  Jet related observables have been some of the most powerful and exciting
probes for understanding the matter produced in ultra-relativistic heavy ion
collisions. Full jet reconstruction was begun at RHIC, and the LHC experiments
have shown the power and kinematic reach of these observables. Here we discuss
the sPHENIX detector and physics program which aims to bring full calorimetric
based jet reconstruction to RHIC in order to explore the temperature dependence
of the strongly interacting Quark Gluon Plasma.
