Then also you don't understand: Cassini already went at 101,000 miles per hour, WITHOUT LARGE ROCKET.
Perhaps you don't understand. I'll try to simplify it for you.
A ball is thrown from the driver's side of a moving vehicle traveling at 45 mph. It is thrown out the window not towards direction of travel. The ball is thrown at 20 mph. The velocity of the ball is 20 mph with a 45 mph vectored movement. That is 20 mph foward, 45 mph right movement.
Clear enough for you? |

Thank you so much for ignoring refuting evidence and instead focusing on a single dropped "k".
Now that we've established that the word was "backing", your turn to provide evidence that what you are saying is true. |

Way off base here. Big difference between soft landings and orbital insertions. Also, the shuttle is landed by a human, not by a machine and humans need to have VFR conditions just in case ILS fails.
Orbital insertions and slingshots have a bigger window than soft landings.
Besides a blatant misunderstanding of physics, what evidence do you have that Softimage, Maya, 3D Studio Max, LightWave 3D invent these images for NASA?

Funny, if you try, you could do it from your own vechile.
Have you no idea of basic physics concerning launch from a rotating sphere?
Hint from Copernicus: It moves. Deal with it. |

Leaving aside the orbital intricacies, your main oversight is not realizing that Cassini would slow down as it moved away from the sun. It would not retain its high speed all the way to Saturn. |

The more Cassini goes away from the sun the more gravity force of the sun decreases. |

From the same web page:
quote:
The gravity assist technique was championed by Michael Minovitch in the early 1960s, while he was a UCLA graduate student working during the summers at JPL. Prior to the adoption of the gravity assist technique, it was believed that travel to the outer solar system would only be possible by developing extremely powerful launch vehicles using nuclear reactors to create tremendous thrust, and basically flying larger and larger Hohmann transfers.
Which is why I asked you to include monetary figures for your plan. |

Do you believe that gravity is irrelevant, since it decreases with distance? |

True, but the sun's gravity is pulling on the rocket, and the rocket is not pushing against the gravity (i.e. thrust), the rocket will slow down. Therefore, it needs a larger inisal speed then what your claiming. |

George W Bush is made the same way. He is really a CIA CGI figure created to wreak havoc with the free world. See http://www.skepticfriends.org/forum/topic.asp?TOPIC_ID=4783&whichpage=2
for a reference.
