It's my moon. I own it!

Larger than the planet Mercury, Ganymede is one of four moons discovered by Galileo in 1610, easily visible in small telescope and large binoculars. The subsurface ocean confirmed by Hubble is believed to be at least 60 miles thick, containing more water than all of Earth's ocean's combined.
As such, Ganymede joins a growing list of planets and moons in Earth's solar system, including Jupiter's moon Europa and Saturn's moon Enceladus, that are known to harbor vast reservoirs of liquid water.
The latest findings using the Hubble Space Telescope build on earlier observations by NASA's Galileo spacecraft that showed Ganymede has a magnetic field generated by an iron core and two bands of aurora that are created when electrically charged particles captured in the field crash into the moon's extremely thin oxygen atmosphere.

It's my moon. I own it!

As the illustration shows, this moon is larger than our own. With ice to land and take off from, it can’t be a remote or automatic rocket with our technology and a six year manned mission for that alone would be impractical.
Spectrometer reflections have shown it as water, so even if it has other chemicals in it they can be separated. With a number of moons out there having water, that supports work in the asteroid belt without the lift needed to bring water from earth.
The speed (fuel and power) needed in kilometers per second to leave earth is 11.2 kilometers per second. On Ganymede it is a fourth of that requiring 2.7 km/sec. Easier lift off to orbit and then travel with cargo of water where needed.
Additionally the energy needed to escape the gravity well of the sun to and from the asteroid belt to Jupiter is less than half as from earth to the asteroid belt.
Distance would be more a factor of time once escape or approach velocity is reached.
Our species could be gone tomorrow if we have no self sustaining outposts off planet. So it takes 500 years — let’s start next Monday.
If my last name was Ganny and I wanted to market a micro brew ale...I’d call it “Gannymead” or “Ganny’s Mead”( Marcas Registradas pending)
Good post, and I strongly concur.
We used to have a representative government that reflected the dreams and aspirations of a people and not the ideology of a leftist few.
We could dream of going to the moon as we dreamed of such when I was a youngster. We dreamed and we did it as a people.
Now we dream of taxation and government controls and managed outcomes that keep the cost of keeping us alive minimized.
I liked the former way a lot more than I like what passes for government now.
Kind of blows a big plot point in the old V miniseries.
You’re too late. I laid claim to Ganymede on 2 Feb 2008.
Molon labe.
On no account will a Martian drink a glass of water.
You’ve never seen it, have you ... of course not.
You know why don’t you?
Because of one of the most monstrously conceived and executed interstellar plots ever by the red planet—irradiated fluoridation of the universe’s precious bodily fluids.
Too late...it belongs to:
STONE COLD ZOMBIE SCOURGE
And you know this.
Maybe...but it might be easier to take water from a planet with a breathable atmosphere as well as to gather food from an abundance of protein sources. The V aliens were after more than just water...and the bigger you were, the tastier they viewed you!
Very true.
I was in the ICU following my second triple bypass. I must've still been under the influence of the drugs they used for the anesthesia because I was watching a NATGEO special about Jupiter and the subject of its satellites came up. I was hallucinating about a symbol I thought I saw on the screen that stood for Ganymede. When I was discharged in mid-Feb 2008, I read all I could about Ganymede on line, at which time, 2 Feb 2008, I laid claim to the previously unclaimed moon o' Jupiter. I will defend my claim!
There can be only one ruler of Ganymede!
That’s a pretty good story and I can appreciate your hallucinations but I don’t recognize your claim. I don’t want to be harsh but you will not make it within two parsecs of my moon.
Thanks nothingnew. Extra to APoD.
