Ice Exposed in New Craters
A study reported in the journal Science in September 2009, shows that some newly formed craters have excavated clean, water ice from just below the surface in five locations on Mars. After a short time, the ice disappears, subliming into the atmosphere. The ice is only a few feet deep. The ice was confirmed with the Compact Imaging Spectrometer (CRISM) on board the Mars Reconnaissance Orbiter (MRO). The ice was found in a total of 5 locations. One of the locations (Site 5) is in the Diacria quadrangle at about 46° N, 182° E (Arcadia Planitia). This discovery is significant because it shows the presence of subsurface ice at latitudes further south than expected and proves that future colonists on Mars will be able to obtain water from a wide variety of locations. The ice can be dug up, melted, and then taken apart to provide fresh oxygen and hydrogen for rocket fuel. Hydrogen is the powerful fuel used by the space shuttle main engines

“Will lovely, lively, virginal today
Shatter for us with a wing’s drunken blow
This hard, forgotten lake haunted in snow
By the sheer ice of flocks not flown away!”

We must all stop dying in the little ways,
in the craters of hate,
in the potholes of indifference....”
