Astronomy Picture of the Day -- All the Water on Europa
NASA ^ | May 24, 2012 | (see photo credit)

Posted on 05/23/2012 9:15:19 PM PDT by SunkenCiv

Explanation: How much of Jupiter's moon Europa is made of water? A lot, actually. Based on the Galileo probe data acquired during its exploration of the Jovian system from 1995 to 2003, Europa posses a deep, global ocean of liquid water beneath a layer of surface ice. The subsurface ocean plus ice layer could range from 80 to 170 kilometers in average depth. Adopting an estimate of 100 kilometers depth, if all the water on Europa were gathered into a ball it would have a radius of 877 kilometers. To scale, this intriguing illustration compares that hypothetical ball of all the water on Europa to the size of Europa itself (left) - and similarly to all the water on planet Earth. With a volume 2-3 times the volume of water in Earth's oceans, the global ocean on Europa holds out a tantalizing destination in the search for extraterrestrial life in our solar system.

Does NASA still have a plan to explore the moons of Jupiter?

We found water. Now we need to process it to make it drinkable for humans, and there we go, asteroid mining.

Hmm, I wonder how the ice fishing is there on Europa?

I love the new science of today.

Lots of “could of’s” and “if’s” and “assuming”, and then we just write the whole article as if it’s all true.

I ‘spose scientists got to eat too. Too bad most are paid out of taxpayer dollars.

We already did that:

Who has time for 2001 jokes?

How about some space idiocy instead?

Sorry. I don't know what could have possessed me.

So if there’s more water on Europa than Earth, can we stop using those damnable ‘water saving’ washing machines which don’t wash clothes?

Front loaders don't use that much water and do a better job of cleaning.
I'm waiting for the new Green urine washer that recycles human waste and
saves water at the same time. And is powered by a bicycle.

Enceladus, in orbit around Saturn, has similar amounts of water, not to mention Saturn’s famous rings. There is more water outside the asteroid belt than within it

If you’re required to use one of those, it’s time to move out of that jurisdiction, or buy a washer somewhere outside it and bring it in.
