And what country can preserve its liberties if their rulers are not warned from time to time that their people preserve the spirit of resistance? Let them take arms. The remedy is to set them right as to facts, pardon and pacify them. What signify a few lives lost in a century or two? The tree of liberty must be refreshed from time to time with the blood of patriots and tyrants.

Dark Slope Streaks Split on Mars : What is creating these dark streaks on Mars? No one is sure.
Candidates include dust avalanches, evaporating dry ice sleds, and liquid water flows. What is clear is that the streaks occur through light surface dust and expose a deeper dark layer.
Similar streaks have been photographed on Mars for years and are one of the few surface features that change their appearance seasonally. Particularly interesting here is that larger streaks split into smaller streaks further down the slope.
This image was taken by the HiRISE camera on board the Mars-orbiting Mars Reconnaissance Orbiter (MRO).
how many billions is it going to cost me to find out?
