Polar Viking

According to Cybulski [82] Polar Viking explosive with a density of 1.01 has the following rates of detonation depending on the test conditions ...

IV. Nitroglycerine powders. They contain ca. 10% nitroglycerine which is not gelatinized. The density is ca. 1.0. A typical example is Polar Viking. Its sheathed Eq. S. Explosive is Unifrax.

Their power should not be larger than 58-66% of blasting gelatine [7]. Polar Ajax and Polar Viking arc typical representatives of this group of explosives (VoL 111, pp. 466 and 468 respectively). 

From its zenith in Lowell s work of the 1890 s, this vision of Mars declined to its nadir after the Mariner 4 flyby in 1965. Mariner 4 showed a cratered, dusty ball clad in only the most diaphanous of atmospheres— one whose white polar regions were declared to be most likely covered in dry ice (carbon dioxide rather than water). As the data from the Viking landers of the 1970 s proved inconclusive and controversial, the vision of dry, white Mars dominated discussion of the planet for decades.
