Cassini Spacecraft Finds Ingredient of Household Plastic on Titan


NASA’s Cassini spacecraft has detected propylene, a chemical used to make food-storage containers, car bumpers and other consumer products, on Saturn’s moon Titan.

This is the first definitive detection of the plastic ingredient on any moon or planet, other than Cheap Jordans Sale Earth.

A small amount of propylene was identified in Titan’s lower atmosphere by Cassini’s composite infrared spectrometer (CIRS). This instrument measures the infrared light, or heat radiation, emitted from Saturn and its moons in much the same way our hands feel the warmth of a fire.

Propylene is the first molecule to be discovered on Titan using CIRS. By isolating the same signal at various altitudes within the Wholesale NFL Jerseys lower atmosphere, researchers identified the chemical with a high degree of confidence. ray ban outlet Details are presented in a paper in the Sept. 30 edition of the Astrophysical Journal cheap jerseys Letters.

“This chemical is all around us in everyday life, strung together in long chains to form a Perisi plastic called polypropylene,” said Conor Nixon, a planetary scientist at NASA’s Goddard Space Flight Center in Greenbelt, Md., and lead author of the paper. “That plastic container at the grocery store with the recycling code 5 on the bottom — that’s polypropylene.”
