This is great news as long as we have women we should never run out of rocket fuel. big_smile

I wish we had a say in where our tax money goes. In this case I would have opted for a Wall mart camera. I think they are holding back magnificent images.

Looks like an asteroid that is tumbling as it goes by to me.

It would not need a rotor to move since the stator is now the rotating element.

#6 Re: Interplanetary transportation » Electron flow within a wire. » 2005-02-07 21:13:32

If you wrap a waterhose around a rotating shaft many times and turn the water on the shaft will start rotating. The same thing will happen with a insulated wire wrapped around a central well balanced rotating shaft if you turn up the amps.

"If we had the Hollywood grade pictures he wants, then he would be whining about "wheres my video!?""

We had them with Galileo. Why not with Cassini?

#8 Re: Interplanetary transportation » Electron flow within a wire. » 2005-02-07 20:00:00

They say electrons flow in a wire like water flows in a garden hose. If this is so then electrons can provide a reaction force within the wire just as water does within a garden hose but this force would be much smaller. It can be proven in an experiment.

I am not talking about Huygens I am talking about Cassini now.

#10 Re: Science, Technology, and Astronomy » Galileo VS Cassini » 2005-02-07 19:25:25

"Errorist why do you keep putting the Cassini Huygens probe down when you really should be applauding its success."

I do applaude the mission. However, the pictures show the true picture. Galileo was magnificent while Cassini is a throwback to the 70s.In my opinion a waste of tax payer money. Unless,they can show me conclusive proof of better photos than Galileo.A picture is worth a thousand words.Don't tell me it is better show me it is better.

#11 Re: Science, Technology, and Astronomy » Galileo VS Cassini » 2005-02-07 16:34:38

Nothing at all looks bad with the lighting it is the closeness and resolution I am talking about here. There is no comparison.
Galileo wins by a landslide. Again, a Wall Mart camera would have done much better.

1 to 30 ratio sounds good to me. It would be like living in the cave man days. You would wake up in the morning in the martian cave and order your women to cook you breakfast and to warm the place up some. However, Prochoice would be out of the question. Prochoice = Murder in Gods book.

#13 Re: Science, Technology, and Astronomy » Galileo VS Cassini » 2005-02-07 13:56:45

Again we are not getting the true picture. Galileo ten years older and having a thousand times better resolution than Cassini. Why are they not showing us better quality pictures than Galileo? The pictures that Cassini should be taking should have better resolution than Galileo had. Are they keeping the better quality photos from us?

#14 Re: Human missions » Finally, a sensible solution to the Hubble debate - ... that we can all agree on...maybe. » 2005-02-05 19:23:03

The heck with this bickering none of it makes sense. Lets get back to the aerogel mirror????

#15 Re: Human missions » Finally, a sensible solution to the Hubble debate - ... that we can all agree on...maybe. » 2005-02-05 04:54:23

"Wouldn't micrometeroids fly right through aerogel? Or at least into it. You'ld want some sort of micrometeoroid resistant coating on the mirror, and a micrometeoroid resistant backing. You could keep telescope mass down by exposing the mirror to space like the James Webb space telescope. Needs a sun shade."

Yes they would get stuck in it like the star dust mission but this would happen to any mirror. Cemical vapor deposition would make it stronger and more reflective.Scientist say it can be accomplished.A huge scope could be built at the space station and would be many times less massive than any scope ever built.Also repairable.

"Using the mirror and cameras built for Hubble is generally a good idea. However, as I said my opinion is that we need to ensure we can service a telescope and keep costs down before launching anything else. This will be the last service of Hubble, it's life will eventually come to an end. Then we should launch a dramatically improved telescope. I would suggest starting with medium Earth orbit (MEO) where it's orbit is stable without using fuel. That would require a manned vehicle that can travel from LEO (where any shuttle would park) to MEO and back. An on-orbit tug with a CEV style capsule could do it, but we don't have it yet. Yes, I would like that vehicle to be reusable as well. Also give it a larger mirror; a single-piece large mirror could be launched on edge to keep aerodynamics down. Russia proposed launching a disk shaped lander for Mars on the side of an Energia. If Russia can do it, can't America? Let the engineers debate whether it's better to side launch like Shuttle-C or on top of an EELV. Do you think astronomers would like a 24 metre space telescope? But we're not ready for that yet, so let's keep Hubble."

Aerogel Mirror!!!

"As for expendable launch vehicles, I see them as short-term work horses. I already submitted a paper to NASA proposing a reusable mini-shuttle space taxi with an expendable external tank, but even that's a stop-gap. I want to see hypersonic spacecraft developed to produce a true spaceplane. I don't think a space elevator will ever be practical for passengers, it takes too many days to get up there. I also proposed a series of small UAVs extending the X-43 program to develop a true SSTO RLV spaceplane. I think they can be achieved. I don't know about cargo, for now we have expendable rockets. We can talk about launch vehicles in another thread."

I agree the Space elevator is to massive but the Pipline to space isn't!

University Of Miami does a lot of research in this area and if a cure is ever found it may come from here.

#20 Re: Science, Technology, and Astronomy » Aerogel telescope mirror » 2005-02-02 21:25:12

I was thinking of building it in many sections on the space station using a reator to make the Aerogel. It would weigh less than 1000 lbs when finished.

#21 Re: Not So Free Chat » McCarthyism - ...will it rise again? » 2005-02-02 19:37:58

I agree. Now what was that about Michigan again? big_smile

#23 Re: Science, Technology, and Astronomy » Aerogel telescope mirror » 2005-02-02 18:34:26

How about building one 1000 feet in diameter in space? In sections of course.

"2nd amendment:A well regulated Militia, being necessary to the security of a free State, the right of the people to keep and bear Arms, shall not be infringed."

How dare they infringe on my right to carry arms on aircraft???
How else am I to protect myself on airplanes? I think I am going to sue them!!!!!!!

#25 Re: Not So Free Chat » A great gift for our children to worry about? » 2005-02-02 17:02:48

The predictions are way off since they don't even take into account India and China using as much electricity or driving cars in the same ratio as we do here in the USA.Figure that into the formula and it will be much worse than they think and it doesn't even mention how big the Ozone hole will become if India and China get industrialized like we are.
