But the domes themselves must also be kept clear of ice that could damage them or make them unstable.

The dwarf planet Ceres contains ice buried beneath an outer crust and researchers have drawn a parallel between the two bodies.

#Ice may explain odd craters on Mars Brown University right Original Studyposted by Kevin Stacey-Brown on August 6 2013brown (US) More than 600 double-layer craters on Mars may have been caused by debris
During these times ice from the polar caps is redistributed into the mid-latitudes of Mars as a layer about 50 meters thick in the same place that we see that the DLES have formed.
This made us think that this ice layer could be part of the explanation for the formation of the unusual DLE second layer.
In the scenario Head and graduate student David Kutai Weiss describe in the journal Geophysical Research Letters the impact blasts through the ice layer spitting rock and other ejecta out onto the surrounding ice.
But because that ejected material sits on slippery ice it doesn t all stay put. The researchers believe the layering occurs
when material near the top of an upraised crater rim slides down the slippery ice and overtops material on the lower slopes.
and a slick ice layer creates the DLES telltale two-layered appearance. I think for the first time
and Head thinking that ice could be a key ingredient for making a DLE. Ice would reduce the coefficient of friction on the slopes of crater rims increasing the likelihood of a slide.
When I did a quick calculation I realized that the landslide wouldn be expected to happen (on crater rims)
unless the ejecta was landsliding on an ice layer Weiss says. The scenario also requires a steep slope on the outside of a crater rim.
The ice model also accounts for other distinctive features of DLES. For example unlike other crater types DLES tend not to have secondary craters surrounding them.
But if that surrounding surface were covered by ice evidence of shallow secondary craters would disappear
when the ice disappeared. The model also appears to explain the locations of DLES at middle

Depending on temperature, these complexes can grow into large water droplets or frozen balls of ice, leading to cloud formation and rain or snow.

Polynyas are regions of open water near sea ice that are kept from freezing by wind and currents that sweep newly formed ice away.

In December astronomers announced hints of watery plumes spurting from Jupiter's large moon Europa potentially giving us a peek into a vast ocean likely to exist beneath its ice.
Europa meanwhile appears to be covered entirely by an ocean sandwiched between a rocky core and a thin ice crust.
Galileo also hints that Europa's ice crust has active plate tectonics which would let nutrients from the surface make their way into the liquid ocean.
and drill through the ice since we don't know for sure if the plumes are fed by it.
and explaining the salty ice grains we see coming out of the surface. The team also found that the southern hemisphere has a stronger gravitational pull than its topography would suggest.
That could be explained by a localised sea sitting beneath 35 kilometres of ice and up to 8 kilometres deep.

#Mini robot space surgeon to climb inside astronauts It could one day answer the prayers of astronauts who need surgery in deep space.
A physical simulation of a comet's impact with a planet shows that the conditions are extreme enough to create amino acids within the comet's ice.
Theoretical studies had suggested that the shock of an impact could rearrange the components of the ice into something more interesting.
and colleagues made model comet ice in the lab containing various amounts of ammonia carbon dioxide and methanol.
Then they shot the ice with a steel pellet travelling at about 7 kilometres a second to simulate the comet smacking into a planet
The goop that remained after the ice was evaporated away was analysed by Price's colleague Zita Martins at Imperial College London who found it contained the amino acids alanine and norvaline.
When this article was published first on 15 september it did not give details of the researcher who detected amino acids in the ice.

#Mega-Canyon Discovered Beneath Greenland Ice Sheet A previously unknown canyon has been discovered in Greenland hidden beneath the ice.
The canyon which is thought to predate glaciation has remained hidden beneath two kilometres of ice for more than four million years.
Considerable effort has been put into collecting bed topography of the Greenland ice sheet recently and there is a lot of data to be processed and interpreted.
I'm sure there are many secrets left to discover beneath Greenland's ice and likewise in Antarctica.
Radio waves of certain frequencies can travel through ice but bounce off the bedrock beneath. So researchers sent down pulses of radio energy of this particular frequency.
This lubricates the ice sheet and therefore determines the speed at which it moves. We think the canyon is an efficient conduit for ice-melt from the glacier.
If you want to model glacial movement â##something that is ever more crucial due to global warming â##then knowing about such topography is very important.

#Dramatic Ice Loss Is Messing With Antarctica's Gravity Just when you wondered if climate change news couldn't get much worse along comes proof that it's affected one of the fundamental forces of nature:

DIRTT is hoping to forestall these problems with the help of their Doom engine-based software named ICE.
We re going to have cost certainty with ICE Jenkins says. The Doom engine is a computer program that can render 2-D blueprints into a 3-D space.
Because the engine is open-source DIRTT was able to adapt it for their own needs--for example ICE melts with other design softwares including Autocad.
An engineer or an architect can use ICE to mock up a room and create a live data set for every aspect of a space including the electrical engineering millwork and piping.
Because of ICE we don't have separate teams of manufacturers trying to coordinate with ordered engineering says Jenkins.

"These limitations hindered scientists'ability to examine the molecular-level structure and dynamics of ice.
That has left gaps in our understanding of the important role that ice plays in the environment,
In 2013, Shultz's lab took a giant step toward removing these limitations by inventing a special apparatus to grow large samples of single-crystal ice.
But selecting a specific face from that ice remained elusive. Shultz credits her most recent breakthrough to simple geometry and trigonometry.
The most common type of ice called Ih or"ice one h,"is made up of water molecules in a hexagonal crystal shape in an orderly,
repeating arrangement called a lattice. Shultz found that by using certain measurements and formulas, she could determine the crystal's lattice orientation as it relates to a surface
