AC4 Lifetime Case 1: Panel-Deployed Cube • With an 50th percentile atmosphere assumption (nominal solar activity), the orbit lifetimes shown in TRACE and MEANPROP compare well • Ap panel-deployed p y cube byy itself will de-orbit within 25 yyears after launch • Orbital Lifetime = 12.3 years John.P.McVey@aero.org Alan.B.Jenkin@aero.org 5

AC4 Lifetime Case 2: Non Panel-Deployed Cube • With an 50th percentile atmosphere assumption (nominal solar activity), the orbit lifetimes shown in TRACE and MEANPROP compare well • A panel panel-deployed deployed cube will de de-orbit orbit within 25 years after launch even if the side panels do not deploy • Orbit Lifetime = 21.2 years John.P.McVey@aero.org Alan.B.Jenkin@aero.org 6
