However, a variant of the lizard pattern remained in use with the entire French Foreign Legion in the 1960s and by the French Foreign Legion paratroopers until the early 1980s. The French Army continued the use of horizontal lizard patterns until after the Algerian War as it was felt it was too closely associated with the Paratroops Munity that called for French President Charles de Gaulle not to abandon French Algeria. French soldiers in Indochina in the early 1950s wearing the lizard pattern uniforms, which proved quite adequate in the jungle terrain.

The spacecraft came within 175 kilometers (109 miles) of the surface of Enceladus.Įnceladus is 500 kilometers (314 miles) across and has the most reflective surface The others are the volcanoes on Jupiter's moon Io and geysers onĭata for these measurements were taken during Cassini's closest flyby on July 14, 2005. That vapor and dust-sized icy material are coming from the tiger stripes.Įnceladus is on a short list of bodies in our solar system where scientists have found These data also indicate the production of water vaporĪnd ejection of fine material are connected, as they are in a comet. The timing of the craft's ion and neutral mass spectrometer and the cosmic dustĪnalyzer observations seems to indicate the vapor and fine material are originatingįrom the "hot" polar cap region. South polar cap, in which the tiger stripe fractures were found to be among the Cassini's cameras provided detailed images of the "Enceladus and its incredible geology is a marvelous puzzle for us to figure out."Īdding to the already mounting evidence for an active body is the correlation of Brown is a team leaderįor the visual and infrared mapping spectrometer at the University of Arizona, Tucson. Phenomena, but it has done just that," said Dr. It's hard for a body as small asĮnceladus to hold onto the heat necessary to drive such large-scale geophysical Icy moons go, but so very geophysically active. "One of the most fascinating aspects of Enceladus is that it is so very small as To take place over decades or less, the tiger stripes must be very young. Undisturbed, it ages and converts to amorphous ice. As the ice near the poles remains cold and When ice comes out of the "hot" cracks, or "tiger stripes," at the south pole, Two forms on Enceladus: in pristine, crystalline ice and radiation-damaged In 1981, it did not observe the tiger stripes.Ĭassini's visual and infrared mapping spectrometer shows water ice exists in When NASA's Voyager 2 spacecraft flew over the moon's north pole CassiniĪllows scientists to see close up that the brightening is caused by geologicĪctivity.

She is a team member of the Cassini visual and infrared Tiger stripes, which could have been very recently resurfaced," said Dr.īonnie Buratti. "There appears to be a continual supply of fresh, crystalline ice at the Which helped scientists pin down the age of the features.
