I think they make their own water ice.
We don't yet understand the relationship between water ice and the reddish tholin colorants on Pluto's surface.”.
Water ice seems to be ubiquitous on its surface, with a mass fraction of 50- 90%, significantly more than in Ganymede as a whole.
In the equatorial part of the celestial body,particles of hydrocarbonate and water ice form a vast area of dunes.
Their spectra indicate that they are made from water ice contaminated by some very dark material, probably complex organic compounds.

Another possible sourceis the outgassing of the primordial CO2 trapped by water ice in Umbriel's interior.
Water ice clouds begin at a level where the pressure is about 2.5 bar and extend down to 9.5 bar, where temperatures range from 185- 270 K.
We don't yet understand the relationship between water ice and the reddish tholin colorants on Pluto's surface.”.
For reasons not yet deciphered, the middle part of thecomet does not contain much carbon dioxide, and thus the water ice in it can warm into vapor.
The actual temperature and distance for the snow line of water ice depend on the physical model used to calculate it and on the theoretical solar nebula model.
Because ice is less dense than water, it floats on the ocean's surface(as does fresh water ice, which has an even lower density).
Water ice might be sublimating(turning from solid to gas) off one of the asteroids' surfaces and reforming as small balls of ice in open space.
We know there are volatiles at the poles on the moon,and quite frankly, that water ice could represent rocket fuel," he said.
Since then(2006), crystalline water ice was also found on, but present in larger quantities and thought to be responsible for the very high albedo of that object(0.7).
So, all solids that possess an appreciable vapor pressure at a certaintemperature usually can sublime in air(e.g., water ice just below 0°C).
The landscape is a rippled mix of color,from the bright whites of water ice to the dark reds and browns of martian dust, and displays a number of interesting phenomena.
Around the coast of Antarctica, the glaciers have flowed out across the sea toform immense masses of floating fresh water ice called ice shelves.
We have known that water ice exists on Mars since 2008, and according to this new research, published in the journal Geophysical Research Letters on Tuesday, NASA is continually discovering more and more of it.
Occasionally, the term snow line isalso used to represent the present distance at which water ice can be stable(even under direct sunlight).
That could potentially make it easier to reach by future astronauts, researchers said, since explorers wouldn't necessarily have to venture into the permanently darkcraters at the moon's poles known to host water ice.
As close to the sun as Mercury is, in 2012,NASA's MESSENGER spacecraft discovered water ice in the craters around its north pole, where regions may be permanently shaded from the heat of the sun.
Using the Near-Infrared Coronagraphic Imager(NICI) installed on the Gemini South Telescope in Chile, the researchers, led by Mitsuhiko Honda at the Kurume University School of Medicine's Department of Physics, found that a circumstellardisk around the star HD 100546 contains water ice grains.
Under the upcoming Artemis mission,NASA plans to land on the Moon's South Pole in order to exploit its water ice, discovered in 2009, both for life support purposes and to split into hydrogen and oxygen for use as rocket propellant.
Unlike Pluto, which is covered with nitrogen and methane ices, the Charonian surface appears to be dominated by less volatile water ice, and also appears to have no atmosphere….
Moreover, it can, by assuming that the water ice is in Chiron's rings, explain the changing intensity of the infrared water-ice absorption bands in Chiron's spectrum, including their disappearance in 2001(when the rings were edge-on).
The budget includes $529 million for robotic trips to Mars, including a mission to return soil samples back to Earth andmap near-surface water ice deposits that could inform future human missions to the red planet.
