APOD: Noodle Mosaic of Saturn (2017 Jul 28)

Postby APOD Robot » Fri Jul 28, 2017 4:10 am

Image Noodle Mosaic of Saturn

Explanation: On April 26 the Cassini spacecraft swooped toward Saturn on the first of its Grand Finale dives between Saturn and rings. In this long, thin, noodle mosaic, a rapid series of 137 low resolution images captured by Cassini's wide-angle camera track its progress across the gas giant's swirling cloud tops. The mosaic projection maps the arc along Saturn's atmospheric curve on to a flat image plane. At top, the first mosaic panel is centered at 90 degrees north, about 72,400 kilometers above Saturn's dark north polar vortex. As the mosaic progresses it narrows, the pixel scale shrinking from 8.7 kilometers to 1 kilometer per pixel. For the last panel, the spacecraft is 8,374 kilometers above a region 18 degrees north of Saturn's equator. Frame orientation changes near the bottom as Cassini rotates to maneuver its large, dish-shaped, high-gain antenna forward, providing a shield before crossing Saturn's ring plane.

The Amiga had a paint program... Dpaint V. It had a "brush mode"... looked a bit like that...

Interesting concept, but would like to see the other frames the same size....

Interesting thread!. Cassini knit a "Needle" mosaic. :wink:

We should be having a discussion about the 70 pounds of plutonium that will soon be injected into Saturn's atmos(bio?)phere. After all, we were so careful to keep it out of our own planet's biosphere, yes?

We've been over this before, yes?

If this APOD had shown the seventh planet instead of the sixth, we'd know what that large hole was.

I'm wondering what that speck is at the upper left of the first frame.

It's interesting that they rotated Cassini with the high-gain antenna forward when passing the ring plane. For self-protection? Bah! I think they're hoping to catch a snowball with it.
