The formation heritage of Jupiter Family Comet 10P/Tempel 2 as revealed by infrared spectroscopy

► We report chemical composition and spatial properties of parent volatiles in JFC 10P. ► We attempt to distinguish possible formation scenarios. ► We compare water production in its 2010 and 1988 apparitions. ► Our measurements were contemporaneous with a jet-like feature observed at optical wavelengths. ► There is some evidence of a distributed source in the coma (icy grains).
