The problem is, the opening to the oven is about the thickness of a pencil lead. The Martian soil is proving to be much clumpier -- cemented, in scientific terms -- than expected.

One of the types of ice discussed in the article was hair ice—long, thin strands of ice that grow under quite specific conditions. The only problem is that a new study shows the theory put forth at the time—that gas pressure pushes the water out—isn’t correct... (click the link above to read more).
