with the camera settings.
'We plan to make updates to our observations for a similar opportunity on June 28 that we think will result in even better views,' said Andrew Ingersoll, a member of the Cassini imaging team based at Caltech in Pasadena, California.
