Really Rocket Science

Today marks ten years since the Cassini spacecraft arrived at Saturn. The image above is one of my personal favorites (similar images also available via BigBangPrints.com).

The team of scientists at Cassini have selected their own “top 10” list of images. More importantly, their list of the top ten discoveries is far more impressive…

1. The Huygens probe makes first landing on a moon in the outer solar system (Titan)
2. Discovery of active, icy plumes on the Saturnian moon Enceladus
3. Saturn’s rings revealed as active and dynamic — a laboratory for how planets form
4. Titan revealed as Earth-like world with rain, rivers, lakes and seas
5. Studies of the great northern storm of 2010-2011
6. Radio-wave patterns shown not to be tied to Saturn’s interior rotation as previously thought
7. Vertical structures in the rings imaged for the first time
8. Study of prebiotic chemistry on Titan
9. Mystery of the dual bright-dark surface of Iapetus solved
10. First complete view of the north polar hexagon and discovery of giant hurricanes at both of Saturn’s poles

I love the preview of what we can expect in the coming years…

What if Saturn was only a million kilometers away? The gravity would kill us all.

Saturn’s rings were created using Voyager data and Cassini Data, and tables from the IAU, and NASA Interestingly enough, the Voyager data and Cassini data did NOT completely match each other. More interestingly, the differences between the two data sets were not consistent along the ring, specifically the small Gaps along the rings are inconsistent between Voyager and Cassini. There are 3 conclusions I can reach from this,
1. the data is simply not perfectly accurate,
2. I interpreted the data incorrectly,
3. the Rings have actually changed a bit between voyager and cassini.

To create the rings, I interpolated between the two data sets, so the rings are a mix between Voyager and Cassini data, there are multiple textures used, for scattering, translucency, transparency, and color, I think I probably have some of the highest resolution textures in use anywhere on the web(over 19k pixels across).

In Part 1, (the 2d blue print video) the Planets are all correctly scaled to each other, except the SUN.. The Orbits are also all correctly scaled to each other (except the Moon’s). However, the planet size, and the planet orbits are not scaled to each other. The orbital speeds are also all correct relative to one another,

In part 2, The illumination between the moon and Saturn is reasonably accurate, in case you didn’t understand. This is Saturn as Far away as the closest approach mars would get

In Part 3, the meteors ramp up and down in response to going through the very distended outer rings E, and G

The Meteors are Greenish, I’ve actually seen a Number of large daylight meteors, all of them had flashes of green and blue, The velocity and direction they are in the video is accurate to the motion of Saturn in this video

This will.. never never ever happen, ever (probably).

Now’s a really good time to view Saturn.

Of course, the best way to get Saturn up on your wall, permanent-like, is to get a Big Bang Print.

That’s a nice shadow, Saturn. Would look good on my wall.
