The first flight of the Cosmic Ray Energetics And Mass (CREAM) balloon experiment flew for a record breaking 42 days from McMurdo Station in Antarctica and utilized a Calorimeter, a Transition Radiation Detector, and a Timing Charge Detector to measure charge and energy. Galactic cosmic ray propagation models make predictions that fit current low energy spectra. With the high energy data collected from the first CREAM flight, we determine whether these predictions continue to agree with measurements at energies above 1 TeV.
