>It is believed that Europa has an outer layer of water around 100 km (62 mi) thick

http://en.wikipedia.org/wiki/Europa_(moon)

Damn space, you scary! A body of water that's 62 miles deep.

>you will never explore Europes creepy ocean

[Anonymous No.6379035]

Considering there used to be 3 to 4km of ice above me where i sit atm during the last iceage, that is not so special. And antarctica still has sheets that thick and our planet is red hot compared to europe thata sits out there in the wastes. It gives you perspective of the task at hand if we wanted to explore under there though.

62 miles is ca 100 km.

The deepest we can get on earth is right above 10 km. A couple of kilometres of ice is nothing, dude. 100 km is a lot.

Well, since Jupiter is pretty much a failed star, try to imagine this...

>We detonate many Hydrogen bombs at the poles of Jupiter
>It might cause a chain reaction with it's atmosphere, causing it to ignite into a true star
>Europa melts
>Life flourishes on Europa
>Europa is Earth
>Jupiter is Sol
your face when it may be possible

Jupiter fails to have enough mass to become a sustainable star. Just heating it wouldn't be enough.

wat i dont understand is why that dinky assed moon is the only celestial body in our solar system besides earf - with water.

[Anonymous No.6379086]

>>6379065
not to mention the heat would vaporize all of its own moonz and probably fuckup life on earf

[Anonymous No.6379088]

It's not, if you include ice. Water ice is all over the place.

[Anonymous No.6379097]

>>6379088
but you need water for life and europa is our only real chance for finding et life our solar system. it also frightens me how fucked up venus and mars are. leads me to believe that we are lucky as hell to have life on earf and that something bad will happen to us too. glass-half-empty.jpg

"Observations with the Goddard High Resolution Spectrograph of the Hubble Space Telescope, first described in 1995, revealed that Europa has a tenuous atmosphere composed mostly of molecular oxygen (O2)."
.....guys?

[Anonymous No.6379111]

>>6379104
"One estimate suggests that, given the turnover rate inferred from the apparent ~0.5 Gyr maximum age of Europa's surface ice, subduction of radiolytically generated oxidizing species might well lead to oceanic free oxygen concentrations that are comparable to those in terrestrial deep oceans"
life confirmed

That's not literally what anon meant. He was somewhat exaggerating, as the requirements for life are surprisingly low. There can even be Silicon based life, or some other 2spooky shit

[Anonymous No.6379830]

>>6379056
Holy shit, so Europa could have ice 10-30 kilometers thick. Just the ice thickness alone could be more than Challenger deep.

How the fuck are we going to drill through all that in a reasonable time period and get a signal to the surface?

What's the PSI in Europa?

[Anonymous No.6379890]

>>6379322
Si life is extremely unlikely do to Si physical size and the problems it creates with gas exchange
I guess if your incredibly simple but even then

[Anonymous No.6379899]

Europa's ocean may be 100-200km deep with the pressure at the bottom being 130-260 MPa or 37700 Psi. http://www.ncbi.nlm.nih.gov/pubmed/11541880

Another source says the floor pressure might be at 100 MPa or 14500 Psi.

Comparison: Mariana Trench 15,700 psi

1. Send space probe to Europa with instruments to measure its physical and chemical characteristics.
2. Send another probe to Europa with designer organisms (such as GM bacteria) that are able to undergo rapid changes in genetic makeup in response to environmental pressures
3. ????
4. PROFIT!!!!??

[Anonymous No.6379908]

>>6379906
I'm under the impression that Jupiter's electromagnetic field fucks up instruments sent to Europa.

The same reason why we think there is liquid water on Europa is the same reason we can't visit it.

Just saw the Europa Report (on Netflix) which plays off of that. Not the best acting or highest budget, but has a great lead into a neat ending. And none of that soap opera side story bullshit.

[Anonymous No.6380629]

wtf?

then where are all the europeans living?

[Anonymous No.6380630]

Yeah good flick. Much less Hollywood science than typical. I like how they incorporated radioactive materials into the composition of the organisms to explain how they could operate at without many external sources of heat available.

read 2001 and 2010, a space odyssey by Arthur C. Clarke for the original take on it.

True. In the movie the life is spotted near cracks in europa's ice where liquid water meets the surface from the contractions jupiters gravity causes. Kinda like refueling on on some radiation till the next fissure.
