Cassini/Huygens: Saturn then TITAN !!
« on: 13/04/2004 19:04:27 »
I am really looking forward to the entry of Cassini to Saturn's orbit and then to the landing of the Hyugens craft on Titan. It will take pictures in various wavelengths and may take some of the surface of this marvelous world a liitle bigger that the Earth with a Nitrogenous atmosphere. Titan is mostly frozen water but more dense than plain water. For some reason the atmosphere is orange. And Titan is said to contain seas of Methane.

Is anyone well prepared to watch this? I found the Cassini Mission on Google. Plenty of pictures... a countdown. July for Saturn and January 2005 for Titan.

Sounds good- i'll definately watch if the mission is successful!
Are there any planned probes to europa? I think that is probably the most exciting place in this solar system other than earth! I wander if they really will send a self heating submarine there to melt its way through the ice...

Yes, Europa is a wonderful mystery. The only other Ocean in the solar system apart from what Mars may have had and perhaps Titan... Netune possibley has massive violent Oceans and Uranus too.

I have enjoyed visualising Europa, walking there the submarine thing... I have not heard of a mission. Europa is smaller than Titan and has no atmosphere. It's surface is like a pole on Earth and it's treasure is inside. Europa was found to have sulphuric acid on the surface. Once in the explorer would need a relay to the surface that went thru water.

I think Titan has more indeed! Surface oceans, mountains, atmoshere similsr to Earth's in pressure and content, the diameter, gravity, Saturns gravity influence...

Hyugens will test for dust and will view in all spectrums. You can read about it from the NASA site.

does anyone know how thick the ice layer on europa is?? do we have estiamtes??  I mean are we talking 20 feet, 200 feet, 20 miles, 200 miles?? thats always been a question of mine.

I think it is, saturn.jpl.nasa.gov/index.cfm or just up to .gov. I have a picture from an artist describing one Hyugens experiments, how shall I insert it? The actual components... are depicted. Cassini reaches Phoebe June 11.

I read briefly that europa has open areas exposed to space, ie liquid water exposed. But I could not tell the ice thickness details, 120 K?

With regards to the entry of Cassini to Saturn's orbit and then to the landing of the Hyugens craft on Titan....Count me in....I'll be there...I love spacey stuff !!...do you think they'll have 'ring side seats'....(sorry...did I really say that ?)

I think they said the ice layer is between 10 miles and 100 miles thick, with the posibility of liquid water underneath being heated by hydrothermal vents. If there's water and a heat source, there's chance for life!
Although how the hell they are going to have enough energy to get a sub to melt through (possibly) 100 miles of ice is a mystery. Its gotta carry a hellava lot of uranium...

Perhaps I should have bought it but I still saw briefly in a magazine that there are places on Europa where the ice breaks open revealing the liquid water to the open space and I suppose a vacuum. It makes sense for the surface of that sattelite is newish and smooth, uncratered.

Well Mars lost it's atmosphere due to a lck of gravity and solar wind. Venus has a tail like a comet from solar wind too but has stronger gravity and much more gas. Perhaps Europa's water vapour refreezes fast or just doesn't have enough energy to get away.

Cassini is only a couple of months away now, already it's sending back some spectacular pictures if Saturn....one with two massive storms colliding and becoming one....it's getting exciting..

Okay, to put you out of your misery. When they first designed the module and made space and weight allocations, technology was significantly less advanced than it was by launch date with the effect that there was a degree of over-allocation.

I happened to be at a talk in Cambridge University given by one of the designers. At a loss for anything else to put in the module to take up the space and weight he decided to include a CD containing the scanned signatures of a few people from mother earth. I signed up, as did Shibley (one of the original co-presenters of Naked Scientists - he's the guy at the bottom of the screen - http://www.thenakedscientists.com/html/who_we_are.htm)

What do you then, Titan's gravity must be much less than expected, but the thickness of the atmoshpere may be as well. I am wishing for some surface pictures. The parachute may still be the right size compared to load...

I wonder what the Titanscape looks like? Perhaps there is life in the methanous oceans. How does methane form without life? Perhaps there is liquification under the surface due to ice mass, weight.
 
Why do you think it is that the solar wind and coronal mass ejections have not blown away the small world's atmosphere? The gravity of Saturn?

Methane, and many other organic molecules (including amino acids) can form without intervention from organisms - all that is required are the correct elements, which is why interstellar gases contain methane and even amino acids.

Cool story, but it seems so outlandish on a planetary probe, that they were filling up space with memorabilia. I can remember fighting for a few grams of mass, and I used custom fasteners to save the thickness of a CD.

How presumptuous of us to assume that other lifeforms would all require liquid water simply because we do.
