Randy, I realise that having an intelligent conversation with bigbrain is frustrating. But regardless of that, could you please tone down the name-calling. It's unbecoming and reflects more poorly on you than anyone else.

"Cassini-Huygens has now looped around the Sun twice. On the first loop it flew close behind Venus in its solar orbit, where it "stole" some of the planet's orbital momentum on April 26, 1998. The next loop provided a second flyby of Venus, on June 24, 1999, and one of Earth, on August 18, 1999. Given these three "gravity assist" boosts, Cassini-Huygens finally had enough orbital momentum to reach the outer solar system. One last gravity assist from Jupiter on December 30, 2000 gave Cassini-Huygens the final thrust of energy it needed to project itself all the way to Saturn".

Do Big NASA Buffoons think Cassini is linked to the sun with a wire like in the throwing of the hammer?

This is silly even by your standards.
The gravity sling has been explained to you by Dave and others -- how did you learn to write when you evidently can't read?
I suggest that before you make yourself look even more like an escaped bedlamite, you apply yourself toward learning a little. Then, maybe, you'll know what you're talking about.
And yes, it was linked by a wire; a wire called "Gravity."

Ah Sputnik, that takes me back.

Sputnik and The Dawn of the Space Age
History changed on October 4, 1957, when the Soviet Union successfully launched Sputnik I. The world's first artificial satellite was about the size of a basketball, weighed only 183 pounds, and took about 98 minutes to orbit the Earth on its elliptical path. That launch ushered in new political, military, technological, and scientific developments. While the Sputnik launch was a single event, it marked the start of the space age and the U.S.-U.S.S.R space race.
The story begins in 1952, when the International Council of Scientific Unions decided to establish July 1, 1957, to December 31, 1958, as the International Geophysical Year (IGY) because the scientists knew that the cycles of solar activity would be at a high point then. In October 1954, the council adopted a resolution calling for artificial satellites to be launched during the IGY to map the Earth's surface.
In July 1955, the White House announced plans to launch an Earth-orbiting satellite for the IGY and solicited proposals from various Government research agencies to undertake development. In September 1955, the Naval Research Laboratory's Vanguard proposal was chosen to represent the U.S. during the IGY.
The Sputnik launch changed everything. As a technical achievement, Sputnik caught the world's attention and the American public off-guard. Its size was more impressive than Vanguard's intended 3.5-pound payload. In addition, the public feared that the Soviets' ability to launch satellites also translated into the capability to launch ballistic missiles that could carry nuclear weapons from Europe to the U.S. Then the Soviets struck again; on November 3, Sputnik II was launched, carrying a much heavier payload, including a dog named Laika.
I was aboard a heavy cruiser -- USS Salem, CA 139 -- my first ship. I got to hear the orbiter's signal in the radio shack. Not very impressive in this day & age, but at the time it was the most exciting beeping noise I'd ever heard.
Woah, filthy, You were on the Salem, Sputnik orbited, and in order to hush up the crew hearing the signal, the Salem was decommissioned 15 months later at the secret request of the Soviet government in exchange for some Ukranian wheat.

And then the slowest leg of the journey, the 1,279-day trip of 523 MM between Jupiter and Saturn, averaging just 17,045 MPH.
What has slowed down so drastically Cassini's speed in the last part of its trajectory?

Filth, you don't want to start this. I got caught up in the whole "Venus has hands" fiasco that ran for at least five pages.
Now the obvious trollish behavior now dictates that he will draw a parallel with the wire and start asking how long the tether is so that he can scoff at the strawman and claim that you will say that the probe will be jerked to a halt at the end of the wire. |

I'm impressed bigbrain. You actually managed to produce a formula for gravitational attraction.

So can a monkey, Doc. But, like bigbrain, he doesn't understand it or it's application. |
