This thread was originally made for Dusterbayala.
I`ve been up to a little researching on the moon Europa. Which is one of Jupiter's`s numerous satellites. Its seems to be of great interest to the scientific community. Mostly due to the fact it could possibly have a **possibly** a Ocean of 30km under its 5km icy surface. The moon was recently documented in in 2000 and its experiencing underwater volcano activity. The problem with the exploration, is that the government cut funding after the robot sent to mars was severely damaged and unusable.

If the Icy moon of the Gas giants secrets are revealed it might revolutionize our ideas. Due to its possibility of maintain life in its ocean. They plan to send a satellite to it for a month (due to Jupiter's mass radiation) it will be measuring the shifts in the surface height. Whats your out take on Europa`s value ability to us????

^ I love you, Senb

Anyway...
The most exciting thing about Europa is that the Liquid water layer under the huge Ice crust, may contain Life... This would be amazing in the eyes of the science world. It may only be ameobas but still the possibility of LIFE!
Ok, also.... for those who don't know...
Jupiter has a very large magnetosphere... (which is why it holds soo many satellites.. (they were at 77 and counting last i knew)
But the problem with the very large Magentosphere is that it sucks in and hold massive amounts of radiation. This radiation cause massive amount of corrosion on almost any type of metal.. Hence why setting up a mission is costly and difficult..
The antenna for sending back information must be strong enough to endure these large amounts of radiation as well as to be able to break out of the magnetosphere..
That's a nice pic btw senb... Is that one from Gallelio?


Edit: Oh yeah!
If we do discover the secrets of the gas giants and their satellites, then we might be able to discover other Galaxies like ours and the possibility of maybe even an M-class planet!
Edit#2:
Uhm... just fyi senb... europa was actually discovered in 1610... by gallileo.... he was excommunicated because of it.

^thx Duster I knew it was I forgot that part to put in. Hence the reason that satellite was named Galileo.
So I read up on the discussion between Europa's exploration. I believe their gonna be using Laser altimetry for the first mission. Before they can even consider taking a drill their. They also have a problem with communications from such a vast distance. I believe 10 to 15 degrees is needed to make radio contact with earth. So their gonna have to make a robot capable of preset programs. Unfortunately we don't have the knowledge for that yet *points japan definitely does hehe*

Which is why a united world for space (lol the federation - I'm a dork I know)
Would be ideal!
The sharing of knowledge and personel...
It's just insane to see the amount wasted by political battles...
Not only will they have to wait to make the orbiter, they'll have to make it for the right time frame, to bounce off the other planets and satellite's gravitational pull to make it there!

Thats most definitely true. To bad we cant make a government based on scientific desires. I`m pretty sure we dont need the rantings of idiots that make alot of bullshit promises. Seems like the space federation is not getting the funding it needs. I`ve began to notice that its been steadily decreasing. Tsk tsk looks like another decade before enlightenment.

sad but true.. But anyway to get back on topic


I think that Europa is going to contain a silicate form of life, similar to earth's deep ocean sulpher vent life...
The reason I think this, is, unless there is Phytoplankton (or something similar) how is there oxygen for those possible life forms to thrive on?
Where as there may be sulpher and silicates venting out from fumaroles just like on earth (my terminology may be wrong here... been awhile since oceanography class)

by the way because of the radiation of Jupiter would that increase the temperature of the moon because it seem that it is quite a large distance from the sun or any other major heat source meaning the moon europa is quite hot judging from the distance that it is from the sun

bullet points facts

brightest surface in solar system because of smooth young surface

the surface was known to be water and ice 40 years ago




the core is made of iron and nickel which is covered by a rock shell which has water over it

Not exactly. Radiation isnt exactly a heat source. Europa seems to have formed as any of the jovial planets formed. That would make me more compelled to study it. Since its structure is as such it contains inner volcanoes. Which its been experiencing recent eruptions. Giving that appearance. @ali1238 by any chance did you google that???? :lol:
*looks to duster for her knowledge on the subject*

Hmmm I think i`m gonna make a fusion and fission thread. *spread the science throughout CR so all may accept*

which is ***Believed*** to have water over it... they aren't sure if it's liquid water or slush... judging by the impact craters they are wondering if it's more slush than they origonally thought.

yes i did sorry (could not add much and had to find a way to keep up with you guy and gals)topic sounded interesting better than most because there usually mindless babble i need to edit my first post the pic does not work and most of the information does not show

EDIT: fixed table showing

also the surface of the planet seems very different to the rest as it seems more smooth meaning the moon may be young or the surface is youngand also it seems the moon eurpa had all the primary ingredients for life water, heat and compounds for food also the ice is lost of different colours looking at lots of pics usualy blue or light blue can anyone tell me why , i think it is because of the coarseness and the compounds in the water/ice (correct me if you will)

^I see what your saying ali. Seems CR has steadily been coming closer to turmoil. I think i`ll be the one to create a possible science section. That is something of my dream. I can no longer take repetitive conversations in impudent topics. Might as well ask me what kinda toast I enjoy

It seems Jupiter holds a massive amount of secrets. Europa is definitely interesting. So i`ll ask a hypothetical question. What if the ice caps of Europa were to melt and it became a full ocean planet. Could it possibly maintain its self along with the pull of Jupiter?

it has minimal heat... nothing near what we consider heat... it's temp would deep freeze the pacific ocean in about 5 years. (that's freakin cold!)
They are unsure if there is any type of "food" (that's why we need to explore!)

The Ice streaks on the surface are there because of the contant push / pull of Jupiter's gravity effecting it. it pulls apart the deeply frozen Ice and liquid is **believed** to have gushed out (ice guisers -sp) and then contracts back again to close the gap.

It's just soo freakin cool..


Edit: Senb... how would it melt? what event would occur for it to melt? it's so far away from the sun that that possiblity is next to nil!

i think so because europa and its gravity can maintain the water right now and the ice is not showing and real strain (well it is but not enough to make water gush towards the planet even slightly)because of the water so if the ice were to melt it would mean that the planet (water) may be slightly more expanded at the side that faces the planet jupitor the expansion would change when the planet tilts on it axis

this is pure theory and a small amount of science has been implemented into it


@duster i believe it was a ' what if ' type of question

@Dusterbayala thats why I stated hypothetically speaking. Gotta think outside the box to get my concept. A possible collision at a certain point. Which i`m aware is impossible due to Jupiter's godly gravity, Its like a amoeba ramming a human being.

Well seeing things so far it ***might*** possibly gushing. Seems reasonable but I beleive its -264 degrees Fahrenheit. I`m not positive but volcanic activity should be capable of unfreezing ice.

i think the ice has a very slim chance of melting think 5km of ice that mean he heat will have to travel 35km(water and ice included) to get to the tip of the ice (but the density is quite high compared to the air meaning heat spreads faster) which is only possible if the volcanoes are continuous over years/months and a in abundance but on the other hand i other theory which i dont like as much show that the ice is cracking and the water is not pure in some place and this means heat will travel at different paces causing cracks which would lead to faster melting and gasses may be rising from theses cracks and exsisting cracks producing heat from movment (tiny amounts)

sorry i edit my posts TOO much its hard to fit all my ideas in 1 post
