Discovery of propylene in Titan's upper atmosphere with Cassini CIRS

Cassini's Composite Infrared Spectrometer (CIRS) Team detected a new molecule, propylene (propene), in Titan's upper atmosphere.

Significance: First definitive identification of propylene gas in a planetary atmosphere outside Earth.

Propylene is an important raw material for our chemical industry. It is used to make polypropylene, a durable plastic that is molded into many commercial common items, including food storage containers.
